  • Patent number: 11220643
    Abstract: Disclosed is a hydrogen generation furnace using decomposition of biomass steam, which employs an infrared source and a furnace body with a water-accommodating structure. A steam separation-drying device is cylindrical and provided at an upper part of an interior of the furnace body and a cavity of the steam separation-drying device forms a secondary gasifier. A lattice plate is provided at a bottom of the interior of the furnace body. A lattice combustion grate is provided above a middle of the lattice plate. A steam distributor is provided outside a lower part of the furnace body. The furnace of the invention performs gasified gas separation as well as secondary oxidation and gasification and mixes steam with gas generated from biomass to perform a decomposition reaction for generating hydrogen.

  • Patent number: 11130922
    Abstract: The invention provides a hydrogen boiler based on coal gasification and water decomposition, including a steam boiler which includes an upper furnace and a lower furnace; water and steam in the upper furnace are respectively communicated with water and steam in the lower furnace; and the steam boiler is provided with a casing which has a narrow gap for containing water and a wide wall for heating to generate gas. The steam boiler contains multistage reactors. A coal modification and gasification device is provided at an outer side of the steam boiler and is provided with two chambers. The steam and gasified gas of coal are mixed and enter the reactors for direct burning to promote respective reactions. After several stages of modification and decomposition, the steam and the gasified gas of coal are completely converted to hydrogen.

  • Patent number: 10203107
    Abstract: In a clean boiler with steam conversion and hydrogen/oxygen pre-blending, the clean boiler comprises two identical boiler bodies integrated to form a single entity. The clean boiler comprises two slim cavities, four water-containing chambers and four combustors, which is heated at wide faces and generates steams rapidly. The boiler comprises an integrate body containing two independent boiler bodies (1), and each of the independent boiler bodies (1) contains an independent boiler chamber (19). A steam conversion and transformation system is simultaneously provided for introducing a part of steam into the independent boiler chamber (19). High temperature of the boiler chamber (19) is utilized to promote a decomposition of the steam into H2 and O2. Water formed by H2 and O2 is utilized as a fuel to provide a self-sustaining combustion and heating, thus reducing a dependence on a primary energy source, reducing carbon emissions and protecting the environment.

  • Patent number: 10190764
    Abstract: The present invention provides an infrared hydrogen/oxygen combustor. The structure of the combustor includes a sinus ring (1). A surrounding foot (12) of the angle-shaped sinus ring (1) wraps a material-containing basin (14). A first small tube (16) and a second small tube (7) are connected the material-containing basin (14) and the angle-shaped sinus ring (1). Water solution (3) is contained in the material-containing basin (14). A straight-hole ceramic water-absorbing board (5) is provided on the upper part of the water solution (3), a spacing ring (6) is provided above the side of the material-containing basin (14) and in the upward ring of the angle-shaped sinus ring (1), a two-stage material-containing box (9) with a separated brake is provide on one side of the angle-shaped sinus ring (1). The technical scheme of the invention reduces the production cost, the pollution and protects the environment.
