Flow Distributions in Boiler Downcomer Cages

Abstract

The factors affecting the flow rate distribution in boiler downcomer cages are discussed and data on entry loss coefficients for downcomer offtakes presented. A rapidly converging computational technique has been devised for the calculation of the flow distributions in downcomer cages which has wider application in the field of pipe networks. The predictions of the network computations have been tested against plant data and found to be in good agreement.
