Experiment and Analysis on Flue Gas Low Temperatur

2013-12-24 · the exhaust gas temperature in many thermal power plants is much higher than the designed value, thus, the recycle and reuse of the waste heat of tail flue gas is necessary. However, lower exhaust gas temperature will aggravate low tem-perature corrosion of the tail heating surface, which also causes huge economic losses.

Reasons for Increasing Exhaust Gas Temperature o

The heat loss of exhaust gas is the biggest one of all the heat losses of boiler. Generally the loss heat is 6% of the heat input into the boiler furnace. The heat loss of exhaust gas increases by 0.5% when the temperature of exhaust gas increases 12-15%. Therefore, exhaust gas temperature is one of []

2010-7-20 · In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called "Ultra-Low NOx" (ULN) requirements, typically less than 10-12 ppm. It is widely believed that the ULN

Boiler - Wikiped

2019-10-9 · Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber.
