Abstract

The utility model relates to a civil water heating boiler combustion device, comprising a main combustion chamber 2, a sub combustion chamber 3, a passage 4 between the main combustion chamber and combustion chamber, a fire grate 5 and a product slag box 1. The upper end of the main combustion chamber is provided with a door used for ventilating and adding coal. The main combustion chamber comprises a fire layer and a spare coal layer. The spare coal layer obtains preheating and burns second times in the sub combustion chamber. The utility model has the advantages of completeness of combustion, high thermal efficiency and good effect on eliminating smoke and dust.

Description

Novel smoke abatement and dust control burner

The utility model relates to a kind of civilian unpressurized hot water boiler's burner.

Traditional vertical unpressurized hot water boiler's burner is made up of fire grate, fire door, combustion chamber, several parts of chimney, and coal enters the combustion chamber from fire door, and the air port air intake under fire grate is combustion-supporting, and flue gas enters atmosphere from chimney.This boiler is because fuel can not fully burn, and chimney exit black smoke is billowing, and dust is big, the thermal efficiency is also low.

The boiler combustion device that the purpose of this utility model is to provide a kind of can fully burn, smoke medicining dust-removing effect is good.

The utility model is achieved in that

This burner is made up of combustion chamber, fire grate, slag box, several parts of chimney, main two combustion chambers of paying are divided in its combustion chamber, there is fire door the main chamber upper end, play coal and gravity-flow ventilation, fire grate is arranged below the main chamber, fire grate bottom is a slag box, in the side of main chamber one exhaust gases passes is arranged, be communicated with and paying the combustion chamber, paying the combustion chamber bottom side and have cleaning door, chimney is located at the top of paying the combustion chamber.

During work, coal adds from the fire door of main chamber upper end, forms burning zone near the main chamber fire grate, is to be equipped with the coal seam on burning zone, in main chamber, is equipped with the coal seam and is given heat.Under the wind action of upper furnace door nature, the pyrotechnics of main chamber enters and pays the combustion chamber by the main passage of paying between the combustion chamber, and after the second-time burning, flue gas is discharged from chimney.

The reverse burning of the utility model main chamber is equipped with coal and gives heat, and flue gas can fully burn in a pair combustion chamber.Therefore, thermal efficiency height, smoke medicining dust-removing effect is good.

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

Accompanying drawing 1 is novel smoke abatement and dust control burner schematic diagram;

As shown in the figure, this burner is made up of main chamber 2, pair combustion chamber 3, main passage 4 and the chimney of paying between the combustion chamber 6, establish fire door in the main chamber upper end, play the effect of coal air feed, be to be slag box 1 below fire grate 5, the fire grate below the main chamber, paying the combustion chamber bottom side has a cleaning door 7, and side wall of combustion chamber is a tank outer wall.During this combustion system work, coal adds from the fire door of main chamber 2 upper ends, and under the wind action of fire door nature, near the coal the fire grate forms burning zone in burning, forms at the coal near the fire door part to be equipped with the coal seam, is given heat.Pyrotechnics enters by the main passage of paying between the combustion chamber 4 and pays the combustion chamber, and after the second-time burning, flue gas is discharged from chimney 6.

Claims

1, a kind of New-type boiler smoke abatement and dust control burner, form by combustion chamber, fire grate, slag box, several parts of chimney, it is characterized in that the combustion chamber branch is main, pay two combustion chambers, there is fire door the main chamber upper end, be fire grate below, fire grate bottom is a slag box, has an exhaust gases passes being communicated with in the side of main chamber and pays the combustion chamber, pay the combustion chamber bottom side and establish cleaning door, chimney is located at pays top, combustion chamber.
