Alternatives to Natural Gas in Metal-Coil Coating. Final Report, September 27, 1978-December 15, 1981

摘要

A program to investigate the need of coil coaters for a viable alternate energy form (i.e., clean, easy to use, and available) when natural gas use by industry is curtailed is described. Heretofore, control of emissions of coating solvents required fossil fuel for incineration. During this program, an electric alternative to the use of natural gas in metal coil coating was developed, based on the INERTAIR process supplemented by electrical heating. The essential features of the improved INERTAIR process are: an incinerator that uses electrically heated air in burning solvents evaporated in the coil coating line, but does not use natural gas; and an INERTAIR process in which the incinerated gases are returned to the oven to provide the process heat as well as provide an inert atmosphere for safe operation of the oven. This technology has been proved feasible through bench scale development testing conducted under this program. Scaling data needed for designing large size components of an operational coil coating line have been obtained. The design of a laboratory facility to demonstrate the electric alternative to natural gas in metal coil coating has been completed. (ERA citation 07:044044)
