  • Publication number: 20130205701
    Abstract: The invention relates to a heat insulation element for insulating building facades, in particular for heat insulation composite systems, composed of a heat insulating board and a reinforcement mesh that can be penetrated by fastening elements, in particular plugs, wherein the reinforcement mesh is placed in the area of a large surface of the heat insulating board. It is the object of the invention to avoid the disadvantages of the state of the art and in particular to provide a heat insulation element which even in case of high tightening torques of the fastening elements does not excessively tends to be deformed into the direction of the building facade. This a i m is achieved by a heat insulation element according to the invention, in which the reinforcement mesh is arranged as a component of an abutment at a distance to the surface of the heat insulating board and in which the reinforcement mesh comprises a surface area which is smaller than the area of the surface of the heat insulating board.

  • Publication number: 20130199245
    Abstract: 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.

  • Publication number: 20130186149
    Abstract: 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.
