The current set of problems in the field of heat power engineering has remained unresolved for many years. Ecological modernization of fixed assets of heat supply enterprises is defined as the main direction of ensuring the activities of regional heat supply systems in this article. The subject of the research is a set of theoretical, methodological and practical issues of the analysis of indicators of the ecological and economic efficiency of the boiler house modernization project. The purpose of the study is to analyze the ecological and economic efficiency of the project for the modernization of boiler houses to replace coal with more environmentally friendly fuels. The study has been carried out using a set of methods: comparative analysis, analysis of structure, financial analysis. The use of solid biofuels makes it possible to reduce the anthropogenic load from heat supply enterprises. The ecological effect consists in the reduction of total emissions into the atmosphere by 69 times or by 321 tons per year of the boiler house on bit fuel compared to a similar boiler house on coal. The economic effect for the boiler house lies in the possibility of saving on fees for the negative impact on the environment, depending on the fuel used. The calculations show that payments for negative impact on the environment have a small share in the cost of steam and hot water production by boiler houses. In this connection, this cannot become a motive for reducing the negative impact. It is necessary to establish standards for the negative impact and waste disposal at a minimum level in order to form a material interest among economic entities in reducing the anthropogenic load on the environment. The author has calculated the environmental and economic indicators of the project for the modernization of regional heat supply systems, based on the transition from using coal as the main fuel. This calculation can become the basis for the state program for the modernization of thermal energy

Приведены результаты исследований по разработке метода очистки геотермальных метанолсодержащих сточных вод (МСВ) объектов по добыче углеводородов, подготовке и транспорту газа. Разработана технология очистки МСВ, основанная на преобразовании метанола в легколетучий метилнитрит. Использование метода позволяет довести содержание метанола в очищенной воде до уровня ПДК и дополнительно проводить регенерацию метанола и одного из основных реагентов - нитрита натрия. Проведена оценка экологического и экономического эффекта от его внедрения.

Eastern Europe, extending from northern Russia to Czechoslovakia and Bulgaria, embraces a wide range of climates, all experiencing wider extremes of temperature and humidity than the maritime climates of the West. Noteworthy technological features of horticultural production include the development of walk-in plastic tunnels supported on tubular metal frames, the use of power station waste water for greenhouse heating, and the large-scale use of peat as a substrate in place of soil.

The main factors of choice of thermal energy source for residential and public buildings in case of central heat supply unability are viewed. The current regulatory documents of the Russian Federation in the matt er of design of decentralized heat supply sources - independent boiling rooms and individual boilers - are analyzed. The comparative analysis of proposed fi ndings is made.

The scheme of the high power boiler- house with cogeneration heat pumping plants for the two-tube system of heat supply is proposed. The application of cogeneration heat pumping technology without production of goods electrical power provides for the considerable economy of gas and increases the reliability of heat supply.

Abstract Priority and qualitatively new direction in the fuel and energy sector is renewable energy. This paper describes a feasibility study of using solar window in the system of solar heat supply. The article presents literature data about the effectiveness of the use of solar systems in other countries. The results confirm a sufficient efficiency of solar heat supply with using solar Windows. Insights based on practical experience and mathematical calculations, which are aimed at a detailed explanation of economic efficiency of the proposed construction.
