Mixed-fuel burning proportion＜5%;
The little negative pressure of anhydration system pressure;
The floor space 800m of system
2About.
As shown in Figure 1, said system also comprises:
In addition, the application of the foregoing description is made a concrete analysis of as follows not influence of fuel-burning power plant operation:
(1) to not influence of boiler combustion
The water ratio of mud is 20～30% after the mummification, is than the loose granule shape, can directly get into power plant's mixed coal, coal mill system, does not therefore need boiler body is transformed.When the mixed-fuel burning proportion of mud and coal hour (requiring less than 5% usually), burning mixed mud is less to the influence of boiler thermal output, and the tail gas quantitative changeization is also not too large, and furnace temperature is not had too much influence.Therefore mixing the burning project at implementation in power plant sludge drying one can not have a negative impact to the normal operation of boiler of power plant.
(2) to not influence of air preheater operation
The high-temperature flue gas (300～350 ℃) that the drying and other treatment system needs extracts before air preheater.Usually when selecting air preheater, can keep 5% surplus.Therefore in order to ensure the works better of boiler air preheater, limit the fume extraction amount usually and be no more than 5% of total exhaust gas volumn.
(3) to the not influence of power-plant flue gas treatment system
When the mixed-fuel burning proportion of mud and coal hour (requiring less than 5% usually),, therefore mix ash content, SO in the burning flue gas because the amount of N that mud is brought into and S is very limited
2Do not have remarkable increase with the concentration of NOx etc., so can the smoke processing system of power plant not had a negative impact.Coal-powder boiler higher furnace temperature (1300 ℃) can effectively be eliminated the Dioxins that produces in the sludge incineration process in addition, avoids the secondary pollution problem.
(4) to the not influence of power station environment health
Usually in the mud heat drying process, can produce more foul gas, can have a negative impact to hygienic condition on every side as not controlling.This mummification technology is that the extracting high-temperature flue gas carries out sludge drying before the air preheater, and the tail gas that moisture eliminator is discharged advances into the smoke processing system of power plant from electric precipitator.Therefore the foul smell of sludge drying generation can obtain partially disposed in smoke processing system.When the mixed-fuel burning proportion of mud and coal hour (requiring less than 5% usually), the drying tail gas amount is no more than 10% of the total exhaust gas volumn of power plant.Flue gas after handling in addition is through the high smoke stack emission of 200m.Therefore under the less situation of mixed-fuel burning proportion, can the environmental health of power plant not had a negative impact.
