Described vapour, water cavity 1 are communicated with three the tunnel: the one tunnel respectively and are communicated with left side water-cooled grate tube 13, right side water-cooled grate tube 12 respectively; Two the tunnel are communicated with the water pipe furnace grate 5 below the reverse burning chamber 7; Three the tunnel are communicated with two communicating pipe 1005 and communicating pipe 1006 respectively; Described left side water-cooled grate tube 13 is communicated with left side collection case 1003, and right side water-cooled grate tube 12 is communicated with right collection case 1002, collection case 1004 before left side collection case 1003 and right collection case 1002 all are communicated with; Collection case before described water pipe furnace grate 5 is communicated with; Collection case before described communicating pipe 1005 is communicated with, preceding collection case is communicated with water inlet pipe again; Described vapour, water cavity 1 top are provided with service hatch 102, vapour, water out 101, normal pressure mouth and suspension ring respectively; Described vapour, water cavity 1 connect high-order water supply tank, and vapour, water cavity 1 bottom are provided with the blow-off pipe 104 of band valve.Shown in Fig. 5-7.
Flue 3 is restrained by tube bank flue 11 right sides, left side respectively in upper, middle and lower or just combustion chamber 8,7 tops, reverse burning chamber are being communicated with vapour, water cavity 1 by being divided into respectively on described left and right sides water-cooled grate tube 12,13 tops.
Described left both sides tube bank flue 11 and right side tube bank flue 3 are separately positioned on positive combustion chamber 8,7 tops, reverse burning chamber and are connected with vapour, water cavity 1.
The left side of described positive combustion chamber 8 is provided with air blast.
Described vapour, water out 101 are provided with diversion, heat pump.
Described front smoke chamber 9, rear smoke chamber 2, service hatch 102, vapour, water out 101 all are provided with ring flange; Described body of heater, vapour, water cavity 1 and ring flange are provided with heat-insulation layer.
The fire door of positive combustion chamber 8, reverse burning chamber 7 is set before the described body of heater, and the body of heater bottom is provided with stove seat 4, and stove seat 4 is provided with cigarette ash chamber, and stove seat front is provided with gray moving door and shoot door.
It is fixed or moving grate that positive combustion chamber 8 interior fire grates are set before the described body of heater.
Operating position:
One, fires program
At first, open the fire door of positive combustion chamber 8 when firing, close the fire door of reverse burning chamber 7.After the material that ignites burns, turn the control valve of flue gas floss hole 601 down, open air-introduced machine discontinuously, after the material burning of waiting to ignite is vigorous, the manual coal of filling out of beginning, and suitably poke fire, after treating burner hearth completing combustion, open air blast, and beginning is toward the indoor stoking of reverse burning, adjustment ventilates, and makes combustion chamber draft maintain the 2-3 millimeter of water.
2. firing intensity should not increase too soon, avoids each several part to produce excessive thermal stress because of the inequality of being heated.Firing for the first time normally must not be less than 2 hour from the black furnace to the leaving water temperature.
Two, normal working procedure
When 1, normally moving, the operating mode in the burner hearth during each combustion chambers burn answers grate smooth, and flame gathers evenly, be glassy yellow, do not wear the burner of cold wind, the cigarette of emerging from chimney is nattierblue, combustion chamber draft remains on the 2-3mm water column, and all shoot doors, the door that pokes fire are closed.
2. this boiler should burn bituminous lump coal, also can burn bad bituminous coal or bituminous coal and anthracite multifuel combustion, and coal seam thickness is generally grasped at 120-150mm.When with wet coal dust, can adopt the high seam burning.
3. in combustion process, if adopt fixed fire grate should note often poking fire, prevent coal seam frame and bulk coking, anti-burn grate will in time be cleared up the lime-ash in the fire grate gap, overdoes unimpeded with assurance.
In use, collection case before system's backwater enters by water inlet pipe, a part enters vapour, water cavity 1 by left and right sides water-cooled grate tube process, another part enters vapour, water cavity 1 through the both sides water-cooled grate tube of water-cooling wall behind the collection case respectively again through preceding collection case 1004 about communicating pipe enters, through vapour, water out 101 by draw vapour, water pump is drawn.
Experimental results show that: the just contrary horizontal vapour of bilateral-firing environmental protection and energy saving of the utility model, homogeneous solution-type reactor, to enter reverse burning again indoor through cutting off the upper smoke passage under the effect of air blast for the flue gas of its positive combustion chamber, burning in indoor big flourishing of reverse burning again, so its burning fully, the flue gas completely of burning enters smoke pipe bundle in front smoke chamber, vapour, the water cavity, rear smoke chamber after by reverse burning chamber, left and right sides tube bank flue successively to chimney.Behind the tortuous also very long flue of its process, not only carried out sufficient heat exchange, its thermal efficiency height.And the dust in the flue gas falls into the laying dust chamber after through collision repeatedly, and cleaner gas to chimney, enters atmosphere through air-introduced machine.It has reached energy-conservation environmental protection again.Simultaneously, its fault is few, use, easy to maintenance, and be doubled service life.
