International Correspondence Scools' 'Coking' unit, 1907 edition, refers to
"Jameson's Process" as an improvement to conventional beehive coking ovens
by "recovery of certain by-products [oil & ammonia]". These were not
by-product ovens in the usual sense - just the fitting of drains below
otherwise virtually conventional beehives, from which I gather that
carbonisation was still brought about by the the partial combustion of the
coal in the oven, unlike true by-product ovens. Article goes on to state
plant adopted "many years ago in Durham district". It's the last that
interests me; does anybody know more specifically when & where it was
adopted & when ceased?
