Description
Technical field:
The utility model relates to fixedly double-layer grate coal-fired steam boiler of a kind of novel horizontal.
Background technology:
The a lot of countries in the world today all face the serious nervous problem of the energy, therefore all seek outlet on energy-saving and cost-reducing.But most coal-fired steam boilers in the market (≤1t/h) because the factor of cost, cause the structure of boiler to be restricted, cause the utilization rate of fuel lower, fuel combustion is insufficient, cause consumption bigger, for example, DZL1-0.7-A type boiler oil consumption is generally about 180kg/h.The thermal efficiency of boiler is lower, and JB/T10094-2002 is defined as 68% (the fixedly hand-fired boiler of＜1t/h).Dirt, dust are removed difficulty in the boiler body, the desulfurization and dedusting DeGrain, and environmental pollution is bigger, is not suitable for large-scale popularizing and uses.
Summary of the invention:
The purpose of this utility model is to avoid above-mentioned existing weak point, provide a kind of fuel combustion abundant, effect of coal saving is obvious, (general consumption is about 160kg/h), thermal efficiency height (efficient is generally about 78%), heating surface area reaches about 33 square metres, and the desulfurization and dedusting effect is (soot emissions reach Lin Geman I level) obviously, and water level and steam superpressure be the boiler of control automatically.This boiler structure is simple, and is easy to install, safety, and the fuel tolerance of boiler is strong.
Technical solution of the present utility model provides fixedly double-layer grate coal-fired steam boiler of a kind of novel horizontal, and its structure is single drum longitudinal, three backhauls of extreme misery pipe, horizontal fixedly double-layer grate.This structure is that vertical layout of drum (3) is connected with down-comer (18), down-comer (18) and left side collection case (12), right collection case (22) connects and composes the water-cooled framework of boiler, preceding collection case (17), the fairlead (1) of middle collection case (14) and boiler front portion, furnace grate tube (16) constitutes the low temperature combustor (15) of boiler, there is front smoke box (2) front portion of drum (3), there is back smoke box (6) at the rear portion, inside is equipped with threaded flue (4), the rear portion of boiler is furnished with first convection bank (9), the boiler furnace both sides are furnished with water screen tube (13), its back wall anterior and low temperature combustor (15), the midfeather of boiler (20) constitutes the high temperature combustors (19) of boiler, and the front portion of boiler is equipped with electrical control cubicles (23).
Water level and steam superpressure automatic controller are arranged in the above-mentioned electrical control cubicles (23);
Furnace grate tube (16) spacing of above-mentioned low temperature combustor (15) is 105 ± 5mm, becomes the inclination angle of 10～12 degree with level;
Totally 6 of the fairleads (1) of above-mentioned low temperature combustor (15) are and are symmetrically arranged.
The utility model has the advantages that rational in infrastructurely, design properly that overall volume is less, cost performance is higher, installs simple, easy to maintenance, handling safety, the adaptability of coal is stronger, and the utilization rate of fuel is higher, thermal efficiency height, heating surface area is big, and the probability that tube sheet cracks is lower, the service life of boiler is longer, have the desulfuration in furnace dust removing effects, and effect is obvious, this boiler can be placed use in the open.

The specific embodiment:
Drum (3) is simplified for the Φ's 1200 that rolls with the 20g shell plate, vertically arrange and down-comer (18) (the 20# seamless steel pipe of employing) welding, down-comer (18) constitutes the water-cooled framework of boiler again with a left side (12), right (22) collection casees (the 20# seamless steel pipe of employing) welding, before collection case (17), middle collection case (14) fairlead (1), the furnace grate tube (16) of (employing seamless steel pipe) and boiler front portion again, constitute the low temperature combustor (15) (coal gasification chamber) of boiler, make bunker coal gasify, decompose, reduce and generate coal gas, finish the coal gasification process at this.The seamless steel pipe that fairlead (1) adopts is made, and is total to the six roots of sensation, and for being symmetrically arranged, the seamless steel pipe that furnace grate tube (16) adopts is made, and spacing is 105 ± 5mm, becomes the inclination angle of 10 ~ 20 degree with level.The flue gas of coal gas and high temperature enters burner hearth---the high temperature combustion zone of being encircled a city by water screen tube (13) (adopting the 20# seamless steel pipe) through burner, mix with air at this, form strong burning, and by radiation with the heat transferred WATER AS FLOW MEDIUM, high-temperature flue gas enters by water screen tube (13) after midfeather (20) refraction, the burner hearth rear portion that first convection bank (9) (adopting the 20# seamless steel pipe) is formed, finish first backhaul of boiler, high-temperature flue gas is by radiation, the mode of convection current is with the heat transferred water-cooling wall, medium in the convection bank---water, flue gas after the cooling is through the effect of superrefraction simultaneously, make a large amount of dust deposits in the bottom and expansion chamber (21) of high temperature combustors (19), regularly clean out then by shoot door.Flue gas imports back smoke box (6) by being communicated with flue, enter part smoke pipe---the first smoke pipe district in the drum (3), finish second backhaul of boiler smoke, flue gas is again after front smoke box (2) is turned back, enter the second smoke pipe district in the drum (3), form the 3rd backhaul of boiler smoke, last flue gas enters desulfurizing dust-collector (7), air-introduced machine (10), chimney (8) and is discharged in the atmosphere through connecting flue (5).
Operation principle:
When hot flue gas passed through midfeather (20), because the effect of its baffling, the dust that carries in the flue gas carried out the subsiding and purifying processing first time.Flue gas is at the convection heating surface that enters boiler through combustor exit, reach the purpose of purifying and dedusting again through baffling effect for the second time, then through after smoke box (6) enter boiler mainly to stream interface---first smoke pipe tube bank district, enter the cleaner that second smoke pipe tube bank district, outlet flue, flue enter afterbody turning back through front smoke box (2), and force to carry out gas cleaning dust removal process for the third time, after air-introduced machine import chimney and be discharged in the atmosphere.
