Abstract

The invention discloses a double-unit regenerative drainage system based on a small bypass of a high-pressure heater, and belongs to the field of drainage systems. According to the double-unit regenerative drainage system based on the high-pressure heater small bypass, an override drainage pipeline is additionally arranged between a drainage pipeline between any two high-pressure heaters and a deaerator on a traditional double-unit regenerative drainage system. The invention aims to solve the problem of system instability caused by faults of part of high-pressure heaters possibly occurring inthe working process of the traditional double-unit regenerative drainage system. And when part of the high-pressure heaters exit, the drained water of the rest high-pressure heaters can be conveyed tothe deaerator through the override drainage pipeline, and more energy is saved compared with a system without adding override drainage.

Description

technical field [0001] The invention relates to the field of hydrophobic systems, in particular to a dual-machine heat recovery hydrophobic system. Background technique [0002] With the continuous improvement of high-temperature performance of materials, the steam parameters of coal-fired power generation units are continuously improved to obtain higher cycle efficiency, further reduce the coal consumption of the unit, and reduce the emission of greenhouse gases and other pollutants. Improving steam parameters is one of the most direct ways to improve cycle efficiency of power generation system. However, with the increase of steam parameters, the degree of superheat of regenerative extraction steam increases, and the irreversible loss of heat exchange on the steam side and water side of the regenerative heater increases, which reduces the benefits brought by the increase of steam parameters. The higher the steam parameters, the A contradiction becomes more prominent. [0...
