Abstract

The utility model provides a smoke purification type coal boiler, which comprises a combustion chamber and an ash gathering chamber which are divided by a water-through grate bar, a water jacket boiler body, a chimney, an ash removal opening, a draught fan, etc. The utility model is characterized in that two combustion chambers and two ash gathering chambers are arranged respectively, wherein the first combustion chamber is communicated with the second combustion chamber; the first ash gathering chamber is separated from the second ash gathering chamber through a partition wall; the second ash gathering chamber is communicated with the chimney of which the diameter presents a step shape of which the upper part is small and the lower part is big. In addition, the upper part of the second combustion chamber is provided with an air intake regulating opening. Due to the two combustion chambers are communicated, the flue gas produced by the fired coal can be discharged through a fierce fire layer of the second combustion chamber, therefore the flue gas which are not be sufficiently burnt in a boiler chamber can be sufficiently burnt in the process of leading to the chimney, and consequently, the smoke dust can not be seen almost at a chimney outlet, therefore not only can the environment not be polluted but also the heat efficiency of the boiler can be increased.

Description

Clean cigarette coal-burning boiler

Technical field: the utility model relates to a kind of coal-burning boiler.

Background technology: at present, still have with serious pollution hot water coal-burning boiler using in the life, why black smoke is billowing for these boilers, exactly because the cause that coal is not fully burned in burner hearth, a large amount of flue gases and fuel gas are discharged and over-emitting black exhaust from chimney, and this will reduce the thermal efficiency with just being difficult to be avoided and cause environmental pollution.

The utility model content: task of the present utility model is at the problems referred to above, and a kind of clean cigarette coal-burning boiler is provided, and this boiler does not almost have black smoke in combustion process, and is not only free from environmental pollution but also can improve the thermal efficiency of boiler.Technical solution of the present utility model is: a kind of clean cigarette coal-burning boiler, comprise the combustion chamber and ash chamber, water jacket furnace, chimney, cleaning door and the air-introduced machine etc. that are divided into by the water flowing fire grate, it is characterized in that: said combustion chamber and ash chamber have two respectively, wherein, first combustion chamber and second combustion chamber are communicated with, first ash chamber and second ash chamber separate with partition wall, second ash chamber is communicated with chimney, the chimney diameter is up-small and down-big stepped, and this top, external second combustion chamber is provided with the air inlet adjustment mouth.Compared with prior art, advantage of the present utility model is: be provided with because its two combustion chambers are communicated with, second combustion chamber not only grate area is big, and has air-introduced machine and air inlet adjustment mouth to make oxygen supply, therefore forms high temperature very hot oven layer on the fire grate of second combustion chamber.And the flue gas of two combustion chamber generations must pass through this high temperature very hot oven layer simultaneously, make the flue gas forced burning, so, still do not have clean-burning flue gas in the burner hearth in leading to the process of chimney, just be able to abundant burning through the high temperature very hot oven layer of second combustion chamber.Facts have proved, this boiler in combustion process, the first combustion chamber forward combustion, flare upwards, the second combustion chamber reverse burning, flare is downward.If watch from second ash chamber, in most cases all be that blue flare jumps on chimney below the second combustion chamber fire grate, the up-small and down-big stepped setting of chimney diameter can make soot dust granule fall again in addition, therefore in the chimney outlet, almost can't see flue dust.The actual smoke situation of root a tree name judges that the utility model can convert the black smoke more than 90% to heat energy.Therefore say not only non-environmental-pollution of the utility model, but also can improve the thermal efficiency of boiler.Have advantages such as simple in structure, easy and simple to handle, with low cost simultaneously, suitable for large area applications.

Description of drawings: Fig. 1 is a structural representation of the present utility model.

The specific embodiment: as shown in Figure 1, the clean cigarette coal-burning boiler that the utility model provides, comprise the upper combustion chamber and following ash chamber, water jacket furnace, chimney, cleaning door and the air-introduced machine etc. that are divided into by the water flowing fire grate, it is characterized in that: said combustion chamber and ash chamber are respectively equipped with two, i.e. first combustion chamber and first ash chamber that is split to form by first fire grate 4; Second combustion chamber and second ash chamber that are split to form by second fire grate 3.Wherein first combustion chamber and second combustion chamber are communicated with, first ash chamber and second ash chamber separate by partition wall 5, make win cleaning door 6 and second cleaning door 1 opposing and establish, have only second ash chamber to be communicated with chimney 2 here, the diameter of chimney 2 is up-small and down-big stepped.In addition, in order to guarantee the very hot oven state of second combustion chamber, the area ratio with second fire grate 3 and first fire grate 4 is designed to 3: 2 here, and is provided with air inlet adjustment mouth 8 above second combustion chamber, to guarantee that enough burning areas and sufficient oxygen supply are arranged.The arrow indication is the traffic direction of flue gas among the figure.
