Abstract
The utility model relates to a modified coal-fired boiler, which can utilize biomass material of low price to replace coal, to realize two functions in one furnace, thereby saving investment and application cost, and saving energy. The coal-fired boiler comprises a coal-fired boiler system, which is characterized by further comprising a biomass gasifying combustion system connected with the coal-fired boiler system, wherein the biomass gasifying combustion system comprises a biomass gas burner, a biomass combustible gas channel and a biomass gasifying system which are connected in turn, the biomass gas burner is arranged in the hearth of the coal-fired boiler system.
Description
(1) technical field
The utility model relates to the steam generator system field, is specially a kind of coal-burning boiler of improvement.
(2) background technology
Common coal-burning boiler is a fuel with single coal, and coal is non-regenerative resource, and in today of energy scarcity, the rise of coal price causes the operating cost of coal-burning boiler also to go up thereupon.Owing to can only use coal, materials are single, must be equipped with corresponding boiler for different fuel, and user's acquisition cost strengthens.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of coal-burning boiler of improvement, and it can use different fuel, and adaptability is strong, has alleviated user's acquisition cost.
Its technical scheme is such: it comprises coal-burning boiler system, it is characterized in that: it also comprises the biomass fuel gasifying combustion system that a cover is connected with coal-burning boiler system, described biomass fuel gasifying combustion system comprises biomass gas burner, living beings combustible gas transfer passage, the biomass fuel gasifying system that is linked in sequence, and described biomass gas burner is installed on the burner hearth of described coal-burning boiler system.
It is further characterized in that: the biomass fuel gasifying system comprises biomass gasifying furnace, separator, the separation material-returning device that is linked in sequence, and the exhaust outlet of described separator is connected with described biomass combustible gas transfer passage.
After the utility model adopted said structure, it can be in biomass material abundant season, with the alternative coal fuel of biological material with low cost and save production cost.It can accomplish that a stove is dual-purpose, has both saved the purchasing of user, use cost, has saved the energy again.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model
(5) specific embodiment
See Fig. 1, the utility model comprises coal-burning boiler system 1 and biomass fuel gasifying combustion system, the biomass fuel gasifying combustion system comprises biomass gas burner 6, living beings combustible gas transfer passage 5, the biomass fuel gasifying system that is linked in sequence, burner 6 is installed on the burner hearth of coal-burning boiler system 1, the biomass fuel gasifying system comprises biomass gasifying furnace 2, separator 3, the material-returning device 4 that is linked in sequence, and the exhaust outlet of separator 4 is connected with biomass combustible gas transfer passage 5.7 is economizer among Fig. 1, and 8 is deduster, and 9 is coal-fired charging aperture, and 10 is the living beings fuel feed inlet, and 11 is air-introduced machine.
When the utility model with the fire coal was the raw material operation, raw material entered in the coal-burning boiler system 1 from coal-fired charging aperture 9 and burns, and flue gas passes through the processing of economizer 7, deduster 8 in proper order, enters atmosphere by air-introduced machine 11.When the utility model is raw material with the biomass fuel, biomass fuel enters from biomass feed inlet 10 and carries out non-abundant burning in the biomass gasifying furnace 2, carbon monoxide and not clean-burning biomass material flying dust that burning produces enter separator 3 together, because the centrifugal action of separator 3, not clean-burning biomass material flying dust is because than great and enter separating material material-returning device 4 from the bottom bell mouth of separator 3 and turn back to the burning again that circulates in the biomass gasifying furnace 2, carbon monoxide is then discharged from the top of separator 3, enter the burner hearth of coal-burning boiler system 1 along biomass combustible gas passage 5, fully burn by biomass gas fuel device 6, fully the flue gas of burning back generation enters economizer 7 through coal-burning boiler system 1 circulation, deduster 8 is handled, and enters atmosphere by air-introduced machine 11 at last.
Claims (2)
1, a kind of coal-burning boiler of improvement, it comprises coal-burning boiler system, it is characterized in that: it also comprises the biomass fuel gasifying combustion system that a cover is connected with coal-burning boiler system, described biomass fuel gasifying combustion system comprises biomass gas burner, living beings combustible gas transfer passage, the biomass fuel gasifying system that is linked in sequence, and described biomass gas burner is installed on the burner hearth of described coal-burning boiler system.
2, the coal-burning boiler of a kind of improvement as claimed in claim 1, it is characterized in that: the biomass fuel gasifying system comprises biomass gasifying furnace, separator, the separation material-returning device that is linked in sequence, and the exhaust outlet of described separator is connected with described biomass combustible gas transfer passage.
