    使用蒸汽锅炉的目的就是为了产生蒸汽,用以进行供热,但当蒸汽锅炉产生蒸汽之后不应该就不管设备了,还是要多加注意的,因为这时候蒸汽锅炉会开始升压,与此同时炉水的饱和温度也开始不断的提升。
    The purpose of using a steam boiler is to produce steam for heating, but when steam boiler produces steam, it should not be done regardless of the equipment, or more attention should be paid, because the steam boiler will start to boost the pressure and the saturation temperature of the furnace water begins to increase.

    由于蒸汽锅炉内的水温度不断升高,气泡和蒸发受热面的金属壁温也开始随时升高,需要注意热膨胀和热应力的温度,由于气泡的壁厚比较厚,在锅炉升温过程中的最主要的问题是热应力。
    As the temperature of the water in the steam boiler rises continuously, the temperature of the metal wall of the bubble and the evaporation surface begins to rise at any time. It is necessary to pay attention to the thermal expansion and the temperature of the thermal stress. Because of the thicker wall thickness of the bubble, the most important problem in the process of heating up the boiler is the thermal stress.
    同时,还要考虑其整体的热膨胀问题,尤其是对于蒸汽锅炉受热面的管子,因为壁厚薄、长度长,在升温过程中的问题是整体对的热膨胀,同时也要注意其热应力,防止因忽视而引发故障。
    At the same time, we should consider the whole thermal expansion problem, especially for the tube of steam boiler heating surface. Because the wall thickness and length are long, the problem in the process of heating is the thermal expansion of the whole pair. Meanwhile, the thermal stress should be paid attention to, so as to prevent the failure due to neglect.
    在蒸汽锅炉产生蒸汽并升温升压过程中,气泡存在着沿壁厚的温差及上下壁面间的温差,在内壁温度高于外壁温度,上部壁面温度高于下部情况时,为了防止产生过大的热应力,一定要对锅炉进行缓慢升压。
    In the process of steam boiler steam and rising pressure rising pressure, the bubble exists the temperature difference along the wall thickness and the temperature difference between the upper and lower walls. When the temperature of the inner wall is higher than the outer wall temperature and the upper wall temperature is higher than the lower case, the boiler must be slowly boosted in order to prevent the excessive thermal stress.
    而蒸汽锅炉在进行点火升压过程中,锅炉的蒸汽参数,水位以及各部件的工作状况也是在不断变化。所以,为了能够有效的防止异常情况以及其他危险事故的发生,一定要安排专业的工作人员,严密监视各种仪表指示的变化。
    In the process of ignition and boosting of steam boilers, the steam parameters, water level and working conditions of components are constantly changing. Therefore, in order to effectively prevent abnormal situation and other dangerous accidents, we must arrange professional staff and closely monitor the changes of various instrument instructions.
    通过调整控制压力、温度、水位等一些工艺参数在正常允许的范围之内,同时也要考核各种仪表、阀门等零部件的可靠性、安全性,这样才能充分的确保蒸汽锅炉的安全稳定运行。
    Through adjusting the control pressure, temperature, water level and other technical parameters in the normal range, and also to assess the reliability and safety of various instruments, valves and other parts, so that the safe and stable operation of the steam boiler can be fully ensured.
    从上述分析可知,并不是蒸汽锅炉出来蒸汽就可以了,还要考虑它的热应力、热胖张、升温、升压等问题,尽可能排除聚氨酯制品一切有可能会不利于设备安全的因素。
    From the above analysis, it is not possible to steam steam boiler out of steam, but also to consider its thermal stress, hot fat, heating, rising pressure and other problems, as far as possible to eliminate all the factors that may be harmful to the safety of the polyurethane products.
