Abstract
A method for gasifying a combustible liquid or powder using a gas detonation wave including a step of introducing detonable mixed gas including oxidizing gas into a detonation tube, a step of spraying, coating or laying combustible liquid or powder in the detonation tube and a step of detonating the mixed gas by ignition so that the combustible liquid or powder is thermally decomposed by the high-temperature and high-pressure behind the detonation wave.
Claims4
A method for gasifying combustible liquid or powder using a gas detonation wave comprising:
- a step of introducing a detonable mixed gas comprising a uniform mixture of a combustible gas and an oxidizing gas into a detonation tube at a pressure equal to or greater than atmospheric pressure, said combustible gas and oxidizing gas being provided in amounts within a detonable range;
- a step of spraying, coating or laying the combustible liquid or powder in the detonation tube;
- and
- a step of only detonating said mixed gas by ignition to produce a supersonic detonation wave which propagates through the detonation tube to thermally decompose the combustible liquid or powder by high-temperature of at least 2000.degree. C. and high-pressure of at least 20 times atmospheric pressure behind the detonation wave.
A method for continuously gasifying combustible liquid or powder using a gas detonation wave comprising:
- an initial detonation cycle which includes:
- a step of introducing a detonable mixed gas comprising a uniform mixture of a combustible gas and an oxidizing gas into a detonation tube at a pressure equal to or greater than atmospheric pressure, said combustible gas and oxidizing gas being provided in amounts within a detonable range;
- a step of spraying, coating or laying the combustible liquid or powder in the detonation tube;
- a step of only detonating said mixed gas by ignition to produce a supersonic detonation wave to thermally decompose the combustible liquid or powder by high-temperature of at least 2000.degree. C. and high-pressure of at least 20 times atmospheric pressure behind the detonation wave;
- and
- a step of exhausting and collecting all but a part of decomposed gas produced by detonation by an over pressure inside the detonation tube;
- and
- a subsequent detonation cycle which includes:
- a step of introducing an oxidizing gas alone into the detonation tube to form a second detonable mixed gas with the part of decomposed gas in amounts within a detonable range;
- a step of spraying, coating or laying the combustible liquid or powder into the tube;
- and
- a step of only detonating said mixed gas by ignition to produce a supersonic detonation wave to thermally decompose the combustible liquid or powder by a high-temperature of at least 2000.degree. C. and high-pressure of at least 20 times atmospheric pressure behind the detonation wave.
