Abstract
The utility model discloses a heat-conduction oil boiler of a recirculating fluidized bed, which comprises a radiation heated device (1) and a convection heat transfer part (2) and is characterized in that the lower part of the radiation heated device (1) is provided with a combustion chamber (3); the combustion chamber (3) is provided with an ash outlet (4), a wind feed tube (5) and a coal feeding device (6); the upper part of the radiation heated device (1) is provided with a radiation heat transfer part (7) which is in a vertical film type wall tube structure; a cyclone separator (8) is arranged between the radiation heated device (1) and the convection heat transfer part (2); the convection heat transfer part (2) comprises a plurality of sets of convection banks; and an air preheating part (9) is arranged below the convection heat transfer part (2). In the utility model, heat-conduction oil in the film type wall tube of the radiation heat transfer part exchanges heat with high-temperature fume, then the fume rises upward and turns to enter a convection chamber after passing through the cyclone separator, and coal ash generated through rotational separation in the cyclone separator downward flows back to the combustion chamber for further combustion so that one circulating process is completed; the plurality of sets of the convection banks of the convection heat transfer part carries out heat convection to the fume, and then the air preheating device recovers waste heat so as to improve the heat efficiency of the boiler. The heat-conduction oil boiler in the utility model has the advantages of high combustion efficiency and obvious energy-saving effect.
Description
Affiliated technical field
The utility model belongs to a kind of heat-transfer device, is a kind of heat-conducting oil furnace particularly.
Background technology
In the prior art, the coal burning heat-conducting oil stove burner hearth of domestic current generally adopts the traveling-grate stoker of grate firing, and top as the radiation heating section, directly enters the convection section of being made up of many rows coiled pipe of back with spiral coil after high-temperature flue gas and the coil pipe heat exchange.The deficiency of its existence is: the high-temperature flue gas flow process is short, and utilization rate is low, and the operating cost height wastes energy.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of recirculating fluidized bed heat-conducting oil furnace is provided, its efficiency of combustion height, and operating cost is low, and energy-saving effect is obvious.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: radiation heating device, convection heat transfer' heat-transfer by convection parts, it is characterized in that: the bottom of radiation heating device is the combustion chamber, the combustion chamber is provided with ash hole, gives airduct, feeding system, top is the radiant heat transfer parts, and the radiant heat transfer parts are vertical membrane wall tubular construction; Be provided with cyclone separator between radiation heating device, convection heat transfer' heat-transfer by convection parts, cyclone separator is a funnel-form, and the upper end is communicated with the convection heat transfer' heat-transfer by convection parts, and the lower end is communicated with the combustion chamber; The convection heat transfer' heat-transfer by convection parts are the convection bank of many groups, are provided with the air preheat parts below the convection heat transfer' heat-transfer by convection parts.
The utility model is taked technique scheme, have following beneficial effect: vertical membrane wall circumference of cannon bone of the present utility model becomes the radiant heat transfer space, the high-temperature flue gas that the combustion chamber produces is flow at high speed from bottom to top, conduction oil in the membrane wall pipe from bottom to top moving greater than the speed of 2 meter per seconds, and is finished heat exchange with high-temperature flue gas along tube wall.Upwards turn and enter the right side convection cell through cyclone separator in middle part, high-temperature flue gas, the coal ash that rotation is separated in separator flows downward, and gets back to the combustion chamber and further burns, and finishes a cyclic process.Many groups convection bank of convection heat transfer' heat-transfer by convection parts and smoke convection heat exchange, bottom are air preheater, recovery waste heat, and the thermal efficiency of raising boiler, the hot-air after being heated is delivered in the combustion chamber in left side, is beneficial to burning.The utility model coal combustion circulates, and the efficiency of combustion height can burning low grade coal, reduce the cost of boiler operatiopn, and energy-saving effect is remarkable.The radiation heating device adopts unique membrane wall tubular construction, vertically arranges along the direction of flow of flue gas, reduces the friction of pipe and flue gas, thereby reduces the wearing and tearing of pipe, the service life of prolonged boiler.The utility model air preheater and boiler design are integral, and can improve the thermal efficiency of boiler.
