Abstract
A method and apparatus for the continuous baking of preheating, burning and cooling of carbonaceous moldings, which comprises burning fuels at the side and bottom portions of saggers which are charged with breeze and carbonaceous moldings to be baked; movably arranging a MOBAC [Mobile Baking Chamber] beneath a fixed ceiling having a combustion device and a gas recirculation system, in which MOBAC a baking chamber and a gas flue of refractory material are provided which pass combustion gas, heating gas or cooling gas; sealing the space between the fixed ceiling and the MOBAC and the upper contact surface of each MOBAC from atmospheric air; and connecting a number of said MOBAC in a row and moving them beneath the fixed ceiling.
Claims15
A method for the continuous baking of preheating, burning and cooling of carbonaceous moldings, which comprises charging, with carbonaceous moldings to be baked and breeze, a mobile baking chamber provided with a combustion chamber and a gas flue through which combustion gas, heating gas or cooling air passes, sealing from the atmospheric air the space between a fixed ceiling having a combustion means and a gas recirculation means and said mobile baking chamber, and the upper contact surface of intermobile baking chamber, and connecting a number of said mobile baking chamber in a row for movement beneath the fixed ceiling.
An apparatus for the continuous baking of carbonaceous moldings comprising a mobile baking chamber, a fixed ceiling and outside heat-retaining side walls, said mobile baking chamber having side surfaces and sealing material at the upper portions of front and rear surfaces of said mobile baking chamber, a number of said mobile baking chamber being connected together in series, said fixed ceiling having side surfaces and extending over the whole length of the upper portions of said connected mobile baking chambers, a slidable seal mechanism connected between and sealing the upper portions of the side surfaces of said mobile baking chambers and the side surface of said fixed ceiling so as to form an upper gas flue between the upper surfaces of said mobile baking chambers and said ceiling, said side surfaces of said mobile baking chamber including outside heat-retaining walls spaced from said outside heat-retaining side walls, said outside heat-retaining side walls having upper portions connected with said fixed ceiling, and a second slidable seal mechanism connected between and sealing the lower portions of said outside heat-retaining side walls and said outside heat-retaining walls of said mobile baking chambers thereby forming a heat-retaining space therebetween.
