导热油在超出其热稳定性限制的条件下运用会发作快速热裂解，其热物理性质参数关于炉内传热效率和介质温度变化具有十分重要的影响。由于导热油的超温裂解会招致锅炉管结焦，恶化传热，引发炉管爆裂。
　　When the heat transfer oil is used beyond its thermal stability limit, it will undergo rapid thermal cracking. Its thermophysical property parameters have a very important influence on the heat transfer efficiency and medium temperature change in the furnace. Due to the over temperature cracking of the heat transfer oil, the coking of the boiler tube will be caused, the heat transfer will be deteriorated, and the furnace tube will burst.
　　形成导热油在炉膛内走漏熄灭，故导热油锅炉的设计应该满足所选用导热油的热稳定性条件，运用其热物性参数停止锅炉的传热计算、构造设计和平安评价，应防止在锅炉内部任务部位发作导热油过热超温的问题。
　　The heat transfer oil leakage in the furnace is formed, so the design of the heat transfer oil boiler should meet the thermal stability conditions of the selected heat transfer oil. The use of its thermal physical parameters to stop the heat transfer calculation, structural design and safety evaluation of the boiler should prevent the overheating of the heat transfer oil at the internal task position of the boiler.
　　锅炉受热面边境层内的导热油液膜温度应遭到严厉限制。锅炉设要依据所选用导热油的允许液膜温度，对炉膛内辐射受热面上的热流密度停止限制，并对炉管内导热油的流速及温度加以控制。此外，导热油锅炉的辐射受热面布置应当防止火焰对炉管的直接冲刷，由于锅炉运转时，假如炉膛内发作部分火焰直接冲刷炉管，将会招致该路管道额热流密度增大，并招致导热油液膜温度升高。

　　The liquid film temperature of heat transfer oil in the boundary layer of boiler heating surface should be strictly limited. During boiler design, the maximum heat flow density on the radiant heating surface in the furnace shall be limited according to the maximum allowable liquid film temperature of the selected heat transfer oil, and the flow rate and temperature of the heat transfer oil in the furnace tube shall be controlled. In addition, the layout of the radiation heating surface of the heat transfer oil boiler should prevent the direct erosion of the flame on the furnace tube. Because when the boiler is running, if part of the flame in the furnace directly washes the furnace tube, it will lead to the increase of the heat flow density of the pipeline and the rise of the temperature of the liquid film of the heat transfer oil.
　　导热油在锅炉内发作走漏会招致火灾或爆炸。引发导热油在锅炉内走漏的主要缘由是导热油结焦致使炉管过热爆裂、炉管焊接缺陷、或锅炉构造及炉管资料存在问题。一旦锅炉发作导热油走漏事故，如何尽快熄灭炉膛内熄灭的燃料并切断导热油和空气的供给便成为控制事故扩展和减小其危害水平的关键。
　　Leakage of heat transfer oil in boiler will cause fire or explosion. The main reason for the leakage of heat transfer oil in the boiler is that the coking of heat transfer oil causes the furnace tube to overheat and burst, the welding defect of the furnace tube, or the problem of the boiler structure and the furnace tube data. Once the leakage of heat transfer oil occurs in the boiler, how to extinguish the extinguished fuel in the furnace and cut off the supply of heat transfer oil and air as soon as possible becomes the key to control the expansion of the accident and reduce the hazard level.
