Industrial Enterprises

As industrial production expands, infrastructure develops, and new technological equipment is put into operation, energy needs increase, which means that the role of reliable energy supply to industrial enterprises increases. Electricity is used to light the territory of the enterprise, workshops, and laboratories, operate machines and mechanisms, automatically control the heat supply of premises and other technological processes. The level of reliability and security of heat and electricity supplies determines the stability of the enterprise and its economic efficiency. (Research purpose) The research purpose is in studying the economic efficiency of using own thermal power plant based on a gas turbine power unit. (Materials and methods) The article presents the advantages of using own thermal power plant that runs on natural gas. The most efficient balance of heat and electric energy production was determined. (Results and discussion) The article presents the construction of thermal power plant for the heat supply of buildings and structures defined by the project on the territory of the Federal Scientific Agroengineering Center VIM. The article considers the emerging trend of industrial enterprises building their own power plants, which make it possible to provide themselves with heat and electricity independently and guarantee more reliable operation of workshops by reducing downtime and disruptions of technological processes. (Conclusions) The use of a thermal power plant based on a gas turbine power unit will allow to get an annual profit, ensure energy independence, increase the reliability of power supply, and increase the profitability of production. Many large enterprises, pursuing economic goals, along with their own electricity supply, supply «excess» energy to centralized networks, often the level of energy supply «for export» significantly exceeds the level of their own consumption.

Introduction. Coal heat power stations are characterized by severe hazardous eff ect of occupational environment on workers. Objective. To analyze chromosomal disorders in workers of thermal power plant working on coal from Kuznetsk coal fi eld (West Siberia). Materials and methods. Th e authors studied level and specter of chromosomal aberrations in blood lymphocytes of 185 workers of Kemerovo thermal power plant and 218 inhabitants of the same location, not working on industrial enterprises (Kemerovo, Russia). For every individual, average number of 200 metaphase plates of high quality was analyzed. Results. Findings are that the workers of thermal power plant have levels of chromosomal aberrations signifi cantly higher than those of reference group (3,01±0,13% vs. 1,45±0,08%; р<0,00001). With that, increased frequency is seen both for chromatid aberrations and for chromosomal ones — that indicates complex exposure to chemical and radiation factors. Conclusions. Th e results obtained necessitate elaboration of measures to decrease genotoxic hazards in the occupational environment.

Basic Principles

The article deals with the issue of using a thermoacoustic engine as a low-power cogeneration source of energy for autonomous consumer power supply capable of operating on various types of fuel and wastes subject to combustion. The analysis of the world achievements in this field of energy has been carried out. A number of advantages make it very promising for developing energy sources capable of complex production of electrical and thermal energy with a greater efficiency than that of present day thermal power plants. The proposed scheme of a thermal power plant is based on the principle of a Stirling engine, but it uses the most efficient and promising thermoacoustic converter of heat into mechanical vibrations, which are then converted into electric current. The article contains a mathematical apparatus that explains the basic principles of the developed thermoacoustic engine. To determine the main parameters of the thermoacoustic engine, the methods of computer modeling in the DeltaEC environment have been used. A layout diagram of the laboratory sample of a thermal power plant has been proposed and the description of its design has been given. It has been proposed to use dry saturated steam as the working fluid, which makes it possible to increase the generated power of the thermoacoustic engine.

The quantitative chemical analysis of snow cover has been carried out for the Vorkuta agglomeration territory. The on-site ingress of pollutants in close proximity to industrial enterprises in Vorkuta is calculated. The schematic maps of substance distribution in snow in the studied area are built using space images. The control levels of aerotechnogenic pollution are established for the city, industrial zones and adjacent territories for the purpose of subsequent ecological monitoring. The pH value of snowmelt water reaches 6.5-7.2 due to a high content of alkaline components (calcium and magnesium carbonates) in snow. The snow cover of the Vorkuta agglomeration is highly enriched with heavy metals. The maximum permissible concentrations are exceeded for manganese, nickel, aluminum, vanadium, molybdenum and mercury. High concentrations of mercury in snow are supposedly related to coal combustion at the thermal power plant. After that mercury may be occluded on a surface of coal particles and ashes. It is shown that it is possible to establish the zones of the greatest aerogenic impact according to the content of mercury and vanadium in the snow. Factor analysis was used to identify the mechanisms of pollutants and factors forming the chemical composition of the snow cover. The share of elements in the suspended solids is more than 60% of their total content in snowmelt water. High concentrations of suspended particles (up to 720 mg/dm3) were observed in the snow of Vorkuta. The most severe pollution of the snow cover is registered in close proximity to thermal power plant №2. According to the calculations of the total pollution index, the highest excess of substance increment over the background level was noted in the sanitary protection zone around the thermal power plant №2.

The Impact

The main sources of thermal energy for the heat supply of cities and settlements are fuel-based thermal power plants and boilers. The article provides an analysis of the energy balance of a power plant in connection with the need to minimize the cost of fuel and electricity for heat supply. New analytical expressions comprehensively characterizing the efficiency of a power plant are developed. The analytical assessment of the impact of energy costs for the boiler needs on the energy balance of thermal power plant is made; methods for constructing schemes of the energy balance of thermal power plant and assessment of fuel efficiency in the boiler are designed. Attention is paid to errors arising from the use of the calculated values of air suction in the gas path of the boiler, and not the actual ones. Therefore, it is proposed to change the method of measuring heat loss with flue gases in order to eliminate or reduce the effect of air suction on the measurement results, taking into account the part of the flue gas heat received by the air in the air heater and returned to the boiler through the burner. The methods increasing accuracy of calculations of energy efficiency of the technological processes which are key in the centralized heat supply of the cities and settlements are developed.

Operating Result

Gas pressure plays an important role in the economic efficiency and stability of the operation of gas-fired boiler. However, because of the inherent characteristic of gas booster which is introduced to regulate the pressure of gas, there is surge happened in gas booster, resulting in deviation of gas pressure from set value, even damage to device. To settle the problem of surge, an anti-surge control is designed based on the characteristic curves of gas booster. And the control strategy is applied in a thermal power plant with gas-fired boiler. The practical operating result shows the effect of the proposed method.
