    作为消耗一次能源的工业锅炉和生活锅炉,因其在生产和生活中的大量使用,对环境的影响(烟尘和粉尘)是最普遍和最直接的,而使用高效、清洁的九卅娱乐可有效的解决这一问题。九卅娱乐自动化程度高、热效率高,可以根据负荷的大小自动调整锅炉的燃烧状况,对我热力厂冬季大负荷运行和夏季小负荷运行的自动调整效率较高。数控采暖锅炉http://www.jnlzsb.com/
    As a primary energy consumption of industrial boiler and life, because of its extensive use in the production and life, the environmental impact of smoke and dust () is the most common and most direct, the use of high efficient and clean gas boiler can effectively solve the problem. Gas boiler high degree of automation, high thermal efficiency, can automatically adjust according to the size of the load condition of boiler combustion, heat to me factory run big load in winter and summer small load operation of the automatic adjustment efficiency is higher.
    燃煤锅炉的炉膛和九卅娱乐比,一般都比较大,有足够的燃烧空间,改造后可增加燃气量,不影响燃烧工况。如果用户要求明显提高锅炉出力,可以适当增加炉膛辐射受热面,同时清除原受热面内外侧的水垢和烟垢,这样在不增大锅炉体积的情况下提高锅炉出力是不成问题的。但必须在做好锅炉的热力计算、烟风阻力计算的同时还要做好强度计算。
    Than coal-fired boiler furnace and gas boiler, is compared commonly big, have enough combustion space, after reconstruction can increase the amount of gas, do not affect combustion conditions. Obviously increase the boiler output if the user requirements, can be appropriately increased the chamber radiation heating surface, the original heating surface at the same time remove the outside of the scale and soot, so without increasing the boiler volume increase the boiler output is not a problem. But must be made in the boiler thermodynamic calculation, smoke wind resistance calculation and strength calculation.
    必须严格制定和执行安全操作规程,特别是在每次点火启动时,一定要做到彻底吹扫工作,掌握好吹扫时间。吹扫时间必须是根据通风机的流量,计算出通风量为三倍炉膛、烟道容积所需要的时间再延时30秒以上。也就是说,必须保证在风门打开后,吹扫的风量容积大于或等于三倍炉膛和烟道的容积量,所需的时间再延持30秒以上。在锅炉运行中注意风—气比例调节,防止出现脱火、回火现象,保证气体完全燃烧。数控采暖锅炉http://www.jnlzsb.com/
    Must develop and implement safety operating rules strictly, especially in every time the ignition starts, must accomplish complete purging work, mastering purging time. Purging time must be according to the flow rate of fan, calculate the ventilation rate for three times the chamber of a stove or furnace, flue volume needed for the time delay of more than 30 seconds. That is to say, must ensure that after the throttle opening, purging the air volume is greater than or equal to three times the amount of volume chamber of a stove or furnace and flue, the time required to postpone holding more than 30 seconds. Pay attention to the wind in the boiler operation - gas ratio control, prevent fire, tempering phenomenon, ensure complete combustion gases.
