Abstract: A combustion burner refractory material retention system is provided. The system may include a tubular enclosure having a first section and a second section, wherein the first section has an internal cross-sectional area that is less than an internal cross-sectional area of the second section. A refractory material body may be disposed within the tubular enclosure second section. A first support layer may be disposed on a surface of the refractory material body, and at least one outer support layer may be disposed between the refractory material body and a wall of the tubular enclosure second section. The first support layer may form an insulating barrier between the refractory material body and the outer support layer, and a cross-sectional area of the combined refractory material body and first support layer may be at least as large as the internal cross-sectional area of the tubular enclosure first section.

Abstract: An exhaust treatment device is provided for a power system. The exhaust treatment device has an inlet module, a filter module, an outlet module, and a clamping element. The filter has a housing with at least one submerged flange. At least one of the inlet and the outlet modules also have at least one submerged flange. The clamping element is configured to engage the at least one submerged flange of the filter module and the at least one submerged flange of the at least one of the inlet and the outlet modules to connect the filter module to the at least one of the inlet and outlet modules.

Abstract: A filter element has a filter media and at least one base member. The filter element further has a ceramic paste connecting the filter media to the at least one base member.

Abstract: A particulate trap has a housing with an inlet and an outlet. The particulate trap also has a plurality of fluidly isolated filters stacked within the housing, between the inlet and the outlet. The stacked plurality of filters have a stack direction and a transverse direction and the flow of exhaust is directed through the plurality of filters in the transverse direction. The particulate trap further has an actuator with a blocking portion configured for linear movement to selectively block exhaust flow through each of the plurality of filters.
