Apparatus and method for simulation of combustion effects in a fireplace
InactiveUS20050097792A1Transparent highAvoid flowDomestic stoves or rangesLighting and heating apparatusFiberEmber
The present invention produces a combustion simulation of flames, burning logs and embers in a fuel-burning fireplace or like device. One or more light source(s), such as LEDs, are used to transmit light to and through: a flame cut-out panel or flame cut-out mask to simulate the flame effect; cut-outs in logs to simulate a burning edge of a log; elements or refractories that refract the light to simulate real burning embers. Fiber optic cables, or any other material that facilitates the transmission of light, may be used to assist in transmitting the visible light. A motor driven rotating disk that includes apertures may be used to fragment the transmission of the visible light. In addition, the light source may be controlled by a sequencing device to closely approximate the pulsing intensities of light seen in actual flames, the edges of burning logs, and ember beds.

There is described an apparatus for making metal oxide particles which are substantially free of coarse tail from an oxidizing agent and a metal reactant in a flow reactor. The apparatus can be a concentric tubular flow reactor comprising a substantially funnel-shaped reactant contacting region located adjacent to a reaction zone which is able to direct a flow of a hot oxidizing agent towards a flow of the metal reactant to form a reaction stream which flows downstream into a reaction zone, whereby the hot oxidizing agent of the reaction stream is able to surround the flow of metal reactant sufficient to prevent the metal reactant from contacting the wall of the reactant contacting region and forming scale on the wall. A cooling fluid conduit being able to direct a flow of a cooling fluid into the reaction zone to flow coaxially with the reaction stream and to form a fluid curtain between the reaction stream and a baffle, which defines at least a portion of the reaction zone, while the metal reactant and hot oxidizing agent within the reaction stream react to form the metal oxide nanopowder prevents scale from forming on the baffle.
