Description
Technical field
The rubbish that big, easy dust deposition is fluctuated the present invention relates to burning city domestic garbage field, especially thermic load is burnt
Burn waste heat boiler.
Background technology
There are following characteristic for refuse incineration exhaust-heating boiler：When thermic load is low or during the non-dust deposition of radiation channel, enters
Hot device flue-gas temperature is relatively low, and it is larger that steam is heated to superheater area needed for rated temperature；When thermic load is high or radiation channel
It is higher into superheater flue-gas temperature during dust deposition, it is smaller that steam is heated to superheater area needed for rated temperature.Due to
Enter the change of stove quantity of refuse, refuse thermal value rises year by year and the factor such as refuse thermal value seasonal variety, cause waste incineration waste heat pot
Stove thermic load is fluctuating in a big way.Domestic waste ash content is high, and the flying dust fusing point that flue gas carries after burning is low, waste incineration
Radiation channel is there are different degrees of dust stratification or coking after waste heat boiler operation a period of time, and when running, the fluctuation of improper or thermic load is big
When, dust deposition phenomenon is especially serious, reduces radiation channel caloric receptivity and causes entry into superheater flue-gas temperature compared with initial operating stage
Rise about 50~120 DEG C.Since thermic load fluctuation is big and the waste heat boiler of the objective reality, at present conventional design of dust deposition phenomenon
Easily there are the easy overtemperature of main steam, water spray is big, high temperature superheater inlet flue gas temperature high corrosion speed is fast, it is specified to be unable to reach for a long time
The series of problems such as vapor (steam) temperature and safe and continuous run time are short.

Mouth header.
Further, six control valves are control valve group I, control valve group II, control valve group III, control valve group respectively
IVth, control valve group V, control valve group VI form.Reversible type refuse incineration exhaust-heating boiler superheater is opened by six valve groups
Close to realize the conversion between water-cooling system and superheating system.Each control valve group is by electric check valve, hand stop valve and stops
Valve group is returned into wherein control valve group I, control valve group II, control valve group III control superheated steam flow, control valve group IV, control
Valve group V, control valve group VI control saturated water and steam water interface flow.To prevent maloperation, control valve group I, control in the system
Valve group II and control valve group III processed, control valve group IV, control valve group V, VI open/close states of control valve group are chain each other.Due to valve
The door actuator response time, all electric check valve out codes postponed to perform for 30 seconds, to ensure heat convection pipe there are deviation
Beam has working medium all the time, prevents dry accident.Each control valve group sets a check-valves to protect electric check valve turning
Hit when changing from vapour or water attack, while effectively avoid steam or the flowing of carbonated drink upstream direction in transfer process.
When being converted to superheating system work, convective heat exchange tube bundles are two-tube circle following current model.Exported from high temperature superheater
The superheated steam of header enters reversible type superheater import header by connecting tube, then in turn through first two columns heat convection
Enter reversible type super-heater exit case after tube bank, reversible type superheater lower header, next two columns convective heat exchange tube bundles, finally
Collection vapour header is entered by connecting tube.Convective heat exchange tube bundles increase superheater area after being converted to superheating system, it is ensured that rubbish is burnt
Waste heat boiler is burnt in the low dust deposition non-with initial operating stage radiation channel of thermic load, and steam is heated to rated temperature.
When being converted to water-cooling system work, convective heat exchange tube bundles intersect flow model for four pipeloops.Drum bottom saturated water warp
Cross downcomer and enter reversible type superheater lower header, subsequently into four row convective heat exchange tube bundles, saturation in convective heat exchange tube bundles
It is transformed into steam water interface after water heat absorption flue gas heat and enters reversible type super-heater exit case and convertible by density contrast
Formula superheater import header, then enters drum by connecting tube.Convective heat exchange tube bundles increase politics and law after being converted to water-cooling system
Protector area, it is ensured that refuse incineration exhaust-heating boiler increases in the high a period of time radiation channel dust deposition with operation of thermic load
Big evaporation protector caloric receptivity, is lowered into high temperature superheater flue-gas temperature, avoids main steam overtemperature and superheater high temperature corrosion.
Apparatus of the present invention can be changed between water-cooling system and superheating system, and it is negative effectively to solve refuse incineration exhaust-heating boiler heat
Lotus fluctuates the big and easy dust deposition problem of radiation channel.Apparatus of the present invention adjust by convective heat exchange tube bundles conversion, optimize pot
Stove evaporating heating surface and overheat heating surface ratio, so that workshop initial investment cost between reducing refuse incineration exhaust-heating boiler and burning
Increase and decrease heating surface area type technological transformation with the later stage is prevented.Apparatus of the present invention conversion can not blowing out carry out, can ensure that waste incineration waste heat
Boiler long-time safe operation.
