The aim of the article is to develop scientific and methodological approaches for management decisions in production, statistical and mathematical information processing, forecasting and mathematical modeling, interpretation obtained in the process of experimental research, as organizational principles of environmental and economic activities of modern technologies in various fields, including, construction, housing and communal complex in industrial ecological management systems. The production of thermal energy at thermal power facilities of heat supply systems by means of reagent-free water treatment is an innovative technology that has already confirmed its right to exist. At the same time, some theoretical aspects of the process of magnetization of water, in connection with the adoption of certain management technologies, need further clarification. The paper draws attention to the fact that the relationships between field thermodynamics and field theory are represented by balance equations. It is proposed to carry out the effectiveness of environmental management in production in two directions: assessment of techno genic and ecological equivalence of water magnetization process - internal environment of heat supply systems, and assessment of economic and ecological equivalence of heat supply systems - external environment - device for magnetized water.

At present, environmental pollution by fuel combustion products is one of the key problems in the heat supply sector. It affects the entire population of the Earth. The purpose of the research is to substantiate the necessity of ecological upgrading of thermal power facilities in the Irkutsk region and using a part of municipal solid waste as an alternative fuel at thermal power facilities of the Russian Federation. The research shows that the use of the two kinds of fuel (solid biofuel and alternative fuel) can reduce the anthropogenic load. This measure can be a way of energy efficient disposal of accumulated and annually generated production and consumer waste. The transition to alternative fuels can be most efficiently implemented in boiler houses. This is due to lower capital investments in the modernization of boiler houses as compared to the modernization of thermal power plants. The calculations in the article confirm that the implementation of environmental modernization of regional heat supply systems is not economically beneficial for entrepreneurs. The state should supplement the methods of regulation with targeted co-financing of programs for the modernization of thermal power facilities in order to accelerate the processes of modernization of heat supply in the Russian Federation. At the same time, the recipients of support must comply with the established indicators further on.

The main task of energy-efficient heat supply is to ensure full compliance between the produced and consumed thermal power, subject to a minimum of reduced costs. To achieve this goal, various methods of central and local regulation are applied. Analysis of the thermal schemes of some cities in Russia showed that most of the heat sources of centralized heat supply systems are not able to support the design hightemperature graphs with central regulation. Therefore, the area of centralized qualitative method of regulation of heat load has decreased substantially. A perspective direction for the further development of heat supply systems is to appeal to the experience of foreign countries, i.e. the use of qualitative-quantitative and quantitative methods of central regulation and low-temperature heat supply. There is also an acute problem of the complete use of heat by consumers, since overstating of the temperature of the return water substantially reduces the efficiency of heat sources. A new formula has been obtained which makes it possible to predict the temperature of the return network water in variable operating modes of heating points. The resulting formula can be used to set up programmable regulators and will allow correcting irrational modes of operation of heat supply systems.

The article aims to identify patterns in the distribution of heating energy to consumers with a varying availability of regulation equipment under real conditions of a central heating network, as well as to compare the results of computer simulation with full-scale measurements. For computer simulation, well-known mathematical methods for calculating the load flow in hydraulic circuits were used. Experimental studies of the operation modes of heat supply systems were carried out using the data of the control and monitoring systems of thermal power plants using the Siemens Simatic PCS7 software, a Portaflow 300 ultrasonic flow meter, stationary electromagnetic flow transducers, verified and certified manometers and thermometers. The graphs of the actual hydrodynamic modes of the heating network under study were obtained at outdoor air temperatures from +8 to -37°C, as well as under abnormal conditions (temperature drop in the supply pipeline and pressure drop at the heating network input). It was proposed to use jointly the simulation by means of the JA_Net software and full-scale measurements of the thermohydraulic operating modes of a centralised heat supply system, whose consumers have a various degree of regulation equipment. It was shown that the proposed complex method of qualitative and quantitative assessment of the efficiency of district heating networks makes it possible to identify the features of control of their hydraulic modes when connecting new consumers with a varying degree of automation. According to the obtained characteristics of changes in the flow rate of the coolant in the consumers’ internal systems depending on the pressure drop at the tie-in point, the lack of response to emergency situations on part of the consumers whose heat supply systems are equipped with the means of qualitative and quantitative regulation of the heat load, is associated with the process of automatic adjustment of the degree of opening of flow controllers and control valves at individual points. In future work, we will develop guidelines for levelling the imbalance of the heating network under the conditions of uneven provision of facilities with automation equipment when implementing projects for the complex modernisation of heat consumers or connecting new facilities to existing heat supply networks.
