Gas burner, with counterflow heat exchanger for exhaust heat recovery, has parallel channels linking burner body with combustion chamber, and gas guide system to direct feed and exhaust flows

摘要

The burner has a burner body (10) and a combustion chamber (11) with parallel channels linking them together. The first section has gas feed channels to the combustion chamber and a second section has channels to lead the exhaust gases away from the combustion chamber. The burner body has a gas guide system (21) to give the gas feed and exhaust flows at the gas feed (23) and exhaust (22) zones.
