The role of the boiler induced draft fan, the role of the induced draft fan

The purpose of a blower is to deliver a certain gas to where you need it. As for what kind of gas it is, it depends on your needs.

For example: 1) Conveying air, mainly used to support combustion 2) Conveying reducing gas, mainly used to reduce a substance (usually metal) 3) Transporting protective gas (usually inert gas) 4) Other uses (such as: used for conveying powder materials, purging, etc.) Example:

Brushing to the boiling furnace is not only for combustion, but also for the purpose of lifting the material (similar to boiling) The medium conveyed by the induced draft fan is flue gas, and the maximum temperature shall not exceed 250 degrees.

The main function of the induced draft fan is to make the flue gas generated in the furnace can be smoothly discharged, and to maintain a certain negative pressure in the furnace, so that the boiler can have sufficient oxygen to get good and full combustion.

The role of the induced draft fan is; Overcome pressure losses in tail flues, dust collectors, air preheaters, etc. The flue gas generated in the furnace can be smoothly discharged, and a certain negative pressure can be maintained in the furnace, so that the boiler can be fully combusted. to improve economic efficiency.

The function of the induced draft fan is to exhaust the flue gas generated in the furnace and maintain a certain negative pressure in the furnace to overcome the pressure loss in the tail flue (including the dust collector). Also called a suction fan.

The boiler induced draft fan is used to maintain the negative pressure of the furnace, and the blower is to maintain the oxygen content of the furnace!

The blower is the blower, and the air sent to the furnace is the coal burning more vigorously, which is positive pressure; The induced draft fan is to transfer the flue gas out of the furnace, the furnace has a relative oxygen content, and the exhaust gas temperature of the flue gas can also heat the boiler for economic use.

The boiler induced draft fan is used to exhaust the flue gas in the furnace and maintain the negative pressure in the furnace.

Increase the oxygen content of the air.

The function of the induced draft fan is to remove the high-temperature flue gas generated by the combustion of the boiler, maintain the pressure of the furnace, form a flowing flue gas, complete the heat exchange of the flue gas and air without a bench, and discharge it to the flue through the dust collector to adjust the stability of the negative pressure of the boiler furnace. Induced draft fans are widely used for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boilers and industrial furnaces; Air conditioning, cooling, ventilation in Kuga equipment and household appliances, etc. <

Induced draft fans are widely used for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boilers and industrial furnaces; coarse rot of air-conditioning equipment and cooling and ventilation in household appliances; drying and selection of grains; Wind tunnel wind source and hovercraft inflation and propulsion, etc. The working principle of the induced draft fan is basically the same as that of the turbine compressor, but due to the low gas flow rate and the small change in pressure, there is generally no need to consider the change of gas specific volume, that is, the gas is treated as an incompressible fluid.

Boiler induced draft fan is a machine that relies on the mechanical energy input of the motor to increase the gas pressure and discharge the gas, which is a driven fluid machinery.

The working principle of the boiler induced draft fan is basically the same as that of the turbine compressor, but due to the low gas flow rate and the small change in pressure, there is generally no need to consider the change of gas specific volume, that is, the gas is treated as an incompressible fluid.

The induced draft fan of the boiler of a large power station is generally an axial fan with adjustable static blade or adjustable moving blade, which uses the lifting force generated by the rotation of the impeller to introduce the flue gas in the boiler into the desulfurization island or chimney along the axial direction.

Boiler induced draft fans are widely used for ventilation, dust removal and cooling in power production, factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boilers and industrial furnaces; cooling and ventilation in air-conditioning equipment and household appliances; drying and selection of grains; Wind tunnel wind source and hovercraft inflation and propulsion, etc.

An induced draft fan heater (also known as a blast heater) is a device used to heat air, and it typically includes a fan and a heat exchanger.

The main function of the induced draft fan heater is to draw cold air from the outside into the heater through the Ant Trace fan, and then heat it through the heat exchanger, and finally send the warm air back to the room. This kind of equipment is usually used in heating systems or industrial processes, which can increase the temperature of the indoor air and maintain a comfortable temperature environment, and can also heat some production processes that require high temperatures.

In the heating system, the induced draft fan heater also has other important functions, such as providing enough gas, coal gas or oil-gas mixture for the boiler or gas water heater to maintain the combustion process; In addition, it allows for more air flow and increases the efficiency of air circulation, which in turn improves the thermal efficiency of the entire heating system.
