前言氨燃烧气氛在我国应用较晚。原因在于我国发展可控气氛的初期,对国内资源及成本缺乏认真的考查及研究。在学习国外先进经验方面带有盲目性,大量的投资及研究力量大都花费在吸热式气氛上。石油危机迫使国外放弃吸热式气氛而大力寻找其代用气氛,如氮基气氛。我国天然气及石油液化气的供应从开始发展可控气氛起就没有得到解决,至今更加困难,因此吸热式气氛的推广使用的希望极小。氨燃烧气氛国外资料却认为比吸热式气氛的成本高(约2～4倍),主要是由于液氨的价格大大高于天然气和石油液化气的价格。 Introduction ammonia combustion atmosphere in our country later. The reason is that in the initial stage of the development of a controlled atmosphere in our country, there was a lack of careful examination and study of domestic resources and costs. In learning advanced foreign experience with blindness, a large number of investment and research efforts are mostly spent in a heat-absorbing atmosphere. The oil crisis forced foreign countries to give up the heat-absorbing atmosphere and vigorously look for its alternative atmosphere, such as the nitrogen-based atmosphere. The supply of natural gas and liquefied petroleum gas in our country has not been solved since the beginning of the development of a controlled atmosphere and so far it has been even more difficult. Therefore, the hope of promoting the use of an endothermic atmosphere is extremely small. Ammonia Burning Atmosphere Foreign sources find the cost (about 2 to 4 times) higher than that of an endothermic atmosphere is mainly due to the fact that the price of liquefied ammonia is much higher than that of natural gas and liquefied petroleum gas.
