The Effects of Flue Gas SO 3 on the Operation of Coa

There exists a certain amount of SO 3 in flue gas discharged from coal-fired power plants. The implementation and "ultra-low emission" retrofitting of SCR in China greatly increased the concentration of SO 3 in flue gas, which will lead to fouling, erosion and plugging of the SCR reactor and the air preheater downstream. With the lowered dew point of the flue gas, the ammonia sliped from

Calculation and analysis of acid dew-poin

The current calculation method of the acid dew-point temperature of the flue gas is multifarious, and many formulas even exist obvious errors. In this paper, the representative method is used to calculate the acid dew-point temperature of the flue gas, and the Influence factors of the acid dew-point temperature are analyzed. Finally, the optimum calculation

Prediction of Acid Dew Point in Flue Gas of Boiler

2019-3-8 · The temperature of flue gas should be controlled to be higher than the acid dew point to avoid fouling and corrosion of heating surfaces in the second pass of boilers. Decreasing the temperature of flue gas in boilers is one of the most effective ways to improve thermal efficiency, enhance electrostatic precipitator efficiency, and decrease water consumption of the desulfurization tower.

US4205630A - Steam air preheater for maintainin

In a pulverized fuel-fired steam generator, a steam air heater is disposed in the air inlet duct to the main air heater. Steam from an auxiliary in-plant source or from the boiler itself is passed through the steam air heater thereby increasing the temperature of the air entering the main air heater. The flow rate of steam passed through the steam air heater is regulated to maintain the flue

Air preheater - Wikiped

2019-10-2 · Types. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation.
