Primary Air Fan and Secondary Air Fan are the different names of Forced Draft Fan. They all may be installed in the same Steam Boiler Assembly but they all operate at different levels of flow (m3/hr) and Head generated (mmwc).
Forced Draft Fan is a type of fan supplying pressurized air to a system. In the case of a Steam Boiler Assembly, this fan is very important. As we know, for a Steam Boiler to generate steam, combustion must occur, be it any fuel (wood/coal/rice husk/pet coke/LDO/Furnace oil)
Carry out energy-saving renovation of fans.
Improve the management level of high-end equipment operations!
The design of fan parameters must be reasonable.
Optimize the design of the ventilation system.
Choose the appropriate fan adjustment method！
Improving the actual operating efficiency of fans plays a vital role in achieving the goal of energy saving and consumption reduction for enterprises. Enterprises have a great demand for energy saving in fans, so how can we improve the operating efficiency of fans to achieve energy saving?
When fans are classified according to pressure, those with a pressure lower than 15kPa are called ventilators, those with a pressure between 15kPa and 350kPa are called blowers, and those with a pressure higher than 350kPa are called compressors.
A fan is the abbreviation of equipment that converts mechanical energy into gas pressure energy and kinetic energy. According to the working principle and gas pressure, it is classified as follows:
