Reengineering the cyclone separator
Metal Finishing, 1998Summary The future of color change and color contamination will always be a big concern in the powder coating industry. Improvements in cyclone recovery systems, as well as booth design and application equipment, are continuously being sought. Available space, cost, ease of operation, and maintenance all must be taken into consideration during the ...

Optimum design of cyclone separator
AIChE Journal, 2009AbstractCyclone separators are one of the most widely used gas‐solid separators. Although the optimal design of cyclone separators has been suggested earlier, the earlier works do not include all the critical parameters responsible for minimizing the pressure drop which is quite decisive to obtain a correct optimal design.

In the previous chapter we have examined various models for predicting the velocity distributions in cyclones. In this chapter we wish to first present a brief discussion of the issues, and to then present some of the literature models available for computing cyclone separation efficiency.

Similitude in cyclone separators
Powder Technology, 2016Criteria for similitude in reverse flow cyclone separators are developed in this paper explicitly including the inlet particulate probability distribution. The application of these criteria is demonstrated by example using data from the literature. Some practical points to consider when using cyclone similarity relations are presented in the Conclusion.

Flow simulation in industrial cyclone separator
Advances in Engineering Software, 2010The problem of ash settling on super-heater tube bank, due to improper velocity distribution, in the cyclone separator used at Circulating Fluidized Bed Combustion (CFBC) has been investigated by means of computational fluid dynamic techniques. With the help of Computational Aided Design (CAD) software packages, the geometries of recycling cyclone, has

Described is a cyclone separator with a separation chamber (9) in a spiral housing (1) fitted with an inlet (3), disposed parallel to a tangent to the housing, for the material to be separated, as well as a separate, tangential inlet for the separator gas, plus a longitudinal outlet (7), disposed concentrically with the separator axis (6), to allow the

Hydrodynamic Studies on a Cyclonic Separator
Offshore Technology Conference, 1996Abstract The paper describes the operational principles, the modeling foundations and some laboratory results of the gas-liquid separation process taking place within a cyclonic gas-oil separator. The centrifugal and the gravity forces, acting on the flow of the gas-liquid mixture, are the main driving mechanism to ...

A Down-Exhaust Cyclone Separator
Industrial & Engineering Chemistry Research, 1999In this paper we report on the development of a down-exhaust cyclone separator suitable for use as a primary device for gas−particle separation in circulating fluidized-bed (CFB) boilers. It consists of a cylindrical shell which is joined by an inclined cone, a guide body, and a downward exhaust pipe.

Electrostatically enhanced cyclone separators
Powder Technology, 1982Abstract The separative performance of a cyclone can be enhanced if electrical forces are employed to supplement the inertial forces. By precharging the particles and applying a radial electric field within the cyclone, collection efficiency is improved. In the present paper, a model is developed for such an electrostatically augmented cyclone.

Collection efficiency of cyclone separators
AIChE Journal, 1981AbstractBased on terLinden's (A. J. terLinden, “Investigations into Cyclone Dust Collectors,” IME Proc., 160, 233, 1949) experimental observations, a three‐region model is proposed for the fluid flow in a cyclone. Within each region, turbulence is assumed to promote mixing of the suspended particles.
