VWKG Type

Chimney boilers for heat utilization of flue gases type VWKG. The automatic flue gas boiler is a heat tube boiler that uses waste heat from internal combustion engines. Using boilers is particularly advantageous where a continuous source of heat is required. Operation in the overpressure mode on the flue gas side with correctly calculated dimensions of the heating surfaces ensures an ideal use of the heat of the flue gases and, thus, high efficiency.
