The problem of burning coals with a large content of dust fractions in boilers of low thermal capacity in the harsh conditions of the Far North is considered. New technical solutions have been proposed for the reconstruction of existing combustion devices in hot water boilers, which will reduce mechanical combustion failure and emissions of harmful substances into the atmosphere. To solve this problem, there are also proposals from the Government of the Russian Federation to consistently displace part of the volume of low-quality solid fuel from the sphere of "small energy" - the housing and communal services industry in the Far East, by replacing it preferably with gas. Considering that the process is long-term and labor-intensive, in this period and in subsequent years, such solid fuel will have to be burned in the housing and communal services industry, therefore, one cannot do without the introduction of rationalization and technical solutions to improve furnace processes.

Currently, the fuel balance of the Republic of Sakha (Yakutia) and Baikal-Amur Railway area involves cheap coals from eastern deposits, in particular Neryungrinsky deposit, which, as a rule, are supplied to the housing and communal services industry with a high content of dust fractions with particle sizes from 0 to 3 mm, in the amount of 40-50% or more. When using such coal fractions, combustion in the layer furnace is unbalanced, and the efficiency of boilers does not exceed the minimum 45-55%. The outgoing flue gases of boilers actively emit unburned solid particles and a large volume of harmful substances into the atmosphere, which leads to a deterioration in the environment of the Northern Territories.
