RESEARCH AND DEVELOPMENT OF HIGH TEMPERATURE PARTICULATE CLEANUP USING A MOVING GRANULAR BED FILTER AT THE TAIWAN INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE

摘要

In order to be cost effective and to improve energy efficiency, high temperature gas cleaning technologies are very prospective to develop. Moving granular bed filters are technically and economically applicable for high temperature gas cleaning systems. Nevertheless, stagnant zones of bed material may always exist that endanger the system operation. Energy and Resource Laboratories, Taiwan Industrial Technology Research Institute (ERL/ITRI) has been developing and testing a moving granular bed filter (MGBF) for high temperature gas cleanup. A simple flow pattern correction structure that modifies the granular flow pattern has been designed and tested successfully to eliminate the formation of stagnant zones. By connecting to an auxiliary dust/granule separation system, MGBF has been operated continuously at a stable pressure drop with a stable high efficiency.
