D20 Multistage centrifugal blowers
Multi-stage centrifugal blowers are widely for various smelting blast furnaces and iron furnace blast furnaces. And they are supporting coal washing jigs, mine flotation, sewage aeration, and chemical gas production, etc. Besides, this series of blowers have the characteristics of high efficiency, low noise, stable operation, few wearing parts, and easy installation, operation and maintenance.
Multistage centrifugal blowers
This series of blowers are multi-stage, single-suction, double-support structure. And, the blower adopts Coupling transmission and the directions of the air inlet and the air outlet are in the form of Figure 1-4. From the motor side, the blower rotates clockwise. Besides, there are two types of fans: high speed and low speed.

Forced/Inducted draft fans 1 Energy-saving analysis of boiler forced/inducted draft fans in thermal power plants 1.1 The importance of energy-saving design.In the thermal power generation technology, the boiler forced/inducted draft fan is an indispensable auxiliary device to ensure the normal operation of the generator set, and the electricity cost brought by the boiler fan makes it occupy a prominent position in the strategy of energy saving and emission reduction. Industry data shows that among the various operating equipment of thermal power plants, the electricity consumption of boiler fans can account for more than 40% of the electricity cost of the entire power plant. Once the boiler fan selection, technical parameter control, and equipment operation and maintenance problems occur, it will not only increase the comprehensive cost of power generation and the operating cost of thermal power plants, but also cause a series of problems such as waste of resources and increased non-functional consumption[1] . From an energy-saving perspective, technicians need to fully consider the energy-saving scheme of boiler fans, and take the current energy consumption status of boiler forced/inducted…
