20100170299 | METHOD AND APPARATUS FOR THE PRODUCTION OF MAN-MADE VITREOUS FIBRE PRODUCTS - A non-woven product having a core layer ( | 07-08-2010 |
20110232333 | PROCESS AND APPARATUS FOR MAKING MINERAL FIBRES - A process for making a mineral melt comprising: providing a circulating combustion chamber which contains circulating chamber gases, injecting a stream of particulate fuel into the combustion chamber through a fuel feed pipe, injecting combustion gas into the combustion chamber; mixing the stream of particulate fuel with the combustion gas and with the circulating chamber gases by injecting into the combustion chamber secondary gas, through a secondary gas inlet, wherein the secondary gas is injected adjacent to the stream of particulate fuel and the injection speed of the secondary gas is at least 100 m/s greater than the injection speed of the particulate fuel; suspending particulate mineral material in the circulating chamber gases and combusting the fuel, thereby melting the particulate mineral material and forming a mineral melt and hot exhaust gases; and separating the hot exhaust gases from the melt and collecting the melt. | 09-29-2011 |
20130186149 | APPARATUS AND METHOD FOR MAKING A MINERAL MELT - An apparatus for the production of a mineral melt burns combustible material in the presence of inorganic particulate material to form a melt. The apparatus has a circulating combustion chamber having at least two inlets which receive fuel, pre-heated mineral material, and combustion gas. A heat exchange system for pre-heating the mineral material has a pre-heater cyclone, a conduit running from the circulating combustion chamber to the first pre-heater cyclone for transporting exhaust gases, a material inlet for injecting the material into the conduit, and a bottom cyclone outlet for feeding pre-heated mineral material to the combustion chamber. The outlet of the pre-heater cyclone stabilizes and splits the mineral material flow into two material flows for feeding combustion chamber inlets. | 07-25-2013 |
20130199245 | METHOD AND AN APPARATUS FOR MAKING A MINERAL MELT - An apparatus for the production of a mineral melt burns combustible material in the presence of inorganic material to form a melt. The apparatus includes a circulating combustion chamber which receives a fuel, pre-heated mineral material and a combustion gas, melts the mineral material and generates exhaust gases which are separated from the melt. The gases pass through an exhaust pipe to a conduit of a heat exchange system. The apparatus includes a quenching hood for quenching the exhaust gases by drafting a cooling fluid, such as ambient air, into the flow of exhaust gases around the exhaust pipe, and wherein the exhaust gases exit the exhaust pipe inside the hood. | 08-08-2013 |
20140311184 | METHOD FOR RECYCLING MATERIAL WHEN MAKING A MINERAL MELT - The present invention concerns a method of making a mineral melt by burning combustible material in the presence of inorganic particulate material and thereby forming a melt, comprising injecting fuel, particulate mineral material and combustion gas into a circulating combustion chamber ( | 10-23-2014 |
20140345715 | TRICKLE VALVE ASSEMBLY AND A METHOD OF SUPPLYING PARTICULATE MATERIAL THROUGH SUCH TRICKLE VALVE ASSEMBLY - The present invention concerns a trickle valve assembly for supplying particulate material exiting the bottom of a separating cyclone, comprising a separating cyclone outlet conduit having a bottom end with an inclined valve seat and a pivotable valve plate assembly with a valve plate pivoting about a valve hinge and a counter-weight on the opposite side of said valve hinge, wherein the outlet conduit is provided with at least one gas inlet above the inclined valve seat which is in fluid communication with a supply of pressurised gas, such as a pressurised air supply. | 11-27-2014 |
