Modernized UKS-M type boilers

Universal steel boilers are designed to the combustion of low quality coal, fine coal, brown coal and wood.

While selecting a central heating boiler, the thermal balance of the heated area should be taken into account. The rated thermal efficiency of the boiler should be higher by 10% than the calculated heat requirement of the heated rooms. The table contains approximate areas of heated rooms, which may be heated by UKS type boilers. These data, based on our long-standing experience in assessing the level of room insulation and heat requirement, are approximate and refer to rooms with a height of 3 meters.

UKS-M type boilers (universal water heating boilers using fine coal as fuel) and UKS-G type boilers (universal water heating boilers using fine coal as fuel; UKS-G type boilers have an upper boiler pass, i.e., the boiler pass is placed above the boiler furnace) are the modernized versions of UKS type boilers and are designed to the combustion of low quality coal, fine coal, brown coal and wood. Their modern construction and the application of a microprocessor controller and blower makes it possible to burn fine coal going from the top to the bottom. As a result, it has a significant influence on reducing the environmental pollution. These central heating boilers operate in an average 24h working cycle.
