Abstract
The invention relates to a hybrid energy boiler capable of simultaneously and respectively putting solid fuels (coal and organic matters), liquid fuels (oil and methanol) and gaseous fuels (natural gas and dimethyl ether) into operations and electrically heating. The boiler can be used for simultaneously putting various fuels into operations, and one of the fuels can be singly burnt to support the normal work of the boiler. The boiler does not singly rely on a certain fuel, and the putting proportion of various fuels can be adjusted so as to ensure that the cost of the fuels is the minimum, which is beneficial to the economic operation of the boiler.
Description
(1) technical field
The present invention relates to a kind of energy and throw combustion solid fuel (coal, organic matter), liquid fuel (oily, methyl alcohol), gaseous fuel (natural gas, dimethyl ether) and electrically heated boiler simultaneously and respectively.
(2) background technology
Along with rapid economy development, the consumption of the energy is more and more, and is also increasing to the influence of environment; the cry day of environment and ecological protection is stronger; and in recent years, because rising steadily of oil and coal price causes the production and operation cost of boiler significantly to rise.
Existing boiler is thrown fuel and is mainly adopted three kinds of modes, and the one, only throw combustion single-fuel (coal-burning boiler, oil burning boiler, gas fired-boiler); The 2nd, based on a kind of fuel, another kind of fuel ignition combustion-supporting (garbage fired boiler, heavy oil, coal water slurry boiler); The 3rd, adopt two kinds of fuel of oil gas, ordinary production can only be used a kind of fuel.Above-mentioned boiler is too strong to the dependence of single-fuel, when obstacle appears in leading fuel stream supply, just must stop production.And, when energy prices change, can't adjust the proportioning of fuel band and various fuel, also just can't realize most economical fuel ratio throwing combustion.
(3) summary of the invention
The present invention develops a kind of hybrid energy boiler, realizes the optimality price ratio that fuel is thrown in.This hybrid energy boiler can be thrown the combustion pluralities of fuel simultaneously, also can be with the support normal operation of boiler of burning separately of any fuel wherein.This boiler does not rely on a certain fuel separately, when the temporary transient shortage of certain fuel, throws burning-out with other fuel and can work on entirely.In addition, when the energy supply price changes on the market, can adjust the ratio of various fuel, make fuel cost be in minimum state, the economical operation of favourable boiler.
The invention has the beneficial effects as follows, can be according to the energy market situation, the rapid adjustment fuel structure, the while does not influence the ordinary production of boiler, reaches the minimum purpose of production of steam cost.
(4) description of drawings
Accompanying drawing is the schematic diagram of primary structure of the present invention.
1. water-coal-slurry burners, 2. oil-gas two-way burner, 3. coal bunker among the figure, 4. electric heater unit (resistance heating tube or electromagnetism heating), 5. fire grate (fixed grate, moving grate, reciprocal grate, vibrating-grate stoker, traveling-grate stoker etc.), 6. grey slag bucket, 7. oxygen-enriched combustion-supporting system.
(5) specific embodiment
The mixing energy supply that realizes hybrid energy boiler is with following several ways:
1, boiler can burn liquids and gases fuel such as water-coal-slurry, oil, gas, methyl alcohol, dimethyl ether input boiler furnace by water-coal-slurry burner (1) and the oil-gas two-way burner (2) that is installed on front wall or side wall, in conjunction with energy supply situation, combustion control system is the ratio of fuel metering automatically, thus the size of control fire box temperature and thermic load.
2, boiler drops into coal or organic matter by coal bunker (3), enters in the stove through fire grate (5) then.After the air that burning needs is sent into fire grate abdomen apoplexy storehouse by blower fan, be upward through fire grate and coal or organic matter and carry out combustion reaction formation high-temperature flue gas, fuel burnouts into lime-ash at last, discharges through grey slag bucket at the fire grate end.
3, boiler is by the medium in electric heater unit (4) heating drum or the superheater.
4, boiler is adjusted fuel delivery system by combustion control system, thereby changes the ratio between the various fuel, and guarantees its burning fully, satisfies the requirement of fire box temperature and thermic load.
5, oxygen-enriched combustion-supporting system (7) can put into operation when mixing for combustion or independent a kind of fuel, makes burning fully, reduces burnup.
Claims (5)
1. hybrid energy boiler, comprise boiler body and boiler auxiliaries, it is characterized in that: can be simultaneously and put into operation separately solid fuel, liquid fuel, gaseous fuel or electrical heating, water-coal-slurry burner, oil-gas two-way burner, electric heater unit and corresponding air feed and smoke evacuation system are installed on the body of heater.
2. hybrid energy boiler according to claim 1 is characterized in that water-coal-slurry burner or oil-gas two-way burner are installed on boiler front wall or side wall, can parallel installation or installation up and down between two kinds of burners.
3. hybrid energy boiler according to claim 1 is characterized in that electric heater unit can be arranged in the outer or drum of drum.
4. hybrid energy boiler according to claim 1 is characterized in that fire grate can carry coal or organic matter.
5. hybrid energy boiler according to claim 1 is characterized in that the oxygen-enriched combustion-supporting system can realize part or whole oxygen-enriched combusting.
