Coal-saving temperature-control sealing fire device for briquette boiler

Abstract

The invention relates to a coal-saving temperature-controlling fire seal for briquette boilers, which comprises a rectangular plate-like body (1) made of high temperature-resistant cast iron, a lifting ring (12) is arranged at the center of a top plate (11) of the body (1), a plurality of vertical reinforcing ribs (15) are downwardly arranged crisscross on a bottom plate (13) of the body (1), and a plurality of air-regulating doors (2) which respectively cooperate with each fire-sealing regulation air hole (16) and can adjust the opening degrees of the fire-sealing regulation air holes (16) are arranged on the body (1). The usage of the coal-saving temperature-controlling fire seal for briquette boilers can effectively control the burning speed and fire power of briquettes, and can control temperature to seal fire when temperature requirement is reached. During controlled slow burning and fire sealing, flammable gas can sufficiently burn, and harmful gas cannot be produced, so green emission is realized. Fire cannot go out, and fire still can be sealed when the hot water in the boiler cannot circulate due to power outage, water outage or water pump failure, so that safety accidents cannot be caused.

Description

technical field [0001] The invention relates to a boiler, in particular to a coal-saving temperature-control sealing fire device for a coal-shaped boiler. Background technique [0002] The use and combustion method of the briquette boiler is to place the briquette coal (honeycomb coal) neatly and layered on the grate on the front platform of the boiler, and push each grate to the track in the furnace row by row by the coal pusher. After the furnace is fully pushed, fire is ignited on the grate at the rear of the furnace. The fire burns upwards from the multiple honeycomb holes of the briquettes, and burns from back to front one by one. The grate is pushed into the furnace from the front of the boiler, while the spent grate at the rear is pushed out of the furnace. [0003] At present, there are the following common combustion problems in briquette boilers at home and abroad: [0004] 1. The briquette boiler cannot effectively control the combustion speed and firepower of t...

AI Technical Summary

Problems solved by technology

[0004] 1. The briquette boiler cannot effectively control the combustion speed and firepower of the briquette

[0005] 2. After the briquette is burned, it is impossible to control the sealing of the fire, causing the room temperature to be uncontrollable when it meets the requirements, that is, a large amount of coal is wasted, and the room temperature will be too high

If it is controlled by closing the smoke outlet, black smoke and harmful gases will be formed due to insufficient combustion, which will pollute the air after being discharged

If the soot leaks, it will also cause soot poisoning

[0006] 3. If the briquette is not added in time, the furnace fire will be burnt out and extinguished, causing the indoor temperature to drop, seriously affecting normal production, work and life, and re-igniting will waste time, energy and material resources. At the same time, wasting kindling will also waste more heat energy

[0007] 4. In case of power failure or failure, the water pump cannot circulate the hot water in the boiler, and the combustion cannot be controlled automatically, which will cause the boiler water temperature to rise and generate gas, and the boiler will be over-pressurized to cause danger and cause a safety accident
