Technical field
The utility model belongs to the Industrial Boiler field, relates to specifically a kind of combusting coal water slurry CFBB.
Background technology
The combusting coal water slurry CFBB is to burn take water-coal-slurry or coal slime as fuel, for boiler provides heat.Publication number is CN201193819, name is called the Chinese patent literature of boiler for burning coal slurry, discloses a kind of boiler for burning coal slurry, and it comprises that combustion chamber, air distribution plate and water-coal-slurry splash into pipe, fuel splashes into pipe through water-coal-slurry and sows in the combustion chamber, burns under the effect of air distribution plate.Through burning, produce a large amount of flue gases in the combustion chamber, flue gas is discharged through flue.In fact, fuel is difficult to after-flame in burner hearth, contain a large amount of not combustion particles in the flue gas of its formation, and remaining particle follows flue gas to discharge together the combustion chamber, makes cool water mixture burning insufficient, not only causes energy waste and pollutant atmosphere.
The utility model content
The technical problem that the utility model solves is that a kind of clean-burning combusting coal water slurry CFBB of water-coal-slurry that makes is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of combusting coal water slurry CFBB, comprise burner hearth, fluid bed and dispenser, wherein, dispenser is arranged on the furnace wall of burner hearth, fluid bed is arranged in the bottom of burner hearth, also comprise flue gas separation unit, the one end is communicated with the furnace exhaust mouth, and the other end is communicated with burner hearth bottom;
Compared to the prior art, flue gas separation unit is installed in exhaust opening outlet at burner hearth, the flue gas of discharging is separated, unburned particle is spun off from flue gas, under the effect of material returning device, reenter burner hearth and burn again, until fuel particle fully burns, improve efficiency of combustion, avoided environmental pollution.
Described flue gas separation unit is comprised of spiral case cyclone separator and material returning device, and material returning device is arranged on the afterbody of spiral case cyclone separator; Flue gas separation unit adopts the spiral case cyclone separator, and separating effect is better, and at the tail end of spiral case cyclone separator, material returning device is installed, and makes the fuel particle of separating enter smoothly burner hearth.
The material returning device bottom is provided with the air port; The air port be communicated with to wind apparatus, make the fuel particle stable and continuous return to burner hearth.
Also comprise back-end surfaces, it is communicated with flue gas separation unit; Back-end surfaces further reclaims flue gas heat, and is arranged on the flue gas separation unit back, and like this, the particle in flue gas reduces, and reduces the wearing and tearing to back-end surfaces, extends its service life.
Burner hearth and flue gas separation unit flexibly connect; Burner hearth and flue gas separation unit are selected to flexibly connect, and make to form certain free degree between the two, avoid producing because relatively moving between the two tearing.
Also be provided with the pattern water-cooling wall, the heating surface of this fin panel casing is arranged in burner hearth inside, is positioned at the water-coal-slurry cluster of grains zone of operation downwards; Fin panel casing is subjected to thermal effect better, and its heating surface is arranged on the zone that the water-coal-slurry cluster of grains moves downwards, and granule density is high herein, but flowing velocity is slow, has strengthened heat transfer, avoids the wearing and tearing of water screen tube.
Dispenser is arranged on top or the top of burner hearth, and coordinates with totally-enclosed pumping installations; Dispenser is arranged on the top of burner hearth or top and makes and sow fuel and be easy to control, and effect is better, adopts totally-enclosed pumping installations supply, realizes any adjustment of fuel inlet pressure and flow.
Back-end surfaces adopts to prop up and hangs structure, and spiral case cyclone separator and material returning device also adopt to prop up and hang structure; Simple in structure, be easy to install and control.
Fin panel casing adopts suspension type; Simple in structure, be easy to fixing and install.
