一次网抽回水供热设计

Design for heating supply of pumping backwater from primary network

针对集中供热区域中一些远离负荷中心采暖用户问题,提出了采用一次网抽回水方式供热的解决方法,着重介绍了系统的设计参数,并对设备的选择方法进行了阐述,实践证明:采用一次网抽回水供热系统提高了发电厂供热能力,扩大了供热面积。

According to some problems of heating customer far away from loading center of some heating supply areas, the paper points out the so- lution of the pumping backwater from the primary network to the heating supply, mainly introduces the design parameter of the system, illustrates the selection methods for the equipment, and proves by the practice that the pumping backwater from the primary network heating system can en- hance the heating supply capacity of the power plants and enlarge the heating coverage.
