4 FAQs about Power plant flue gas drying and induced draft

What is a draught fan in a thermal power plant?

Draught fans are an essential and irreplaceable component of a thermal power plant. Reitz India manufactures draught or draft fans like primary / secondary fans (PA / SA fans) and induced / forced draft ( ID / FD fans) for thermal power plants.

What is a induced draft fan?

The Induced Draft Fan, also known as the ESP Fan (Electrostatic Precipitator Fan), plays a vital role in power plants. It helps remove flue gases from the boiler and directs them to the chimney. By doing this, it maintains a negative pressure inside the furnace, which ensures the proper combustion of fuel. Key Functions:

What is induced draft in a furnace?

Induced draft (ID) refers to the method of maintaining a negative pressure in a furnace by using an induced draught fan to suck the products of combustion out, thereby facilitating the exit of flue gas through a chimney and mixing it with the surrounding atmosphere. How useful is this definition?

What is a forced draught fan?

Forced draught fan is commonly referred as forced draft fan and induced draught fan as induced draft fan. Centrifugal fans are also called as radial fans and sometimes as centrifugal blowers. An FD fan draws air from the atmosphere and forces it into the furnace through a preheater.
