A Turbine Power Generation System with an Ejector Booster Circulation Loop

Abstract

A turbine power generation system with an injection pressurization cycle loop, the main equipment includes an ejector, a booster chamber, a turbine and a loop heat pipe heater, and it is characterized in that: the steam drawn by the turbine is connected in parallel with the waste heat gas As the main steam of the injection pressurization cycle, it is introduced into the nozzle of the ejector for adiabatic expansion, and the generated high-speed airflow will introduce the hot water heated to 90°C into the mixing chamber for mixing, and the mixed steam will increase in adiabatic deceleration in the pressurization chamber. After two-stage or three-stage pressurization, hot water at 150°C is formed and the pressure increases to 3-5MPa, and then enters into a hot water generator for power generation; after hot water power generation, 20°C water is obtained, which passes through the second circulation pump to The absorption heat pump absorbs the heat released by the steam discharged from the exhaust system, and then enters the loop heat pipe heater for secondary heating to 90°C to form the introduced hot water at 90°C. The invention solves the key technical problem of recovering and reusing condensation waste heat, enables efficient utilization of condensation heat of circulating cooling water in power plants, and accelerates the construction of environmentally friendly and clean power sources.

Description

technical field [0001] The invention relates to the technical field of thermal and nuclear power generation, cogeneration of heat and power and distributed coal-based polygeneration of combined heating, power and cooling. Background technique [0002] (I. Introduction [0003] Over the past 100 years, engineering thermodynamics has penetrated into various disciplines and technical fields and formed many new subdisciplines. However, its main research objects are still the law and method of converting thermal energy into mechanical energy and the way to make the heat engine convert heat energy into work more effectively, and the main fields involved are still energy and power. Therefore, the thermodynamic cycle used to realize the closed process of thermal energy and mechanical energy conversion has always been the focus of engineering thermodynamics research, especially the research on new thermodynamic cycles and corresponding new working fluids has become an eternal resear...

Problems solved by technology

However, conventional ejector pressurization still cannot meet the requirements of various fields, such as the development of some important military equipment, the recovery of a large amount of crude oil gas in oil fields (light hydrocarbon recovery), etc., the existing ejector technology should be applied to In these areas, there are two fatal deficiencies: one is that the pressure loss at the inlet and outlet of the system is too large, which cannot meet special needs; the other is that the multi-stage system must lead part of the medium from the inter-stage, which does not meet the requirements
