G4-73 and Y4-73 boiler pass, induced draft fan is suitable for power plant 2 ~ 670T / h steam boiler pass, induced draft fan systems. In no other special requirements, G4-73 can be used for mine ventilation and general ventilation. Fan transmission medium is air, the maximum temperature should not exceed 80 ℃; media induced draft fan for conveying gas, the maximum temperature should not exceed 250 ℃. Before the induced draft fan Zibo boiler turbine prices, dust removal device must be installed to minimize the fan into the dust content in the flue gas. According to the general plant use M5-29 pulverized coal boiler fan, dust removal efficiency of not less than 83%. After installing a new boiler blower fan, took place excessive or insufficient flow fan phenomenon boiler manufacturers, the main reasons are the following: 1, the pipe network resistance difference between the actual value and the calculated value is too large. General characteristics of the network equation P = KQ2 (K is the drag coefficient) shows that, if the actual value is less than the calculated value of K K, the flow rate increases; if the actual value of K K is greater than the calculated flow reduction. 2. Select the fan itself is not considered when the full impact of the deviation △ P pressure, and when the fan total pressure is positive deviation, then the flow rate increases; negative deviation, then the flow is reduced. When the fan is a new installation began formal operation, or the occurrence of excessive or too small flow during use, one of the following methods can be eliminated.
