Is flue gas harmful? | AnswersDri

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.

Flue Gases - an overview | ScienceDirect Topi

The energy generated from the incineration of solid wastes can be recovered as thermal energy, which is released from the flue gases exiting the combustion unit. Typically, the flue gases in WTE units are projected to range from 1,598 to 1,796°F (870 to 980°C) passing through the waste heat boiler downstream of the secondary combustion

Boiler Combustion | CleanBoiler.o

One technology that offsets the efficiency loss due to lower flame temperatures in a firetube boiler is flue gas recirculation. Although the loss of radiant heat transfer could result in an efficiency loss, the recirculated flue gases increase the mass flow through the boiler – thus the convective heat transfer in the tube passes increases.
