Abstract
Refractory bricks, suspended wall of refractory bricks, and a method for mounting refractory bricks for protection of membrane boiler tube walls. The pre-fired brick has a rectangular generally flat exterior face, a top face having an upper groove extending across the top face generally parallel to the exterior face, a bottom face having a lower groove extending across the bottom face generally parallel to the exterior face, the upper groove being deeper than the lower groove, the upper and lower grooves sized and spaced to accommodate mounting bars attached to the membrane boiler tube wall.
Claims13
A pre-fired brick for protecting membrane boiler tube walls comprising:
- an elongated brick having a rectangular generally flat exterior face, a top face having an upper groove extending across said top face generally parallel to said exterior face, a bottom face having a lower groove extending across said bottom face generally parallel to said exterior face, said upper groove being deeper than said lower groove, said upper and lower grooves being sized and spaced to accommodate mounting bars attached to said membrane boiler tube walls.
A suspended pre-fired brick wall for protecting a membrane boiler tube wall comprising:
- a plurality of spaced mounting bars attached generally horizontally to the exterior of said membrane boiler tube wall;
- plurality of pre-fired bricks locked into side-by-side position on adjacent said mounting bars substantially filling the space between said adjacent mounting bars and forming a row of said bricks, each said brick being an elongated brick having a rectangular generally flat exterior face, a top face having an upper groove extending across said top face generally parallel to said exterior face, said upper groove being deeper than said lower groove, said upper and lower grooves being sized and spaced to accommodate said mounting bars, said upper groove engaging the upper said adjacent mounting bar and said lower groove engaging the lower said adjacent mounting bar thereby locking each said brick into position.
A method of installing pre-fired brick for protection of membrane boiler tube walls, said method comprising:
- positioning the upper portion of an elongated brick having a rectangular generally flat exterior face, a top face having an upper groove extending across said top face generally parallel to said exterior face, a bottom face having a lower groove extending across said bottom face generally parallel to said exterior face, said upper groove being deeper than said lower groove, said upper and lower grooves being sized and spaced to accommodate mounting bars attached to said membrane boiler tube walls, in position so that an upper said mounting bar enters said upper groove;
- sliding said brick upwardly until said bottom face clears the top of an adjacent lower said mounting bar;
- positioning the lower portion of said brick aligning said lower groove with said lower mounting bar;
- moving said brick downwardly to lock it into position on both said upper and lower mounting bars.
