Abstract
The utility model discloses a combustion -supporting device of secondary air that boiler was used, the combustion air feeding device of setting outside boiler furnace, one end connection combustion air feeding device, the other end place the way of resistant high temperature tube in the furnace in, and the connection is placed the combustion air distributor of the resistant high temperature tube way one end in the furnace in and is connected the nozzle of combustion air distributor, the nozzle mouth arrange in the furnace. The utility model relates to a rationally, combustion -supporting effectual, make the combustion air intensive mixing of combustible substance that fuel appeared and high temperature, effectively make the combustible substance after -flame.
Description
Technical field
This utility model belongs to power economized boiler field, specifically refers to the secondary air combustion-supporting device of a kind of boiler with coal, biomass as fuel.
Background technology
Boiler is society heating and the visual plant produced, and main fuel is coal, biomass, oil, gas etc., in combustion due to a variety of causes, makes fuel gas not burn completely, causes white carbon black to enter air with flue gas.Inspection information and technology retrieval, for combustion-supporting secondary wind by many employings, also produce some good results, but due to low to the source temperature of wind, be directed at effect unsatisfactory.
Summary of the invention
The purpose of this utility model be provide to overcome the deficiencies in the prior art a kind of reasonable in design, combustion-supporting effect good, effectively promotes the secondary air combustion-supporting device of the boiler of combustible after-flame.
For achieving the above object, this utility model be the technical scheme is that the secondary air combustion-supporting device of a kind of boiler, include the combustion air feedway arranged outside boiler furnace, the high-temperature resistant pipeline that one end connects combustion air feedway, the other end is placed in burner hearth, connecting the combustion air allotter of the high-temperature resistant pipeline one end being placed in burner hearth and connect the nozzle of combustion air allotter, described jet hole is placed in burner hearth.
Further, described being placed in high-temperature resistant pipeline in burner hearth and be partially disposed in the top of burner hearth, its port is connected with the combustion air allotter being embedded in the forward and backward chimney arch of boiler.
Further, described being placed on the high-temperature resistant pipeline outside burner hearth is provided with regulation valve.
Owing to using said structure, combustion air supply arrangement through boiler peripheral hardware, connect the high-temperature resistant pipeline gradually heated in being embedded in the forward and backward chimney arch of boiler, by burner hearth the first backhaul high-temperature region, being heated rapidly to preferable air themperature for combustion-supporting auxiliary air, by the allotter in the forward and backward chimney arch being embedded in boiler, the high temperature air of heating is sprayed by the nozzle being installed on combustion air allotter.By the regulation valve being arranged on air line, according to the quantity delivered of hearth combustion regulating working conditions combustion air, make combustible that fuel separates out be sufficiently mixed with the combustion air of high temperature, effectively promote the after-flame of combustible.
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional structure schematic diagram.
Fig. 3 is enlarged drawing at the B of Fig. 1.
Fig. 4 is enlarged drawing at the C of Fig. 2.
Detailed description of the invention
The secondary air combustion-supporting device of a kind of boiler, is made up of combustion air feedway 1, regulation valve 6, high-temperature resistant pipeline 2, combustion air allotter 4 and nozzle 5.Combustion air feedway 1 arranges outside boiler furnace, the similar devices such as aerator can be used, on the high-temperature resistant pipeline 2 that regulation valve 6 is arranged on outside burner hearth, high-temperature resistant pipeline 2 one end connects combustion air feedway 1, the other end is placed in burner hearth and puts interior, the high-temperature resistant pipeline 2 being placed in burner hearth is partially disposed in the top of burner hearth, it is easy to heating, the port being placed in burner hearth respectively be embedded in boiler 7 before, combustion air allotter 4 in rear chimney arch 3 is connected, combustion air allotter 4 connects multiple nozzle 5, 5 mouthfuls of each nozzle is in burner hearth, the combustible separated out from the high temperature combustion air of nozzle 5 ejection and fuel is made to be sufficiently mixed, effectively promote the after-flame of combustible.
This utility model is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, these features and embodiment can carry out various change or equivalence is replaced.It addition, under teaching of the present utility model, can modify these features and embodiment to adapt to particular situation and material without departing from the spirit and scope of the present invention.Therefore, this utility model is not limited to the particular embodiment disclosed, and the embodiment in the range of fallen with claims hereof broadly falls into protection domain of the present utility model.
Claims (3)
