低碳氨发动机的研究

Study on low carbon ammonia engine

化石燃料的过度使用引发了一系列能源和环境问题,氨作为可再生环保燃料可有力缓解石油资源短缺的现状和改善大气环境。文章试验研究了氨气/液化气混合燃料发电机的性能和低碳处理效果。在改造汽油、液化气双燃料发电机组的基础上,研究了混合燃料中氨百分比逐渐增大时发动机性能的变化以及氨水装置对尾气的净化效果。研究结果表明,氨气/液化气混合燃料发电机在一定程度上可以保持其负载性能,氨气比例增加到一定值时,发电机的输出功率和电压会逐渐下降;氨发动机的尾气经过氨水装置后,二氧化碳的浓度可以降低到1%左右,实现低碳排放。

Overuse of fossil fuel has caused a series of energy and environmental problems. However, ammonia is a kind of renewable and environment-friendly fuel and it can greatly relieve shortage of petroleum resources and improve atmospheric environment. Study on performance of generator that runs on ammonia/LPG mixture fuel and its low carbon emission is put forward in this paper. The influence of various percent of ammonia and LPG mixture on engine performance is studied and the effect of ammonium hydroxide purification for emission reduction is investigated based on a reformed Gasoline/LPG dual fuel generator set. Experimental results showed that the engine with load could maintain its dynamic performance when the proportion of ammonia was small, however, as the proportion of ammonia increased to some extent, the generator power and voltage would decrease; meanwhile, the percentage of carbon dioxide would reduce to 1% when the engine emission was ventilated into ammonium hydroxide device, in this way the engine carbon emission was low.
