Why are induced draft cooling towers more efficient?
More efficient compared to forced draft cooling tower. Employs 50\% less energy while comparing to forced draft design. Contains a fan located on the top, which drives the air via the fills. Placement of an inlet fan on the top of the cooling tower, which creates low pressure.
Why is include Draught considered better than the forced Draught?
Which draught system is also known as turbine draught?…
| Q. | Why is induced draught considered better than the forced draught? |
|---|---|
| A. | because power requirement is high for forced draught |
| B. | maintenance of induced draught fan is costlier |
| C. | forced draught is less efficient |
| D. | forced draught produces less amount of speed of air |
How does a forced draft cooling tower work?
The forced draft cooling towers remove low-potential heat generated in the production process. A counterflow of air and hot water in the cooling fill results in a heat transfer. The air flow is provided by a propeller fan while the drift eliminators prevent the transfer of small the tower space.
What is the function of forced draft fan?
Forced Draft Fans (FD) supply the air necessary for fuel combustion by pushing air through the combustion air supply system and into furnace. These fans are located at the inlet of boiler to push high pressure fresh air into combustion chamber, where it mixes with the fuel to produce positive pressure.
What are the disadvantages of forced Draught cooling tower?
In the forced draft cooling towers the blower type fans are mounted on the lower side of the tower (see Fig. Though these fans consume less power as they operate in cooler air, such a design has the disadvantages of air distribution problems, leakages and recirculation of the hot and moist air back to the tower [10].
Why are cooling towers used in thermal power plant?
A cooling tower serves to dissipate the heat into the atmosphere instead and wind and air diffusion spreads the heat over a much larger area than hot water can distribute heat in a body of water.
What is a forced draft cooler?
The forced draft cooling towers remove low-potential heat generated in the production process. They use atmospheric cooling with wet technology and forced draft. A counterflow of air and hot water in the cooling fill results in a heat transfer.
