The cyclone combustion chamber. Here the air is injected tangentially into a usually cylindrical chamber and exhausts through a centrally located exit hole at one end. The cyclone combustors are usually used to bum eflBciently diflBcult-buming materials such as high-ash-content and brown coals, anthracite, high-sulFur-content oils, damp vegetable refuse, poor-quahty-low-calorific-value fuels, etc. 

The momentum of the gas is better conserved using the tangential gas inlet. When the gas enters through the tangential gas inlet, the momentum of the horizontally flowing gas is efficiently converted to cyclonic flow in the body of the filter. On the other hand, when the gas is injected perpendicularly into the filter, the gas loses momentum as the flow is rearranged. 

Cyclone mixers can be made by focused injection of the fluids to be mixed in radial and tangential streams. Hardt et al. [77] have produced a CFD model of this type of mixer and optically verified its performance (Fig. 7.5). 

The venturi scrubber usually consists of a venturi contactor followed by a cyclone separator. The particle-laden gas flows downward to the approach section of the venturi, where water is injected tangentially to flood the wall. After achieving intimate contact of the particles with the liquid in the throat of the venturi, the stream then turns and enters the cyclone where clean gas leaves at the top and a slurry leaves at the bottom. Venturi scrubbers are particularly effective at high concentrations of particles.
