Analysis on Variable-Pressure Operation and Energy-Saving Techniques for a Supercritical Steam Power Generation Unit
摘要
Abstract
The variable pressure operation and energy saving effect of a supercritical steam power generation unit, by timely adjusting the unit load through changing the condensed water Oow, are analyzed systematically. Based on operation data, several related factors are described in detail, such as the range of controlled load, the responding speed, the energy efficiency, the waler level control in the deaerator, condenser and low pressure healer, and the imparts of variable pressure operation on boiler operation characteristics. With the combination of load, adjustment by condensed water flow control and traditional technologies, the complete variable-pressure operation of a supercritical unit can be achieved, which is of great significance to energy conservation for large coal-fired power generating units.关键词
