Description
Technical field
The utility model belongs to thermal power generating technology field, especially relates to a kind of comprehensive generating system of mixed firinor fuel burning.
Background technology
According to《China Statistical Yearbook 2014》, China's biomass energy is at present mainly based on agriculture and forestry organic waste material, agriculture waste
If owner's agricultural crop straw.Agricultural crop straw theoretical resources amount is about 8.7 hundred million tons, and equivalent standard coal is about 4.4 hundred million tons, main
It is distributed in 13 major grain producing areas such as the North China Plain, middle and lower reach of Yangtze River Plain, Northeast plain.For the stalk of recycling
Amount is about 400,000,000 tons annual.National bio-energy industry scale steady-state growth, the grid-connected installed capacity of biomass in 2014 are more than 9,480,000
Kilowatt.
The grid-connected installed capacity of China's biomass power generation of the end of the year 2015 is up to 10,310,000 kilowatts, wherein agricultural-forestry biomass direct combustion power generation
It installs 5,300,000 kilowatts, garbage power accounts for 4,680,000 kilowatts, and the two accounts for 97% or more.
Agricultural-forestry biomass direct combustion power generation project is due to by raw material supply capacity and price limit, agricultural-forestry biomass direct combustion power generation
The overall profitability of project weakens, and grid-connected installed capacity growth rate is slowed down.The national grid-connected hair of forest and agricultural biomass direct combustion
Electric installed capacity and distribution are as follows：East China is maximum, installs 200.7 ten thousand kilowatts, accounts for 40%.Biomass Gasification ＆ Power Generation is not yet advised
Modelling is promoted.
Current biomass power plant single-machine capacity is mostly in 12MW between 30MW, and parameter is based on medium temperature and medium pressure.By parameter compared with
Lower limit, generating efficiency are relatively low.According to statistics, 31% or so, boiler efficiency exists biomass electric power plant Steam Turbine efficiency substantially
Between 83%~89%.
According to indexs such as the biomass direct-fired boiler of power plant efficiency of mainstream, turbine heat rates, the biology currently to put into operation is upright
Power plants generating electricity efficiency is fired between 25% to 29%.In addition, biomass direct-fired power plant there is also asking for biomass shortage sometimes
Topic, at this moment would have to shut down, and power generation is caused to implement idle the problem of wasting.
China's domestic waste total amount is big, and remains higher speedup.According to the data of State Statistics Bureau, 2014
The national house refuse amount of clearing has reached 1.786 hundred million tons.Domestic waste complicated component, containing a variety of toxic, harmful, difficult to degrade
Ingredient would seriously pollute the environment if domestic waste effectively not being handled and being disposed, influence the body of people
Health.Therefore, the processing of domestic waste and recycling, it has also become one of major fields of environmental protection
Minimizing, innoxious and recycling demand for domestic waste have the pretreatments such as broken, compacting, sorting
The disposal technologies such as technology, and landfill, compost, anaerobic fermentation, burning and pyrolysis.Year ends 2014, China's house refuse sanitary landfills
604, harmless treatment factory, 10744.3 ten thousand tons of house refuse sanitary landfills harmless treatment amount；Consumer waste incineration is innoxious
Treatment plant 188,5329.9 ten thousand tons of consumer waste incineration harmless treatment amount.As it can be seen that China landfill and burning be two kinds most
Main Disposal of Domestic technology, and the ratio filled at this stage is also significantly higher than burning.The application of consumer waste filling and embedding is gone through
History is long, technology maturation, but the degree being reduced is low, and land occupation area is big, and site selection of landfill is increasingly difficult.Incineration technology it is excellent
Point is that volume reduction, decrement degree are high, it is innoxious thoroughly, the thermal energy contained in rubbish can be recycled, for producing steam and hair
Electricity realizes recycling.Therefore, the application of Consideration of MSW Incineration Technology at home is increasing.Currently, consumer waste incineration
Mainstream equipment be two kinds of grate furnace and fluidized bed incinerator.Both equipment are adapted to that MSW heating value is low, ingredient is multiple
Miscellaneous feature, but incineration temperature wants much lower compared to burners such as generating plant pulverized coal boilers in stove, the parameter of produced steam
It is relatively low with generating efficiency.
There is a large amount of generating plant pulverized coal boiler in China.Development relies on the coal and house refuse coupled electricity-generation skill of generating plant pulverized coal boiler
It is excellent to give full play to the technology that high capacity high parameter thermal power plant ignition temperature is high, pollutants removal rate is high, generating efficiency is high for art
Gesture, for promoting, domestic garbage resource utilizes and environmental protection has positive effect.
2015 end of the years, 14028 ten thousand stere of National urban sewage treatment plant daily handling ability, year sewage disposal total amount
428.8 billion cubic meter.Sludge yield and the height of sewage treatment process and standard have relationship, account for about the 0.3%- of processing water
0.5% (in terms of moisture content 97%), the then sludge that sewage disposal process in 2015 generates reach hundred million tons of 1.29-2.14.Contain in sludge
There are plurality of heavy metal, pathogen and toxic organic compound difficult to degrade, it can also emitting offensive odor.If do not handled effectively sludge
And disposition, it would seriously pollute the environment, influence the health of people.Therefore, the processing of sludge and recycling, it has also become ring
One of the major fields of border protection.
Sludge drying-incineration technology is quickly grown in recent years.Since the sludge of sewage treatment plant's generation is after mechanical dehydration
Still there is very high moisture content, calorific value is very low, after usually carrying out dehydration and drying and other treatment to sludge, then passes through grate furnace, rotary kiln
It is individually burned, or is sent in boiler of power plant and coal carries out multifuel combustion with fluidized bed incinerator etc..Due to station boiler fuel
Consumption is big, and in-furnace temperature is horizontal high, and flue-gas cleaning devices are perfect, so having place based on station boiler cooperative disposal sludge art
The advantages that reason amount is big, processing speed is fast, innoxious thorough, application at home is increasing.Currently, due to most of thermal power plant
The sludge drying to put into operation-burning engineering belongs to improvement project, and original boiler only matches one kind generally according to the characteristic of design coal
The pulverized coal preparation system of pattern cannot directly receive the sludge of high-moisture percentage, thus it is dry to supplement arrangement sludge drying workshop progress sludge
Change, desiccation workshop and boiler system are relatively independent, and farther out, dewatered sludge is transported to the coal yard of power plant or dedicated sludge storage to distance
Then storehouse is sent into pulverized coal preparation system using Belt Conveying mode, or is directly entered in stove by helical feed, Geldart-D particle and burned.
Airborne dust is had in stacking and transmission process for sludge after desiccation and foul smell distributes, and the sealing performance of belt conveyor system compared with
Difference spreads in plant area and near zone so easily causing foul smell, causes working environment severe, seriously affect power plant's burning sludge
Enthusiasm.
Therefore, Development of Novel pulverized coal preparation system adapts to the requirement that common coal and sludge mix on generating plant pulverized coal boiler, is logical
The important foundation that thermal power plant carries out sludge incineration disposition is crossed, for promoting environmental protection to have positive effect.
