Coal Fired Boiler Emissions Test - EPA

Jun 15, 1994 · Entropy tested the exhaust gases from the Unit 1 coal-fired boiler. The furnace burns bituminous coal. Gases from the combustion furnace pass through two electrostatic precipitators (ESPs) to control particulate. Gases exiting the ESPs pass through a flue gas desulfurization unit (FGD), to remove SO2, and are then exhausted through a stack.

The above mentioned three m odes of dust removal can all satisfy the requirement of Indian coal fired boiler flue gas cleaning if selected properly. For electrostatic precipitators, due to specific charac- teristic of Indian coal and ash, size of ESP must be sufficiently large.

Figure 3 shows two typical layout of SCR system applied to coal fired boilers. The Low-Dust or Tail End option shows the installation of the SCR reactor after the air preheater (APH), Electrostatic Precipitator (ESP), and flue Gas Desulfurization (FGD) systems. This option requires the flue gas to be reheated to acceptable SCR temperatures,

How to Desulfurize Coal Fired Boiler

Liming 13:31:21. 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 …
