The utility model has simple structure; low cost, high heat efficiency and broad application.

Description

A kind of civil boiler

The utility model belongs to a kind of civil boiler, include the combustion chamber (1), fire grate (2), and flue (3), have air door (4) in fire grate (2) bottom.

Have a kind of domestic energy-saving boiling water adopt dim boiler, its basic comprising be equipped with at a columnar central body of heater that fire grate, its top are provided with that combustion-supporting, this combustion-supporting are rearranged by the plurality of vertical pipe, all vertical tubes are equipped with air vent, two ends are inserted in fixing in the symmetrical iron plate hole, outer rim with the inboard wall of burner hearth welding, when the flame rising enters combustion-supporting, the air vent secondary air is combustion-supporting, makes full combustion of fuel.Though the civil boiler of this structure is combustion-supporting by combustion-supporting.But fuel still can not fully burn, thermal loss is big, the thermal efficiency is low and combustion-supporting very easily burns out, and dust can not get controlling, causing easily air pollution simultaneously.

The purpose of this utility model be to avoid above-mentioned prior art weak point, the civil boiler that a kind of fuel combustion is abundant, the thermal efficiency is high, the scope of application is wide, free from environmental pollution is provided.This boiler structure is simple, with low cost, production, installation, easy to use.

The purpose of this utility model can reach by following measure: thus the empty face that is provided with on the outer wall that many oxygen supply passages, this passage upper end closed, the sub-air door of lower ending opening, remainder are welded on the combustion chamber around the outer wall of combustion chamber, passage and outer wall of combustion chamber fasten be provided with air vent form except that fire grate through many oxygen supply passages the common oxygen supply channel in coal seam, make full combustion of fuel.

The purpose of this utility model also can be expressed by following measure: the combustion chamber stop through a minute fire lid to flue is interlayer, forms water jacket, the lower end of flue has " recessed " shape dust collecting trough, Fen Huogai is arranged on the combustion chamber top, combustion flame pour into dust collecting trough, increased heating surface area, floating dust falls in the dust collecting trough simultaneously.Said branch fire lid is that a flat board, bottom have support.

The utility model compared with prior art has energy-conservation, thermal efficiency height, free from environmental pollution, easy to install, advantages such as multi-use, particularly because the setting up of many oxygen supply passages, directly act on scorching hot flame part, all burn the not clean-burning carbon granule that rises with hot-air with because of fuel gas such as insufficient formed carbon monoxide that burns, form carbon dioxide, emit a large amount of heat simultaneously, improved the thermal efficiency, eliminate the black smoke in the waste gas, dust after the burning is also because the effect of oxygen supply passage, drop on the inboard of furnace bottom, can not overflow and pollute indoor from air door, the part floating dust is drawn onto the combustion chamber, falls within the dust collecting trough.

Accompanying drawing and drawing are described as follows:

Fig. 1 is the utility model stereochemical structure profile

Fig. 2 is the utility model profile

Fig. 3 divides fire lid structural representation for the utility model

Below in conjunction with accompanying drawing the utility model is done further commentary:

Add many oxygen supply passages (5) around the outer wall of (1) in the combustion chamber with reference to Fig. 1, Fig. 2, this passage is the semicircle pipe, upper end closed, lower ending opening are welded on the outer wall of combustion chamber (1) in air door (4) remainder, on the empty face of semicircle pipe and combustion chamber (1) outer wall fastening, preset air vent (6), thereby formed many oxygen supply passages (5) except that fire grate (2) sees through the common oxygen supply channel in coal seam, made full combustion of fuel; Many oxygen supply passages (5) are provided with 2 at least.

Combustion chamber (1) is interlayer to flue (3), and the centre is full of water formation water jacket (10), water flows into fin from delivery port (8) and flows back to water jacket (10) from water return outlet (9) again.

The lower end of flue (3) has " recessed " shape dust collecting trough (7).On the one hand floating dust can be fallen in the dust collecting trough, flame stops contact area from hot-air to dust collecting trough (7) that impacted, increased water jacket (10) and through a minute fire lid on the other hand, time expand, has improved the thermal efficiency.

With reference to Fig. 3, Fen Huogai (11) is a flat board, and the bottom is welded with support (12) and is placed on top, combustion chamber (1).Prevented that flame from flinging bell on the one hand, caused thermal loss and smolder, effectively flame has been kept off to dust collecting trough (7), improves the thermal efficiency on the other hand.When this stove of needs is used for other purposes, take out divides fire lid (11) to remove bell and put corresponding cooker and get final product.

Claims (5)

1, a kind of civil boiler, has combustion chamber (1), fire grate (2) and flue (3) are provided with air door (4), it is characterized in that in the lower end of fire grate (2): the empty face that is provided with many oxygen supply passages (5), passage (5) and combustion chamber (1) outer wall fastening around the outer wall of combustion chamber (1) presets air vent (6).

2, civil boiler according to claim 1, it is characterized in that: said many oxygen supply passages (5) upper end closed, lower ending opening is weldingly fixed on the outer wall of combustion chamber (1) in air door, remainder.

3, civil boiler according to claim 1 is characterized in that: the lower end of flue (3) also has " recessed " shape dust collecting trough (7).

4, according to claim 1 or 3 described civil boilers, it is characterized in that: Fen Huogai (11) is arranged on the top of combustion chamber (1), and combustion flame stops through a minute fire lid (11) pours into dust collecting trough (7).

5, civil boiler according to claim 4 is characterized in that: Fen Huogai (11) is a flat board, and the bottom is fixed with support (12).
