Abstract
The utility model relates to a counter heating boiler, which belongs to the technical field of solid fuel combustion apparatuses. The technical problem which needs to be solved is provided with a counter heating boiler which is completely burnt and is beneficial for environment. The technical proposal is that the counter heating boiler comprises a boiler casing and an internal furnace, wherein the internal furnace further comprises a fire tube, a hearth and a water-pipe fire grate, wherein the hearth is provided with a main air outlet and a secondary air outlet which are communicated with a blast tube, and the lower portion of the water-pipe fire grate is provided with an air distribution interface which is communicated with the blast tube. The counter heating boiler which is provided by the utility model is further provided with an air distribution interface under the fire grate of the existing counter heating boiler. The arrangement of the air distribution interface can obviously eliminate the phenomenon that a boiler emits black smoke on the steps of making a fire, adding coal and sealing fire, which is very beneficial for environmental protection. The counter heating boiler is a more idea combustion apparatuses.
Description
Technical field
The utility model relates to a kind of back firing boiler, belongs to the solid fuel ignition equipment technical field.
Background technology
Existing back firing boiler is made of furnace shell and flue, comprises again in the formation of flue that pyrotechnics pipe, burner hearth and water pipe furnace grate, burner hearth are provided with main air outlet and the auxiliary air outlet of being located at roof of the furnace.The auxiliary air outlet of this back firing boiler burner hearth is far away from the combustion zone in coal seam, and the air-supply approach is stopped by again in the coal seam, so its air-supply effect is undesirable, is prone to the over-emitting black exhaust phenomenon on the lighting a fire of boiler, stoking and three links of banking up a fire.Especially when boiler is fuel combustion with brown coal, insufficient because of burning, usually the phenomenon that tobacco follows black smoke to emerge from chimney can appear, and environmental pollution is comparatively serious, in view of this, should be improved.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sufficient combustion, environmental back firing boiler.
The technical scheme that solves the problems of the technologies described above is:
A kind of back firing boiler, its bag furnace shell, flue, flue comprises pyrotechnics pipe, burner hearth and water pipe furnace grate again, and burner hearth is provided with main air outlet and the auxiliary air outlet that is connected with ajutage, and said water pipe furnace grate bottom is provided with the air distribution interface that is communicated with ajutage.
Above-mentioned back firing boiler is provided with the adjusting valve door between said air distribution interface and ajutage, or is provided with adjusting valve between main air outlet and ajutage.
Above-mentioned back firing boiler is serially connected with shared air-supply distributor box between said main air outlet, air distribution interface and ajutage.
Above-mentioned back firing boiler, said air distribution interface are located at the following 30～100mm of water pipe furnace grate.
Back firing boiler provided by the utility model is to set up an air distribution interface under the fire grate of existing back firing boiler, can make the burning of fuel more abundant like this, not only can improve the thermal efficiency of boiler, also can save right material.The setting of air distribution interface can obviously eliminate boiler light a fire, the phenomenon of over-emitting black exhaust on stoking and three links of banking up a fire, be beneficial to very much environmental protection.This back firing boiler is a kind of comparatively ideal combustion apparatus.
Description of drawings
Fig. 1 is that the master of a kind of embodiment of the utility model looks and analyses and observe office and cut open structural representation;
