要使碳氢燃油在常规燃烧循环中高效燃烧,需要非常高的温度,化学循环燃烧可以为大型动力装置提供一个可行的方法。在化学循环燃烧中,使用含氧介质分子来传输两个氧化还原反应之间的氧气,含氧介质在一个反应中被氧化,在另一个与燃油的反应中被减少。从燃烧残余物中分离出含氧介质可以借助于不同的物态,如果介质用钠、钾或锌,这是液态化学循环燃烧的显著优点。液态化学循环燃烧的原理是能量和熵的循环,在考虑用于分离氮和二氧化碳零部件效率、结合水燃气交换、以及用空气作为氧气源的情况下,高的热效率(35Pa下约75%)在理论上可以达到。
For hydrocarbon fuel to burn efficiently in conventional combustion cycles, very high temperatures are required and chemical cycle combustion can provide a viable solution for large power plants. In chemical cycle combustion oxygen containing media molecules are used to transport oxygen between two redox reactions that are oxidized in one reaction and decreased in the other reaction with the fuel. The separation of the oxygen-containing medium from the combustion residues can take advantage of different physico-chemical states, which is a significant advantage of the liquid-chemical cycle combustion if the medium is sodium, potassium or zinc. The principle of liquid chemical cycle combustion is the cycle of energy and entropy with high thermal efficiency (about 75% at 35 Pa), taking into account the efficiency for separating nitrogen and carbon dioxide components, the water-gas exchange, and the use of air as the oxygen source, In theory can be achieved.
