Description

Burn the fume and dust coal-fired combusting device

The utility model relates to the coal stove technical field, belongs to a kind of burning fume and dust coal-fired combusting device that is used in the stove and accessory.

At present, various vertical boilers, tea-bath furnace, civil stove etc., it is insufficient that ubiquity burning, and over-emitting black exhaust, the shortcoming that dust is big are though there are various improved stove and accessorys, but not from basic elimination black smoke and dust, its reason is that coal-fired also not being fully burned in burner hearth just discharged with chimney, causes black particle and dust to enter atmosphere, has polluted air and environment, life to people causes very big harm, makes people suffer from various diseases easily.

The purpose of this utility model provides a kind of simple in structure, easy to use, burning fume and dust obvious results coal-fired combusting device.

For achieving the above object, the utility model is taked following design: a kind of burning fume and dust coal-fired combusting device, be arranged on the fire grate top at rear portion in the burner hearth, it is characterized in that: be provided with an interior cover that communicates up and down, be socketed with the overcoat that leaves interlayer at outside of inner cover, the upper and lower end parts of cover, overcoat is sealed mutually in being somebody's turn to do, and is connected with the airduct that communicates with interlayer in the both sides of overcoat, and the inwall of interior cover is provided with pore; On the sidewall of interior cover, also be provided with pore.

The utility model is described in further detail below in conjunction with accompanying drawing.
