Description
Technical field
The present invention relates to field of boilers, a kind of straw and domestic garbage mixing are burnt and produce steam for steam supply, the boiler of generating.
Background technology
Straw refers to remaining stem and leaf part after the crop maturity threshings such as Oryza sativa L., Semen Tritici aestivi, Semen Maydis.Due to coal, electricity, the commonly using of gas, the demand of straw is reduced by rural area, a large amount of straws be processed into for severe social problem, although law bans, but a lot of local peasants are still at field crop straw burning, cause the serious consequence such as air pollution, fire, and the handling problems of straw becomes increasingly conspicuous.
If using burning as boiler oil, feeding boiler and domestic garbage mixing after straw break process, utilize the heat generation steam burned to be used for steam supply and generating, the most not only can turn waste into wealth, save the energy, protect environment；Can there be again good social benefit and considerable economic benefit.For straw and the fuel characteristic of house refuse; completely newly develop the boiler of First straw and domestic garbage mixing burning; straw after break process is delivered to boiler as fuel; mixed combustion is carried out together with house refuse; the active combustion of straw and house refuse is promoted with this; guaranteeing that mixed fuel firing is abundant, the thermal efficiency is high, and boiler operatiopn is stable.
Summary of the invention
It is an object of the invention to provide the boiler of a kind of straw and domestic garbage mixing burning.
Realize above-mentioned purpose, the present invention adopts the following technical scheme that the boiler of a kind of straw and domestic garbage mixing burning, it uses half outdoor layout, include steelframe, awning, furnace chamber, charging gear, fire grate and slag tap and ash discharge equipment, it is characterized in that: described furnace chamber is installed on steelframe, awning is directly supported on steelframe top board, fire grate is arranged in below furnace chamber, slag tap and ash discharge equipment is installed in fire grate bottom, furnace chamber is by burner hearth, burning chamber and three flues composition, connection flue and back-end ductwork are set after described furnace chamber, and furnace chamber, connect flue and back-end ductwork in " Jiong " type.Charging gear is arranged in described furnace chamber front portion；Described back-end ductwork import department installing bypass flue；Exit is provided with flue gas recirculation pipeline.
Further, it is provided with smoke air preheater, high temperature superheater, medium temperature overheater and low temperature superheater in described three flues, economizer is arranged in described back-end ductwork, described lower furnace portion, fire grate are provided above face arch and rear arch, and at burner hearth front wall and forward and backward arch, distinguish arranging multiplayer secondary wind, wherein, front upper secondary wind is arranged on burner hearth front wall, and remaining secondary wind is arranged at forward and backward arch.
Further, described smoke air preheater uses the material of 06Cr25Ni20, and high temperature superheater piping uses the micro-melting welding of low temperature of corrosion and wear.
Further, in described three flues, being laid with long telescopic steam sootblower at smoke air preheater, high, medium and low temperature superheater, soot blowing platform utilizes the connecting platform between two stoves.
By using such scheme, the invention have the advantages that
1, boiler uses half outdoor layout, and awning is directly supported on steelframe top board, can be greatly saved space, saves construction investment.
2, straw and house refuse together enter fire grate by charging gear, and by high temperature incineration, harmful substance obtains sufficient oxidation Decomposition, reach innoxious, minimizing, the target of resource.
3, for fuel characteristic and house refuse low heat value, high moisture content, the fuel characteristic of ash-rich of straw, straw is blended in the rubbish bed of material, take the lead in being dried under the radiation of red-hot flue gas, catch fire, burn, incineration temperature in burner hearth can be effectively improved, guarantee, when ambient temperature is relatively low and refuse thermal value is relatively low in the winter time, comparatively fast to reach steady working condition.
4, fuel combination burns on fire grate, and the flue gas of generation flows through burner hearth, burning chamber, three flues successively, connects flue and back-end ductwork.Flue gas flow is long, can sufficiently cool flue gas, prevent because of coking affect boiler heat absorption.And, smoke air preheater spy uses the material of 06Cr25Ni20 heat-resistance stainless steel, and high temperature superheater piping uses the micro-melting welding of low temperature of corrosion and wear, substantially increases service life, can effectively guarantee boiler operation long-term, safe and reliable.
5, for there being a certain amount of fly ash particle in fuel combination, being disposed with multilamellar secondary wind at burner hearth front wall and forward and backward arch, wherein front upper secondary wind is arranged on burner hearth front wall, and remaining secondary wind is arranged at forward and backward arch.Make full use of high speed secondary wind jet leader tape and push the effect of flue gas, strengthen the disturbance of flue gas, cause flue-gas swirl, extend flue gas stroke in stove, improve the degree of filling of gas stream in the stove, fuel combination is made to be sufficiently mixed with air, burn completely, burn, it is ensured that in burner hearth, fly ash combustible material reduces, and the oxygen required for aftercombustion.And, the fuel combination for different ratio can be realized, the corresponding secondary wind that adjusts is arranged and air quantity, it is ensured that meet the demand of the various different combustion conditions of clean burn rubbish or straw and rubbish mixed combustion.
6, smoke air preheater, sectionalized superheater, economizer are in-line arrangement, are difficult to dust stratification.
7, in three flues, at smoke air preheater, high, medium and low temperature superheater, all it is disposed with long telescopic steam sootblower, can effectively remove dust stratification, it is ensured that safe operation of the boiler.Soot blowing platform utilizes the connecting platform between two stoves, can effectively save hall space, reduces civil engineering cost.
8, back-end ductwork import department arranges bypass flue, can effectively regulate exhaust gas temperature, is allowed to be in the temperature of applicable environmental protection needs.
9, back-end ductwork exit is provided with flue gas recirculation pipeline, by the flue gas at extraction part boiler export as secondary wind, it is possible to decrease the oxygen concentration in burner hearth, thus reduces the growing amount of NOx, it is ensured that effectively reduce the concentration of emission of nitrogen oxides at boiler export.
