The boiler can effectively shorten the height of a circulating bed boiler and burn fuels such as inferior coals and biologic materials, so that the boiler is a highly efficient hot water boiler with the advantages of clean combustion and compact structure.
Description
Technical field
The utility model relates to the horizontal CFBB of a kind of level, belongs to the Industrial Boiler for the production or the purposes such as the heat supply of hot water, heating are provided of living.
Background technology
China mainly is chain furnace at the coal-burned industrial boiler of usefulness at present, also has part fluidized bed furnace and CFBB simultaneously, and the different type of furnaces has different separately requirements to garbage fuel, and pluses and minuses are separately also arranged.
Recirculating fluidized bed is the combustion technology of high-efficiency cleaning, and fuel tolerance is wide, fuel such as burning differing texture coal (comprising gangue and sulphur coal, brown coal), solid waste.Burning in circulating fluid bed boiler efficient height is a low NOx combustion equipment, can also realize desulfuration in furnace simultaneously, has low NO
xAnd SO
xAdvantages such as discharging.Domestic CFBB in usefulness all is vertical structure at present, there are the shaft height in this traditional vertical, a CFBB, shortcomings such as boiler island is bulky, the supporting steel frame of boiler and the steel of boiler body consumption are bigger, also make Project Cost and initial cost increase.Traditional vertical, a CFBB rely on the fluidization circulation of bed material and fuel to reach abundant mixed combustion, must guarantee certain solid circulating rate, therefore are difficult to realize miniaturization.Chain furnace is had relatively high expectations to institute's combustion fuel, generally requires the combustion fuel quality preferable and stable, and relatively more responsive to fuel reaction, fuel tolerance is not strong.So domestic coal-burned industrial boiler, especially coal-fired chain furnace inefficiency, seriously polluted, both caused energy waste, polluted environment again.
At domestic industry boiler present situation, the development miniaturization, the requirement that has simultaneously the coal-burning boiler of advantages such as the high and low disposal of pollutants of efficiency of combustion, fuel tolerance be wide again concurrently more shows urgent.The utility model adapts to the recirculating fluidized bed hot-water boiler that this needs provide a kind of horizontal layout just.
The utility model content
The utility model is at the high pollution of present Industrial Boiler poor efficiency, and the relatively more expensive present situation of CFBC equipment enlarging, cost, a kind of horizontal recirculating fluidized bed hot-water boiler is provided, make its miniaturization, have all advantages of CFBB simultaneously concurrently, can be widely used in the burning of various fuel, have higher efficiency of combustion and lower disposal of pollutants performance.
The technical solution of the utility model is as follows:
A kind of horizontal recirculating fluidized bed hot-water boiler is characterized in that: this boiler is made up of charging gear, air compartment, main chamber, two passage combustion chambers, primary separator, triple channel combustion chamber, second-stage separator, economizer etc.; Described main chamber, two passage combustion chambers and triple channel combustion chamber are separated by water-cooling wall, and main chamber and top, two passage combustion chambers are provided with flue gas and material channel, and two, bottom, triple channel combustion chamber is provided with flue gas and material channel; Described primary separator is arranged on two, bottom, triple channel combustion chamber, form by the water-cooling wall bending of bottom, combustion chamber, and be one-level U type separator, undertaken by the separative efficiency low principle of trying one's best during design.
In technique scheme, combustion chamber, second-stage separator and economizer are as stand-alone assembly; The combustion chamber links to each other with second-stage separator by triple channel combustor exit exhaust gases passes, and second-stage separator links to each other with economizer by separator fairlead flue.Second-stage separator adopts the structural shape of cyclone separator, can realize the efficient separation of material.
The utility model compared with prior art has the following advantages and the high-lighting effect: the utility model adopts the horizontal layout of level, and compact conformation can reduce the height of boiler greatly, saves the boiler steel consumption, effectively reduces the boiler cost; The utility model has all advantages of recirculating fluidized bed concurrently, is the high-efficiency cleaning combustion apparatus of a kind of many fuel, wide adaptability, and efficiency of combustion height (can reach more than 85%), and the energy desulfuration in furnace has low NO
xAnd SO
xAdvantages such as discharging.
Description of drawings
Fig. 1 is the related horizontal recirculating fluidized bed hot-water boiler schematic diagram of the utility model.
Among the figure: the 1-charging gear; Air compartment of 2-; The 3-main chamber; 4-two passage combustion chambers; The 5-primary separator; 6-triple channel combustion chamber; The 7-fin panel casing; The 8-second-stage separator; The 9-economizer; 10,11-flue gas and material channel.
The specific embodiment
Describe concrete structure of the present utility model, operation principle and embodiment in detail below in conjunction with accompanying drawing:
The utility model provides the recirculating fluidized bed hot-water boiler of the horizontal layout of a kind of level, comprises charging gear 1, air compartment 2, main chamber 3, two passage combustion chambers 4, primary separator 5, triple channel combustion chamber 6, second-stage separator 8, economizer 9 etc.Described main chamber 3, two passage combustion chambers 4 and triple channel combustion chamber 6 are separated by fin panel casing 7.Fuel (coal of various qualities, or special fuel such as living beings) is sent in the main chamber 3 by charging gear 1 and is expected fully to mix and burn with bed.Mixture rises along burner hearth, enters two passage combustion chambers 4 from the flue gas on main chamber 3 tops and material channel 10 and burns away.Partial material is separated by primary separator 5 by inertial separation and is returned in the main chamber 3, and most of material enters triple channel combustion chamber 6 abundant after-flames by the flue gas and the material channel 11 of bottom, two passage combustion chambers.Described primary separator 5 is arranged on two, bottom, triple channel combustion chamber, is formed by the water-cooling wall bending of bottom, combustion chamber.The material and the flue gas that come out from triple channel combustion chamber 6 enter second-stage separator 8 and efficiently separate, and the loopback of material that separates is to main chamber 3, and the flue gas after the separation carries out heat exchange through economizer 9 and produces hot water for producing or the life use.Material has formed the two-stage Zigzag type and has flowed between main chamber and two, triple channel combustion chamber, changed the vertical ciculation fluidized bed structure of traditional one-level, has formed the circulation of two stage materials, makes the adjusting function of boiler operatiopn better, and efficiency of combustion is higher.
Described combustion chamber, second-stage separator 8 and economizer 9 are as stand-alone assembly.The combustion chamber links to each other with second-stage separator 8 by triple channel combustion chamber 6 outlet exhaust gases passes, and second-stage separator 8 links to each other with economizer 9 by separator fairlead flue.Main chamber and two, triple channel combustion chamber and second-stage separator adopt and are arranged in juxtaposition form, and boiler height can greatly reduce.
