US4659305A - Flue gas recirculation system for fire tube

A flue gas recirculation system for fire tube boilers includes a duct connected to the boiler gas discharge stack and to a fan. Another duct couples the fan to a specially designed burner in the boiler. Recirculated flue gas 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.
