  • Patent number: 11821194
    Abstract: An arch building structure includes a plurality of structural arch assemblies, a plurality of purlins, and a plurality of flat roofing sections. The plurality of structural arch assemblies is positioned parallel and offset from each other upon the length of the building. The plurality of purlins is positioned perpendicular to the plurality of structural arch assemblies and radially positioned on the vertexes of the plurality of structural arch assemblies to further strengthen the building. Each of the plurality of flat roofing sections is mounted across a corresponding pair of adjacent purlins from the plurality of purlins so that the building roof can be completed.

  • Patent number: 10125972
    Abstract: An evaporation cycle of a natural circulation steam generator. An evaporator is in flow connection with a downcomer pipe and includes a first evaporative section and a second evaporative section connected in parallel with the first evaporative section and arranged at a higher level than the first evaporative section. The evaporator cycle is not associated with another external source of motive force than heat from the gas flow to assist the flow of the water in the evaporator, and the evaporator has a vertically extending outlet collector for collecting the steam and water from the first and second evaporative sections to the riser pipe. The outlet collector includes a lower portion and an upper portion above the lower portion. The first evaporative section is in direct flow connection with the lower portion and the second evaporative section is in direct flow connection with the upper portion.

  • Patent number: 9975088
    Abstract: The present invention relates to a method for purifying a gas comprising: a) feeding the gas (1) to an absorber (5) and bringing into contact said gas (1) with a stream (3) (or alternatively (3?)) to obtain a liquid (4) and a purified gas stream (2); b) feeding the liquid (4) to a conditioning tank (9) and adding a mineral nutrient medium (6) and a suitable amount of base (7) to the liquid (4) to obtain a liquid effluent (8); c) feeding the liquid effluent (8) to an anaerobic bioreactor (14) to obtain a biomethane stream (11) and a liquid stream (12); d) feeding the liquid stream (12) to a degasser (20) to obtain a gas stream (18) and a stream (3?); and e) recirculating the stream (3?) by feeding it to the absorber (5).

  • Publication number: 20120129112
    Abstract: A method of and a system for combusting fuel in an oxyfuel combustion boiler. Fuel is fed to a furnace of the boiler. Oxidant gas that includes a mixture of substantially pure oxygen and recycled flue gas is fed to the furnace, prior to the feeding of the oxidant gas. At least a portion of the oxidant gas is preheated to generate preheated oxidant gas. The fuel is combusted with the oxidant gas in the furnace so as to generate steam and to produce the flue gas, and at least a portion of the steam is superheated to generate superheated steam. The preheating of the at least a portion of the oxidant gas is performed by using a heat exchanger that transfers heat from a portion of the superheated steam to the oxidant gas.
