  • Publication number: 20220010472
    Abstract: The invention relates to a method and facility for manufacturing a cross-linked fiberglass material, in which melted glass is produced in a melting furnace heated via combustion of a fuel with an oxygen-rich oxidant. The melted glass is converted into glass filaments, the filaments are bonded, a sheet is made from the bonded filaments, and the sheet is then cross-linked. The fumes from the melting furnace are used to preheat a combustion reagent in two steps: a first step in which air is heated via heat exchange with the fumes, and a second step in which the combustion reagent is preheated via heat exchange with the hot air. The air is then used in the cross-linking step of the method for converting the melted glass into a fiberglass material.

  • Patent number: 10715313
    Abstract: A method is implemented in a networked computer system that is connected to document issuers and validators and interacts with a blockchain. It comprises generating a master key assigned to an issuer, certifying a document through a first process including generating a document persistence key, encrypting document data with an encryption algorithm and an encryption key derived from three keys (the master key, the document persistence key and an intermediate key), registering encrypted document data in the blockchain, and generating a web address carrying recovery information of the certified document; reading the document through a second process accessible to the web address, the second process including recovering the encrypted data in the blockchain and accessing the three keys, decrypting the encrypted data using the encryption key derived from the three keys, and displaying the document; and upon request from a legitimate holder of the document erasing the persistence key.

  • Publication number: 20190331423
    Abstract: Furnace operation includes consecutive cycles of a heating step, a stopping step and a restarting step. The fuel and/or the oxidizing agent is preheated upstream of the furnace by indirect exchange with the discharged fumes through a medium passing through a chamber. A first wall separates the fumes from the medium in the chamber. The fuel and/or oxidizing agent is separated from the medium in the chamber by second wall. During restarting, the medium's flow rate Dm is regulated to limit the heating rate of the first wall until it reaches the operational temperature at an end thereof.

  • Patent number: 8632621
    Abstract: A simple, compact burner achieves a more optimal melting of a solid charge followed by performance of combustion under distributed combustion conditions. The burner achieves this by fluidically bending the flame towards the solid charge during a melting phase with an actuating jet of oxidant, redirecting the flame in a direction away from the charge, and staging injection of oxidant among primary and secondary portions during a distributed combustion phase.
