Abstract

The growth trend of individual housing construction in the country decides the socio-economic role in solving the housing issue of the population. The development of housing construction in Yakutia is characterized by ensuring the pace of construction and various social programs in rural areas. Due to geographic and transport and logistics difficulties, connecting many settlements and microdistricts to centralized power supply sources is difficult and incurs large budget costs. On the market there are various solid fuel heat generators of low power (up to 100 kW) with an upper fuel ignition method, using coal and wood fuel. Practice shows that these heat generators and their chimney systems experience difficulties when operating at low outdoor temperatures, which is reflected in the formation of soot on heating surfaces and acid condensate in chimneys. One of the reasons is the unsatisfactory mode of fuel combustion due to the design features of the boiler furnace. To study the influence of climatic and external factors on the operation of a solid fuel heat generator, during the heating period, measurements were made of the operation parameters of the boiler furnace and its chimney system. It has been established that with a decrease in the volume of fuel as it burns out in the furnace, the combustion temperature and heat output are significantly reduced, which is associated with an increase in the excess air coefficient.
