Description
Technical field
The present invention relates to CFBB, particularly a kind of horizontal circulating fluidized bed boiler.
Background technology
Boiler is the equipment that changes the chemical energy in the fossil fuel (referring to coal) into heat energy more; The fundamental reaction that chemical energy in the coal changes heat energy into is burning; Carbon and protium oxidation (burning) in the process of burning in the coal discharge heat energy; But contain sulphur and nitrogen compound in the coal, sulphur compound burning back generates sulfur dioxide, and nitrogen compound burning back generates nitrogen oxide (NOx).These two oxides discharge in atmosphere, form acid rain, atmosphere is produced pollute.In boiler design, can change coal chemistry into heat energy (efficiency of combustion is high) and effectively remove sulfur dioxide and nitrogen oxides emission expeditiously, reduce atmosphere pollution, be that people pursue.In the basic coal-burning boiler, not said two devices perfect basically also not the having of uniting.Aspect efficiency of combustion, the coal-powder boiler burner hearth is high, and fuel time of staying in burner hearth is long, and used bunker coal thin (70% can pass through 200 purpose sieves) can fully burn, so ignition temperature high (about 1350 ℃) (efficiency of combustion is high); The used coal cinder of grate furnace is big; During burning; Though the time of staying to coal can be controlled, burner hearth is not high, and the flue gas that coal generates on the fire grate, the ickings time of staying in burner hearth is short; Can not fully burn, so ignition temperature is lower than coal-powder boiler (about 1200 ℃) (efficiency of combustion yet keeps higher level); Aspect effective removal sulfur dioxide and nitrogen oxides emission, the ignition temperature of coal-powder boiler and grate furnace all is higher than to be taked can not effectively remove sulfur dioxide and nitrogen oxides emission to the absorption of sulphur in the sulfur dioxide and the reduction temperature of nitrogen oxide (about 600 ℃).The present vertical circulation fluidized-bed combustion boiler that generally uses; Though when keeping than high burning efficiency; Can accomplish comparatively effectively to reduce the discharging of sulfur dioxide and nitrogen oxide; Aspect efficiency of combustion; The vertical circulation fluid bed boiler furnace is a vertical furnace chamber; Burner hearth is high; The bed material is under the effect of air compartment fluidization air; Fluidized bed combustion in burner hearth; When burner hearth burns the time of staying long, most of fire coal can both fully burn, ignition temperature (about 900 ℃) is lower than grate furnace; But the fluidized bed combustion turbulivity is high, mass-and heat-transfer degree also high (efficiency of combustion yet keeps higher level); Aspect effective removal sulfur dioxide and nitrogen oxides emission; The vertical circulation fluid bed; Added lime stone in the bed material; Because ignition temperature is fit to limestone calcination; Lime stone after the calcining becomes lime and comes the sulfur dioxide in the absorption from flue gas; Generate and stablize calcium sulfate; Because bed material turbulent flow exists reaction is carried out continuously; Again owing to roughly be divided into two parts in the burner hearth; Top is moving bed; The bottom is the bubble bed, and the bottom bed material is thick, and the reducing gas of insufficient generation of burning can play reduction reaction with nitrogen oxide the nitrogen oxide in the flue gas is reduced.But, the first, vertical circulation fluid bed vertical furnace chamber structure can not make the bed material move horizontally with burner hearth bottom bubble bed bed material thick; Visual this part fluidized bed furnace for not moving horizontally, when burning of bed material and desulfurization were denitrogenated, this part was not to remove the nitrogen rule segmentation according to order burning successively of bed material and desulfurization to carry out; Cause deficiency to be; On the one hand, make fuel can not fully burn (exist fuel not burn and flow out phenomenon), influence boiler efficiency and improve; On the other hand, the product (calcium sulfide) that makes advanced and formerly ongoing bed material desulphurization reaction can accomplish desulphurization reaction by laggard bed material and before robbing stops and go on, and the reducing gas that the reducing zone produces (like methane. ethane. ammonia etc.) possibly fail to participate in reaction and promptly go out burner hearth; Desulfurization is denitrogenated not thorough; Influence the boiler desulfurization efficiencies of nitrogen removal. the second, vertical circulation fluid bed vertical furnace chamber structure will realize a materials flow burning, air compartment fluidization air pressure is just bigger below the burner hearth; Cause deficiency to be; Vertical furnace chamber internal pressure equalization point improves (raisings of burner hearth combustion pressure), consequently the dosing of bed material, circulate and strile-back and the deslagging influence that is under pressure, it is inconvenient to operate; The 3rd; There is the restriction of transmission transport disengaging height in vertical circulation fluid bed vertical furnace chamber structure, and the bed material speed that surpasses this height will be little with the fluidization air velocity contrast; Make the bed material can not keep receiving the effect of air compartment fluidization air; Cause deficiency to be, the burning of bed material is obstructed, and boiler combustion efficiency can not further improve; The 4th, in the vertical circulation sulfuration bed vertical burner hearth, see from redox angle; Top moving bed part also can be considered zoneofoxidation; Bottom bubble bed part also can be considered the reducing zone, and at these two district's intersections, vertical furnace chamber inside is washed away by these two mutual actings in conjunction in district and the dirty bed material of eminence; Cause deficiency to be, the burner hearth corrosion-vulnerable is bigger with wearing and tearing; The 5th, the space is large but impractical in the vertical circulation sulfuration bed vertical burner hearth, and hot bed materials and heating surface do not match, and influence boiler efficiency.
Summary of the invention
The technical problem that the present invention will solve is that burning of bed material and the desulfurization that vertical circulation fluidized-bed combustion boiler vertical furnace chamber structure exists denitrogenated and can not be carried out according to bed material successively order, influences boiler combustion efficiency and improves and the desulfurization efficiencies of nitrogen removal; The pressure in the burner hearth equalization point improves, and the dosing of bed material, circulates and strile-backs and the deslagging influence that is under pressure, and operation is inconvenient; Have the restriction of transmission transport disengaging height, boiler combustion efficiency can not further improve; And the space is large but impractical in the burner hearth, and hot bed materials and heating surface do not match, and influence boiler efficiency; The deficiency of burner hearth corrosion-vulnerable and wearing and tearing.
