Environment-friendly and energy-saving as well as low-temperature and low-nitrogen combustion system

Abstract

The invention provides an environment-friendly and energy-saving as well as low-temperature and low-nitrogen combustion system. For the environment-friendly and energy-saving as well as low-temperature and low-nitrogen combustion system, noise of the system is effectively reduced by adopting a suspension system, so that the system has a prominent mute effect, and meanwhile, a mute power supply canadapt to different placement modes by adopting a suspension structure, so that the reliability and the applicability of the system are enhanced; mechanical energy in the form of oscillation waves isamplified in a multi-stage mode by coupling with multiple stages of thermo-acoustic units, so that the electrical output capacity of a thermo-acoustic Stirling generator is improved, the diameters andlengths of heat exchangers and heat regenerators of the thermo-acoustic Stirling generator do not need to be increased, the thermo-acoustic Stirling generators with different output powers can adoptthe elements such as the heat exchangers and the heat regenerators with the same specification, so that the application range of the elements such as the heat exchangers and the heat regenerators is enlarged, meanwhile, the power generation efficiency is high, and the noise pollution is small; with the system, energy can be effectively saved, the biomass gas conversion rate can be improved, and the conversion rate can reach 70-80%; and the combustion is sufficient, Nox emission can be effectively reduced, and the Nox emission is enabled to be below the national standard.

Description

technical field [0001] The invention belongs to the technical field of combustion devices, and in particular relates to an environment-friendly, energy-saving, low-temperature, low-nitrogen combustion system. Background technique [0002] Due to the reality of my country's coal-rich, oil-poor, and gas-deficient national conditions, the burning of coal will continue for a long time. Under the circumstances of today's strict environmental protection technical indicators, how to achieve the same level of combustion and emission of coal as close to the effect of natural gas combustion and emission. This will be an urgent problem to be solved for combustion technical workers and environmental protection technical workers. [0003] Fossil fuels are becoming increasingly scarce, and the environmental problems caused by them are becoming more and more severe. As one of the alternative energy sources, bioenergy has been paid more and more attention. Biomass energy has unique advant...

Problems solved by technology

As the required power generation increases, the heat exchanger and regenerator of the Stirling engine need to increase in diameter and length, or use multiple generators to provide the required power, which not only affects the heat exchanger and regenerator. The applicability of components such as heaters, and the installation space of the generator is increased, which increases the noise pollution when the generator is working
