    影响常压锅炉日常安全运转的要素有哪些
    What are the factors that affect the daily safe operation of atmospheric boilers?
    燃气锅炉指的是燃料为燃气的锅炉,包含燃气开水锅炉、燃气热水锅炉、燃气蒸汽锅炉等。燃气锅炉运用前查看炉筒、炉胆、烟管、封头及拉撑等受压部件能否正常,有无严重腐蚀或变形、裂纹,炉内有无水垢、杂质、有无东西物件等留传在内,一起,承认无人在锅炉时,方可封闭一切人孔、手孔、装入孔、手孔,盖时,应将压盖放正,孔盖之间应垫石棉橡胶圈或用石棉绳编制的石棉绳垫。
    Gas-fired boilers refer to boilers whose fuel is gas, including gas-fired boilers, gas-fired hot water boilers, gas-fired steam boilers, etc. Before using the gas-fired boiler, check whether the pressurized parts such as the hearth, the furnace gall, the flue gas pipe, the head and the stretching brace are normal, whether there are serious corrosion or deformation, cracks, whether there are scales, impurities and objects left in the furnace. Together, it is admitted that all manholes, hand holes, loading holes and hand holes can be closed only when nobody is in the boiler. When covering, the cover should be put in the right position, and the asbestos rubber ring or asbestos rope mat made of asbestos rope should be padded between the hole caps.
    1.常压当承压运用
    1. atmospheric pressure should be used under pressure.
    将常压热水锅炉直接和自来水或采暖系统密闭循环。也就是将锅炉本体上与大气相通的排汽管作为回水管运用,使锅炉本体一直处于满水承压状态。这种密闭循环方法有两种危害:第一是当炉水温度过高时,发生的蒸汽无法分泌出去,因而压力会不断上升,爆破和走漏事端随时都有可能发生。第二是即便炉水温度不高,不会发生很多蒸汽,但由于有循环泵的效果,锅炉本体接受热水循环压力是较高的。
    The atmospheric hot water boiler is directly closed to the tap water or heating system. That is to say, the exhaust pipe connected with the atmosphere on the boiler body is used as a return water pipe, so that the boiler body is always in full water pressure state. There are two kinds of hazards in this closed cycle method. First, when the temperature of the furnace water is too high, the steam can not be secreted, so the pressure will continue to rise. Blasting and leakage can happen at any time. Secondly, even if the temperature of boiler water is not high, there will not be much steam, but because of the effect of circulating pump, the boiler body accepts higher circulating pressure of hot water.
    将常压热水锅炉装置在一楼或地下室,热水贮水箱装置在楼顶,这种方法同样是把锅炉本体上与大气相通的排汽管当作回水管运用。尽管锅炉本体没有接受环泵施加的压力,但锅炉每时每刻都接受着高位贮水箱供给的热水静压力,楼层越高,热水静压力就越高。
    The atmospheric pressure hot water boiler is installed on the first floor or basement, and the hot water storage tank is installed on the roof. This method also uses the exhaust pipe connected with the atmosphere on the boiler body as a return pipe. Although the main body of the boiler does not accept the pressure exerted by the ring pump, the boiler always receives the hydrostatic pressure supplied by the high storage tank. The higher the floor, the higher the hydrostatic pressure of the hot water.
    常压热水锅炉本体上装置的排汽管口径过小,有的排汽管口径仅为Ф20mm,不能迅速地将炉内发生的蒸汽排放掉,使锅炉本体接受必定压力而存在必定的危险性。查验中发现一台常压热水锅炉的额外功率为30万大卡,本体上的排汽管为Ф20mm时,因排放才能缺乏,炉内发生的蒸汽压力可达0.15Mpa。锅炉的额外热功率越大,炉内发生的蒸汽压力就越大,危险性也就越大。
    The diameter of the exhaust pipe installed on the main body of the atmospheric hot water boiler is too small, and some of the diameter of the exhaust pipe is only 20mm, which can not quickly discharge the steam generated in the furnace, so that the boiler body accepts the necessary pressure and there is a certain danger. During the inspection, it was found that the extra power of an atmospheric hot water boiler is 300,000 calories. When the exhaust pipe on the main body is 20 mm, the steam pressure in the furnace can reach 0.15 Mpa due to the lack of exhaust capacity. The greater the additional thermal power of the boiler, the greater the steam pressure in the furnace and the greater the risk.
    将常压热水锅炉改为蒸汽锅炉运用,即将锅炉本体上与大气相通的排汽管直接装置在用汽的装置上面,并在排汽管上装置了操控阀门;也有的在排汽管上装置操控阀门后,直接从锅炉内取用开水或放热水洗澡,这是极不安全的。假如锅炉在运转中关掉了操控阀门,在压力不断升高的状况下,常压热水锅炉极易发生爆破,后果不堪设想。
    Changing the atmospheric hot water boiler to steam boiler is to install the exhaust pipe connected with the atmosphere directly on the steam-using device, and to install the control valve on the exhaust pipe. Others install the control valve on the exhaust pipe and take boiled water or hot water directly from the boiler for bathing, which is extremely unsafe. . If the control valve is turned off in the operation of the boiler, under the condition of increasing pressure, the atmospheric pressure hot water boiler is prone to burst, and the consequences are unimaginable.

    2.质量差,发展缓慢

    2. poor quality and slow development
    常压热水锅炉制作厂发展迅速,呈现了产品供大于求的状况,有的生产厂家技能力量薄弱,制作质量差,且各厂家之间竞赛十分剧烈,相互压价,有的厂家乃至偷工减料。
    Atmospheric pressure hot water boiler factories have developed rapidly, presenting the situation that the supply of products exceeds the demand. Some factories have weak skills and poor production quality. Competition among factories is fierce, and prices are reduced. Some factories even cut corners.
    规划不标准。常压热水锅炉与承压锅炉比较,有明显的特色,特别是在热力和水动力方面,因而常压热水锅炉的结构规划应契合其自身的特色。但目前常压热水锅炉规划还不标准,规划时底子不进行热力核算和水动力核算,常压热水锅炉的规划基本上是在承压锅炉的基础上改为开口方式罢了,其它结构原样仿制,致使锅炉水循环不良,糟蹋动力。
    Planning is not standard. Compared with pressure boilers, atmospheric hot water boilers have obvious characteristics, especially in terms of heat and hydrodynamics. Therefore, the structural planning of atmospheric hot water boilers should conform to their own characteristics. But at present, the planning of atmospheric pressure hot water boiler is not standard. Thermal and hydrodynamic accounting is not carried out at the base of planning. The planning of atmospheric pressure hot water boiler is basically based on pressure boiler and changed to open mode. The original structure of other boilers is imitated, resulting in poor water circulation and waste of power.
    生产技能力量薄弱,制作质量差。据有关材料显现有的制作厂的技能力量十分薄弱,有的厂家竟然没有一个锅炉专业技能人员,对常压热水锅炉自身的理论一知半解。有的底子没有规划材料、查验材料,有的厂家仅有抄袭而来的承压热水锅炉图纸,把其改为开口即成。因而导致锅炉制作质量低质,带来了事端隐患。
    The production skill is weak and the production quality is poor. According to the relevant materials, the existing manufacturing plants have very weak skills. Some manufacturers even do not have a boiler professional skilled personnel. They have a half-understanding of the theory of atmospheric hot water boilers themselves. Some bottoms have no planning materials and inspection materials, while others have only copied drawings of pressurized hot water boilers, which can be changed into openings. As a result, the quality of boiler production is low and brings hidden trouble.
    装置紊乱。近年来从事常压热水锅炉装置的部队越来越多,装置部队复杂,装置质量难于操控。锅炉房方位挑选与施工也十分紊乱,有的还未按《锅炉房规划标准》进行规划和施工。
    The device is in disorder. In recent years, there are more and more troops engaged in the atmospheric pressure hot water boiler device, which is complex and difficult to control. The selection and construction of boiler room orientation are also very disordered, and some of them have not been planned and constructed according to the "Planning Standard for Boiler Room".
