Abstract
The utility model discloses a low pressure and high temperature steam generating and water heating boiler. The case body and the flue of the boiler form a casing interlayer, which is fixed and connected by convection heating tubes at the top and bottom. The convection heating tubes are arranged respectively on a suspended inner bag and the casing interlayer and in the flue, and a circular superheater is fixed above the flue. The boiler has circular and square fire grates pieced together with the square ones in the middle. The airing ring of the circular air preheater, which is connected to an inlet air duct at the bottom, is arranged under the fire grates. Four preheating air pipes, which are distributed uniformly on the airing ring and communicated vertically with the airing ring, extend through the casing interlayer into a combustion chamber with the jet nozzles forming a 90-DEG angel between each other.
Description
The utility model relates to a kind of low-voltage high-temperature dual purpose steam water boiler.
Traditional thermal technology's theory is " steam pressure is directly proportional with vapor (steam) temperature ", the user need use the high-temperature steam greater than 120 ℃, just need to improve boiler pressure, purchase high-pressure boiler, not only cost an arm and a leg, and use maintenance cost very high, safety coefficient is little, and the dual purpose steam water boiler volume that occurs on the current market is big, unreasonable structure, combustion system falls behind, the consumption coal is many, over-emitting black exhaust, ascension speed is slow, steam production is little, efficient is low, and can not produce and use the high-temperature steam greater than 120 ℃.
The utility model is at above-mentioned deficiency, but provide that a kind of volume is little, heat transfer area big, smokeless operation, energy-conserving and environment-protective all are better than existing like product, just the output high-temperature steam, the novel low-voltage high-temperature dual purpose steam water boiler of low pressure operation.
Task of the present utility model is finished as follows: the shell body of boiler and flue constitute the overcoat interlayer, inner hanging chamber is arranged on the top, combustion chamber, and by last Convective Heating pipe, fixedly UNICOM is together for following Convective Heating pipe and overcoat interlayer, on the face of cylinder of inner hanging chamber, be evenly distributed with and hang courage Convective Heating pipe, overlap equally outside in the inboard flue of interlayer and also be evenly distributed with overcoat Convective Heating pipe, the upper fixed of flue has ring-like superheater, boiler grate is circle, side's assembled piece type, wherein circular piece fire grate and body of heater are fixed together, the centre is square moving grate, is provided with the solar or lunar halo of ring-like air preheater below the fire grate; Be connected with the air intake tube that connects air blast below the solar or lunar halo of described ring-like air preheater, above four pre-warm-air pipes evenly distribute, and with the solar or lunar halo vertical connection, pass the overcoat interlayer again, the nozzle end is mutually an angle of 90 degrees and stretches into the combustion chamber.During operation, a large amount of heats that the combustion chamber produces rush at the top inner hanging chamber, and inner hanging chamber is heated by self and hangs courage Convective Heating pipe and carry out the body partial circulating; The overcoat interlayer also by self be heated and overcoat Convective Heating pipe carry out the body partial circulating; Inner hanging chamber carries out comprehensive big convection current, systemic circulation, carries out heat exchange with the stove water in the global interlayers by Convective Heating pipe up and down.
The utility model is owing to adopt ring-like air preheater, can make air through preheating from being mutually the nozzle end of an angle of 90 degrees, ejection fast, and vapour is sent in rotation, forces to add oxygen and aiding combustion to flame kernel, impels fuel gas fully to mix, and chemical combination combustion reaches a high temperature; Again owing to adopt many Convective Heating pipes, strengthened heat transfer area, make heat exchange abundant, improved boiler evaporating speed as quick as thought, boiler duty and operating efficiency have further been improved, a large amount of saturated vapors through repeatedly circulation, Fast Heating produce rise in the steam receiver of upper boiler space; Simultaneously, adopt ring-like superheater, back and forth heating continuously, moisture in 120 ℃ the saturated vapor can be evaporated by rapid cracking, and become (180-300 ℃) superheated steam that contains high heat energy, and, to serving, thereby all finish the working procedure of low-voltage high-temperature with heat unit from superheater tube ejection.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Fig. 1 is the utility model overall structure front section view.
Fig. 2 is the utility model overall structure side sectional view.
Fig. 3 is the boiler grate structure chart.
Fig. 4 is that ring-like air preheater of boiler and body of heater are installed diagrammatic sketch.
Fig. 5 is the pre-warm-air pipe nozzle of the ring-like air preheater of boiler angle diagrammatic sketch in the combustion chamber.
With reference to accompanying drawing 1.2.3.4, shell body [1] constitutes overcoat interlayer [5] with flue [2], inner hanging chamber [6] is arranged on top, combustion chamber [3], and by last Convective Heating pipe [7], following Convective Heating pipe [8], fixedly UNICOM is together with overcoat interlayer [5], on the face of cylinder of inner hanging chamber [6], be evenly distributed with and hang courage Convective Heating pipe [9], inboard flue [2] lining of overlapping interlayer [5] equally outside also is evenly distributed with overcoat Convective Heating pipe [10], the upper fixed of flue [2] has ring-like superheater [4], boiler grate [11], [12] be circle, side's assembled piece type, wherein circular piece fire grate [11] is fixed together with body of heater [1], the centre is square moving grate [12], is provided with the solar or lunar halo [14] of ring-like air preheater [13] below the fire grate; With reference to accompanying drawing 5, be connected with the air intake tube [15] that connects air blast below the solar or lunar halo [14] of described ring-like air preheater [13], above four pre-warm-air pipes [16] evenly distribute and with solar or lunar halo [14] vertical connection, pass overcoat interlayer [5] again, nozzle end [17] is mutually an angle of 90 degrees and stretches into combustion chamber [3].
