Moderate and low temperature mixed working medium thermal and electrical combined cycle based on brown cycle

Abstract

The invention relates to a moderate and low temperature mixed working medium thermal and electrical combined cycle based on a brown cycle, which is an integrated cycle system utilizing the characteristics of a capillary pumped loop (CPL) heat pipe, an evaporator, a condenser, a steam channel, a liquid channel, a liquid storage, an isolator and a control system. The liquid contains copper oxide and water nanometer fluid, so that the heat conductivity coefficient of the liquid is increased in the speed of 103 times, the heat transfer coefficient of the heat pipe is increased by 160% to the maximum extent, and the critical heat-flow density is increased by 120%. A turbine power generating system with an injection cycle loop mainly comprises an injector, a pressurizing chamber, a turbine and a loop heat pipe heater. The pressure of hot water increased to 150 DEG C through two-stage pressurization and three-stage pressurization is increased to 3-5 MPa by a mixed steam in the pressurizing chamber in a heat-insulated and speed-reduced way, and the steam enters a gas turbine and adiabatically expands to apply work outwards. The temperature and the pressure of a part of steam meet inlet conditions required by the normal operation of the injector.

Description

[0001] Technical fields: thermal and nuclear power generation, cogeneration of heat and power, distributed cogeneration of heat, power and cooling, coal-based polygeneration technical background: [0002] (I. Introduction: [0003] The direction of energy power system research mainly depends on the trend of world energy development and structural changes and the development of energy science itself. Its research can be divided into three generations: the first generation of research is based on the first law of thermodynamics, and generally obtains higher thermal efficiency by improving cycle thermal parameters and internal efficiency of components; the second generation is characterized by the second law, Focusing on the organic combination of energy grade differences, cascade utilization and different cycles, the total energy system is proposed; the third-generation research highlights the concept of sustainable development, focusing on the combination of total energy syste...

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
