Abstract
A water-cooled grate combustor comprises a fixed water-cooled grate, a feed hopper, a feed mechanism, a fixed wind chamber, a combustion chamber and an ash pit, the feed hopper is arranged on the front upper part of the combustion chamber, the feed mechanism is arranged in front of the hopper, the fixed wind chamber is arranged under the grate, the combustion chamber is arranged upon the grate, and the ash pit is arranged at the front lower end of the grate. The technical points are as follows: the fixed water-cooled grate is downwardly inclined by 1 to 30 degrees along the moving direction of fuel, the arrangement direction of the tubes of the fixed water-cooled grate accords with the moving direction of the fuel, headers with water inlets and water outlets are perpendicularly connected with the upper and the lower ends of the tubes of the fixed water-cooled grate, leakage-proof spacing baffles which are lapped at the front and the rear or the left and the right are evenly fixed between each two neighboring tubes of the fixed water-cooled grate, and an intake passage is reserved between each two neighboring spacing baffles. Because the grate of the fixed and inclined water-cooled grate combustor provided by the invention is cooled by water, the grate cannot be burnt out by high temperature, the maintenance rate is low, and coal and biomass can be burnt.
Description
Technical field
The invention belongs to fuel boiler burner technical field, a kind of specifically water-cooled grate burner of the continuous cleaning burning device to fuel.
Background technology
Existing coal-fired combusting device mainly contains the burner that dusts, traveling-grate stoker burner, reciprocal grate burner etc.The main problem that exists is that maintenance rate is high, coal adaptability difference and can not burn living beings etc.Existing coal-burning boiler is made up of burner hearth, fire grate, air compartment usually.Normally in burner hearth, add the last layer coal during this boiler shutdown and carry out cold stoking, when opening stove, blow again, still will consume a large amount of fire coals during therefore this boiler shutdown.And this boiler is the top that coal is added to burner hearth charcoal fire layer, coal is taken fire, therefore from the bottom; Be prone to produce during burning black smoke, burning not thoroughly, the thermal efficiency is low, again because this boiler must burn particulate coal, so fuel cost is high; Burden for users is heavy, and boiler grate can't carry out water-cooled, and the fire grate temperature is too high fragile; Operational reliability is poor, and often blowing out maintenance has brought inconvenience for the energy-conserving and environment-protective of coal-burning boiler and normal the use.
Summary of the invention
The water-cooled grate burner that the purpose of this invention is to provide a kind of continuous cleaning burning device to fuel.
The objective of the invention is to realize like this: it includes fixedly water-cooled grate; There is loading hopper the front portion, combustion chamber; There is feed mechanism the loading hopper front, the fixedly air compartment below the fire grate, the combustion chamber on fire grate top; The grey pit of the preceding lower end of fire grate; It is characterized in that: fixedly water-cooled grate is along downward-sloping 1～30 degree of the direction of motion of fuel, and fixedly the arranged direction of water-cooled grate tube is consistent with the direction of motion of fuel for this, is provided with perpendicular continuous and have a header tank of intake-outlet at the two ends up and down of water-cooled grate tube; Adjacent two fixedly evenly be set with between the water-cooled grate tube before and after or about the spacing catch of overlap joint, leave air intake passage at two adjacent spacing catch.
Spacing catch of the present invention is to recessed arcuate structure or plane-shaped structure.
Fixedly installing between spacing catch of the present invention and the water-cooled grate tube is fixing Welding Structure.
The present invention also comprise described loading hopper bottom along the front and back of fuel motion direction openings all, its open front position links to each other with feed mechanism, and the rear portion aperture position communicates with the combustion chamber.
The present invention has following advantage:
1, constant tilt provided by the invention is arranged the water-cooled grate combustion chamber, owing in the fire grate water-cooled is arranged, high temperature burning-tolerant, maintenance rate are low, can burn coal and living beings simultaneously.
2, since adjacent two fixedly evenly be set with between the water-cooled grate tube before and after or about the spacing catch of overlap joint; Two spacing catch adjacent leave air intake passage; Can improve the fuel secondary greatly and fully burn, play preventing that fuel from spilling again.
3, the present invention also has rational in infrastructure, safe and reliable, advantages such as range of application is wide, fuel availability is high, long service life.
