Benefitting from Flue Gas Re-Circulation - MCL Energy ...

May 07 2019 · Flue Gas Recirculation (FGR) is a combustion modification process for boilers that can increase boiler efficiency and steaming capacity while at the same time reduce particulates stack opacity and nitrogen oxide (NOx) emissions. One of the main drivers of this technology is the Medium Plant Combustion Directive [MPCD] which effects all steam plant over a MHW in

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.
