Pollution Control in Boilers | Just Venting

Apr 25, 2020 · emission in thermal power plants. Since the middle of last century, the research on the control of coal-fired flue gas has developed rapidly. The conventional desulfurization methods in power plants can be divided into wet, dry and semi-dry methods according to the use of reagents and the shape of final products in the desulfurization process.

How to Desulfurize Coal Fired Boiler

There are many desulphurization methods for coal fired boilers, but there are three kinds of commonly methods, pre-combustion desulfurization, desulphurization in the furnace and flue gas desulphurization, and the most widely used is desulfurization in the furnace. ZBG mainly adopts furnace desulphurization instead of flue gas desulfurization, because it is selected from the cost budget of the customer and combined with the design structure of the boiler itself.

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

A Discussion about Strategy of Flue Gas Dust Removal for

For a typical coal-fired power station, flue-gas desulfurization (FGD) may remove 90 percent or more of the SO 2 in the flue gases. History. Methods of removing sulfur dioxide from boiler and furnace exhaust gases have been studied for over 150 years.

Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
