Embodiment Construction

[0013] In Fig. 1, the existing waste heat power generation system includes a waste heat boiler 1, a steam turbine 2, a generator 5, a condenser 3, a feed water pump 4 and a water supply system 6, and the equipments are connected by pipelines, and the steam turbine 2 drives the generator 5 Power generation, the heat source comes from the waste gas heat source in various industrial processes, and the heat energy in the waste gas heat source is realized through the process of "exhaust gas heat energy----working medium heat energy----mechanical energy----electric energy" through the waste heat boiler The conversion of waste heat resources is also an energy conversion process.

[0014] Specifically, the waste heat boiler 1 heats the waste gas heat energy into water vapor, and the water vapor drives the steam turbine 2 to rotate, and the steam turbine 2 drives the generator to generate electricity. Transported to the waste heat boiler, this is a basic steam power cycle process, and ...

Abstract

A residual heat generation system of signal pressure low parameter backheat comprises residual heat boiler, steam turbine, generator, condenser, water supply pump and water supplementary unit. It is featured as connecting above said equipment and units by pipeline, driving generator to generate power by steam turbine, setting water-supply heating unit between economizer of said boiler and water supply pump, setting main steam pressure of said boiler to be 0.5-2.45Mpa and applying 6-18deg.c as narrow point temperature of said boiler.

Description

technical field [0001] The invention belongs to a waste heat power generation system, in particular to a single-pressure low-parameter regenerative waste heat power generation system. Background technique [0002] Waste heat power generation system is a power generation technology that converts heat energy in exhaust gas into electrical energy, and the corresponding power generation system is waste heat power generation system. The heat source of the waste heat power generation system comes from the waste gas heat source in various industrial processes, and the heat energy in the waste gas heat source is passed through the "exhaust gas heat energy----working medium heat energy----mechanical energy----electric energy" through the waste heat boiler The process realizes the conversion of waste heat resources, which is also an energy conversion process. [0003] At present, the system technology of utilizing waste heat power generation at home and abroad is mainly the conventio...
