A catalytic burner arrangement is provided including at least a catalytic burner unit with a housing having a reaction chamber in which a catalyst is arranged, wherein the catalyst is adapted to react a fuel, particularly a hydrogen containing fluid, with an oxidant, particularly air, for producing heat, the housing having a fluid inlet for supplying a fluid stream into the housing and a find outlet for exiting a fluid stream from the housing, and the catalytic burner arrangement further includes a mixing unit forming a mixing chamber in which fuel and oxidant are mixed, wherein the mixing device includes a fuel inlet, an oxidant inlet and an fuel-oxidant-mixture outlet, and wherein the fluid inlet of the catalytic burner unit merges with the fuel-oxidant-outlet of the mixing unit for transferring the fuel-oxidant-mixture from the mixing chamber to the reaction chamber of the catalytic burner unit wherein the fuel-oxidant-outlet of the mixing chamber is pipe-shaped and extents into the mixing chamber of the mixing unit, and wherein a length of the pipe-shaped fuel-oxidant-outlet extents over the oxidant inlet and/or the fuel inlet.

A gas-fueled portable device for the thermal dispensing of volatile materials such as insect repellents is described. The device employs a pressure regulator to establish gas flow, heat generation, and dispensing temperature at pre-determined optimal values. The automatic operation at pre-determined settings provides simple on/off operation for the user of the device.

This invention describes a new porous hydrogen burner that is intended to be installed on different types of furnaces requiring a precise monitoring of the thermal flux, and in particular furnaces for steam-reforming of natural gas or naphtha.

A steam generating system includes a furnace, a nozzle tip assembly for pulverized coal and primary air as well as means for conveying secondary air in the furnace. The nozzle according to the invention comprises a nozzle body (3) and several channels (5) being connected with the nozzle body, the channels are diverging from each other. At the exit faces (17) of the channels obstructions (13) are disposed to induce huge turbulences of the primary air when entering the furnace. Due to these turbulences the primary air and the entrained coal are mixed very well before being combusted in the furnace. This results in a better more effective combustion with reduced NOx-emissions.

Systems, methods and apparatus for the thermal conversion of biomass into biochar. A mobile platform may be used to maneuver a mobile biochar generation system within a field of biomass. The biomass may be harvested, preprocessed and pyrolyzed. After pyrolyzation, the biochar may be cooled to a predetermined temperature by integrating water and liquid nutrients into the biochar. The system may then control the application of the infused biochar by adjusting a spreading attachment and a plowing attachment.

A gas treatment system includes a first scrubber, a regenerative catalytic oxidizer (RCO) that treats gas that passes through the first scrubber, a second scrubber that treats the gas that passed through the regenerative catalytic oxidizer, and a dielectric barrier discharge (DBD) plasma reactor that treats the gas that passed through the second scrubber. The regenerative catalytic oxidizer includes a two-bed regenerative catalytic reactor.
