Improving the energy efficiency of low-power solid fuel hot water boilers

Abstract

The topical issue of efficient fuel combustion when using hot water boilers is considered. Indeed, this is a very important issue that is directly related to the rational use of resources, reducing the cost of providing thermal energy and reducing the negative impact on the environment. As a result, today the production and operation of hot water boilers must meet high standards of efficiency and environmental friendliness in order to ensure an optimal balance between economic efficiency and environmental protection. Moreover, the development of new energy-saving technologies and fuel combustion systems is an important area of scientific and technological progress to improve people's living conditions and ensure sustainable development. Burning fuel in large quantities leads to certain losses, which reduces the efficiency of the boiler. Therefore, there were mainly small energy-saving furnaces designed for burning fuel. The author proposed a small boiler with a furnace in which a vertical grate is used. Burning any fuel in such a furnace reduced heat loss by 2 times and harmful emissions into the atmosphere by 1.5 times. The efficiency of the heating processes in the boiler was evaluated during one heating season. The cost of providing thermal energy compared to other operating boiler houses amounted to 14400 somoni (1200 dollars), which is 18% less than the initial costs of previous years.
