Ultra-high temperature burner

Abstract

The invention discloses an ultrahigh temperature combustion machine, comprising an injection pipe and a combustion machine body, wherein a nozzle of the combustion machine body is connected with the injection pipe, the combustion machine body is of a dual-sleeve structure composed of an inner sleeve and an outer sleeve, the interior of the inner sleeve is an oxygen-rich primary mixing combustion chamber, and an air preheating and pressurizing cabin is located between the inner sleeve and the outer sleeve. According to the invention, heat out-diffused from the oxygen-rich primary mixing combustion chamber of the inner sleeve is used to preheat air flowing at a high speed in the inner sleeve in advance, which is beneficial for full mixing of air and a fuel, enables heat loss to be reduced and the machine body to be protected, provides pneumatic cooling for the machine body, allows operating temperature at a position of the outer sleeve closest to the injection pipe to have a temperature of only about 150 to 200 DEG C and a position of the outer sleeve close to an air inlet to be in a normal temperature state and enables the service life of the whole machine to be prolonged; the inner sleeve is of a multi-line helical structure, so air enters into the oxygen-rich primary mixing combustion chamber in the form of fine air-flow lines, which is beneficial for full mixing of air and the fuel to form an optimal air-fuel ratio.

Description

technical field [0001] The invention relates to a heating device, in particular to an ultra-high temperature burner. Background technique [0002] The burner is an intelligently controlled thermal energy generator. With the development of industrial modernization and the improvement of people's living standards, the global demand is experiencing an astonishing upward trend, and the development prospects are extremely broad. However, at present, the combustion technology adopted by many production enterprises at home and abroad is relatively common, that is, after the fuel is ignited, it is sent out by the fan in a push shape; even in many oil-fired burners, the state of flying oil will occur during the combustion process; the fuel cannot be fully burned , high energy consumption, and a large amount of smoke and exhaust gas are produced at the same time, which is self-evident to the pollution of the environment.
