Discussion on heating system design for thermal power plant bunker bay

Discusses the heating system design scheme of high-zone and low-zone in thermal power plant, and presents the feasibility of using bypass pipe pressurization to solve the problem existed in combined heating network. Through using the pressure diagram, analyses the determination principle of regulating range of dynamic pressure curve, and makes the technical and economic comparison with other design schemes. Obtains that the heating system design of power plant high-zone should firstly select the bypass pipe pressurization technology and then the direct connection heating unit.
