Embodiment Construction

[0012] The fuel-air mixing pressurization method of the present invention uses relatively high-pressure fuel to be injected along the tangential direction of the turbine blades installed in the cavity, and the kinetic energy of the fuel is transferred to the turbine to drive the turbine to rotate, and the air is sucked through the rotation of the turbine. While obtaining the kinetic energy transmitted by the turbine rotation, it is mixed with the fuel. Due to the centrifugal force, the mixed gas is ejected along the gas outlet on the cavity to form a mixed gas with a certain kinetic energy (or pressure).

[0013] See Figure 1.

[0014] The fluid mixing device is provided with a movable turbine 3 through a rotating shaft 4 in the air chamber, and a first fluid inlet 2, namely 3 nozzles, is arranged along the tangential direction of the turbine blades, and a second fluid inlet is arranged at the position of the rotating shaft 4, The gas chamber is provided with a mixed gas outle...

Abstract

The inventive fuel-air mixing and supercharging method includes the following steps: driving the turbine in the air chamber with high-pressure gas; intaking air into the air chamber with the negative pressure produced by the rotating of the turbine; forming the mixed gas with higher pressure after mixing with the gas and then being jetted from the outlet. The inventive combustion apparatus has an air chamber, in which is disposed a movable turbine through a rotation axis. Along the tangential direction of the turbine blade is disposed a first fluid inlet and in the position of the rotation axis is disposed a second fluid inlet. An outlet is disposed on the air chamber.

Description

technical field [0001] The present invention relates to fluid dynamics. Background technique [0002] The application of fluid mixing technology is very extensive. Taking gas as an example, if the gas and air are mixed uniformly before the gas is burned, sufficient combustion can be achieved. In the prior art, all rely on the natural mixing of gas and air in the air chamber, and its effect needs to be improved. [0003] The thermal efficiency of ordinary atmospheric gas appliances generally does not exceed 55%. The main reasons are as follows: [0004] The required air is mixed by diverting air through fuel injection, it is difficult to ensure sufficient mixing, and at the same time, the amount of air is obviously not enough to ensure combustion, so secondary air supplementation is required during combustion, often resulting in too much excess air , reducing the flame temperature also reduces the combustion efficiency. Contents of the invention [0005] The technical pr...
