Condenser with both heat supply and condensation functions

Abstract

The invention discloses a condenser with both heat supply and condensation functions. The condenser comprises a shell, a water chamber, a pipe plate and a cooling water pipe, wherein the water chamberis arranged on the outside of the pipe plate and comprises a front water chamber located on the left side of the shell and a back water chamber located on the right side of the shell, wherein the water chamber is divided into a first front water chamber, a second front water chamber, a third front water chamber and a fourth front water chamber from bottom to top through a first front water chamber baffle, a second front water chamber baffle and a third front water chamber, and the four front water chambers are correspondingly provided with a first cold water inlet, a first hot water outlet, asecond cold water inlet and a second hot water outlet. The back water chamber is divided into a first back water chamber and a second back water chamber from bottom to top through a back water chamber baffle. According to different conditions of quality of heat and heating load of different power plants, the condenser with the both heat supply and condensation functions transforms condensers of all condensing units to realize the flexible application; the workload of transforming is less, the primary investment is low, and the switching of combined heat and power and pure condensing power supply can be realized.

Description

technical field [0001] The invention belongs to the field of thermal power plant equipment, and in particular relates to a condenser with both heat supply and condensation functions, which can realize flexible applications, such as peak regulation and heat supply transformation in power plants. Background technique [0002] There are several forms of power generation and heat supply in existing thermal power plants: one is the full condensation power generation type, that is, all the enthalpy drop of the steam turbine is used for power generation, and the condenser vacuum is as high as possible to reduce the back pressure to improve the steam conversion efficiency. The exhausted steam discharged from the steam turbine is completely turned into waste heat. Although the power generation of the whole power plant is large, there is no heat supply component. When heating is required, one is steam extraction heating, because the steam extraction volume is adjustable, and can chang...

Problems solved by technology

[0003] The above forms are single equipment schemes adopted in power plants. The steam extraction type can only realize full condensation and partial heating. There are no functions such as full condensation, multi-channel heating, partial heating and condensation in one device. Realized solutions, and currently there is a lack of technical solutions for fully condensing power plants with basically a small amount of equipment modification and low initial investment
