Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] figure 1 , the combustion chamber 9 is divided into three areas: evaporation zone 3, mixing zone 5 and combustion zone 8. The fuel is gasified in the evaporation zone 3, which is brought into the evaporation zone 3 by the primary air, and then through a reasonable secondary air organization, the gasified liquid fuel is fully mixed in the mixing zone 5, and mixed The zone 5 is close to the auto-ignition temperature, and by setting the necking plate 7 and the vent hole 6 between the mixing zone 5 and the combustion zone 8, the fuel can achieve homogeneous lean combustion in the combustion zone 8, thereby controlling Nox pollution The generation of things.

[0019] The evaporation zone 3 is near the closed end of the combustion chamber 9 and is mainly the area where the fuel evaporates or gasifies. At the closed end of the combustion chamber 9, t...

Abstract

The invention relates to a vaporizing mixing burning method of liquid fuel and relative burning room, which can solve the problems of present technique that air pollution and partial combustion. Said method comprises: (1) liquid fuel first is heated and vaporized or gasified in the vaporizing section of burning room, to be fed into the mixing section of burning room via the first air; (2), in the mixing section, the combustion air forms the secondary wind to be mixed with the fuel, to reach the self-combustion temperature; (3), the mixed combustible mixed gas is fed into the burning section of burning room, to be uniformly burnt, while the waste gas is discharged.

Description

technical field [0001] The invention belongs to the technical field of combustion, and in particular relates to an evaporation mixed combustion mode of a liquid fuel of a liquid heater and a combustion chamber thereof. Background technique [0002] At present, liquid-type heaters and micro gas turbines have received extensive attention from industries such as automobiles, power and electric power. The market of liquid heater and micro gas turbine has great potential, but its application will depend on the capture and development of a series of key technologies. First of all, it is necessary to develop low NOx emission combustion technology to meet environmental protection requirements, which is a weak technical link at present. From the perspective of combustion phenomena, the combustion of heaters and micro gas turbines is continuous combustion, which is very different from existing combustion technologies such as internal combustion engines and oil-fired boilers. In the ...
