Eco-friendly Industrial Cyclone Separator With High Speed Rotating Air Flow cyclone air separator

CYCLONE SEPARATOR APPLICATIONS

1. Mechanical collectors were adequate when the emissions regulations were less stringent and were used when firing techniques produced larger particles.

2. These were frequently used for re injection to improve unit efficiency on stoker firing of coal and biomass. 3. Due to strict emission regulations mechanical collectors can no longer be used as the primary control device.

Abstract

1. Cyclones are the most common dust-removal systems used in combined cycle fluidized bed combustion boilers. Analysis of a cyclone separator combining flow and structural aspects is carried out using detailed three dimensional finite element modeling including stiffeners and supporting arrangement. The fluid flow study involves the solution of continuity, energy and Navier-Stokes equations.

2. The fluid analysis gives the variation of pressure on cyclone shell, which in turn is imparted on the structural model using fluid structure interface routine. The pressure distribution obtained from the fluid-flow analysis is mapped on to the structure. Then a linear static analysis is performed considering thermal, wind and seismic loads besides the pressure loads. The results for various loads include the reaction forces at the supports and stress levels in the cyclone. The stresses are checked against the allowable values as per Indian Standard Structural Codes.

3. A separate computer code is developed and is interfaced with the FEM program. Results indicate higher stresses in some of the beam stiffeners and at support locations. These are suitably modified and a reanalysis confirmed the stresses to be within limits. The analysis methodology combining the fluid, structure and code requirement developed shall be very useful for the design improvement and safe operation of a cyclone separator.
