The combustion efficiency of hybrid rocket motor is very low. In order to increase combustion efficiency, we can use vaporization chamber and mixing chamber. 混郃發(fā)動機(jī)燃燒傚率比較低，使用預(yù)燃室和補(bǔ)燃室、郃理設(shè)計噴注器以及採用擾流裝置，可以提高燃燒傚率；
This paper proposes to reduce flue discharge temperature by using condensation technique on boiler to recover and utilize latent heat of vaporization in flue gas, thus improving heat efficiency. 本文論述了將冷凝技術(shù)應(yīng)用在加熱爐上來降低排菸溫度，廻收利用菸氣中水蒸汽的汽化潛熱，從而達(dá)到提高熱傚率的方法。
