Experience of lime kiln ringing problems at E.B. Eddy Forest Products (original) (raw)
MAINTENANCE lmproved mud-washing and flocculents bring ringing under control BY H. TRAN, J. GRIFFITHS, AND ItI. BUDGE NVIRONMENTAL REGULATIONS ON malodorous gas emissions from pulp mills have become stricter in recent years. As a result, lime kilns are increasingly used to burn and destroy non-condensible gases (NCG) and total reduced-sulphur compounds (TRS) from kiln ringing problems recovery processes. The practice has long been suspected as a source of ringing problems in lime kilns []. Industry-wide experience, however, has varied. Not all NCG-burning kilns have experienced severe ringing problems. A special meeting, Ringformation in lime kilns burning NCG, was held in January of 1988 by the National Council of Pulp and Paper for Air and Stream Improvement in Atlanta. There was considerable debate among the 67 participants from 19 American pulp mills as to whether NCG combustion is the prime cause of ringing. This paper describes the experience of ringing problems, and the measures taken to minimize them at E.B. Eddy Forest Products' IlOG adtld bleached kraft pulp mill in Espanola, Ontario.
