Сжигание топлива в больших количествах при использовании водогрейных котлов приводит к определенным потерям, что снижает КПД котла. Поэтому для сжигания топлива были разработаны малогабаритные энергосберегающие печи. Автор предложил использовать малогабаритный котел с топкой с вертикальной колосниковой решеткой. Малогабаритный котел с водонагревателем с регулируемой колосниковой решеткой мощностью 50 кВт был установлен в здании школы-интерната. Сжигание любого топлива в такой топке привело к следующим результатам: а) производительность котлоагрегата увеличилась до 79–81 %; б) потери тепла сократились в2 раза, а вредные выбросы в атмосферу – в 1.5 раза. Затраты на обеспечение тепловой энергией по сравнению с другими действующими котельными составили 14 400 сомони (1 200 долл.). Это на 18 % меньше затрат предыдущего отопительного сезона без использования предлагаемого котла. Эффективность тепловых процессов в котле оценивалась в течение одного отопительного сезона. 

Burning fuel in large quantities when using hot water boilers leads to losses, which reduces the energy conversion efficiency of the boiler. Therefore, there were mainly small energysaving stoves designed to burn fuel. The author proposed to use a small boiler with a firebox with a vertical grate. A small boiler with an adjustable grate water heater with a capacity of 50 kW was installed in the boarding school building. Combustion of any fuel in such a furnace had following results: a) the productivity of the boiler unit had been increased to 79–81 %; b) heat loss reduced by 2 times and harmful emissions into the atmosphere in 1.5 once. The costs of providing thermal energy compared to other operating boiler houses amounted to 14 400 somoni (1 200 dollars). This is 18 % less than the costs of the previous heating season without using the proposed boiler. The efficiency of heating processes in the boiler was assessed during one heating season.
