Abstract

The paper presents the results of developing designs of low and medium capacity heat generators. Vortex adiabatic combustion chambers are differentiated by the location of the axis of vortex motion of gases in the furnace space (horizontally and vertically). Depending on the thermal capacity of the boiler, the vortex chamber is located either next to the boiler (the boiler is a waste heat boiler), or is built into the furnace space of the boiler. Adiabatic vortex combustion chambers with horizontal axis of rotation of flue gases were developed for boilers with heat output from 0.1 to 0.7 MW. Experimental studies, tests in pilot-industrial and industrial conditions of heat generators operating on WCF showed their high technical efficiency (unburned carbon loss amounted to no more than 5 %, the efficiency of boilers 86 %), and the amount of harmful emissions in flue gases is significantly lower than the maximum allowable values (in 2–3 times)
