New Energy Recovery Pilot Coke Oven Concept and Design
Interest in Heat Recovery Coke Oven(HRCO)usage and processes has increased due to their improved environmental performance and ability to use a wide range of metallurgical and non-coking coals.To better understand the HRCO process,the Canadian Carbonization Research Association(CCRA)embarked on a program to construct a pilot-scale HRCO.Hatch completed the design of this unique pilot oven needed to reproduce the industrial scale HRCO heating profile and coal charge,and to minimize coal heating edge effect.Different aspects of the pilot coke oven design concept are presented,including oven geometry and wall insulation design,heating strategy using electric heaters,structural buckstay and oven door designs.Several 2D and 3D thermal transient finite element analyses were carried out to calculate the temperature profile of the coal/coke bed and oven walls during coking,capturing the thermal nonlinear behavior of the coal and oven wall bricks and to size the coal bed insulation for minimum edge heating effect.The structural stability of the oven arches was achieved using a spring loaded buckstay for lateral support and expansion allowance.The pilot oven,referred to as the Energy Recovery Coke Oven(ERCO),is being constructed at the CanmetENERGY Laboratory in Ottawa,Canada.
