Description

The objective of this project is to apply the gravel bucket pressure letdown concept to a stream of hot, gas-borne ash, under conditions similar to those found in a pressurized fluidized-bed combustor, where the system pressure is dissipated across a packed or partially fluidized bed of coarsely crushed rock. A second objective is to use the data collected during testing to develop a mathematical model which can be used to predict pressure drop in a gravel bucket device. The final objective of the project is to develop an economic analysis comparing the cost of constructing and operating a gravel bucket … continued below

A second objective is to use the data collected during testing to develop a mathematical model which can be used to predict pressure drop in a gravel bucket device. The final objective of the project is to develop an economic analysis comparing the cost of constructing and operating a gravel bucket with that of a lockhopper system. The results of this analysis will be submitted as a separate report. 9 refs., 6 figs., 5 tabs.
