Abstract

The invention provides a novel waste heat recovery combined heating and power system. Main system equipment includes a dual-pressure waste heat boiler, a first generating set, a second generating set, a third generating set, a condenser, a condensate pump, an oxygen extractor, a water supply pump and the like. The first generating set is connected with a high-pressure steam pipeline of the dual-pressure waste heat boiler to form a heating and power system. The second generating set is connected with the high-pressure steam pipeline and a low-pressure steam pipeline to form two generating loops. The third generating set is connected with the low-pressure steam pipeline of the dual-pressure waste heat boiler to form a generating loop. The novel waste heat recovery combined heating and power system can be flexibly designed and scheduled to achieve combined heating and power supply according to actual situations and specific needs; for users with highly varying seasonal heating needs or heat loads, steam recovered by the waste heat boiler can be fully utilized, and energy resources can be maximally utilized; the novel waste heat recovery combined heating and power system is simple, reliable and good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of industrial waste heat recovery and utilization, in particular to a novel waste heat recovery combined heat and power system. [0002] Background technique [0003] With the increasing shortage of conventional energy and the increasing requirements for energy conservation and emission reduction, higher requirements are put forward for energy recovery and efficient comprehensive utilization, and production enterprises pay more and more attention to the recovery and utilization of process waste heat and energy, so the cascade distribution of energy and high efficiency Utilization is particularly important. At present, in the utilization of industrial waste heat, waste heat boilers are generally used to recover heat energy. Usually, steam is recovered by dual pressure, and dual pressure is used to generate electricity, and at the same time (or) undertake heat supply. Due to geographical or other reasons, so...
