    燃气热水锅炉的采用高热阻材料的绝热层具有良好的密封性能和保温效果,有效降低散热损失,采用分体式燃烧机,调节燃烧较好地适应D型布置燃烧空间。
    Gas hot water boiler with heat resistance insulation material has good sealing performance and thermal insulation effect, reduce heat loss, using split type burner, combustion better adapted to D type layout of the combustion space.
    燃气热水锅炉的水处理没有达GB1576-2001标准要求,导致管内严重结垢,造成过热破裂,管子因磨损、腐蚀、壁厚减薄,承压能力随之降低而爆裂,如沸腾段炉管常因烟灰冲刷磨损减薄而破裂,由于安装、设计、运行不当,水循环遭破坏,导致管子过热破坏。
    Water treatment of gas boiler is not up to standard of GB1576-2001, causing the tube serious scaling, causing overheating tube rupture, due to wear, corrosion, wall thickness, the bearing capacity decreased and burst, such as boiling is often broken by soot erosion thinning and section of furnace tube, due to the design, installation, improper operation the water cycle, destruction, lead to tube overheating damage.
    气热水锅炉导热系数反映了材料传导热量的能力,在温差确定的条件下,导热热流与导热热阻成反比,热阻越大,导热热流越小,因而,减少热阻可以增加传热量,因此,不同材料其导热能力不同,相同材料在不同条件下,导热能力也可能有所不同。
    Gas hot water boiler heat conduction coefficient reflects the ability of heat conduction material, the temperature difference is determined, heat flux and thermal resistance is inversely proportional, rezu greater, heat flux is small, therefore, reduce the thermal resistance can increase the heat transfer, therefore, different material its thermal conductivity is not the same, the same material under different conditions, thermal conductivity ability may also vary.
