Description
Technical field
This application involves the garbage powers of environment protection field more particularly to superpower heat build-up antiradiation type combustion chamber and very-high performance
Boiler.
Background technique
Burning city domestic garbage be easy thoroughly it is innoxious, can volume reduction 70~80%, loss of weight 50~80%, in certain item
Also its cogeneration or direct industrial application can be realized recycling under part, already by paying attention to extensively both at home and abroad and answer
With.
However, since domestic waste water content is high, generally 40~60%, calorific value is low, generally 3000~
6000kJ/kg, bulk density is small, generally 0.25~0.5t/m3, so the burning grate area needed is 3.5 times of coal-burning boiler
More than, while excess air coefficient is commonly 2.0 or so just can guarantee that incineration firing is abundant, therefore the volume of combustion chamber is big, combustion
Burn exhaust gas volumn causes the volume of boiler system especially huge more, is 3 times of burning boiler or more.The operational efficiency of boiler is very low,
It is usually no more than 75%, investment is especially huge, and the project investment for averagely burning rubbish per ton is 50~750,000 yuans, uses
Service life, other than social enviroment protection benefit, independent economic benefit was not known where to begin less than 30 years.
In addition, due to containing the more ingredient containing chlorine and heavy metal element for being difficult to sort in rubbish, so rubbish is burnt
In the flue gas of burning, there are more sour gas, a certain amount of heavy metal and hypertoxicity pollutant dioxin, give qualified discharge band
Come very big technology and economic pressures, brings certain adjacent wall phenomenon to garbage power enterprise is built.
It researchs and analyses and thinks, since the level of technology is limited, the excess air coefficient of domestic and foreign current standard is generally very big,
The excess air coefficient standard value in China is αk=2.1, it is 150 DEG C by exhaust gas temperature, is equivalent to every burning low level fever
Amount is 1 kilogram of rubbish of 6639kJ/kg, to generate 8.7 cubic metres of exhaust gas volumns for needing to purify, practical online garbage power generation boiler
For qualified discharge, more than this numerical value and stale, this not only needs the air blower and air-introduced machine of super high power, but also makes
The exhaust gas volumn for needing to purify is also very big, keeps garbage power system especially huge, mismatches with its power pole.Exactly this is former
Cause both increases great difficulty to garbage power project investment, the reduction of boiler operatiopn cost and the simplification of flue gas purification system
Degree.

Room outlet 25 enters after-flame chamber inlet 41, and the uncombusted part of rubbish is further from bottom to top in secondary furnace 4 in high-temperature flue gas
Burning, after-flame, simultaneously, when the Leachate site of rubbish is selected by chamber temperature or using the addition for supplementing fuel, from multiple mists
Change Leachate site fore nozzle and multiple atomization Leachate site rear jets spray into secondary furnace, alternately sprays into atomization from these spouts when necessary
Urea or ammonia spirit, the ammonia and nitrogen components contained in Leachate site are conducive to flue-gas denitrification, are the attached of Leachate site of directly burning away the refuse
Add benefit.4 900 ± 100 DEG C of high-temperature flue gas in top of secondary furnace, a part enter high-temperature flue gas injection from secondary furnace first outlet 42
Device 1, and 20 DEG C of air with pressure from dump pit top are mixed into high-temperature low-oxygen combustion air.The big portion of high-temperature low-oxygen combustion air
It is allocated as passing through fire grate, waste layer from reciprocal grate bottom for First air and enters combustion chamber 2, small part is as Secondary Air before multiple
Arch Secondary Air entrance and multiple rear arch Secondary Air entrances enter secondary furnace 4.Most of high-temperature flue gas is from secondary furnace second outlet 43
Enter packet corner portion superheater into water-cooling screen radiation area 5, after being cooled to 600 ± 30 DEG C by preceding water-cooling screen 53 and rear water-cooling screen 54
Area 7, by packet corner portion side fin panel casing 71, packet corner portion rear shed pipe fin panel casing 72, high temperature superheater 74 and low temperature mistake
Hot device 73 is cooled to 350 DEG C and enters economizer unit 9, and the cooling through economizer unit 9 eventually becomes 150 DEG C of discharge boilers and enters
Flue gas purification system.
The application cancel it is expensive can only conventional vapour, gas air preheater by air preheat to 220 DEG C, using height
Warm flue gas ejector 1 makes 20 DEG C with pressure by blower export above dump pit of 1000 DEG C of high-temperature flue gas at the top of secondary furnace
Air ejection, and be mixed into the high-temperature and low-oxygen combustion air that temperature is 300 ± 30 DEG C, oxygen content is 16+2% enter four sides have
The combustion chamber 2 of reflection arch, the excess air coefficient from air blower is less than 1.2 at this time, mass ratio of induced-to-inducing air 0.4, into combustion chamber and
The volume of the combustion air of the high-temperature low-oxygen of secondary furnace is 1.68 times of theoretical combustion air, i.e., nominal excess air coefficient is
1.68, the combustion efficiency with fabulous 3T1E, however secondary furnace exports the exhaust gas volumn in later heating surface flue, i.e., finally
The exhaust gas volumn for needing to purify, exhaust gas volumn when still with blower export excess air coefficient less than 1.2 are identical.
Halve in view of exhaust gas volumn, the noxious pollutant in flue gas has strictly been controlled from source, and the purification of flue gas can become
Simply, qualified discharge can become very easily.Rubbish is in 300 ± 30 DEG C, oxygen content 16+2%, nominal excess air coefficient
It is burned under the conditions of 1.68, eliminates high effect at low cost, can only be by air preheat to 220 DEG C, expensive stainless steel air
The air quantity of preheater, air blower and air-introduced machine reduces nearly half respectively, it is desirable that wind pressure also reduce many, final blast machine and air inducing
The power of machine halves, and the exhaust gas volumn for needing to purify reduces nearly half.Because flue gas peroxide is nitrogen oxides and dioxin pernicious gas
The necessary condition of generation, so the application really effectively controls the generation of nitrogen oxides and dioxin from source, in addition will contain
Have ammonia, the garbage leachate of nitrogen component directly return spray burn be conducive to flue-gas denitrification, so harmful substances in flue gas compares conventional oven
Greatly reduce, greatly simplified in this way, flue gas purification system is inherently derived, to realize garbage power system slimming, investment
Operating cost halves, eventually becomes the independent loops economic entity subsidized without national policy.
Combine detailed description and exemplary example that the application is described in detail above, but these explanations are simultaneously
It should not be understood as the limitation to the application.It will be appreciated by those skilled in the art that without departing from the application spirit and scope,
A variety of equivalent substitution, modification or improvements can be carried out to technical scheme and embodiments thereof, these each fall within the application
In the range of.The protection scope of the application is determined by the appended claims.
