Abstract
The utility model relates to a back-burning device of semi-gas coal boiler. One part of a boiler chamber and a boiler bottom are divided into two parts by a baffle plate, and two combustion chambers are formed in the boiler chamber. The height of the baffle plate in the boiler chamber is half of the height of the boiler chamber. Two parts of the divided boiler bottom are all provided with air doors which can respectively control the air inlet of the combustion chambers. The two combustion chambers are alternated to change the coal by the boiler which adopts the utility model, and the coal in the two combustion chambers can mutually radiated for igniting. The coal can not be ignited when the coal is changed, the firing is quick, and the fire power is uniform. The combustion flame of the combusted coal can keep continuously vigorous.
Description
The utility model relates to a kind of burner that is used for counter-burning type semi-coal gas coal-burning boiler.
The burner hearth of existing counter-burning type semi-coal gas boiler is darker, once can add more coal, coal is ignited from the top of coal with ignition substance again, progressively gasification after coal is ignited, and slowly burning downwards, formed semi-coal gas is admitted to secondary combustion chamber and carries out second-time burning, uses this class boiler fired coal combustion fully, smokelessly.But must change coal again after burning down a stove coal, whenever change a dant and will draw a tempering, so not only the flame of fired coal combustion can not keep continuing, vigorous, but also to consume a large amount of fire-lighters, on fire also slow, firepower is inhomogeneous in combustion process.
The utility model purpose be to provide a kind of change coal need not ignite, on fire fast, can make fired coal combustion flame keep the burner of lasting, even, vigorous counter-burning type semi-coal gas coal-burning boiler.
For achieving the above object, the utility model solution is with dividing plate the part of burner hearth to be separated into two parts together with furnace bottom, in burner hearth, form two combustion chambers, dividing plate height in the burner hearth is about half of furnace height, can control the combustion period of two combustion chambers like this, make two combustion chambers change coal in turn.Coal when a Room is in burning during the most productive period, coal is just in time changed in another chamber, and utilize heat radiation principle, the coal of two Room can be ignited mutually, and the firepower of two combustion chambers can replenish when burning mutually, guarantee that the fired coal combustion flame in the whole burner hearth keeps lasting, even, vigorous, the furnace bottom two parts that are separated out are equipped with air door, control the air intake of combustion chamber respectively.
The utility model because of adopt dividing plate with the part of burner hearth together with the furnace bottom separated into two parts, in burner hearth, form two combustion chambers, so can make two combustion chambers change coal in turn, the coal that guarantees two Room radiation mutually ignites, change coal and must not ignite again, and on fire soon.The firepower that can also guarantee simultaneously two combustion chambers can replenish when burning mutually, makes in the whole combustion process firepower even, and the combustion flame protection continues vigorous, and can control the firepower of combustion chamber by set left and right sides air door respectively.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1--be the utility model cutaway view.
Referring to Fig. 1, the utility model is the improvement to existing counter-burning type semi-coal gas coal-burning boiler, this boiler mainly is made up of air door 1, burner hearth 2, furnace chamber 3, semi-coal gas outlet 5, secondary air mouth 6, secondary combustion chamber 7, fire bars 8, furnace bottom 9, with dividing plate 4 part of burner hearth 2 is separated into two parts together with furnace bottom 9, two parts of the furnace bottom 9 that is separated out are equipped with air door 1, can control firepower size in the combustion chamber respectively.Dividing plate 4 bottoms are fixed on the bottom of furnace bottom 9, the dividing plate 4 that is contained in the burner hearth 2 is interlayer, interlayer dividing plate 4 links together with furnace chamber 3, thereby the part of burner hearth 2 is separated into two combustion chambers, the height of interlayer dividing plate 4 is about half of furnace height, guarantee that when coal is changed in the combustion chamber can the overflow coal that burning to another of part of coal is indoor, be convenient to coal is ignited.The dividing plate that is contained in the burner hearth is an interlayer, can make the cavity UNICOM of furnace chamber 3 and interlayer dividing plate 4, and the cooling waters in the furnace chamber 3 can enter the cavity of interlayer dividing plate 4, prevents that the dividing plates 4 in the burner hearth 2 from being burnt out.For the coal after changing can be ignited by radiation rapidly, triangle is made at interlayer dividing plate 4 tops in the burner hearth 2.
Claims (3)
