Power boiler air preheater hot spots detection system is a indispensable installation which are applied in power plant largely.

电站锅炉空气预热器是广泛应用于火力发电厂的不可缺少的设备，但是由于其自身的工作特性所决定，空气预热器比较容易起火。

It is very important problem how to detect aggregate fuels and sediments temperature on air preheater parts surface effectively in order to prevent air preheater from fire.

如何有效地检测空气预热器表面的燃料油污沉积物的温度，是防止空气预热器表面起火所必须考虑的问题。

It is shown that the effect of dynamic thermal tensioning by trailing intensive cooling is greatly influenced by the heat-dissipating conditions of the fixtures.Without uniform preheating it is difficult for trailing intensive cooling alone to create a saddle-shaped temperature field and the mechanism of reducing distortion is equivalent to the decrease of welding heat input. While combined with uniform preheating ,dynamic thermal tensioning comes into being to some degree and the effect of reducing distortion increases obviously.

研究表明，由随焊激冷造成的动态温差拉伸减小焊接变形的效果受夹具自身散热条件的影响较大：不采用整体预热时，难以造成马鞍形温度场，此时减小焊接变形的机理主要是焊接线能量的等效降低；采用整体预热后，能够造成一定程度的温差拉伸，减小焊接变形的效果明显提高。
