Abstract

The invention discloses a novel condensate system provided with a weak water flow steam seal heater. The novel condensate system comprises a condenser. The condenser is connected with the input end of a deaerator water level control valve through a condensate pump. The first output end of the deaerator water level control valve is connected with the input end of a condensate polishing device. The second output end of the deaerator water level control valve is connected with a recycling port of the condenser through a condensate recycling control valve. The first output end of the condensate polishing device is connected with the input end of a third low pressure heater through a first low pressure heater and a second low pressure heater. The second output end of the condensate polishing device is connected with the input end of the third low pressure heater through a steam seal heater cooling water control valve and the steam seal heater. The novel condensate system can solve the problems of large vibration of the condensate recycling control valve and a pipeline thereof, large vibration of the deaerator water level control valve and a condensate pipeline, large noise of the condensate system and the like, unit thermal losses can be lowered, and the lift of the condensate pump is decreased by 5m H2O at least.

Description

technical field [0001] The invention relates to a steam-water system of a condensed water system of a steam turbine generator set, more specifically, it is a condensed water system equipped with a small water flow seal heater. Background technique [0002] The condensate system of the turbogenerator has the following problems: [0003] Vibration of condensate recirculation pipes: In thermal power plants, regardless of unit capacity and parameters, vibration of condensate recirculation pipes is a common phenomenon. Condensate water recirculation flow is the greater of the allowable minimum water flow between the condensate pump and the seal heater. Its purpose is to ensure that the amount of condensed water passing through the condensate pump is not less than the minimum water flow allowed during the start-stop process and low-load operation of the unit, so as to prevent the condensate pump from overheating and cavitation; to ensure that the amount of condensed water passing...
