Abstract
The utility model discloses a boiler burning device using biomass fuels, which is characterized in that the boiler burning device comprises a revolving kiln preheating mechanism, a feeding mechanism, an air heating mechanism and a combustion furnace, wherein a storage chamber of the revolving kiln preheating mechanism is communicated with a hot hopper of the feeding mechanism, a horizontal conveyor belt of the feed mechanism is connected with an air duct hopper of the air heating mechanism, and an air duct of the air heating mechanism is communicated with a hearth of the combustion furnace. The boiler burning device using the biomass fuels has the advantages that the boiler burning device can use wastes, uses the wastes of agriculture and forestry as fuels, and has rapid firing, complete combustion, high combustion heat energy and less environmental pollution.
Description
Technical field
The utility model relates to a kind of combustion of industrial boiler device, particularly a kind of boiler combustion device that can use biomass fuel.
Background technology
Traditional Industrial Boiler is all made fuel with coal mostly, and coal can produce bigger pollution, and as dust, pernicious gases such as sulphur, nitrogen are disposable fossil fuel.With agricultural wastes, as bar, leaf, shell, quarrel etc. and forestry waste branch, leaf, skin, root particularly the wood powder quarrel after the sawmilling etc. all are good living beings alternative fuel, having burning and producing and pollute advantages such as little, renewable.But the use of this fuel is different with the burning coal, particularly substitutes burning in existing coal-fired pot, can have some problems.
The utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, and a kind of boiler combustion device that can use biomass fuel is provided.
The utility model is made up of rotary kiln preheating mechanism, feed mechanism, air heat mechanism and combustion furnace, the apotheca of rotary kiln preheating mechanism is communicated with the hot hopper of feed mechanism, the horizontal conveying belt of feed mechanism is connected with the airduct hopper of air heat mechanism, and the airduct of air heat mechanism is communicated with the burner hearth of combustion furnace.
Described rotary kiln preheating mechanism is made up of feed hopper, conveyer belt, rotary kiln, electric shift case, drying and burning stove and apotheca, conveyer belt is connected with feed hopper, feed hopper is connected with rotary kiln, the electric shift case is connected with rotary kiln, the drying and burning stove is communicated with rotary kiln, and rotary kiln is connected with apotheca.
Described feed mechanism is made up of horizontal conveying belt, hot hopper and hot hopper valve, and horizontal conveying belt is connected with the airduct hopper of hot hopper and air heat mechanism respectively.
Described air heat mechanism is made up of boiler afterheat device, airduct, airduct hopper and blower fan, and the airduct hopper is communicated with boiler afterheat device, airduct, blower fan and burner hearth.
The course of work of this boiler combustion device is: earlier the biomass fuel process is cut, saw, grind, mill etc. is machined into wood chip shape and meal shape etc., after carrying out air dry, send into the boiler internal combustion again after passing through the heated drying processing again and air mixing, conveyer belt is delivered to the hopper that places eminence with fuel by lower, enter rotary kiln, electric shift case driven rotary kiln is made low speed rotation, behind the heated drying combustion furnace burning fraction fuel, kilneye under the hot gas warp is entered in the rotary kiln, fuel enters apotheca and advances hot hopper again behind heated drying, there is wall to pull around the hot hopper, suitable for reading and the discharging end opening of charging is arranged respectively, the wall that the scraper-type valve is installed in hot hopper is pulled on the facade and can be made up-down adjustment, and fuel is sent among the airduct hopper through regulating and control to be located on the horizontal conveying belt again, air carries out preheating through the boiler afterheat energy-saving appliance and heats, send into blower fan by airduct again, through the airduct hopper, fuel is sprayed into the burner hearth burning after the air-flow mixing enters blower fan in the air-supply way.
The utility model has the advantages that: can twice laid, the discarded object of agricultural and forestry is acted as a fuel, to catch fire rapidly, burning is complete, the heat energy height of burning, environmental pollution is little.
