US4659305A - Flue gas recirculation system for fire tube

A flue recirculation system for boilers includes a duct connected to the boiler discharge stack and to a fan Another duct couples the fan to a specially designed burner in the boiler Recirculated flue is injected downstream of the fuel/air mixture in the burner and cools the flame leading to substantially reduce the NO x content in the boiler stack emissions
