HC Deb 12 July 1991 vol 194 c500W
Mr. William Ross

To ask the Secretary of State for Northern Ireland whether the incinerator proposed for the Maydown, Londonderry site will be required to have gas/gas heat exchanges to maintain the stack gases well above the gas clear point.

Mr. Needham

Any combustion plant including an incinerator will be required to incorporate heat exchangers to ensure that the flue gas temperature does not fall below the acid dew point.
