Problems solved by technology

But because this invention is mainly used for research experiments, in order not to change the structure of the porous medium layer inside the burner, it is selected to use electric spark ignition at the outlet of the combustion chamber. This design is not conducive to the application on the Stirling machine, and makes the burner Ignition time greatly increased

Abstract

The invention relates to a combustion heating system for a Stirling engine. The combustion heating system for the Stirling engine is composed of a straight-shaped gradient lapped type porous medium combustor and a fill type porous medium combustor, which are arranged up and down, wherein the straight-shaped gradient lapped type porous medium combustor comprises a shell, a fuel gas inlet, a pre-mixing chamber, an axial thermal insulating layer, a flame igniter leading wire protective tube, an igniter, a gradient ceramic porous medium layer and a catalyst layer, wherein the fuel gas inlet, the pre-mixing chamber, the axial thermal insulating layer, the flame igniter leading wire protective tube, the igniter, the gradient ceramic porous medium layer and the catalyst layer are arranged in the shell in sequence form top to bottom, the fill type porous medium combustor comprises an external insulating layer, a metal net cylinder arranged in the insulating layer and heating tubes arranged in the metal net cylinder in a central symmetry mode, and the gaps of the heating tubes are filled with metal wires. The combustion heating system for the Stirling engine has the advantages of being stable in combustion, high in combustion efficiency, good in heat transfer performance, good in heat storage performance, stable in working, wide in load regulation range, easy to regulate and less in pollutant discharge, and the effect on improving the fuel gas type Stirling engine working efficiency is remarkable.

Description

technical field [0001] The invention belongs to a combustion and heat exchange device, in particular to a combustion heating system of a Stirling engine. Background technique [0002] The Stirling engine is a closed external combustion engine, which has the advantages of wide fuel sources, high thermal efficiency, less exhaust pollution, good operating characteristics, low noise, etc., and is widely used in the fields of distributed energy, clean gas power generation and solar power generation It has important applications and has attracted more and more attention. [0003] The external combustion system is an important part of the Stirling engine. Its main function is to convert the chemical energy of the fuel into thermal energy through a reasonable and efficient organization of combustion and heat exchange, and transfer it to the heater through the heat exchanger, and then the heater The heat energy is transferred to the working medium in the machine through heat exchang...
