Abstract

The utility model relates to a combustion apparatus for a continuous gasified coal-fired boiler. The utility model is characterized in that supporting idlers are fixed on the base of a grate, the tabular grate falls on the supporting idlers, an air supply pipeline is arranged in the base under the grate, and a blast cap is upwardly arranged on the air supply pipeline; a plurality of slag toggling plates are fixed on the grate, a deslagging gap is arranged between the edge of the grate and the wall surface of the base, and the end of the grate is fixed with a push-and-pull rod. When the utility model works, the grate can do reciprocating movements manually or through a mechanism apparatus; deslagging can be manually controlled, so that coal can stay for a longer time in a combustion chamber, the coal can be combusted sufficiently, and the loss of combustion can be lower than 8%, the original discharge concentration of smoke dust can be lower than 150 mg/m<2>, the blackness of smoke gas can be lower than 1, and the effect of environmental protection can be outstanding.

Description

Continuous gasification coal-burning boiler burner

The utility model belongs to boiler combustion device.

Fire grate is the burner of coal-burning boiler widespread usage, adopt the boiler air of fire grate to blast fire grate bottom air compartment by air blast, pass the coal supply burning of fire grate gap, the slag that the burning back forms pushes in the ashcan by fire grate, common grate firing fire grate unburned carbon loss is about 10%, even bigger, the original dust exhausting concentration of boiler is very big simultaneously.

The purpose of this utility model is to provide the coal-burning boiler burner of a kind of sufficient combustion, good environmental protection, energy savings.

The purpose of this utility model realizes by technical scheme shown in the drawings, it comprises a fire grate and base, on base 7, be fixed with idler pulley 5, tabular fire grate 4 drops on the idler pulley, under the fire grate air supply line 6 is arranged in the base, air supply line upwards is equipped with blast cap 3, the elongated hole 8 that blast cap passes on the fire grate is higher than stoker surface, blast cap is a cavity, its side and end face have the bar shaped exhaust vent, stove is counted affixed polylith in and is dialled slag plate 2, leaves the slagging-off gap between fire grate edge and base wall, and the fire grate termination is connected with pull bar 1.

Lime-ash evenly is paved with whole fire grate, arranges ignition substance on it, coal is filled it up with vaporizer, coal through super-dry, destructive distillation, reduction-oxidation, burn.Fuel gas that produces and hot flue gas enter the secondary combustion chamber burning.Can fire grate be moved reciprocatingly by manual or mechanical device during the utility model work, cinder be promoted to be removed by the gray moving plate.Owing to adopt artificial control slagging-off, so fire coal can stop the long period in the combustion chamber, it is fully burnt, unburned carbon loss is lower than 8%, and energy-saving effect is obvious; Can make the original discharge concentration of flue dust be lower than 150 milligrams every square metre, blackness of exhaustion is less than 1, and environment protecting is outstanding.

Accompanying drawing 1 is the utility model front view;

Accompanying drawing 2 is an accompanying drawing 1A-A profile;

Accompanying drawing 3 is the utility model side view.
