Abstract: A heating assembly can include a switching valve which can include certain pressure sensitive features. These features can be configured to change from a first position to a second position based on a pressure of a fuel. The valve can be used with either a first fuel or a second fuel different from the first. The valve can become locked or be held in either the first or the second position. For example, a set fuel pressure can cause the valve to move to a closed position and the valve can become locked or held in that position. If the pressure decreases, the valve can remain in the locked position. Actuation of a reset switch can allow the valve to move to a new position, such as an open position.

Abstract: The effects of different perovskite catalysts, catalytic active materials with a crystal structure of ABO3, on matrix stabilized combustion in a porous ceramic media are explored. Highly porous silicon carbide ceramics are used as a porous media for a catalytically enhanced matrix stabilized combustion of a lean mixture of methane and air. A stainless steel combustion chamber was designed incorporating a window for direct observation of the flame within the porous media. Perovskite catalytic enhancement of SiC porous matrix with La0.75Sr0.25Fe0.6Cr0.35Ru0.05O3; La0.75Sr0.25Fe0.6Cr0.4O3; La0.75Sr0.25Fe0.95Ru0.05O3; La0.75Sr0.25Cr0.95Ru0.05O3; and LaFe0.95Ru0.05O3, for example, were used to enhance combustion. The flammability limits of the combustion of methane and air were explored using both inert and catalytically enhanced surfaces of the porous ceramic media. By coating the SiC porous media with perovskite catalysts it was possible to lower the minimum stable equivalence ratio.
