Abstract

The invention provides a boiler using old industrial rubber as the fuel, which uses the old rubber which is the waste of chemical production as the main fuels, thus saving a large quantity of non-renewable mineral fuels and saving energies, at the same time, reducing the problem of environment pollution caused by the discard of the old industrial rubber, moreover, effectively solving the coking problem of the old rubber in the burning process and improving the burning efficiency of the boiler. The boiler using industrial old rubber as the fuel comprises a furnace hearth, an chain grate, a coal providing device, a horizontal smoke channel, a tail smoke channel and equipment for slag and dust discharge, wherein the chain grate is arranged in the lower part of the furnace hearth, the coal providing device is arranged in the front of the furnace hearth; the outlet end of the furnace hearth is the horizontal smoke channel. The boiler is characterized by also comprising an old industrial rubber feeding device that is arranged in front of the furnace hearth and on the back part of the coal providing device.

Description

Industrial overage compound fuel boiler
(1) technical field
The present invention relates to the non-fossil fuel steam generator system, be specially a kind of industrial overage compound fuel boiler.
(2) background technology
In providing thermo-power station, industrial production for oneself, need to use the steam of boiler generation, the normally used fuel of boiler is fossil fuel, as coal, oil and gas etc.Fossil fuel are non-renewable primary energy, owing to be becoming tight primary energy supply day, price is constantly soaring, cause production cost constantly to increase, industrial overage compound is the discarded object of Chemical Manufacture, if abandon as industrial refuse, not only wasting resource also pollutes the environment, utilize industrial overage compound in boiler, to burn, the steam that produces is used for generating or steam supply, has energy savings, reduce the social benefit of environmental pollution, good economic benefits is also arranged, but because the industrial overage compound fusing point is low, the characteristic of easy bonding, if it is acted as a fuel when being directly used in common coal-burning boiler, can produce serious coking phenomenon on grate surface, and make fuel combustion insufficient, combustible loss is big.
(3) summary of the invention
At the problems referred to above, the invention provides industrial overage compound fuel boiler, its discarded object industrial overage compound with Chemical Manufacture is a main fuel, a large amount of non-renewable mineral matter fuel have been saved, energy savings, also reduced because of industrial overage compound abandons the problem of environmental pollution that causes simultaneously, and can effectively solve the coking problem of industrial overage compound in combustion process, improved the efficiency of combustion of boiler.
Its technical scheme is such: it comprises burner hearth, traveling-grate stoker, coal feeder, horizontal flue, back-end ductwork and slags tap and ash discharge equipment that described traveling-grate stoker is arranged in the bottom of described burner hearth, and described coal feeder is installed in described furnace front; The port of export of described burner hearth is described horizontal flue, it is characterized in that: it also comprises the industrial overage compound charging gear, and described industrial overage compound charging gear is installed in the preceding described coal feeder rear portion of described burner hearth.
It is further characterized in that: be furnished with face arch and rear arch above described lower furnace portion, described traveling-grate stoker, and arrange the secondary steam wind system at described face arch and arch place, back; In described horizontal flue, be furnished with high temperature superheater and low temperature superheater; Described slag tap and ash discharge equipment be installed in described chain fire-gate below; Arrange economizer and cast-iron air preheater in the described back-end ductwork; Described furnace outlet is furnished with the crust block pipe.
Use industrial overage compound boiler of the present invention, its beneficial effect is: saved a large amount of non-renewable mineral thing fuel, reduced because of industrial overage compound abandons the problem of environmental pollution that causes, and can effectively solve the coking problem of industrial overage compound in combustion process, improved the efficiency of combustion of boiler.
(4) description of drawings
Fig. 1 is an industrial overage compound boiler structure schematic diagram of the present invention.
(5) specific embodiment
See Fig. 1, the present invention includes burner hearth 1, traveling-grate stoker 8, coal feeder 7, horizontal flue 13, traveling-grate stoker 8 is arranged in the bottom of burner hearth 1, and coal feeder 7 is installed in burner hearth 1 front portion; The port of export of burner hearth 1 is a horizontal flue 13, and it also comprises industrial overage compound charging gear 6, and industrial overage compound charging gear 6 is installed in burner hearth 1 preceding coal feeder 7 rear portions; Face arch 14 and rear arch 15 have been arranged in the top of burner hearth 1 bottom, traveling-grate stoker 8, and arrange secondary steam wind system 10 at face arch 14 and rear arch 15 shapes place; In horizontal flue 13, be furnished with high temperature superheater 3 and low temperature superheater 4; Be furnished with soot blower on each heating surface.Installation is slagged tap and ash discharge equipment 9 below traveling-grate stoker 8, is furnished with crust block pipe 11 in the outlet of burner hearth 1, also connects back-end ductwork 12 behind horizontal flue 13, arranges economizer 2 and cast-iron air preheaters 5 in the back-end ductwork 12.
During boiler operatiopn, at first coal feeder 7 is distributed in coal on the traveling-grate stoker 8, industrial overage compound charging gear 6 upper strata that industrial overage compound is evenly distributed on coal enters jointly in the burner hearth 1 and burns then, because the coal seam isolates industrial overage compound and fire grate, not only can reach the purpose of the old glue of burning industrial, and prevented industrial overage compound coking on grate surface effectively, simultaneously, by the face arch 14 above fire grate 8, arranged and rear arch 15 and at face arch 14, rear arch 15 places arrange secondary steam wind 10, adopt steam to spray and cause generation whirlpool in the burner hearth, fuel gas is mixed with excess oxygen, it is inhomogeneous to change the interior gas of burner hearth, reach burning fully, reduce imperfect combustion loss, fully the flue gas of burning back generation enters back-end ductwork 12 by high temperature superheater 3 and low temperature superheater 4 in the horizontal flue 13 respectively in proper order, high temperature superheater 3 and low temperature superheater 4 in the horizontal flue 13 can be arranged by actual instructions for use, when the parameter of steam is medium temperature and medium pressure, then need to arrange high temperature superheater 3 and low temperature superheater 4, when the parameter of steam is low-temp low-pressure, then need to arrange low temperature superheater 4, saturated stove does not then need to arrange superheater.All arrange soot blower at each heating surface place, can in time remove coking and dust stratification on the heating surface, do not influence the heat transfer of each heating surface.
