Heating station design of direct connection centralized heating network

Presents the features of direct connection heating system. To ensure the stability and safety of hydraulic and thermal regime of heat consumers in direct connection heating system, discusses the heating distribution station design. Taking a county-level city as an example, analyses the pressure diagram of different heat consumers and pressure conditions of first-level pipeline network, gives the design schematic plot of different kinds of heating distribution station. Analyses the advantage and disadvantage of the application of distributed variable frequency pump in direct connection heating system, and compares the initial investment and operating costs with the traditional system.
