The hot air furnace is a kind of energy conservation type furnace, composed of burner, furnace chamber, mixing room, hot air outlet and outside jacket, the diluted air in the jacket has two functions, firstly, having insulation purpose: the air belongs to inert gas, it has good insulation function for furnace body, can reach to purpose to cool/protect inside lining and reduce its thickness of furnace chamber; secondly, having preheating function: the gas in the jacket is contacted with hige temperature furnace wall, and enters the mixing room after heat absorption, then to teach the purpose of preheating and energy conservation.

热风炉由燃烧器、炉膛、混合室、热风出口和外夹套构成，是一种节能型炉型，夹套中的稀释空气有两种作用，其一，保温作用：空气属惰性气体类，对炉体有良好的保温作用，达到冷却保护和减薄炉膛内衬的目的；其二，预热作用：气体在夹套中与高温炉壁相接触，吸热后进入混合室，达到了预热节能的目的。

The effects of preheating on temperature and stress fields of beryllium ring during laser brazing process were studied.

研究预热对铍环激光束钎焊过程温度场和应力场分布的影响。

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。

Preheating shall also be applied to the tack welding, when the weldment requires preheating.

c 需要预热的焊件，定位焊时也应按规定进行预热。

Any preheating and precooling increases the chamber charging pressure before TDC, and this is mechanically counter- productive for the piston (gas chamber loading requires less mechanical energy in the absence of preheating and precooling, which makes the regenerator less effective than one may think).

任何预热和预冷室收费增加了贸发局的压力面前，这是机械计数器加载生产的活塞（气室需要一个可能觉得少的机械比能量的情况下预热和预冷，这使得再生效果较差）。

Low-voltage high-pressure Dianre Tan Dian Retan than the advantages of low-voltage high-pressure Dianre Tan Dianre Tan is not conductive, bedwetting children are not afraid of a water leakage and the risk of electric shock without preheating, only a bed, and immediately warming up ahead of 30 to 60 minutes preheating , Prolonged use can slow warming, for 72 hours.

低压电热毯比高压电热毯的优势不导电，小孩尿床都不怕有水会漏电及触电的危险不需预热，上床才开电，马上升温提前30~60分钟预热，升温慢可长时间使用，连续72个小时。

Rapid drying and high quality were obtained in the bamboo shoots of thinner cut with preheating and high temperature, and high rehydrating rates were obtained in the products of thinner cut with high temperature and no preheating.

结果表明，切分厚度薄且经漂烫，干燥温度高的毛竹笋干燥速度快，制品感官质量好；切分厚度薄且未经漂烫，干燥温度高的制品复重率高。

And then some"equivalent parameters"of hot stoves with self-preheating process were submitted and the eigenfunctions of heat exchange in the condition of self-preheating process were determined.

在前人自身预热操作法的基础上，进行了深入的理论研究，完成了包括大型高炉热风炉自身预热工艺流程、各参数对比分析和陶瓷燃烧器等配套技术等系统应用研究。
