Abstract

The invention discloses a condensed water combined cycle system and method for improving the cold reheat steam supply capacity of a boiler. The system comprises steam pipeline isolation valves, a heatrecycling heat exchanger, a flow adjusting pore plate, a water inlet isolation valve, a water outlet isolation valve, a bypass isolation valve, a water-water heat exchanger and a circulating pump. Cold reheat steam enters the heat recycling heat exchanger through a steam pipeline, the cold reheat steam is mixed with original steam through a steam return pipeline after being subjected to heat exchange and cooling, the flow adjusting pore plate is newly arranged on the cold reheat steam pipeline for balancing the steam flow, and closed circulating water absorbs heat in the heat recycling deviceand is conveyed into the water-water heat exchanger through the circulating pump. Condensed water at an outlet of a shaft seal heater enters the water-water heat exchanger after passing through the water inlet isolation valve, by means of the system, the cold reheat industrial steam supply capacity of the boiler can be effectively improved, the overtemperature risk of a boiler reheater can be reduced, meanwhile, online operation and shutdown can be realized, in addition, the cold reheat steam supply flow of a unit can be effectively promoted, and therefore, the economical efficiency of the unit is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of energy comprehensive utilization, and relates to a condensed water combined cycle system and method for improving the cold resteam supply capacity of a boiler. 【Background technique】 [0002] External industrial steam supply can effectively reduce the energy consumption index of thermal power generating units, and it is also one of the important profit directions of generating units. On the basis of meeting the steam parameter requirements of industrial steam supply users, using lower-quality steam as much as possible is conducive to the economical operation of the unit. Therefore, increasing the industrial steam supply volume and reducing the steam supply parameters as much as possible is the direction to improve the industrial steam supply economy of the unit. [0003] At present, most industrial steam supply units use cold resteam as the steam source, but if more cold resteam is extracted, the boile...
