Short description and main drawbacks of the K-50-14-250 steam boiler operation by fuels combustion with the vortex burner use In the production-heating boiler-house of the city Tashtagol (Kemerovo Region), related to Yuzhno-Kuzbasskaya Energy Company, LTD five K-50-14-250 boilers are installed. They are designed for hot water supply of the city and net output of steam for iron ore extraction mine. Steam double-drum vertical water-tube К-50-14-250 boilers with natural circulation, produced at Belgorod boiler factory, have a П-shaped layout and are designed for coal dust combustion. Originally the boilers were designed to burn natural gas and sour oil, however, they were reconstructed by the factory for burning hard coal.
