Abstract

The utility model relates to a sectional combustion apparatus which is composed of a vaporizer of the front section and a main combustion chamber of the back section. The utility model is characterized in that the lower part of a front wall of the vaporizer is an inward inclined surface. The upper part of the vaporizer is provided with a gas passage which is connected with the upper air storage chamber of the gas passage. The air storage chamber is communicated with the main combustion chamber via a gas outlet and a gas passage in turn. A secondary tuyere is arranged on the lower part of the furnace wall which is between the vaporizer and the main combustion chamber. The lower part of a back wall of the vaporizer is provided with a plurality of sprayed burning openings which are communicated with the lower part of the main combustion chamber. The sectional combustion apparatus has the function of enlarging the area of aerification and accelerating the volatilization to convert the coal into the gas, which avoids the upper part of the vaporizer catching fire by the reflected hate of the main combustion chamber and makes the vaporizer be in a state of low temperature. The sectional combustion apparatus facilitates the gas and the coal coke which is pushed on the fire grate of the main combustion chamber to burn out at high temperature. The various environmental indexes are all coincide with the criterion of GB2001. The dust emission is 74 mg/m <3> and the Ringelmann flue-gas blackness is smaller than 1 degree. The discharge capacity of the SO2 is 520 mg/m3. The sectional combustion apparatus can save the coal by 10 to 15% and the heat exchange efficiency is at least 78%.

Description

Novel sectional combustion device
Technical field
The utility model relates to the coal gasification combustion device, relates in particular to the novel sectional combustion device of a kind of fire coal.
Background technology
Coal-burning installation, especially coal-burning boiler have become one of primary pollution source of China's atmosphere, dust in flue gas, black smoke, NOx and SO 2Gas etc. are important pollutants.Restructure the use of energy, using clean energy resourcies such as oil, electricity, gas, solar energy is the fundamental way that addresses the above problem.Right face coal in China is still main energy sources, expects 2010, will account for 70% of China's total energy.Therefore, research and develop the clean combustion technology, become the important topic of numerous scientific and technical personnel's common concern.
Existing gas boiler mainly contains coal-fired steam stove and heat exchanger is formed.Its coal-fired steam stove mainly comprises three ones of gasification, burning and heat exchange.The volatile matter that coal is separated out in burning has restrictive function to the burning of coal tar, makes solid carbon burn numerous and diverseization, difficultyization.Secondary reaction, i.e. CO and CO in the oxidation of solid fuels reaction 2Generation, and the oxidation of CO and CO 2Reduction reaction, all be unfavorable for solid carbon and natural minerals burning of coal.
The designer explores repeatedly by up to a hundred experimental studies, serious analysis, and constantly demonstration works out a kind of novel sectional combustion device.
The utility model content
The purpose of this utility model is to solve the problem that there is atmosphere pollution in prior art, and a kind of novel sectional combustion device is provided, and makes the coal clean combustion, meets the pertinent regulations of country to environmental protection.
The purpose of this utility model is to be achieved by following technical solution:
A kind of novel sectional combustion device is made up of the vaporizer of leading portion and the main chamber of back segment, it is characterized in that:
(1) the front wall bottom of described vaporizer is intilted inclined-plane;
(2) vaporizer top is provided with gas passage near combustion chamber one side; This passage links to each other with the air storage chamber that its top is provided with;
(3) gas exit that is provided with by the furnace wall upside that is located between vaporizer and the back segment main chamber of said air storage chamber links to each other with the gas passage that is in the main chamber inboard; This gas passage links to each other with main chamber.
(4) the furnace wall bottom between vaporizer and main chamber is provided with overfiren air port.
Above-mentioned novel sectional combustion device is provided with a plurality of spray combustion mouths in its described vaporizer Hou Qiang bottom, and this spray combustion mouth links to each other with the main chamber bottom.
The utility model compared with prior art has following advantage:
(a) the vaporizer front wall bottom of leading portion is intilted inclined-plane, has increased draught area, shortens coke pushing mechanism stroke, and pneumatization is enlarged, and volatile matter is separated out rapidly become coal gas, and improve its quality;
(b) gas passage, the air storage chamber that are provided with successively of described vaporizer top; This air storage chamber is communicated with the main chamber bottom by gas exit, gas passage again.This structure, one can reduce the reverberation of back segment main chamber to the leading portion vaporizer, avoids the naked light burning of vaporizer top, makes vaporizer be in reduction and destructive distillation state under the low temperature, thereby guarantees gas quality, prevents to produce CO 2, NO xDeng; To the high coal charge of sulfur content, can add desulfurizing agent CaCO 3Make SO 2Become CaSO 4Two because do not have furnace wall between main chamber and the heat-transfer surface thereafter, prevents hot flue gas short circuit, heat exchange efficiency 〉=78%.
(c) vaporizer Hou Qiang bottom (being plenum area one side lower part) is provided with many spray combustion mouths, makes coal gas directly spray into combustion chambers burn.And be beneficial in the coal volatile matter and separate out fast, change coal gas rapidly into, release on the fire grate of bottom, combustion chamber, after high temperature burns together, prevent that black smoke from producing, economize on coal the raising heat exchange efficiency at main chamber and the coal that will separate out 60~90% volatile matters with coke pushing mechanism.
(d) owing to adopt aforesaid technical scheme, the utility model environmental index meets GB2001 (II period class one zone concentration of emission limit value) standard-required:
Project and unit The utility model The GB2001 standard
Smoke dust discharge concentration mg/m3 blackness of exhaustion (lingemann grade) SO2 concentration of emission mg/m3 74 <1 520 ≤80 <1 ≤900
