Jet and oxygen-enriched combustion method for gas fuel and burner therefor

Abstract

The invention can utilize the pressure and ejection characters of gas fuel, and the burning energy to arrange the nozzle, ejector and ejection pipe in one axes. The ends of nozzle and the ejection pipe are fixed, while the ejector can axially move in middle stroke. The invention discloses a gas fuel ejection rich-oxygen burner for using ejection rich-oxygen burning method, to combine the nozzle, ejector, and ejection pipe burning room into one ejection rich-oxygen burner. The nozzle is designed as micro-ejection pipe; the ejector is designed as high-efficiency mixed non-stepped speed changer; the ejection pipe burning room has a multifunctional device, while they individually form the lower, middle, and higher temperature burning section. The invention can realize the fire temperature control of fire outlet and transforming the layer burning into whorl burning, which has 100% improved heat efficiency and reduced burning cost than traditional burning method.

Description

(1) Technical field: [0001] The invention relates to a new combustion method of jet technology in the gas fuel field, which is specially named jet oxygen-enriched combustion method, and the invention will also disclose a gas fuel jet oxygen-enriched burner for realizing the method. (two) background technology: [0002] Gas fuel and oxygen can be ignited and burned only after they are mixed in a certain ratio. The supply of oxygen includes oxygen in the air and specially made high-pressure pure oxygen. There are usually two methods of gas fuel combustion. One is the mixed combustion method, which uses the pressure of the gas fuel to mix with air first and then burns. Combustion at high temperature, can not reach the proper temperature, resulting in waste of energy. The second is the mechanical mixed combustion method, that is, the high-pressure airflow is extruded by the air compressor or the high-pressure oxygen airflow is sucked into the low-pressure gas-fuel airflow for m...

Problems solved by technology

There are usually two methods of gas fuel combustion. One is the mixed combustion method, which uses the pressure of the gas fuel to mix with air first and then burns. Combustion at high temperature, can not reach the proper temperature, resulting in waste of energy

The second is the mechanical mixed combustion method, that is, the high-pressure airflow is extruded by the air compressor or the high-pressure oxygen airflow is sucked into the low-pressure gas-fuel airflow for mixed combustion. This combustion method can organize high-temperature combustion, but increases the combustion cost.
