For fans consumed mainly by coal-fired power provided to reduce the fan work loss, improve energy conservation has an extremely important role according to efficiency. Due to rising environmental requirements for plant fans, the need to increase pressure on the fan. However, there will be problems in the choice of parameters, such as: the parameter is large, can not fit, etc.. On most fan margin pressure will more or less number exists. We added denitration system or dust, when the fan to transform into a fan and found the original fan pressure difference is very small, even in the original fans will be able to save power consumption conditions to meet normal operating requirements, but there is no pressure margins the amount. To this end, in addition to measures designed to re-selection, replaced with the new fan, the fan only partial pressure increases can meet the requirements of the transformation, which is the plant most needed and most welcome. For example: Do not change the diameter of the fan blades only replace the fan pressure increases to meet new fans 1 200Pa; and increase speed plus the fan impeller fan pressure to enhance the transformation to meet the requirements of new fans (for axial fans, it does not change the fan diameter, improving a fan speed, often resulting in pressure is too high, the result of reduced stall margin of safety. If we can improve the speed of a fan at the same time, by replacing the fan impeller blades approach to meet the requirements, it would be a good improvement. Engineers on the fan structure design, effectively improve the efficiency of the fan, in addition to ensure that the production needs, but also to achieve energy saving, environmental protection in response to the government's slogan, it should focus on the economic benefits not only for businesses, but should abide by the law, promote energy conservation.
