Shandong Boiler fan factory direct telephone, Marriott produced by the boiler fan impeller, housing, air inlet, drive unit, and other components of regulation of the air so that, boiler fan is to adapt to various coal burning smoke and dust removal device (1 to 20 t / h) and the joint design of industrial boilers maximum total pressure efficiency of 90.5% of the new series Boiler Fan. Where the inlet conditions can be quite the performance but also the choice of even the fittest, but can not exceed the maximum temperature industrial boiler selection 250 ° C.5 ~ 35 t / h, the heart inlet conditions similar performance but also to adapt to those who can be selected, but the maximum temperature not exceeding 250 ℃. Shandong Boiler fan factory direct telephone, fans adapted with economizer (preheater) and Smoke and dust removal device, is the former Ministry of Machinery Industry fan energy group organized jointly design the fan industry, the State Economic and Trade Commission and Ministry of Machinery Industry Push efficient use of energy-saving products with high efficiency, low noise, smooth performance curve, efficient wide area characteristics. The fan is intended for use in industrial boilers run variable condition, the induced draft fan to work in the high zone, to achieve energy saving purpose and design. The current series of large industrial boilers burning coal for the merits of the poor, dust resistance with use of different air volume required to exhaust fans, the pressure difference is large, in order to adapt the above, taking into account the fan of the economy, with the exception of 20 tons of boiler induced draft fan power required for larger, but with (D type) Direct drive coupling, the rest are triangular tape (C-type) transmission, not only with a machine number of different speed to meet the same tonnage of boiler precipitator types of configuration requirements, reduce the number of fans of the series and the machine, but also facilitate the role of the unit in accordance with the actual situation of self-change spindle speed to achieve the desired ideal wind, air pressure.
