Abstract
The utility model provides a boiler using furfural as fuel. A fuel feed opening (6) is arranged on the upper part of a combustion chamber (9). An air inlet duct (7) for overheat blast is arranged on one side of the upper part of the fuel feed opening. Another air inlet duct (8) for overheat blast is arranged on the furnace body which is on the lower part of the fuel feed opening. The combustion chamber (9) is provided with an after arch upper plate (2) which is lengthened. The utility model has the advantages that he boiler can realize that the furfural is totally used as fuel, and burn efficiently with good result of producing steam. The amount of steam produced not only can meet the needs in the process of furfural production, but also provide surplus overheat steam for a steam turbine to generate electricity that is used for the furfural production, which considerably reduce the furfural production cost. The residue of the furfural can be completely digested, which realizes comprehensive utilization, and does not occupy land or pollute environment.
Description
Technical field
The utility model provides a kind of boiler, especially a kind of steam boiler.
Background technology
Present boiler is a fuel with coal, oil generally, the production cost height, and consume non-renewable energy resources.And be the furfural factory of raw materials for production with the corncob, a large amount of outputs are extracted the furfural dregs behind the furfurals.These furfural dregs are deposited on the ground, have not only taken valuable land resource, and have caused the serious environmental pollution.Someone once considered with furfural dregs as boiler oil.But the difficulty because the furfural dregs moisture content up to about 50%, burns can only partly be spiked in the coal, and addition content is about 40%.And because of the furfural dregs fuel value is lower, having produced harmful effect to steaming, influenced steam production, only is about 50% of its nominal output.
Summary of the invention
Technical problem to be solved in the utility model is, providing a kind of is the boiler of fuel with the furfural dregs, and it is fuel fully with the furfural dregs, to reduce production costs, alleviates the pollution that furfural dregs causes.
The utility model is to realize like this, a kind of is the boiler of fuel with the furfural dregs, comprise body of heater, water inlet and venthole are arranged on the body of heater, combuster and flue in the body of heater, fire grate is arranged at the body of heater bottom, it also has fuel feed inlet, and described fuel feed inlet is positioned at the top of combustion chamber, and fuel feed inlet top one side had hot-air inlet pipe, have another to cross hot-air inlet pipe on the body of heater of fuel feed inlet bottom, described combustion chamber has the rear arch upper plate of lengthening.
Adopting a kind of of said structure is the boiler of fuel with the furfural dregs, can realize being fuel fully with the furfural dregs, and sufficient combustion, it is effective to steam, the quantity of steam that produces can not only satisfy the demand of furfural production process, and also have superheated steam steam supply turbine generating more than needed, be used for furfural production, thereby reduced the furfural production cost significantly, furfural dregs can be digested fully, realized comprehensive utilization, land occupation and cause environmental pollution no longer, environmental benefit is remarkable.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and operation principle.
As shown in drawings, the a kind of of the utility model is the boiler of fuel with the furfural dregs, comprise body of heater (3), water inlet (1) and venthole (4) are arranged on the body of heater, combuster (9) and flue (5) in the body of heater, fire grate (10) is arranged at the body of heater bottom, it also has fuel feed inlet (6), described fuel feed inlet (6) is positioned at the top of combustion chamber (9), fuel feed inlet top one side had hot-air inlet pipe (7), have another to cross hot-air inlet pipe (8) on the body of heater of fuel feed inlet bottom, described combustion chamber (9) have the rear arch upper plate (2) of lengthening.
Fuel feed inlet (6) is located at top, combustion chamber, and the charging aperture that has changed existing coal-burning boiler is located at the structure of bottom of furnace body one side, makes the higher furfural dregs of moisture content fall on the fire grate in the bags, and the moisture in the furfural dregs is heated evaporation.The hot blast of crossing of crossing the interior ejection of hot-air inlet pipe (7) of fuel feed inlet top one side blows to the furfural dregs that falls in the fuel feed inlet, and its moisture content is reduced to about 42% by about 50%.Another of fuel feed inlet bottom crossed the hot blast of crossing of hot-air inlet pipe (8) ejection, blow to the furfural dregs that falls in the combustion chamber, make its whereabouts track be parabola shaped, fall more equably, but vertically drop on the fire grate, add blowing that fire grate bottom air intake makes progress, the time that makes furfural dregs fall prolongs greatly, form suspended state, under the condition of combustion chamber Nei Gaore, the part in the furfural dregs is just burnt in dropping process, forms " chamber combustion ", another part drops down onto on the fire grate and burns, and forms " grate firing ".Can increase amount of radiation behind rear arch upper plate (2) lengthening of combustion chamber, the also corresponding lengthening of fire grate, the endotherm area of expansion water behind the combustion chamber rear arch lengthening, drops on the distance lengthening that the furfural dregs on the fire grate moves in the combustion chamber, and extend burning time, and it is more abundant to burn.Angle on the comparable former coal-burning boiler of the angle of rear arch upper plate and horizontal plane reduces, with further prolongation suspension time.
Like this, the higher furfural dregs of moisture content is after crossing the drying up of hot blast, the oven dry of combustion chamber inner suspension, and moisture content significantly reduces, burning condition is good, and " chamber combustion " takes place part, and " grate firing " takes place another part, sufficient combustion is heated into steam with the water in the body of heater, for using in the furfural production process.Because burning condition is good, the temperature in first corner that flue gas rises can reach about 960 ℃, so just can produce superheated steam, drives steam turbine power generation, uses for furfural production.
Claims (1)
1, a kind of is the boiler of fuel with the furfural dregs, comprise body of heater (3), water inlet (1) and venthole (4) are arranged on the body of heater, combuster (9) and flue (5) in the body of heater, fire grate (10) is arranged at the body of heater bottom, it also has fuel feed inlet (6), it is characterized in that, described fuel feed inlet (6) is positioned at the top of combustion chamber (9), fuel feed inlet top one side had hot-air inlet pipe (7), have another to cross hot-air inlet pipe (8) on the body of heater of fuel feed inlet bottom, described combustion chamber (9) have the rear arch upper plate (2) of lengthening.
