Primary air fans Primary air fans (PA) are high pressure fans used to supply the air for the transportation of coal directly from the pulverizer to the furnace . These fans provide a positive pressure upstream of the coal pulverizer and handle relatively clean air .
What is the function of PA fan?
Primary Air Fans or PA Fans The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant.
What is SA fan in boiler?
Secondary fans play an important role in power plants. The fuel inside the furnace can be burned with the help of the secondary fan. When required, the SA fan is used to increase the air flow to improve efficiency and save fuel.
What is difference between ID fan and FD fan?
The key difference between a forced draft and an induced draft fan is, FD fan forces outside air into the heating system whereas an ID fan draws flue gases from the system out into the atmosphere. As compared to ID fans, FD fans are more efficient, easier to maintain, and have cleaner operating conditions.
Which powerplant has minimum operating cost?
Which power plant has minimum operating cost? Explanation: Hydroelectric power plant has lowest running cost because it does not needs any fuel and can be operated by few number of persons. Nuclear gas and thermal power plant requires fuels also the handling cost of fuels is added with the total cost. 3.
Which motor is used in ID fan?
3.2 kW Stainless Steel Electric Motor ID Fan, For Industrial
| Usage/Application | Industrial |
|---|---|
| Type | Duct Mounted Fan |

What is the difference between forced draft fan and induced draft fan?
Forced-draft fans focus the pressure and volume at the outlet of the fan to push air through a system, creating positive air pressure. Industrial induced draft fans operate by focusing the pressure and volume at the inlet of the fan to pull air through a system.
What is primary and secondary air?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.
Which power plant has longest life?
The components of a hydroelectric power plant including turbine, generator and the concrete dam are so resilient in construction that their life may be as long as 100 years or even longer.
Which power plant has highest capital cost?
Hence, according to the question, Nuclear Power Plant has the highest initial cost and minimum cost of fuel transportation.
What is id draft fan?
Draft, is commonly referred to as the difference between the atmospheric pressure and the pressure existing within a flue gas passage or the furnace of a boiler system.
