Definitions
- my present invention I provide a process in which additional heat is recovered and utilized, making it possible to decrease the heating surface required in certain of the heat exchangers and, therefore, reducing the cost of these eX- changers which are generally made of expensive corrosion resisting metals.
- air is compressed in a compressor I and ammonia is compressed in a compressor 2, and the mixture may then be ture to, for example, 850 C.
- the hot gases areY then passed first through the heat exchanger 5 in which they heat the residual gases to be supplied to the compressing apparatus I, and thence through a heat exchanger 3 in which heat is given up to the air and ammonia mixture passing to the combustion chamber.
