Successful Field Performance of a Heatset Web Offset Environmentally Compliant Dryer without Remote Incineration

Previous drying systems in heatset web offset required the use of a remote incinerator. The equipment discussed here uses products of combustion of incinerated ink oils as the heat source for the drying process. This is accomplished with only a single burner located within the dryer. Conventional technology uses large remotely located incinerators having separate combustion chambers, burners, fans, dampers, and heat exchangers. Results of dynamic performance tests of a new dryer in a production environment are discussed and include quantification of exhaust gas constituents and fuel usage as compared to conventional equipment. Operating characteristics and system heat and mass balance are also discussed.
