Abstract

The utility model discloses a mould coal boiler, comprising an air intake of the furnace chamber, characterized in that: bottom of the furnace chamber is closed; the air intake is formed of a through hole that passes through any side wall of the furnace chamber as well as the heat-insulating layer and the outer wrapper on the same side, and the air intake is intercommunicated with the air supply outlet of the blast equipment. Since the air intake is positioned on the side wall of the furnace chamber and runs through the heat-insulating layer and the outer wrapper on the same side, therefore when mould coal is sent into the furnace chamber and laid transversally, the utility model can ensure that the ventilation holes of the mould coal face the same direction as the air intake hole to obtain high combustion strength, fast combustion speed and high thermal efficiency; besides, the utility model has the advantages of: low cost and convenient to operate etc.

Description

A kind of molded coal boiler

The utility model relates to a kind of boiler, exactly is a kind of molded coal boiler.

Molded coal boiler promptly can be used as hot-water boiler, also can be used as steam boiler.The former can provide heating, bath water; The latter can provide production, life vapour.The design feature that existing molded coal boiler generally has is that the air feed direction from the bottom to top on the air feed mouth was positioned at the bottom of the thorax of burner hearth.The handling characteristics that this design feature is brought for it is that moulded coal must be placed in the burner hearth, and is consistent with boiler air feed direction to keep its air vent direction.In addition, the burning direction of moulded coal is from top to bottom.Because the moulded coal burning direction of this boiler is opposite with its air feed direction, thereby have unavoidably that combustion intensity is low, speed is slow, the defective that the thermal efficiency is not high.At present, people overcome this defective and the technical measures that generally adopt are to increase combustion chamber volume, and very cause a plurality of combustion chambers are set, so that the existing following problem of boiler ubiquity: 1, volume is excessive, thereby improving product manufactures cost and transportation mounting cost; 2, boiler body is difficult for the vertically-arranged setting, thereby brings the difficulty that is difficult to overcome for designing steam boiler; When 3, a plurality of combustion chamber being set, operation is more loaded down with trivial details, has increased fireman's labour intensity.

The purpose of this utility model is to make the moulded coal burning direction molded coal boiler consistent with its air feed direction for people provide a kind of, so that overcome the problems referred to above that prior art exists.

The purpose of this utility model is to realize like this, it comprises burner hearth air feed mouth, the thorax underseal that is characterized in burner hearth closes, and described air feed mouth is made of the through hole that passes the arbitrary side wall of burner hearth and this side heat-insulation layer, exoperidium, and this air feed mouth is communicated with the exhaust outlet of blast apparatus.

After the utility model is realized,, therefore, in use, when the user adds moulded coal in burner hearth, just make moulded coal horizontal naturally because the air feed mouth is arranged on burner hearth side wall and this side heat-insulation layer, the exoperidium, consistent to guarantee its air vent direction with the air feed direction.Like this, as long as make the seed region of moulded coal in the burner hearth be positioned at its air feed mouth one side, just can make air feed direction of the present utility model consistent with the moulded coal burning direction, thereby make it to have the combustion intensity height, speed is fast, the premium properties that the thermal efficiency is high, and then bring following advantage: 1, can obviously reduce combustion space, and then reduce boiler volume.Like this, can reduce product on the one hand and manufacture cost and transportation mounting cost, also provide the condition that makes things convenient on the other hand for manufacturing and designing steam boiler; 2, the utility model needn't be provided with a plurality of burner hearths, thereby operates more conveniently, has reduced fireman's labour intensity.

Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the A-A profile of Fig. 1.

As seen from the figure, the utility model comprises thorax top 16, burner hearth side wall, the i.e. forward and backward and left and right sides side wall 15 of burner hearth that the body of heater of prior art returns smoke-box 1, cleaning door 2, coal feeding hole 3, pushes away device for coal 4, base 5, instrument 6, exoperidium 7, outlet flue 8, heat-insulation layer 9, heat-insulation layer 10, cleaning door 11, air feed mouth, moulded coal pallet 17, burner hearth 13 and constitute this burner hearth.The utility model difference with the prior art is at the bottom of the thorax of burner hearth that 18 are closed, and the air feed mouth is made of the through hole 14 that passes burner hearth right-side wall and this side heat-

insulation layer

9,10 and exoperidium 7, and this air feed mouth is communicated with the air outlet of blast apparatus 12.The air feed mouth also can be made of the through hole that passes the forward and backward or left side wall of burner hearth and this side heat-

insulation layer

9,10, exoperidium 7 in actual production.In this case, as long as the air outlet of air blast is communicated with burner hearth air feed mouth, pushes away device for coal and be arranged on the relative side side wall with burner hearth air feed mouth, the utility model can use equally.

Using method of the present utility model is: earlier moulded coal is horizontally placed on each pallet, the pallet that will be loaded with moulded coal is again sent into burner hearth one by one and is made it propelling to the right in closed furnace by pushing away device for coal by coal feeding hole 3; Then, light rightmost side moulded coal, start air blast, make it, can keep moulded coal sustained combustion in the thorax by air feed mouth air feed in burner hearth; After a period of time, take out in cleaning door 11 burning to most rightmost side moulded coal and pallet thereof, continue coal by coal feeding hole again and make it to advance to the right by pushing away device for coal, so circulation moves boiler continuously.

Claims

1, a kind of molded coal boiler, it comprises burner hearth air feed mouth, it is characterized in that the thorax underseal of burner hearth closes, described air feed mouth is made of the through hole that passes the arbitrary side wall of burner hearth and this side heat-insulation layer, exoperidium, and this air feed mouth is communicated with the air outlet of blast apparatus.
