Double combustion chamber device for burning aluminum particles and water

Abstract

The invention relates to a double combustion chamber device for burning aluminum particles and water. The double combustion chamber device comprises a pre-combustion chamber and an afterburning chamber, wherein the pre-combustion chamber comprises four aluminum particle inlets which are uniformly distributed in the circumferential direction, one ignition starting inlet and four water vapor inletswhich are uniformly distributed in the circumferential direction; the steam tangentially enters the pre-combustion chamber to form a vortex flow, the aluminum particles enter the pre-combustion chamber along the axial direction and also form the vortex flow under the driving of the steam, and a steady-state high-temperature region is formed in the pre-combustion chamber to promote the subsequent aluminum particles to be successfully ignited after the initial ignition of the aluminum particles is successful; the afterburning chamber is provided with a plurality of water nozzles which are uniformly distributed in the circumference, the aluminum particles which are incompletely combusted enter the afterburning chamber and are subjected to supplementary combustion with liquid water injected into the water nozzle, and meanwhile, a large amount of water is added to the rear part of the afterburning chamber to increase the gas flow in the afterburning chamber and reduce the afterburning roomtemperature, and therefore the needed high-temperature and high-pressure mixed fuel gas is obtained for doing work. According to the double combustion chamber device for burning aluminum particles andwater, continuous and stable combustion of aluminum particles can be realized, the structure is simple, low in cost, high in aluminum particle burning efficiency and the like.

Description

technical field [0001] The invention relates to a combustion device used for a power system of an underwater vehicle, in particular to a dual combustion chamber device that uses aluminum and water to burn to generate power. Background technique [0002] At present, in the power system of the underwater vehicle, the actual specific energy of the power battery is not high, and due to the low theoretical specific energy, the actual specific energy increase space is limited; fuel cells and semi-fuel cells have high theoretical specific energy, but fuel cells High cost, poor reaction / start-up performance, and large negative mass brought by hydrogen storage limit its use in underwater power systems, while the use of semi-fuel cells requires complex auxiliary circulation systems and concentration maintenance devices. And the battery output power is small. In the thermal power system, the water ramjet uses high-energy water to react metal fuel with external seawater to generate thr...
