Principals of Condensing Boiler System Design

2017-6-16 · boiler heating water system as a whole. Condensing boilers require entering water temperature (EWT) in the 100˚F (55˚C) range to actually condense water out of the exiting flue gas. The onset of condensing is with an EWT of about 130˚F (54˚C), but maximum efficiency occurs at an EWT of 80˚F (27˚C) or lower.

Flue_gas_stack : definition of Flue_gas_stack and

A flue-gas stack is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler, or other large combustion device.

Flue Gas Conditioning - EPA

Flue gas temperature affects the electrical properties of the ash. Measurements have shown a variation in resistivity with gas temperature with a maximum around 150°C to 200°C (300°F to 400°F). High sulfur coal with low exit gas temperature produces low resistivity ash which may be too low for the ESP.
