This paper presents the results of the influence of ultrasonic treatment in the cofermentation of the cattle manure mixture (cattle) with the leaven from the rumen of ruminants on the process of biogas production. Anaerobic digestion was carried out in matinence periodic operation at the mesophilic temperature of 38 C ̊. As a substrate, a mixture with a content of 70 % cattle manure and 10 % leaven from rumen of ruminants was used. Treatment with ultrasound of the mixture was carried out at an intensity of 10 W/cm2 and an amount of input energy of 9350 kJ/kg of dry matter (DM), which completely eliminated the processes of stratification and sedimentation. Decomposition of organic matter (OM) in the periodic regime with the enzyme and ultrasound treatment occurred within 8 days, the usual substrate during this time OM decomposed 3.0 times less (only 14 %). The process of fermentation of methane in continuous and periodic modes treated with ultrasound, as at other temperatures, was stable, as can be judged by the values of volatile fatty acids (VFA) Volatile fatty acids (VFAs), alkalinity, pH, and biogas. The energetical efficiency of methane fermentation is estimated by comparing the volume of fuel (biogas) and heat consumption for technological needs. As shown by the comparison of efficiency of different regime, the largest amount of commercial energy in the form of biogas was obtained in the mode of joint fermentation of a mixture of cattle manure (cattle) with a ferment from the rumen of ruminants treated with ultrasound – 3 times more than without treatment (space).

Among many environmental conditions that affect a person, the most important factor is nutrition. Today, there is no doubt that there is a direct link between nutrition, health and disease. Proper nutrition ensures normal growth and development of a person, contributes to the prevention of diseases, has a positive impact on life expectancy and creates conditions for adaptation to the environment. A very actual topic for public catering in the Republic of Kazakhstan, namely for fast food companies, is the development of new recipes and culinary products from relatively inexpensive vegetable raw materials, as well as qualitatively new food products with a purposefully changed chemical composition. One of the main ways of solving problems of expanding the production of products for quick service, as well as products for dietary and therapeutic and preventive nutrition is the use of sprouted grains and beans. In this article, poly-grain mixtures of sprouted wheat and extruded soy beans in different ratios are studied and considered. Poly-grain mixtures developed by us are balanced in nutrients, vitamins and amino acids. The research was carried out on the basis of the accredited testing laboratory of RUBICOM enterprise LLP and the scientific laboratory of the Innovative Eurasian University. The purpose of this work is to study a promising method for increasing the nutritional value of grain mixtures by extruding them at different temperature conditions. To achieve this goal, the following tasks were planned: – to study the grain of soy beans and sprouted wheat on the organolepti c characteristics and chemical composition of the poly-grain mixture; – examine the chemical composition of the poly-grain mixture before extrusion; – choose the optimal mode of the extrusion process; – study and analyze the chemical composition of poly-grain extruded mixture; It should be noted that we have developed for the first time the optimal technological mode of extrusion of poly-grain mixture from sprouted wheat and soy beans, and the physical and chemical composition of the poly-grain mixture was studied. The results of the research presented in this paper are the basis for the development of recipes and technologies for fast food products. The reliability and validity of scientific statements is confirmed by the choice of modern methods of chemical composition analysis.

Kazakhstan has a significant potential for grain exports. Grain exports are important for the country's economy. The country is one of the six largest grain exporters in the world. This is due to the high milling properties of Kazakh grain, the quality indicators of Kazakh flour are highly valued in many countries of the world, which allows Kazakh wheat to be competitive in the world market and provide markets in various countries of the world. The main export destinations are Uzbekistan, Afghanistan and Tajikistan. The article analyzes the main trends in the development of the grain market and gives an assessment of the state.

The main problem: This article is devoted to the key problems of the fuel and energy complex of the Republic of Kazakhstan: 1) lack of production capacity to meet the growing demand for energy and fuel from the economy and the population. Increased demand for electricity and heat, which will require the commissioning of new generating capacities.There is already a shortage in the fuel markets. Modernization and bringing the existing oil refineries (hereinafter referred to as refineries) to full capacity will not allow providing the domestic market until 2030; 2) the export orientation of raw materials, the dependence of the economy on the export of energy resources. In order to attract technology and investment in the oil and gas and nuclear industries, agreements on the extraction of energy resources were concluded with international export companies. In the medium term, Kazakhstan may face a shortage of oil for domestic refineries, if measures are not taken to stimulate its refining within the country. The uranium mined is fully exported; 3) high energy intensity of the economy, low level of energy efficiency. There is a high potential for increasing the efficiency of energy use both in the electric power industry and fuel production, and at the level of final consumption – in industry and housing and communal services; 4) decrease in the replenishment and quality of the resource base in the oil and gas, coal and nuclear industries; 5) low environmental friendliness of technologies used in the fuel and energy complex. Purpose: The purpose of the article is to reveal the problem in the field of ensuring the fulfillment of international obligations between different countries and their own energy sufficiency by gradually changing the structure of energy production. Methods: Studying the experience of increasing the efficiency of the use of energy resources and energy saving as a priority of the state policy of the country. Analysis of production capacity with a constantly forecasted shortage of primary energy resources and insufficient growth of capacity for the production of electricity and heat. Consideration of the possibility of compensating for the shortage by saving energy resources, increasing tariffs for energy carriers, as a stimulating factor for their effective use. Results and their significance: The results of this article will reflect the problems of energy, as the most important driving force of global economic progress. The well-being of the people depends on the state of the country's energy sector, therefore there is an urgent need to solve the emerging problems. The global energy problem is, first of all, the issue of stable and efficient supply of fuel and energy to mankind. Today, the energy sector of Kazakhstan is focused on fuel resources, since the country is provided with hydrocarbons and other energy resources. About 72 % of electricity in Kazakhstan is generated from coal, 12,3 % from hydro resources, 10,6 % from gas and 4,9 % from oil. Thus, the four main types of power plants generate 99,8 % of electricity, while alternative sources account for less than 0,2 %.

Singularly perturbed partial differential equations with small parameters with higher derivatives deserve special attention, which often arise in a variety of applied problems and are used in describing mathematical models of diffusion processes, absorption taking into account small diffusion, filtration of liquids in porous media, chemical kinetics, chromatography, heat and mass transfer, hydrodynamics and many other fields. It is necessary to consider the creation of an asymptotic classification of solutions of singularly perturbed equations using a well-known approach to solving the boundary value problem. In this case, the singular problem is understood as the problem of constructing the asymptotics of the solution of the Cauchy problem for a system of ordinary differential equations with a small parameter with a large derivative. The asymptotics of the solution in all cases is based on the last time interval or the construction of a boundary value problem for a system with a weak clot in an asymptotically large time interval. Purpose - to construct and substantiate the asymptotics of solving a singular initial problem for a system of two nonlinear ordinary differential equations with a small parameter; To date, a number of methods have been developed for constructing asymptotic expansions of solutions to various problems. This is the method of boundary functions developed in the works of A.B. Vasilyeva, M.I. Vishik, L.A. Lusternik, V.F. Butuzov; the regularization method of S. A. Lomov, methods of averaging, VKB, splicing of asymptotic decompositions of A.M. Ilyin and others. All the above methods allow us to obtain asymptotic expansions of solutions for wide classes of equations. At the same time, such singularly perturbed problems often arise, to which ready-made methods are not applicable or do not allow to obtain an effective result. Therefore, the development of methods for solving equations remains a very urgent problem. As a result of the study, an algorithm for constructing an asymptotic classification of the initial solution of the problem with a singular perturbation is given, and approaches to estimating the residual term are also shown.

Combustion engines operate over a wide range of power and speed. To the greatest extent, this applies to automotive and tractor engines and diesel engines operating at fractional and idle loads for a significant part of the operating time. When designing engines, the choice of their main design and layout parameters is carried out in a comprehensive manner, taking into account the provision of the required power and efficiency in the modes of maximum torque and rated power. However, ensuring the economical operation of modern highly accelerated diesel engines at low loads and idling causes a whole range of problems related mainly to the organization of effective mixture formation and fuel burnout, as well as to ensuring stable fuel supply. Thus, the cycle dose of injected fuel in idle mode is 8–12 times less than the cycle dose in nominal mode, which determines increased requirements for fuel equipment and difficulties in ensuring high-quality mixture formation. At the same time, diesel engines operate in idle mode up to 50 % of the total operating time, consuming up to 15–20% of the fuel. For truck engines, the relative idle time is approximately 20–25 %. Thus, the development of measures to improve the efficiency of diesel engines at idle is relevant. The purpose is to perform a numerical analysis of the effect of switching off cycles in diesel engines for autotractor and diesel locomotive purposes on the working processes in the cylinder and the indicator parameters of the cycle in idle modes. When writing the article, traditional methods (comparison, description, and measurement), generallogical methods and research techniques (analysis, generalization, etc.) were used. A numerical analysis of the operating cycle of a diesel engine equipped with a cycle shutdown system was performed. The relationship between changes in fuel injection characteristics when cycles are turned off with indicator indicators of the engine operating cycle in idle load modes is disclosed. It has been established that the expediency of switching off cycles in a specific engine operation mode is determined primarily by the features of the injection, carburetion and fuel burnout processes.

Main problem: The use of waste heat is most often solved by installing heat exchangers, but this is not effective when the temperature of this heat does not exceed 10-15 0 C, in which case this heat can be used using a heat pump. Where can I get this heat? Almost any enterprise needs cooling of any equipment elements or substances – working fluids; the heat received from them can be sent to a heat pump and used here at the enterprise. Purpose: Consideration of the possibility of using the heat of cooling water from the pump CNS 60-165 and the proposal of a new scheme with the installation of a heat pump that uses this heat. Methods: This is achieved due to the fact that it is proposed not to discard the heat, but after its use in the heat pump evaporator, transfer it to the heated medium - water, which is then sent to the shower cabins of the enterprise. Since the showers are located in the same room, the cost of transporting heat and losses will be minimal. Methods: In the course of the research, the possibility of using the waste heat of an industrial enterprise for using it here at the enterprise for the purposes of hot water supply was considered. For these purposes, it is proposed to install a heat pump, thanks to which the thermal potential increases, which makes it possible to fully use the received heat. Results and their significance: As the experience of foreign countries has shown, heat pumps can be widely used in many industrial enterprises, and in conditions of increased competitiveness, in order to reduce energy costs and the cost of manufactured products, install heat pumps to utilize excess heat, for example, process water, which is available in many production allows you to have a significant economic effect.

Main problem: recently, much attention has been paid to energy saving in production, especially when it comes to industrial units that burn fuel. There are several ways to maximize the use of the heat released during the combustion process, for example, to reduce the temperature of the flue gases at the outlet of the unit, by maximizing its use, both in the technological process itself and by installing additional heat-receiving units, for example, air heaters or other heaters. Another way to save money is to reduce heat losses through the lining of these high-temperature units. Metallurgical units that consume a large amount of energy and fuel require an analysis of their consumption, and ways to save their consumption based on the results of the analysis. Purpose: this article considers the possibility of replacing the existing inner insulation layer of the second and third sections of a high-temperature unit - a metallurgical furnace, with a new one with better technical and economic indicators. Methods: the possibility of replacing the existing inner insulation layer of the second and third sections of the high-temperature unit with a new one, with the best technical and economic indicators, was considered. The calculation of heat losses by thermal conductivity through the side surfaces and the roof with new insulation was performed, and the economic efficiency of the proposed solution was proved. Results and their significance: replacing the existing inner layer of insulation - refractory concrete PHLOCAST M30 (thermal conductivity coefficient from 1,4 to 1,45) with the proposed CERALIT GUN HK 70070 (thermal conductivity coefficient from 1,03 to 1,12) will reduce heat loss to the environment, and thus to reduce fuel consumption for the furnace.
