Abstract
The invention aims at providing an asymmetric preheating combustion chamber, which comprises a combustion chamber outer wall, a combustion chamber bottom, a preheating pipe and a fuel inlet wall, wherein the preheating pipe is arranged in the combustion chamber outer wall, the preheating pipe and the fuel inlet wall and the part of the combustion chamber outer wall form a combustion area, the fuel inlet wall, the rest part of the combustion chamber outer wall and the bottom of the combustion chamber form a fuel mixing chamber, an air inlet is arranged in the combustion area part of the combustion chamber outer wall, and a fuel inlet is arranged in the fuel inlet wall.. According to the invention, the asymmetric combustion chamber structure is adopted, air enters the combustion area through a tangential inlet, flame is stabilized through a tangential rotational flow, at the time, a high-temperature area of the flame is positioned around a center shaft. The preheating pipe is arranged on the center shaft of the combustion chamber, thus the initial temperature of the fuel is increased, and the combustion efficiency is improved. Through an asymmetric tangential rotational flow technology and a preheating technology, the purposes of reducing emission and increasing combustion efficiency can be achieved.
Description
Technical field
What the present invention relates to is a kind of gas turbine, specifically the combustion chamber of gas turbine.
Background technology
The energy is the material base of mankind's activity, and the United Nations's climate change conference of holding in Copenhagen in 2009 lets the whole world all recognize, energy problem is most important to environmental protection, and the especially traditional fossil energy industry of energy industry is very big to the influence of environment.Although continuous progress along with energy science and technology; A series of new energy technologies such as solar energy, wind energy, biomass energy obtain fast development; But be that the fossil energy of representative is still the topmost primary energy of the China and even the world today with coal, oil and natural gas up to now.
In order to improve rate of energy, integrated gasification combined cycle for power generation, the living beings gasification, measures such as chemical back heating cracking are used and are given birth to.
Extensive use at present be in the gas turbine of fuel with the natural gas, all be to organize burning basically through the eddy flow that cyclone produces.This is that strong shearing and the effect of entrainmenting can realize turbulent mixing fast between fuel-air-combustion product, reach the purpose of overheavy firing process because swirl flame has had the high temperature recirculation zone of steady combustion effect.Eddy flow through air and fuel in the gas turbine that with the synthesis gas is fuel cooperates organizes burning, and this also is the very selection of reality.So just let fuel carry out smooth combustion, but not necessarily satisfy the requirement of low emission.
Summary of the invention
The object of the present invention is to provide and adopt asymmetric tangential swirl and preheating technology, make the highest flame temperature of combustion chamber reduce, reduce the NOx discharging, improve the fuel inlet temperature, improve a kind of asymmetric preheated burning chamber of the utilization rate of fuel.
The objective of the invention is to realize like this:
A kind of asymmetric preheated burning of the present invention chamber; It is characterized in that: comprise outer wall of combustion chamber, bottom, combustion chamber, economizer bank, fuel inlet wall; Economizer bank is installed in the outer wall of combustion chamber, and economizer bank and fuel inlet wall and partial combustion chamber outer wall constitute the combustion zone, and fuel inlet wall and outer wall of combustion chamber remainder and bottom, combustion chamber constitute the fuel mix chamber; The combustion zone part of outer wall of combustion chamber has air intlet, has fuel inlet on the fuel inlet wall.
The present invention can also comprise:
1, described outer wall of combustion chamber comprises that two cross sections are the semicylinder of semicircle, and the center of circle of the cross section of two semicylinders point-blank and not overlaps.
2, described air intlet has two, lays respectively on the vertical section of two semicylinders.
Advantage of the present invention is: the present invention has adopted asymmetric chamber structure, and air enters into the combustion zone through tangential inlet, comes the retention flame through tangential swirl, and this moment, the high-temperature region of flame was positioned at around the central shaft.Central axis is arranged preheating pipe in the combustion chamber, improves the initial temperature of fuel, improves efficiency of combustion.Can reach the purpose that reduces discharging and heighten efficiency of combustion through asymmetric with two technology of preheating such.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an A-A profile of the present invention.
The specific embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～2, the present invention mainly comprises economizer bank 1, combustion zone 2, fuel inlet 3, fuel mix chamber 4, air intlet 5, chamber wall 6, fuel inlet wall 7, bottom, combustion chamber 8.
Fuel gets into from economizer bank 1, and this fuel can be single gas, the liquid fuel after the evaporation, and synthesis gas (like the chemical back heating cracking gas etc.); Fuel in economizer bank through tube wall and combustion gas carry out heat exchange, improve the temperature of self, reduce the temperature of flame simultaneously, reduce the formation of NOx; Get into fuel mix chamber 4 then, here fuel carries out abundant blending, eliminates the uneven phenomenon of being heated; And the upper wall surface through the fuel mix chamber carries out heat exchange, and the temperature of fuel is improved once more, and at this moment high-temperature fuel is by fuel inlet 3 ejections; After the air of being come in by air intlet 5 contacts, after igniter is lighted, in combustion zone 2, burn; At this moment, high through the fuel temperature of preheating, have the advantage that is prone to light.The characteristics of this combustion chamber are to have adopted preheating and asymmetric techniques, have efficiency of combustion height, the low advantage of discharging.
In asymmetric combustion chamber, adopt the tangential introduction of air mode of entrance, make to produce tangential swirl in the combustion chamber, thus smooth combustion; And fuel carried out preheating, and improve the inlet temperature of fuel, make to reach the effect that improves fuel availability by the fuel easy firing.
The present invention adopts above technical scheme to can be implemented under the situation that does not have cyclone, through the tangential swirl retention flame, and improves the inlet temperature of fuel through the means of preheating, thereby improves efficiency of combustion.
