Abstract
The utility model relates to a continuous gasification coal combustion boiler with a tower-type rotating grate. The utility model is characterized in that a gasification chamber which forms the shape of a right circular truncated cone is composed of an upper and a down ring headers, an inner water-wall tube and fins; a ring secondary combustion chamber is formed between the inner water-wall tube and an outer water-wall tube; a tower-type grate which is arranged in the center of the gasification chamber is composed of a plurality of grate segments of the same structure, and the grate segments are overlapped and fixed; strip-shaped vent holes are uniformly arranged on the inner and the outer column surfaces of each grate segment; the tower type grate is fixed on a chassis whose underside is provided with a toothed ring, and a toothed ring pushing mechanism is arranged beside the chassis. The utility model has the advantages that coal can be continuously gasified, and can be combusted sufficiently; the original dust exhausting concentration is lower than 100 mg/HM<3>, the blackness approaches to zero, and the effect of environmental protection is outstanding; the utility model is a great change for the combustion mode of coal combustion boilers.
Description
The utility model belongs to coal-burning boiler.
With coal gasification combustion is to reduce a kind of important technology scheme that boiler dust pollutes, in the past by a kind of coal-burning boiler of forming by water jacket, fixed grate and combustion chamber that partly gasifies, this boiler batch (-type) coal, slagging-off, the discontinuous heat supply, because manual throwing coal, slagging-off, labour intensity is big, and the intermitting heating mode is undesirable in addition, and this boiler is not used at present.
The purpose of this utility model be to provide a kind of can continuous gasification, coal-burning boiler that environment protecting is good.
The purpose of this utility model realizes by technical scheme shown in the drawings, it comprises drum, convection heating surface, furnace wall, dreg removing system, water screen tube, water screen tube of the present utility model and upper and lower annular header are welded into one, several vapour that are connected with closed circuit, water pipe 7 are arranged on the upper and lower annular header, 1 welding of interior water screen tube fin 10, uniform grid hole, interior water screen tube middle part 2, upper and lower annular header, interior water screen tube, fin constitute a normal cone platform shape vaporizer 5, looping secondary combustion chamber 3 between interior water screen tube and the outer water screen tube; Tower fire grate 4 of center arrangement at vaporizer, tower fire grate is fixedly formed by identical fire grate joint 6 stacks of a plurality of structures, fire grate joint inside is right cylinder 13, the outside is normal cone platform shape, equal Strap air vent 14 on the inside and outside cylinder, an eccentric tower lid 12 is fixed at the top of tower fire grate, tower fire grate is fixed on the chassis 8, ring gear 11 is arranged below the chassis, the chassis is other fixes a ring gear pushing mechanism 9 that is made of motor, eccentric wheel, chute, connecting rod and push rod, promotes tower fire grate and rotates.
Top, coal-fired autopneumatolysis chamber of the present utility model adds, fire coal flows from top to bottom, steam and wind enter the turriform grate wind chamber by pipeline separately, mix the back and send into vaporizer by the stripe shape air vent on the tower fire grate, coal drying, destructive distillation, reduction-oxidation successively in the combustion chamber, burn, the coal gas that is produced enters annular secondary combustion chamber through the grid hole, and the fire grate that lime-ash is rotated discharges out of the furnace.The utility model makes fire coal continuous gasification in vaporizer, and coal can fully burn, and is the major transformation of coal-burning boiler combustion system, and the every standard cubic meter of original dust exhausting concentration of the present utility model is lower than 100 milligrams, and blackness approaches zero.Its environment protecting is very outstanding, social benefit and economic benefit highly significant.
Accompanying drawing 1 is the utility model front view (partial cutaway);
Accompanying drawing 2 is the utility model vertical view (partial cutaway);
Accompanying drawing 3 is the tower fire grate structure enlarged diagram of the utility model.
Embodiment
Heating load is the boiler of 1.4MW.Constitute on the normal cone platform shape vaporizer in the round platform 1550 millimeters in footpath by upper and lower annular header, interior water screen tube, fin, the footpath is 1650 millimeters in the following round platform, and interior water screen tube middle part is three layers of grid hole of fork cloth evenly.Tower fire grate is made of three joints, and 1350 millimeters of the following round platform diameters of fire grate joint are gone up 450 millimeters of the following round platform diameters of joint fire grate most, the 4th saves the following of fire grate, even distribution air vent on the interior outer cylinder of circular cone shape fire grate joint, long 80 millimeters of air vent, wide 8 millimeters, the fire grate internode is affixed with bolt.Tower fire grate after the stack is fixed on the chassis, two circle ring gears are arranged below the chassis, 3500 millimeters of outer tooth ring diameters, 3000 millimeters of internal gear diameters, the tooth of internal gear is not equally spaced, the chassis is other fixes a ring gear pushing mechanism that is made of motor, reducing gear, eccentric wheel, chute, connecting rod and push rod, promotes tower fire grate speed change and rotates, and its rotating speed is per hour 10 commentaries on classics on average.The lumen of tower fire grate is an air compartment, and steam pipe and ventilation duct insert air compartment, and steam and air mix the back and enter vaporizer by the bar shaped air vent on the fire grate joint in air compartment.
Claims (3)
