Description

Energy carrying and same combined cycle power device

Technical field:

the invention belongs to the technical field of thermodynamics and thermal dynamics.

The background technology is as follows:

power and electricity are two basic and important demands in human life and production; the conversion of thermal energy from source energy into mechanical energy is the most fundamental requirement with simple and efficient technical measures-for this purpose, the skilled person is constantly striving.

The gas-steam combined cycle power device is a main means for obtaining power by utilizing high-temperature heat load formed by burning high-grade high-quality fuel. In order to improve the power application value of high-grade high-quality fuel, the temperature of fuel gas formed by burning the fuel should be increased as much as possible, and the temperature and the quantity of heat emission load of the gas turbine device should be reduced. However, the higher the initial temperature of the gas, the higher the temperature of the gas turbine exhaust gas increases, and the heat transfer temperature difference loss between the upper and lower cycles in the gas-steam combined cycle system increases; therefore, advanced technical approaches are needed to reduce the irreversible loss of temperature differentials in high grade, premium fuel power applications.

After extensive analysis of conventional gas-steam power plants, it was found that it was deficient: due to reasons such as limited working principles or material properties or equipment manufacturing level, great irreversible temperature difference loss exists in the combustion process of forming a high-temperature heat source by high-grade high-quality fuel, which leads to quality loss in fuel utilization, and the like, which provides opportunities for high-value utilization of low-grade fuel.

The invention provides an energy carrying and combined cycle power device which is reasonable in flow, simple in structure, capable of obviously reducing irreversible temperature difference loss of heat load transfer between upper and lower cycles and realizing efficient power application of high-grade fuel, and provides a basic principle of simply, actively, safely and efficiently utilizing energy to obtain power.
