Research on Adding Post-unit for Back Pressure Steam Turbine

Abstract

Abstract

Introduction In order to solve the problem of changing the external steam supply of the unit from industrial steam to heating steam ， a thermal power plant is taken as an object to carry out technical feasibility study.
Method Four kinds of schemes including the control valve group， the two-cylinder steam turbine， the post-unit back pressure steam turbine shared by the whole plant， and the steam-driven feed water pump unit with generator were compared and analyzed.
Result Considering the characteristics of the schemes and project practice， the scheme of post-unit back pressure steam turbine shared by the whole plant is selected.
Conclusion The scheme is based on the principle of energy level cascade utilization， which is reliable in operation and economical. It also provides a useful reference for the comprehensive steam supply transformation of subsequent units.
