主题:燃气热风炉的运行时间以及导热系数 [收藏主题] |
燃气热风炉在经过其长时间的运行,在使用的过程中不可避免会出现其水垢以及锈蚀的问题,燃气热风炉中形成其水垢的主要的原因是因为给水中带有硬度成份,经过高温、高压的不断蒸发浓缩。 After a long period of operation, scaling and rust will inevitably occur in the process of using the gas hot blast stove. The main reason for scaling in the gas hot blast stove is that the hardness component in the feed water is continuously evaporated and concentrated through high temperature and high pressure. 燃气热风炉在运行时其炉内会发生其一系列的化学以及物理的反应,在使用的过程中最终会在受热面上有效的形成其坚硬以及致密的水垢,这样就会直接导致其换热效率降低且因垢下腐蚀因素,会导致热风炉水冷壁炉膛吸热减少。 A series of chemical and physical reactions will take place in the gas hot blast stove when it is running. In the process of using, the hard and dense scale will be formed on the heating surface effectively, which will directly lead to the reduction of heat transfer efficiency and corrosion factors under the scale, which will lead to the reduction of heat absorption in the water-cooled wall furnace of the hot blast stove. Less. 燃气热风炉的炉膛的出口温度在进行增加的过程中,这样就会使得热风炉的损失增加,设备中水冷壁内的结垢后会有效的使其传热效果减少,这样就非常有可能会导致水冷壁管壁温度增加导致水冷壁爆管 In the process of increasing the outlet temperature of the gas-fired hot blast stove, the loss of the hot blast stove will be increased, and the scaling in the water wall of the equipment will effectively reduce its heat transfer effect, which will very likely lead to the increase of the wall temperature of the water wall and the bursting of the water wall. 燃气热风炉的水垢的导热系数在运行时只有钢材的几十分之一,当其受热面结垢后,这样就会使得传热效果受到阻碍,在使用的过程中为了保持热风炉一定的出力,就必须提高火侧的温度。 The thermal conductivity of scale in gas-fired hot-blast stove is only one-tenth of that of steel in operation. When the heating surface of gas-fired hot-blast stove scales, the heat transfer effect will be hindered. In order to maintain a certain output of hot-blast stove in use, the temperature on the fire side must be raised. 燃气热风炉在进行清洗的过程中可以采用其高效且环保无腐蚀的清洗剂来对热风炉进行清洗,这样就会使得设备列管露出金属原色,降低因为结垢及生物藻类淤泥的影响。 Gas-fired hot stove can be cleaned by its efficient and environmentally friendly non-corrosive cleaning agent in the process of cleaning, which will make the pipes of equipment expose metal primary color and reduce the impact of scaling and biological algae sludge. 燃气热风炉在进行点火以后需要有效的注意观察其炉膛烟温以及主蒸汽的温度,其主蒸汽的压力的上升的情况,遇到热风炉点火后其烟温就会上升的速度明显偏慢或烟温不上升要立即去就地检查油枪的着火情况。 After ignition, it is necessary to observe the flue gas temperature and the temperature of the main steam, and the pressure rise of the main steam. When the hot air stove is ignited, the smoke temperature will rise slowly or the smoke temperature will not rise, so it is necessary to inspect the ignition of the oil gun in situ immediately. |
