HEAT GENERATOR Russian patent published in 1997 - IPC

FIELD: generation of heating and drying gaseous agent; hot water supply for heating poultry-yards, farms, green-houses, etc. SUBSTANCE: cooled combustion chamber 7 of heat generator is assembled from thermosiphons with evaporative zone forming gas-tight passage for burning fuel and condensation zones made in form of finned tube bundle 9 which are brought in flow of gaseous heat-transfer agent. Additional condensing surface 15 built in thermosiphons is used for heating the running water. Change-over of circuit of flowing of radiation and convective heat exchangers of heat generator from parallel to series provides for two levels of air heating temperature. EFFECT: modification of heat generator enhancing reliability of cooling combustion chamber due to replacement of alloyed steels by carbon steels, low cost of units, extended functional capabilities due to heating of additional heat transfer agent providing for two levels of parameters of air heating for heating and drying (temperature disinfection); reduced number of items of equipment. 2 cl, 2 dwg
