Description
Summary:Commonly used thermal calculation methods are intended primarily for large scale boilers. Hot water small scale boilers, which are commonly used for home heating have many specifics, that distinguish them from large scale boilers especially steam boilers. This paper is focused on application of thermal calculation procedure that is designed for large scale boilers, on a small scale boiler for biomass combustion of load capacity 25 kW. Special issue solved here is influence of formation of deposits on heat exchanging surfaces on efficiency of heat transfer and on overall boiler efficiency. In the paper are presented results of mathematical model created for this purpose and its verification by experimental measurement in this specific boiler.
