Britten-steam Rankine-ammonia steam Rankine combined circulation electricity generation device

Abstract

The invention relates to a Britten-steam Rankine-ammonia steam Rankine combined circulation electricity generation device. The exhaust gas of a Britten gas turbine is used as a heat source for steam Rankine-ammonia steam Rankine combined circulation, a steam condenser of the steam Rankine circulation is used as an evaporator of the ammonia steam Rankine circulation, the characteristic that an ammonia steam Rankine system has higher efficiency on the medium-low temperature heat source is utilized, a great amount of latent heat of vaporization released through steam condensation is used for ammonia steam Rankine circulation efficient electricity generation, more than 50 DEG C / ton steam can be additionally recovered only in aspect of utilizing latent heat of vaporization of the steam Rankine circulation steam, meanwhile, the safety problem of the smoke gas afterheat recovery of the ammonia steam Rankine circulation is solved, the exhaust smoke temperature is effectively lowered, and in addition, the low-temperature corrosion of the smoke gas is avoided. The Britten-steam Rankine-ammonia steam Rankine combined circulation electricity generation device can be used for the energy-saving transformation of the existing machine unit, and can also be used for the design and the building of newly built machine units, and the economic, social and environment-protection benefits are obvious.

Description

technical field [0001] The invention relates to a Breton-steam Rankine-ammonia steam Rankine combined cycle power generation device, specifically belonging to the technical field of thermal power plant power devices. Background technique [0002] Gas-steam combined cycle has a series of advantages such as high thermal efficiency, fast start-up speed, good environmental protection conditions, short installation period, low investment cost, etc., coupled with the rapid development of gas turbine technology in recent years, the single unit power of gas turbine is also increasing continuously, combined cycle The research has attracted the attention and implementation of countries all over the world. [0003] The research on combined cycle power generation technology in foreign countries began in the late 1960s. After decades of development, at present, the gas-steam combined cycle power generation technology in many developed countries such as the United States, the United Kingd...

Problems solved by technology

[0008] The Kalina cycle power generation technology mentioned above also has its inherent disadvantages: For example, ammonia is flammable, explosive and toxic. When using the waste heat of flue gas to organize Kalina cycle power generation in the tail flue of boilers or industrial furnaces, it must To consider the leakage caused by dust in the flue gas caused by wear and corrosion of the heat exchanger arranged in the flue, it is necessary to consider the resulting explosion protection and the protection of the environment and working place; the ammonia-water mixture as the working medium Karina cycle, ammonia in ammonia water is a flammable, explosive, toxic medium
