What is the difference between natural and forced draft cooling tower?
Natural draft towers rely on a “chimney effect” to obtain circulation of the air through the water. Mechanical draft towers use fans to move the air and are subdivided into forced-draft or induced draft towers.
What does induced draft mean?
Definition of induced draft : a draft produced by a suction steam jet or fan on the stack side of a furnace.
What are the different types of Draught?
Types of Drought
- Meteorological Drought.
- Agricultural Drought.
- Hydrological Drought.
- Socioeconomic Drought.
- Ecological Drought.
What is an induced draft cooling tower?
What is an Induced Draft Cooling Tower? An induced draft tower is a type of mechanical draft tower which has one or more fans, located at the top of the tower, that draw air upwards against the downward flow of water passing around the wooden decking or packing.
What is the difference between a natural and induced draft condenser?
Natural draft cooling towers make use of the chimney operation of the cooling tower. The air flow is caused by the temperature difference between the air inside and outside the cooling tower. The fans used in mechanical draft cooling towers cause the air flow.

What is forced Draught ventilation?
1. Forced Draft Ventilation Ventilating is the process of changing or replacing air in any space to control temperature or remove moisture, odors, smoke, heat, dust and airborne bacteria. Ventilation includes both the exchange of air to the outside as well as circulation of air within the building.
What is induced Draught and forced Draught?
Forced draft: When air or flue gases are maintained above atmospheric pressure. Normally it is done with the help of a forced draft fan. Induced draft: When air or flue gases flow under the effect of a gradually decreasing pressure below atmospheric pressure.
Why is induced Draught considered better than forced Draught?
By what is natural draught produced?…
| Q. | Why is induced draught considered better than the 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 |
| Answer» a. because power requirement is high for forced draught |
What is the difference between crossflow and counterflow cooling towers?
In a crossflow tower, air travels horizontally across the direction of the falling water. In a counterflow tower, air travels vertically upwards in the opposite direction (counter) to the direction of the falling water.
What is Idct power plant?
The indirect dry condensing system couples an indirect dry cooling tower (IDCT) with a steam surface or jet condenser, and is suited for large capacity condensing units. Its tall concrete or steel shell eliminates hot air recirculation.
What is mechanical Draught?
It is a draft used in some gas burning appliances and cooling towers to remove flue or vent gases by mechanical means, such as a fan, which may include an induced draft portion under non−positive static pressure or a forced draft portion under positive static pressure.
What is the difference between induced draught and mechanical draught?
The draught, produced by means of a fan or blower, is known as mechanical draught or fan draught. The fan used is, generally, of centrifugal type and is driven by an electric motor. In an induced fan draught a centrifugal fan is placed in the path of the flue gases before they enter the chimney.
What is the difference between forced draft and induced draft?
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. It’s not always either-or.
What is induced draught fan?
The induced draught fan sucks the burned gases from the furnace and the pressure inside the furnace is reduced below atmosphere and induces the atmospheric air to flow through the furnace. The action of the induced draught is similar to the action of the chimney.
What is the difference between forced draft and induced draft cooling towers?
Here are some of the points in which the two types of cooling towers can be compared for best possible selection for your industry: Forced draft emphasizes on the chimney effect and air flow is natural whereas in the induced draft the drought of air is created mechanically by a fan.
