Abstract
A kind of novel double-layer grate plane undaform anti-burn grate boiler, its upper strata water pipe furnace grate is designed to the plane undaform, thereby improved the gas permeability of anti-burn grate, improved anti-burning intensity, cause the combustion intensity of whole stove and exert oneself all to be improved, be applicable to the manufacturing of of new generation vertical and horizontal double-layer grate back firing boiler.
Description
The invention provides a kind of boiler with two-layer fire grates of high-strength burning.
There are following three defectives in the boiler with two-layer fire grates of extensively having been promoted at present:
1. combustion intensity is low, and it is low to exert oneself, and causes the waste of guiding principle material.
2. water pipe furnace grate ventilating air permeability in upper strata is poor, and combustion intensity is low, forces to mend on lower floor's fire grate to add soft coal, causes over-emitting black exhaust.
3. fouling, plugging, burning damage accident easily take place in the upper grate water pipe.
Causing the main cause of these defectives, is because the same crack of last layer plane water pipe furnace grate will be the maximal clearance with the gap of freely not leaving out by mistake soft coal.This plane limit ventilation gap makes this stove and accessory that above inherent shortcoming be arranged.
The present invention is according to the coal piling mechanics principle, the upper strata water pipe furnace grate is designed to the plane undaform, replaces plane clearance with bigger gap, inclined-plane, makes that freely to leave out by mistake the soft coal amount suitable with plane clearance, but strengthened ventilation gap, thereby improved the anti-combustion intensity of burning of upper grate.
In conjunction with being the accompanying drawing of example, the combustion mechanism of this structure is illustrated with vertical double fire grate back firing boiler.
Among the figure: (2) are plane, upper strata undaform water pipe furnace grate.
Essence for convenience of explanation, plane undaform fire grate is realized like this: all odd number fire bars of a plane fire grate are moved down a distance, promptly.
If the horizontal maximal clearance between the fire grate of plane is a, move down back this gap and become gap, inclined-plane a ', its angle is θ, a '=(a)/(COS θ), if top, gap coal piling x wire heavily is W, the horizontal clearance a pressure of reaching the standard grade is P, and then a ' the pressure of reaching the standard grade in gap, inclined-plane is P '=(W)/(a ')=PCOS θ P '＜P
Though push away to such an extent that gap, inclined-plane a ' has increased thus, by the minimizing of coal piling pressure thereon, freely the amount of leaving out by mistake is roughly constant so can make coal piling, and then a '＞a increases ventilation gap, has therefore improved the combustion intensity of upper grate.Add that flat-wave and fixed fire grate has strong combustion intensity positive feedback.The combustion intensity of whole boiler gets a greater increase.
Double-layer grate of the present invention plane undaform back firing boiler can be made vertical or horizontal.
Claims (1)
- A kind of vertical or horizontal double-layer grate plane undaform anti-burn grate boiler is characterized in that upper strata water pipe anti-burn grate is that the plane undaform is arranged.
