Abstract
The utility model discloses an organic heat transfer material heater of a fluidized bed, which comprises a crush feeding device (1), a hearth (3), a reburning chamber (5) and a convection heating surface (6), wherein, a fluidized combustor (2) that is communicated with a pressure equalizing air box (4) is arranged at the bottom part of the hearth (3). The heater has high burning efficiency and fuel used has strong adaptability, resulting in effectively reducing generation of sulfide and nitride and dust on the heating surface, thereby being characterized by environmental protection, energy saving and high efficient.
Description
Technical field
The utility model relates to a kind of energy-saving and environmental protection type heating equipment in industry extensive application prospects such as grease, application, printing and dyeing, building materials, timber, food, chemical industry, particularly relates to a kind of organic heat carrier furnace.
Background technology
The coal burning organic heating medium furnace burner is generally the traveling-grate stoker mode at present, and there is following shortcoming in it in actual applications: 1, ature of coal is had relatively high expectations, be generally II, III class bituminous coal.2, owing to environmental issue and fire grate steel construction intensity reason, chain grate boiler design rated power is general≤and 40 tons/hour, if increase tonnage again, then the burner structure is too complicated, steel consumption also will increase greatly; 3, there is high temperature lower seal difficulty in the traveling-grate stoker structure, and the system of bf body problem such as serious of leaking out makes boiler exhaust gas heat loss, gas heat loss due to incomplete combustion and heat loss of imperfect solid combustion be difficult to effective reduction, is restricting the raising of boiler thermal output; 4, owing to reasons such as fire grate structure space make the arrangement of boiler heating surface be easy to generate dust stratification, boiler thermal output is reduced, wasted the energy.
Summary of the invention
For solving the existing type of furnace at parameter maximization, fuel tolerance, ature of coal burnout rate and effectively improve boiler thermal output, effectively reduce the deficiency of aspect existence such as the discharging of Sization thing and Nization thing and fouling of heating surface, the utility model provides a kind of have environmental protection, energy-conservation, fluid bed organic heat carrier furnace efficiently.
Technical solution adopted in the utility model is: this organic heat carrier furnace comprises pulverizing feed arrangement 1, burner hearth 3, burning chamber 5 and the convection heating surface 6 that links to each other successively, and the bottom of burner hearth 3 is provided with the fluidized bed combustion device 2 that air compartment 4 is all pressed in connection.
Advantage of the present utility model is: 1, environmental-protecting performance is superior: the employing of fluidized bed combustion mode can effectively suppress the Sization thing and the Nization thing generates, the environmental requirement that makes fume emission be up to state standards and stipulate.2, economy price ratio height, energy-saving effect is remarkable: the broadness that coal adapts to effectively reduces the cost of boiler operatiopn.3, the product operation is efficient: the optimal design of heating surface makes boiler overall thermal efficient be improved.4, Operation and Maintenance is strong: the employing of automatic monitoring control equipment makes boiler plant heat supply control accurately, and is reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
, pulverizing feed arrangement 1, burner hearth 3, burning chamber 5 and convection heating surface 6 link to each other successively as shown in Figure 1, and fluidized bed combustion device 2 is positioned at the bottom of burner hearth 3, all press the air port of air compartment 4 to be located at the bottom of fluidized bed combustion device 2.
Granularity is that the ature of coal of 8-10mm is sent in the fluidized bed combustion device 2 of burner hearth 3 bottoms by pulverizing feed arrangement 1, is stable gas-solid fluidized state under the high-speed air flow effect about 35m/s in bed, carries out violent fluidized bed combustion.Flow through burner hearth 3, burning chamber 5 of high-temperature flue gas after the burning enters convection heating surface 6.The burning required air distributes by all pressing air compartment 4, the 2 tissue burnings of fluidized bed combustion device, and the flue gas that produces in 3 burnings of primary zone burner hearth further burns and ash disposal in burning chamber 5, to prevent flue gas wearing and tearing convection heating surface 6.In convection heating surface 6, finish the heat exchange of high-temperature flue gas and conduction oil, the output high temperature heat conductive oil.
Because gas-solid phaseization makes fuel and air contacted specific surface area increase greatly, and efficiency of combustion can be reached more than 94%.Fuel tolerance is strong, and various high ash contents such as burning lambskin, bone coal, brown coal, spoil are difficult coal-fired.When using sulphur coal, in ebullated bed, add the generation that a certain amount of lime stone can effectively suppress the Sization thing.Low temperature combustion mode can effectively reduce the generation of Nization thing.The arrangement of heating surface effectively reduces the overall dimensions of product and the possibility of dust stratification.
