Britten-steam Rankine-ammonia vapor Rankine combined cycle power generation device

Abstract

The invention relates to a Britten-steam Rankine-ammonia vapor Rankine combined cycle power generation device. Exhaust of a gas turbine generator unit serves as heat sources of a steam Rankine cycle, a condenser in the steam Rankine cycle serves as an evaporator of a low temperature end Kalina cycle, a positive pressure operating method is adopted by the condenser, latent heat of vaporization of high temperature end steam is effectively recycled for generating electricity, and therefore the Britten, the steam Rankine and the Kalina cycle are compounded together to form an enforceable combined cycle device. A method of indirect heat transfer between ammonia water mixture and exhaust gas is adopted, and therefore the problem of safe operation of a Kalina cycle unit is solved. Compared with traditional combined cycle power generation, the pollution produced in the process of generating of the combined cycle power generation device is reduced by more than 70%. The Britten-steam Rankine-ammonia vapor Rankine combined cycle power generation device not only can be used for energy conservation improvement on an existing machine unit, but also can be used for designing and building a newly built machine unit. The Britten-steam Rankine-ammonia vapor Rankine combined cycle power generation device is especially suitable for new construction, extending construction and reconstruction of a power unit in water-deficient areas, power shortage areas and other areas, and therefore the Britten-steam Rankine-ammonia vapor Rankine combined cycle power generation device has remarkable economic, social and environmental protection benefits.

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...

AI Technical Summary

Problems solved by technology

[0007] 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
