The specific embodiment
Embodiment 1
A kind of horizontal anti-many backhauls of burning energy-saving environmental protection boiler; Shown in Fig. 1-6; Comprise: body of heater, vapour, water cavity 1, water inlet pipe 13, vapour, water out 102; Burner hearth both sides in the described body of heater are provided with water screen tube 10; Two side water wall tubes, 10 tops are communicated with vapour, water cavity 1 through left both sides tube bank flue 18, right both sides tube bank flue 17 respectively, and two side water wall tubes, 10 bottoms are communicated with left side collection case 11, right collection case 12 respectively, are divided into upper combustion chamber and lower combustion chamber by water comb 3 and lower floor's fire grate 6 in the burner hearth; Water comb 3 is anti-" L " shape, and top is communicated with vapour, water cavity 1, and the bottom is communicated with preceding collection case 5, and burner hearth is that water comb 3 is anti-" L " shape at the back, and top is communicated with vapour, water cavity 1, and the bottom is communicated with preceding collection case 5; The burner hearth rear portion is provided with middle wall 16; Middle wall 16 is provided with mouth 1601 at lower combustion chamber's rear lower; Upper combustion chamber is communicated with lower combustion chamber through water comb 3; Lower combustion chamber is communicated with rear portion tube bank flue 14, left and right sides tube bank flue 18, right both sides tube bank flue 17, front smoke chamber 2, smoke pipe bundle 104, rear smoke chamber 4 through mouth 1601 successively, by rear smoke chamber 4 to chimney.
Described lower floor fire grate 6 is fixed casting furnace grate.
Described upper combustion chamber is provided with coal-feeding door 7, and lower combustion chamber is provided with the door 8 that pokes fire, and the cigarette ash chamber 15 of lower floor's fire grate 6 bottoms is provided with shoot door 9, and tube bank flue 14 bottoms, rear portion are provided with shoot door 1401.
Described front smoke chamber 2, rear smoke chamber 4, service hatch, vapour, water out 102 all are provided with ring flange; Described body of heater, vapour, water cavity 1 and ring flange all are provided with heat-insulation layer.Smoke box place, described back is provided with air-introduced machine.At first, open the coal-feeding door 7 of combustion chamber when firing, close lower combustion chamber poke fire the door 8.
One, the process of lighting a fire
1, behind the pilot fuel, the unlatching air-introduced machine that is interrupted, treat that fuel combustion is vigorous after, beginning is manual fills out coal, and suitably pokes fire, and beginning is toward the indoor coal of filling out 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, and 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 is should grate smooth, and flame gathers evenly, sufficient combustion, and combustion chamber draft remains on the 2-3 millimeter of water, and all shoot doors, the door that pokes fire are closed.
2, in combustion process, note often poking fire, prevent coal seam frame and bulk coking, in time clear up the lime-ash in the fire grate gap, overdo unimpeded with assurance.In use; System's backwater gets into front smoke box through water inlet pipe; A part is through getting into vapour, water cavity behind the water screen tube of the left and right sides; Another part gets into vapour, water cavity through water screen tube behind the collection case respectively again through preceding collection case about communicating pipe gets into, the outlet HTHP vapour of vapour, water cavity, water through draw vapour, water pump is drawn.Experiment proof: horizontal anti-many backhauls of the burning energy-saving environmental protection boiler of the utility model; Its combustion chamber is under the effect of air-introduced machine; Flue gas through under the water pipe furnace grate instead in lower combustion chamber, in lower combustion chamber,, played the effect that eliminates smoke through fully burning; Flue gas therefrom gets into smoke pipe bundle, the rear smoke chamber in the tube bank flue, front smoke chamber, vapour, water cavity of rear portion tube bank flue, the left and right sides behind the mouth of wall successively, and rear smoke chamber is to chimney.Flue gas not only lets medium carry out sufficient heat exchange through so many backhauls, has also effectively guaranteed environmental protection requirement.
Experiment proof: horizontal anti-many backhauls of the burning energy-saving environmental protection boiler of the utility model; Its combustion chamber is under the effect of air-introduced machine; Flue gas through under the water pipe furnace grate instead in lower combustion chamber, in lower combustion chamber,, played the effect that eliminates smoke through fully burning; Flue gas therefrom gets into smoke pipe bundle, the rear smoke chamber in the tube bank flue, front smoke chamber, vapour, water cavity of rear portion tube bank flue, the left and right sides behind the mouth of wall successively, and rear smoke chamber is to chimney.Flue gas not only lets medium carry out sufficient heat exchange through so many backhauls, has also effectively guaranteed environmental protection requirement.
Embodiment 2
