A downhole torch system and method of use includes a cylindrical housing, a protective material provided on at least one of the cylindrical housing and the fuel load, and a fuel load located within the cylindrical housing. The protective material is provided between the fuel load and the cylindrical housing to protect the cylindrical housing from adverse effects caused by the reaction of the burning fuel and/or the subsequent production of combustion products for cutting and/or perforating processes during operation of the torch system. The protective material significantly improves the cutting and/or perforating performance of the torch system.

Combustor assemblies are provided. An exemplary combustor assembly comprises an annular ceramic matrix composite (CMC) inner liner including an inner liner flange, an annular CMC outer liner including an outer liner flange, and an annular CMC combustor dome comprising a plurality of tiles positioned circumferentially adjacent one another. Each tile has a first end radially opposite a second end. The CMC inner liner, outer liner, and combustor dome form a combustor, and the CMC combustor dome is positioned at a combustor forward end. The combustor assembly also comprises a support structure for supporting the combustor and including an annular frame having a frame channel defining a groove and an inner and outer support flanges. The first end of each tile is disposed within the frame channel groove. The inner liner flange is secured to the inner support flange and the outer liner flange is secured to the outer support flange.

Provided is a duct wall surface structure which, in a flue of an iron-sheet duct with a hopper through which a solid-gas two-phase stream flows, can enhance the solid particle trapping efficiency of the hopper and reduce the outflow of the solid particles to the duct downstream side. The duct wall surface structure of a flue (10) through which a solid-gas two-phase stream containing large-diameter ash (50) flows includes a first hopper (20A) installed at the lower end of a first vertical flue section (12), installed in such a direction that the stream has a vertical component of velocity, to collect the large-diameter ash (50) from the stream, wherein a low-rebound part (60) having a lower coefficient of restitution than an iron sheet is provided on an inclined surface (21), with which the large-diameter ash (50) collides, on the upstream side in the flow direction from the first hopper (20A).
