Description

Wood chip, assorted bavin, coal multipurpose efficient boiler

The utility model relates to and a kind ofly is used to drink water, steamed rice, have a bath, the boiler of purposes such as heating.

The used fuel of existing boiler is single, or special-purpose coal, firewood are coal-burning boiler as fuel, or special-purpose wood chip is firebrand bits boilers as fuel, and they can not be used with, and are higher to demanded fuel, so use face is restricted.In addition, the burner hearth and the flue of existing boiler are an integral body, and it exists the thermal efficiency and the low shortcoming of intensity.

The purpose of this utility model is exactly in order to address the above problem, and a kind of wood chip, assorted bavin, coal multipurpose efficient boiler are provided, and it can make fuel with any material that can burn, and application surface increases greatly.

Technical solution of the present utility model is as follows:

A kind of wood chip, assorted bavin, coal multipurpose efficient boiler, it is made up of housing (1), flue (2) and impact tube (3) thereof, burner hearth (4), the row of protecting (5), have the fire door (6) that communicates with burner hearth (4) in housing (1) bottom and observe door (7), the position that it is characterized in that corresponding fire door (6) one sides in housing (1) bottom has inlet scoop (8), near this inlet scoop (8) top, in housing (1) burner hearth (4), be provided with one group of fire grate (5), this group fire grate (5) is a water pipe furnace grate, and they are communicated with housing (1) inner chamber.

The waterpipe type fire grate structure that the utility model adopts the furnace bottom inlet scoop and closely is abutted against, there are enough air intakes to guarantee burning when making fuel combustion, no matter adopt which kind of fuel all can fully burn, as wood chip, assorted bavin, cage chaff, waste and old broken plastics, onal leather, cloth waste and coal etc., all can use, use face increases greatly, and people can suit measures to local conditions to adopt fuel separately to burn.The utility model is simple in structure, economic security, and long service life, heat conduction is fast, gas forming amount is big, the operation simple and convenient, thermal efficiency height can reach more than 75%.Can satisfy that unit drinks water, steamed rice, have a bath, demand such as heating, also be suitable for coating factory simultaneously, Bean Products Factory produces and aspects such as high-temperature sterilization are used.

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

As shown in Figure 1, when the utility model uses, water is injected the inner chamber of housing (1), place more than 2/3 to the body of heater height, again with fuel, no matter be coal, wood chip, firewood, or cage chaff, waste and old broken plastics, the onal leather, all combustible foreign material such as cloth waste, all join on the interior water pipe furnace grate (5) of burner hearth (4) from fire door (6), can burn, because there is inlet scoop (8) the body of heater bottom, can guarantee that sufficient air intake makes various full combustion of fuel, the heat of burning enters flue (2) by standpipe (9), and standpipe (9) is positioned between burner hearth (4) and the flue (2), they are communicated with connect, the radical of the radical of standpipe (9) and fire grate (5) is all determined according to the size of boiler.Standpipe (9) has increased the heat exchange area of water on the one hand, improves the thermal efficiency and reaches more than 75%, has increased the intensity of flue (2) on the other hand again, and is especially more suitable to aluminium boiler using.The heat of burner hearth (4) reaches the further interior water of heated shell (1) of flue (2) back, fire grate (5) is a waterpipe type in addition, and then water carries out circulation from fire grate (5), has improved the rate of heat exchange of water again, confess required steam and hot water at last, result of use is very desirable.Observing door (7) is to be used for observing combustion flame, with the burning of control fuel.

Claims (2)

1, a kind of wood chip, assorted bavin, coal multipurpose efficient boiler, it is made up of housing (1), flue (2) and impact tube (3) thereof, burner hearth (4), fire grate (5), have the fire door (6) that communicates with burner hearth (4) in housing (1) bottom and observe door (7), the position that it is characterized in that corresponding fire door (6) one sides in housing (1) bottom has inlet scoop (8), near this inlet scoop (8) top, in housing (1) burner hearth (4), be provided with one group of fire grate (5), this group fire grate (5) is a water pipe furnace grate, and they are communicated with housing (1) inner chamber.

2, wood chip according to claim 1, assorted bavin, coal multipurpose efficient boiler is characterized in that burner hearth (4) upper end is connected with flue (2) by many standpipes (9).
