【 摘 要 】

This work is devoted to the determination of the volume and composition of emissions into the atmosphere during the combustion of solid fuels (coal, wood) in house furnaces and small boilers with capacity till 1 Gcal/h. The relevance of this work is stipulated by the fact that a large number of small boiler operate in Russia, especially in rural and decentralized areas of energy supply. In addition, each city has many private residencies heated by wood and coal-burning house furnaces. The large coal reserves, as well as its low cost, make it a priority fuel, especially in the eastern regions of the country. When coal and wood are burnt in small heat sources, the resulting emissions enter directly into the atmosphere surface layer, where human activity is carried out. Thus, using the example of Irkutsk Oblast, it has been demonstrated that the burning of high-ash Cheremkhovsky coal in house furnaces produces the estimated amount of emissions that is 4.4 times higher than that produced by small boilers. Such amount of emissions is due to the low efficiency of coal combustion. As a result, conducting environmental assessments of the impact of small boilers and house furnaces on the environment help formulate the main environmental problems and determine the range of issues that need to be solved.
