A new way to combine the components of typical storage firing coal mill systems into a compact structure, saving on space, building cost, mill-to-dust collector and related duct lengths, rotating parts and explosion protection equipment.

by Vincent Grosskopf, Thorwesten Vent GmbH, Beckum, Germany

This presentation deals with the reduction of investment and operational cost by introducing innovative technological improvement in terms of both process- and safety related issues, combined. The improvement basically stems from building such plant in a more compact configuration, by integrating a number of beneficial design improvements on the way. Since the new configuration doesn’t ask for major changes in the process all key equipment of which coal mill systems consist, with the exception of the process filter and in some cases the min fan, will be used as usual.

Explosion vents are a protective means of last resort. How must the constructional protective technique explosion venting for silos in the industry be applied?

This publication describes explosion venting as one of the techniques of constructional explosion protection of silos and reaches the conclusion that experts don’t deal with fire and explosion protection as closely related issues. The differences between the use of self-reclosing and non-reclosing explosion vents are explained. And examples of non-justifiable differences in approach of silo related explosion protection which can be seen in different industries are given. The text originally was a contribution to the IVth International Symposium on Hazards, Prevention and Mitigation of Industrial Explosions held in Bourges, France, October 2002.

Explosion protection for coal grinding plant. What should really be done?

The text includes a compilation of the presently applicable guidelines for explosion protection by means of explosion venting, with reference to VDI 3673, NFPA 85 and NFPA 68. Title: Explosion protection for coal grinding plant. What should really be done? The paper was originally published as presentation for the AFCM 17th Symposium & Exhibition, June 2000, one of the established regular events for the cement industry. Summary: After showing the various difficulties with guideline compliance engineers will face a logical and practical approach is described.
