Condenser water replenishment system of heating unit

Abstract

The invention relates to the field of heating units, aims to solve the problem that the conventional water replenishment method cannot adapt to different extraction steam flow rates, and provides a condenser water replenishment system of a heating unit, which includes a condenser shell and a condenser throat connected to each other It also includes the basic water replenishment module and the heating water replenishment module; the basic water replenishment module includes the water replenishment module; the heat supply water replenishment module includes multiple heat supply water replenishment sub-modules with different flow rates; There are atomizing nozzles; the atomizing nozzles are arranged at the throat of the condenser; the flow range of each heat supply and water supply sub-module is adapted to the inherent atomization flow characteristics of the atomization nozzle of the heat supply and water supply module; each heat supply and water supply sub-module is It is constructed to be able to switch and adjust the flow, and can be combined freely. The invention has the beneficial effects of being able to adapt to the changing requirements of the heat supply flow rate, and enabling the atomizing nozzle to have a good atomizing effect and a stable oxygen removal effect under various replenishment amounts of water.

Description

technical field [0001] The invention relates to the field of heating units, in particular to a condenser water replenishing system for heating units. Background technique [0002] The chemical water make-up water of the conventional thermal power turbine is discharged into the throat of the condenser, and the water level of the condenser is used to control it. The same method is also used in the heating unit, but the design flow of the make-up water is larger. [0003] However, in actual operation, the flow of extraction steam for heating is constantly changing with the increase or decrease of heat users and the change of heating season. If the conventional water supply method is still adopted, when the extraction flow is small, the The pressure head cannot be guaranteed, which seriously affects the atomization level of the nozzle and the deoxygenation effect of the water replenishment, resulting in a high degree of subcooling and a large oxygen content in the condensed wate...
