Hazard Analysis Study for Low-Btu Gasification of Coal for Electric Power Generation. Phase 1. Final Report R and D Task 5,February 1975--August 1976.

摘要

A hazard analysis study was conducted for Combustion Engineering's 5ton-per-hour process development unit (PDU) and for projected commercial-scale versions of the C-E process for converting coal into a low-btu fuel gas. The study was oriented primarily to consideration of the unique features of the C-E process. Performance of the study required assembly,interpretation and application of available data on the flammability,ignition characteristics and toxicity of gases and gas/dust mixtures. Development of the comparative hazards of the C-E process with respect to the above characteristics,as contrasted to the known hazards associated with coal-fired steam generators or with other synthetic gas-making processes,was a central part of the study. Specific recommendations are made for protective systems,devices and procedures for the PDU and for commercial-scale plants. Included are discussions of alternate solutions for commercial-scale plants as may be appropriate for economic or technical reasons. In general,the recommendations were based on an engineering approach to each postulated hazard,combining logical analysis with economic considerations. (ERA citation 03:016375)
