The function of the induced draft fan is to exhaust the exhaust gas generated by coal combustion of the boiler into the flue and exhaust the air through the chimney. It needs to overcome the pipeline resistance from the boiler outlet to the chimney outlet, including the flue resistance along the way, the resistance of air preheater, denitration device, dust remover, desulfurization absorption tower, chimney and other equipment, which are widely used in thermal power coal-fired units, oil fired units, Circulating fluidized bed unit, etc. Generally, movable blade adjustable axial flow fan and stationary blade adjustable axial flow fan are selected.
The induced draft fan produced by SEBW is in the leading position in the industry, with a domestic market share of 30%. The flow applicable range of induced draft fan is 80-1100m3s, the pressure applicable range is about 5000-15000pa, and the unit coverage is above 150MW.
The centrifugal fan, he axial fan with adjustable blades and stationary blade adjustable axial flow fan produced by Shanghai electric blower Factory Co., Ltd. are imported from Germany TLT company. The technical parameters of the fan are wide and applicable; the advanced design, i.e. adopting the design concept of "tailor-made", makes better matching; the fan's curve is flat, the efficient area is wide, and the operation efficiency is high, all of which reach the national level I energy efficiency standard; the advanced anti-wear and anti-corrosion measures make the fan run more safe and reliable; the various adjustment methods realize stepless Adjustable, adjustable in motion, frequent adjustment, can meet the needs of different users.
