• Condensing Boiler Flue Gas Temperature

2020-6-12 · The fuel used for boiler operation was Natural gas. Observation: Boiler was in operation with conventional economizer. De-aerator with 105 Deg C of feed water was fed to economizer and flue gas of 250 Deg C enters Economizer. Post economizer flue gas temperature drops to 150-160 deg C and this flue gas vented to atmosphere. VIEW DETAIL

A flue gas analysis of a gas-fired boiler indicates that the CO 2 content is 8% with a gas flue temperature of 204°C (400°F). Determine the overall thermal efficiency of the boiler. Solution. By reading the monograph of Fig. 8.12 the combustion occurs with an excess air of 48% and excess O 2 of 7%. The overall boiler thermal efficiency is about 81%.

The flue gases should leave the boiler at a temperature as low as possible to minimize the flue gas losses. Usually either economics equipment or corrosion issues limit the flue gas to 150200°C. Neither all of the carbon nor all of the carbohydrates in the fuel fed into the boiler will combust.

• Stack Losses for Low Sulphur Diesel Oil

It is important that measurements of flue gas temperature and composition be representative. There may be stratification in the gas duct particularly at low loads. Sampling at a few different locations in the gas duct is desirable. Convert to °F: °F = [ (°C x 1.8) + 32] if FGT and CAT are measured in °C.

Flue Gas Temperature. The flue gas temperature is the temperature of the combustion gases as they exit the boiler. If the flue gas temperature is high then it is often associated with heat being lost. Flue gas economizers can be installed to recover heat and enhance the overall . Radiation and Convection Losses

Selective non-catalytic reduction involves the injection of a NOx reducing agent such as ammonia or urea into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.

• Flue Gas Exhaust Thermometer - Controlled Combustion

A flue gas exhaust thermometer should be installed near the base of the breeching near the boiler to monitor the outgoing temperature of flue gasses. High flue gas temperature is typically an indication of soot build-up in the fireside of the boiler that causes reduced boiler efficiency corrosion failure of steel reduced heat transfer rates to the waterside of the unit draft loss excessive fan power consumption

Even with well-adjusted burners providing the minimum flue gas temperatures while achieving complete fuel combustion the exit temperatures of the flue gas may normally range from 175ºC (350ºF) to 260ºC (500ºF). Still there is ample room to recover some of this heat that would otherwise "go up the stack."
