  • Publication number: 20210140175
    Abstract: The invention involves using composite panels to a framework to create a standard reusable rapidly deployable building structure, even in remote areas under favourable weather conditions. The invention discloses a minimal set of components, assemblies and methods where logistics are simplified through the use of flat-pack shipping and minimal use of field fasteners/tools. No crane or specialized trades are required to construct the building on site Standardization allows for interchangeability of components for repair or changing of building dimensions either during the initial construction or later. Most components are commercially available materials joined into assemblies using simplified manufacturing operations to reduce costs. Most assemblies, including flanges and cleats connecting adjacent composite panels, rectangular and/or triangular lattice (truss), transom, pier, columns, shear pins with retention means, are re-usable should the building require repairs, re-purposing or relocation.

  • Patent number: 8505496
    Abstract: A method of introducing oxygen into a boiler system for combustion with a prepared fuel in a furnace combustion chamber comprises providing a plurality of swirl-inducing elements to the air stream delivery lines, and a plurality of oxygen delivery jets adjacent the intake region and substantially surrounding the air stream delivery lines; igniting the fuel gas to create a flame; and delivering a stream of oxygen through the jets tangentially to the flame envelope to substantially shape and stabilize a swirling flow field for the flame, the oxygen concentration in the flame envelope gradually increasing towards an outer periphery of the flame envelope. A boiler system for using the method can be a new system or a retrofit to an existing system. The method and system provide advantages in reduced environmental impact and increased efficiency while addressing the safety factors involved in introducing oxygen to boiler systems.
