Chemical heat regenerator

Abstract

The invention aims to provide a chemical heat regenerator, which includes an oil-gas mixer, cooperative reforming reactors, electromagnetic valves, and a plasma power supply. Each cooperative reforming reactor includes an outer electrode shell and an inner electrode arranged in the outer electrode shell, and between them a barrier medium a and a barrier medium b are disposed in order. The outer electrode shell includes an outer shell head connection segment, an outer shell middle connection segment and an outer shell bottom connection segment that are connected in order. The outer shell head connection segment is provided with an air inlet, and the outer shell bottom connection segment is provided with an air outlet. Between the barrier medium a and the barrier medium b, a mica sheet is placed on each end of the barrier medium a respectively, and pores are distributed on the mica sheets and are respectively communicated with the air inlets and air outlets. The oil-gas mixer is communicated with the air inlets through the electromagnetic valves, and the plasma power supply is connected to the inner electrodes. With the chemical heat regenerator provided in the invention, the fuel conversion rate can be substantially enhanced, the utilization depth of turbine exhaust waste heat is increased, and the circulating heat efficiency is improved.

Description

technical field [0001] The invention relates to a chemical regenerator of a chemical regenerating cycle gas turbine. Background technique [0002] Chemical regenerative cycle gas turbine (CRGT) is a very promising advanced cycle gas turbine. By adopting fuel steam reforming technology, the exhaust heat of gas turbine is deeply utilized, which greatly improves the thermal efficiency of the gas turbine and is not affected by the pressure ratio of the compressor. A large amount of steam is added to the reformed gas, which increases the heat capacity of the combustion products, reduces the flame peak surface temperature during the combustion process, and effectively reduces the NOx emissions of the gas turbine. [0003] The chemical regenerator is the core component of CRGT, which improves the utilization depth of gas turbine exhaust waste heat by adopting a strong endothermic fuel steam reforming reaction. In order to ensure that chemical regenerative cycle gas turbines can be...
