Investigation of the growth and removal of particles in

Boiler load is an important parameter of the unit operation that exerts a great influence on the flue gas flow rate, flue gas temperature, and pollutant generation. To further analyze the effect of temperature management on particle growth and removal, we study the changes in particle size and concentration at , 76%, and 65% boiler loads.

Fuel Ash Corrosion - The National Board of Boiler and

While the precise dew-point for sulfuric acid depends on the sulfur-trioxide concentration, at 10 parts per million sulfur trioxide in the flue gas, the dew-point is 280 o F. Dew-point corrosion is exacerbated in coal-fired boilers by the presence of fly ash. Fly ash accumulates throughout the flue-gas path, and the resultant deposit acts like

Coal fired boiler - Guideline for energy efficient

Flue gas temperature: Flue gas temperature to chimney must be as low as possible. Lower temperature in flue gas indicated higher energy conversion in boiler. acid dew point must be considered while lowering temperature. Flue gas heat may be utilized in preheating boiler feed water or combustion air.

The Flue Gas Leaving The Natural Gas-fired Boiler

The flue gas leaving the natural gas-fired boiler that you are designing should be at a high temperature because of dew point. Your boss asks you to examine that argument by performing some calculations. The natural gas boiler that you are designing uses a gas with a composition of CH4-95% and C2H6 – 4% and other inert gases 1%.
