International Classification:

B05B 1708

US Classification:

239 17

Abstract:

Water display nozzle shields for allowing water display nozzles to be positioned and operated below the surface of the body of water without constant entrainment of water from the body of water affecting the nozzle characteristics. In one embodiment, a rotatable shield assembly is controllably rotatable between first and second positions. In the first position, the shield assembly is positioned over the nozzle of the water display and substantially sealed with respect thereto, the shield extending from adjacent the exit end of the nozzle which is positioned below the water level, to a position above the water level. When rotated to a second position, the nozzle shield, as well as the nozzle, are both disposed below the surface of the water so as to not be visible. In another embodiment, a weighted inflatable member is attached to the nozzle adjacent the exit thereof which, when inflated, will float to the surface of the water to provide a shield functioning as here before described and which, when deflated, will sink below the surface of the water out of sight. Various features of the shields are disclosed.

Abstract:

Methods and devices for combusting a carbonaceous fuel in an oxy-combustion fluidized bed reactor involving controlling the local oxygen content within the oxy-combustion reactor to specified levels. The carbonaceous fuel and an oxygen-containing gas are introduced into a fluidized bed reactor and eluted through a fluidized bed of an inert material, dolomite or a combination thereof to combust the fuel and oxygen to produce at least COand steam. The oxygen-containing gas is a mixture of oxygen, recycled COand steam and has sufficient oxygen added to the recycled COand steam that the mixture contains 7-20 mole % oxygen. The carbonaceous fuel and the oxygen-containing gas are introduced into the fluidized bed at a location in sufficiently close proximity to each other to avoid producing a reducing atmosphere at the location. At least a portion of the produced COand steam are recycled to the reactor.

Abstract:

Methods, devices and systems for processing of solid materials, particularly fuel material solids such as carbonaceous fuel solids such as of granular form, to provide or result in an even distribution of the solid material. Hoppers are provided with plurality of outlet orifices, each of the outlet orifices adapted to flow therethrough a combination of gas and the solid material to pneumatically convey the solid material to a distribution manifold. The distribution manifold includes a plurality of tubes with each tube having a plurality of exit orifices wherein each exit orifice passes an equal portion of the combination of the gas and the solid material.
