QXL 新型大容量复合循环水管式热水日本极品a级片性能特点:
(1)前、后墙水冷壁及前、后拱管均采用回水强制引射装置,保证了这些循环回路在运行时各受热管的水速远高于其安全水速,保证了停电时水循环的安全性;
(2)侧水冷壁管和对流管束采用强制循环,保证了此系列管束中的水速远高于安全水速,并能冲走下部简体的沉积物,彻底消除了水冷壁管爆管的可能。如果在运行中发生停电事故,侧水冷壁管与对流管束会自动构成自然循环回路,充分保证了侧水冷壁管和对流管束的运行安全:
(3)炉膛被包覆在对流受热面内侧,由于两侧及前部对流受热面烟道内的烟气温度低,保温效果显著,蒙皮散热损失小;
(4)前后炉拱采用导流设计,后拱低而长,覆盖率高:燃烧灼热高温烟气能在后拱的作用下,掠过燃烧着的煤层冲向前拱,在前拱的导流作用下,对进入炉膛的新煤层进行强烈加热,并使部分燃烧的碳粒辐射在煤层上, 使煤迅速着火和稳定燃烧,所以,本炉型对煤种适应性较好,燃烧完全,日本极品a级片热效率高;
(5)日本极品a级片本体成框架结构,采用侧水冷壁与水管对流管束并联组合结构作为整个日本极品a级片的支撑部件。在工作状态下,日本极品a级片受热面可以自由向上热膨胀,消除了热应力,结构稳定可靠;
(6)日本极品a级片对流受热面全部采用烟气横向冲刷方式,不仅受热面传热效率高,出力大,升温快,而且可以在各对流受热面烟道合理地设计布置清灰门和检修门,非常便于运行管理和检修,这对于运行负荷变动幅度较大的大容量热水日本极品a级片是重要的;
(7)由于采用水管式受热面和下支撑式本体结构,相对同容量的其它炉型日本极品a级片,新型大容量复合循环水管式热水日本极品a级片的高度比同容量的其它炉型日本极品a级片降低约 15% -35%,并且容量越大,其高度降低的幅度越大,这会大大降低日本极品a级片房的造价,为用户节约基本建设投资:
注:尽可能采用高温水运行,杜绝出水温度长期 70℃的运行。
  
Performance characteristics:QXL new large-capacity combined cycle pipe type hot water boiler
(1)the front and back wall before and after water wall and arch pipe adopt mandatory backwater ejector device, ensure that the loop at run time of each tube water speed is much higher than the lowest safe water speed, make sure the safety of the water cycle to case of power failure;
(2)the side water wall tube and convection bank adopts the forced circulation, ensures that the series, the water        in a speed far higher than the safe water speed, and can wash away the bottom sediments of simplified, eliminated the possibility of water wall tube tube. If blackout accidents occurred in the running, side water wall tube and convection bank will automatically constitute a natural circulation loop, fully guaranteed the side water wall tube and the safety operation of the convection bank:
(3)furnace was enshrouded in the inside of the convection heating surface, due to the sides and the front of the convection heating surface of flue gas temperature is low, heat preservation effect is remarkable, skin heat loss small;
(4)the furnace arch before and after using the diversion design, low arch after long, high coverage: combustion heat to the back arch under the action of high temperature flue gas, through the burning coal seam rushed forward, in the front arch under the action of the diversion, to enter the new coal seam of strong heating furnace, and makes the partial combustion of carbon particle radiation on coal seam, making quick ignition and stable combustion of coal, therefore, this type furnace for coal has good adaptability, complete combustion, boiler thermal efficiency is high;
(5)boiler body into a frame structure, the lateral wall and water pipes convection bank parallel combination structure  as the support of the whole boiler components. In working status, boiler heating surface free thermal expansion upward, to eliminate the thermal stress, the structure is stable and reliable;
(6)boiler convection heating surface all adopts horizontal flue gas flushing method, not only high heat transfer efficiency of heating surface, the output is big, warming faster, but also in the convection heating surface flue design layout reasonably clear grey doors and access door, very convenient for operation and management and maintenance, for the larger operation load variations of large capacity hot water boiler is extremely important;
(7)due to the use of heating surface of pipe and the support structure of ontology, comparing with the capacity of other type boiler furnace, a new type of large-capacity combined cycle than the height of the pipe type hot water boiler with the capacity of other type furnace boiler reduce about 15% - 15%, and the greater the capacity, a larger decrease its height, it will greatly reduce the cost of boiler room for the user to save the capital construction investment:
Note: as far as possible, using high temperature water running, put an end to the operation of the water temperature 70 ℃ for a long time.
