Abstract
The utility model relates to a compartment combustion boiler, characterized by are equipped with preceding arc in boiler body drum lower part and encircle, back arc and the grate constitutes high temperature combustion chamber respectively, burn the cinder chamber, and the afterburning chamber is constituteed relatively to the front and back arc, and the back arc encircles and the drum constitutes the deposit room. The fire coal is combusted in the furnace by sections in chambers. The soot is burnt at high temperature, the combustion is sufficient, and the smoke abatement is achieved. And settling in a settling chamber to remove dust. The carbon content of the ash is low, so that the energy is saved. So as to protect the environment, reduce consumption and save energy.
Description
The utility model relates to a kind of coal-burning installation, particularly a kind of grate firing coal-burning boiler.
At present, commercially available grate firing coal-burning boiler mostly is hybrid combustor.Because of grate firing boiler, coal is in stove, and burning divides several stages, all carries out in mixing chamber, influence each other, be difficult to have a stable high-temperature region, coal combustion is incomplete, produces volume of smoke, enter atmosphere, pollute, especially to high-volatile coal, this phenomenon is even more serious.For the difficulty coal of catching fire, long or ignite untimelyly because of ignitor firing time, coal uncombusted and discharging makes ash content carbon excessive, wastes energy.
The purpose of this utility model provides a kind of locellus burner, is provided with high temperature combustors, and burning chamber, secondary combustion chamber and expansion chamber device make the coal combustion fully, energy savings, and smoke abatement and dust control is in order to environmental protection.
The utility model technical solution is such, be provided with preceding arch (3) in drum (1) lower coal lock (5) inboard, and the high temperature combustors of forming with fire grate (7) (6), rear side is provided with back arch (10) relatively, and form burning chamber (9) with fire grate (7), preceding arch (3) and the relative secondary combustion chamber (11) of forming of back arch (10), forward and backward arch can be multiaspect shape arc arch, and the back arch abutment is connected with secondary to airduct (12).
When coal from coal bunker, promoted to send into the high temperature combustors burning by fire grate through the coal lock, remaining material enters burning chamber (9) and burns away, two Room burning residue combustible, entering secondary combustion chamber [11] gives under airduct [12] the air intake effect at secondary, in secondary combustion chamber burning, make in the coal combustible heat release of burning as far as possible, obtain utilizing, can not burning smoke dirt through sedimentation, reach the smoke abatement and dust control purpose.
Characteristics of the present utility model mainly are the locellus burnings, and the coal combustion fully, secondary air is combustion-supporting, and smoke abatement and dust control improves temperature in the stove, energy savings does not increase equipment, rationally transforms and lays and only structure in the stove has been done some, strict physical dimension is intended to make the flammable composition of coal, the heat release of burning as far as possible, energy savings, incombustible composition, the sedimentation of folding cigarette reaches smoke abatement and dust control.
The utility model structure is provided by the following drawings and embodiment.
Figure is the utility model vertical profile schematic diagram
The utility model specifically can be implemented like this, boiler body top is provided with drum (1), smoke pipe (2) is installed in it, or other heat transfer forms, there is outlet flue (14) at the angle on the rear side, coal bunker (4) is arranged at drum (1) bottom, coal lock (5) is arranged in the inner part, preceding arch (3), and the high temperature combustors of forming with fire grate (7) (6), rear side has back arch (10) relatively, and the burning chamber (9) that forms with fire grate (7), preceding arch (3) and the relative secondary combustion chamber (11) of forming of back arch (10), back arch (10) and drum (1) composition expansion chamber (13), the backarc arch abutment is connected with secondary and gives airduct (12), and the front and back arch also can be multiaspect shape arc arch.The boiler body base portion has fire grate (7), and there is slag notch (8) back, and fire grate (7) is a chain-type, also driving or reciprocating type.
In the utility model, coal specifically is burning like this, the fire grate of coal passive movement (7), from coal bunker (4), through coal lock (5), send into high temperature combustors (6), coal is when just entering high temperature combustors, the heat that is stored by preceding arch (3) toasts, ignites, and volatile matter is at first separated out burning in the coal, and coal is continued to send backward by fire grate (7), in high temperature combustors, the rear portion, mix with a large amount of air that enter under the fire grate (7), a large amount of heats are emitted in redox fast, make high temperature combustors form distinctive high temperature, the volatile matter of separating out in the coal is burnt.Kindling for difficulty, because high temperature combustors is not arranged heating surface, heat is not absorbed, and the arc of preceding arch focuses in addition, and the donor accumulation of heat makes coal that the condition of fully catching fire and igniting be arranged, thereby just catches fire easily yet.Because preceding arch [3] makes high temperature combustors [6] likeness in form small room, flue gas forms turbulent flow, plays certain inhibition again.Prolong the time of staying of flue gas, be able to abundant burning.At high temperature combustors (6) not by the solid of completing combustion, continued to be fed into burning chamber (9) by fire grate (7),, burn away mixing with an amount of air that enters under the fire grate (7) under the baking of back arch (10), remaining combustible is fully burnt, improve the heat release conversion of coal as far as possible.At high temperature combustors (6) not by the mist of completing combustion, because the effect of air inducing, enter secondary combustion chamber (11), mix with the flue gas that burning chamber (9) burning is emitted, flue-gas temperature at this moment is very high, contain the imperfect combustion gas of part, because of airborne oxygen deficiency, be difficult to burn away, send into high-speed air for airduct (12) by secondary, supplemental oxygen is stirred and is mixed, and makes its heat release utilization of fully burning.Through burning several times, the flue gas combustible is burnt, and reaches the purpose of smoke elimination.Incombustible grit, because stenosis area forms and enters expansion chamber (13) at a high speed between drum (1) and back arch (10), again owing to the actual internal area sudden enlargement, the flue dust reduction of speed, grit is sedimentation rapidly under the gravity effect of self, reaches the purpose of dedusting.It is many, both energy-conservation that the utility model adapts to coal, and smoke abatement and dust control again is expected to fundamentally to reach energy-conservation, the smoke elimination of grate firing boiler, the purpose of dedusting.
Claims (3)
1, a kind of locellus burning boiler, drum (1) is arranged at boiler body top, smoke pipe (2) is housed in it, there is outlet flue (14) at the angle on the back, coal bunker (4) is arranged at drum (1) bottom, coal lock (5) is arranged in the inner part, expansion chamber (13), the boiler body base portion has fire grate (7), and the back has slag notch (8) to constitute relatively, and there is preceding arch (3) its feature drum (1) lower coal lock (5) inboard, and the high temperature combustors of forming with fire grate (7) (6), rear side has back arch (10) relatively, and forms burning chamber (9) with fire grate (7), and the relative secondary combustion chamber (11) of forming with back arch [10] of preceding arch (3) constitutes.
