Problems solved by technology

The disadvantages of these three burners are: the temperature of fuel and air is low before starting to burn, the combustion must be carried out under oxygen-rich conditions, the oxygen demand is large, the combustion is unstable, the flame in the furnace has a temperature peak, and there is a flame interface , the furnace temperature difference is large, the average temperature of the furnace is low, the flue gas temperature is high, the thermal efficiency is low, and CO and NO x high content
Insufficient combustion pollutes the environment and wastes energy

Embodiment Construction

[0013] Such as figure 1 , figure 2 As shown, the double-height burner of the present invention includes three parts: an air supply part, a fuel supply part and a vaporization heating combustion part.

[0014] The structure of the fuel supply part wherein is as follows: the end portion of the claw-shaped fuel delivery pipe 8 that opens upward is provided with the aperture 7 that sprays around, and purpose is to make the liquid or gaseous fuel that enters preheating vaporization chamber 5 evenly distribute. The end periphery of the fuel delivery pipe 8 is sealed with a preheating vaporization chamber 5, and the other end of the fuel delivery pipe 8 is combined and then connected to the fuel tank through a control switch 14; Angle is 120 ° of tube bundles, such a structure can make the fuel evenly enter the preheating vaporization chamber 5;

[0015] The structure of the vaporization heating and combustion part is as follows: the upper end of the delivery pipe 11 is connected ...

Abstract

The present invention relates to a double-high combustor, including three portions of air supplying portion, fuel supplying portion and varporization heating and combustion portion. As compared with existent combustor said invention possesses the following advantages: heating air to obtain high-temp. air mixing the high-temp. air with high-temp. gas to make mixed combustion, combustion temp. is high, combustion is stable, combustion is full and high in thermal efficiency, CO and NOx contents are low, its preheating vaporization chamber is placed outside of combustor, it can reduce heat quantity loss, and can increase heating varporization area, and its gas temp. is raised, so that it possesses good service ability.

Description

technical field [0001] The invention relates to a burner, in particular to an environment-friendly and energy-saving burner which uses high-temperature gas and high-temperature air for mixed combustion. Background technique [0002] At present, there are three types of burners on the market: the first is a liquid fuel atomization burner, which burns after the liquid fuel is atomized and mixed with air at normal temperature; the second is a liquid fuel vaporization burner, which is a liquid fuel vaporization Mixed combustion with normal temperature air; the third type is gas fuel burner, normal temperature gas fuel is mixed with normal temperature air for combustion. The disadvantages of these three burners are: the temperature of fuel and air is low before starting to burn, the combustion must be carried out under oxygen-rich conditions, the oxygen demand is large, the combustion is unstable, the flame in the furnace has a temperature peak, and there is a flame interface , ...
