Publication number: 20200071229Abstract: A method for producing an expanded granulate made of a sand grain-shaped mineral material uses a propellant. The material is transported along a transport path through multiple heating zones in a furnace shaft, heated to a critical temperature at which the surfaces of the sand grains plasticize, and the sand grains are expanded based on the propellant. The material is fed from the bottom together with an amount of air; the material is transported from the bottom to the top along the transport path by the air quantity which flows from the bottom to the top in the furnace shaft and the sand grains are expanded in the upper half of the transport path. The material is heated such that the material immediately prior to entering into the furnace shaft is at a material entry temperature lower than the critical temperature and higher than the ambient temperature.Type: ApplicationFiled: April 18, 2017Publication date: March 5, 2020Applicant: Binder + Co AGInventors: Ernst Erwin BRUNNMAIR, Gerhard SALCHINGER

Patent number: 6401636Abstract: A process for the incineration of particulate solids, especially biological waste matter with low caloric value, feeds the solids into a combustion chamber of a furnace together with a sub-stoichiometric amount of fresh air to control the rate of combustion and to inhibit the formation of sintered ash. The furnace for implementing the process can be a cyclone furnace having a primary combustion chamber with a first feed inlet for the solids and air and a second air inlet positioned between the first inlet and an exhaust gas outlet. A supply tube extends through the exhaust gas outlet of the primary combustion chamber to supply a source of fresh air at ambient temperature to maintain the primary combustion chamber at a desired temperature. The fresh air maintains the furnace temperature at least at about 850° C. and generally at about 850° C. to less than about 1100° C.Type: GrantFiled: February 28, 2001Date of Patent: June 11, 2002Assignee: Andritz-Patentverwaltungs-Gesellschaft mbHInventors: Erwin Brunnmair, Gerhard Moosmann
