Abstract: A high temperature industrial roof assembly having two refractory bricks with adjacent faces, opposing hanger recesses, a hanger rod extending from the recesses to the top of the assembly, the refractory bricks being held in an adjacent position by a securing device, a hanger rod with a locking mechanism at one end and a hook at the other end, a hanger having opposed refractory engaging projections adapted to engage the hanger recesses, a hanger rod hole allowing free rotation about the hanger rod end above the locking mechanism, and a locking mechanism engagement recess which when engaged with the locking mechanism prevents rotation of the hanger rod in relation to the hanger at 90 degree increments and provides that depression of the one end of the hanger rod into the locking mechanism engagement recess permits rotation of the hanger rod with respect to the hanger. The locking mechanism comprises opposing tabs.

Abstract: A modular solids charger for feeding granular solid material to a reactor, the charger comprising a chassis, a charger plate support frame vertically and angularly adjustable with respect to the horizontal secured to the chassis, a removable reciprocable charger plate reciprocably secured to the charger plate support frame, a removable solids supply chute disposed above the reciprocable charger plate for feeding solids to the reciprocable charger plate, spacers for adjusting the elevation of the chassis to accommodate a range of elevations of reactor feed openings, and charger plate support frame extensions to enable the charge plate support frame to accommodate a range of reciprocable charger plate widths.

Abstract: A refractory brick for high temperature industrial furnace roof construction which accommodates hanger attachment at a plurality of locations along the length of the hanger brick. A high temperature industrial roof system having alternate rows of hanger bricks, of the above configuration, and filler bricks which are at least 2 1/2 times as wide as the hanger bricks and can be individually removed by lifting from the top of the furnace. The high temperature industrial furnace roof may be constructed of two configurations of refractories with shortening of the length of either configuration of refractory to accommodate designs having a wide variety of roof widths. Electrically heated furnaces have bus bars which run along the length of the furnace and are fed through the top of the furnace.

Abstract: A solids charger of the type having a main support frame with a solids supply chute thereabove feeding solids to a vertically and angularly adjustable, with respect to the horizontal, reciprocable charger plate positioned under the solids supply chute for receiving solids toward its rear end and feeding the granular solid materials to a reactor from its front end. The improvement in such a solids charger of a reciprocable charger plate reciprocably mounted in fixed angular relation to a charger plate support, reciprocating drive means fixedly mounted to the charger plate support and connected by an adjustable connecting rod with the rear end of the reciprocable charger plate, the connecting rod reciprocating generally parallel to the plane of the charger plate.

Abstract: A high temperature furnace curved nose construction having refractories suspended from a support structure wherein a combination of radial filler refractories and rectangular filler refractories are supported by rectangular hanger refractories. Each radial filler refractory is supported by radially adjacent rectangular filler and/or rectangular hanger refractories. Each radial filler refractory has opposed converging tread sides while each rectangular filler refractory and rectangular hanger refractory have four tread sides. The tread sides of a radial filler refractory mates with the tread sides of a rectangular filler refractory or a rectangular hanger refractory. Any combination of at least one rectangular hanger refractory, at least one rectangular filler refractory and at least one radial filler refractories mate by their tread sides to form at least a section of the curved nose construction.

Abstract: A refractory brick panel module and suspended roof construction for high temperature furnaces wherein the panel module has a refractory support frame of at least two substantially parallel support members with at least one end of the support members having extension and retraction means forming an extendable and retractable refractory support frame end portion. The refractory support frame end portion in retracted position allows passage of the refractory support frame between adjacent roof support beams and in extended position provides refractory brick suspension beneath the roof support beams to a proximity to adjacent roof panel modules. The extendable and retractable refractory support frame allows great flexibility in modular suspended roof construction, providing easy repair of either entire modules or replacement of a relatively small number of refractory bricks from the cold side of the furnace roof.

Abstract: A suspended roof construction for industrial furnaces is disclosed having carrier bricks of generally rectangular configuration with a hanger recess in one side and shoulder means extending from the upper portion of sides adjacent the hanger recess for support of filler bricks. Thus, a single hanger suspends two carrier bricks which in turn support four filler bricks. Such assemblies of bricks may be fabricated into panel units which provide telescoping tubes on at least one end of hanger tubes for suspension of end bricks between adjacent panel modules. The telescoping tubes may be retracted, the panel unit lowered into place between the structural frame of the furnace roof, the telescoping tubes extended and filler bricks hung from cross bars at each end of the panel unit to fill the spaces between adjacent panels.

Abstract: A high temperature industrial furnace roof assembly wherein two refractory bricks are held in adjacent position by suitable securement and have a hanger rod extending from the assembly to suspend the roof assembly from a support structure in desired position in a furnace roof. The hanger rod is maintained in locked position when the weight of the roof assembly is placed upon it. The hanger rod may be depressed into the refractory bricks permitting free rotation of the hanger rod with respect to the hanger and brick assembly and locked into desired position at 90.degree. increments by a force applied to the hanger rod in a direction away from the brick assembly. The roof assembly of this invention is particularly desirable for furnace roof repair and provides for easy installation in operating high temperature furnaces permitting the long axes of the repair assembly to be changed on the jobsite by rotation of the hanger.

Abstract: A high temperature refractory structure having refractory brick lining including a support frame, a plurality of spaced hanger beams inwardly from the support frame and having opposed flanges, a plurality of spaced hanger beam clips engaging one of the hanger beam flanges for attachment to a support frame, a plurality of refractory hangers engaging the other of the hanger beam flanges, and a plurality of refractory bricks supported by the refractory hangers, the refractory hangers engaging hanger flanges of refractory bricks thereby supporting the refractory brick lining, the refractory brick hanger flanges being at approximately right angles to the hanger beam flanges. Also disclosed is a sheet metal beam clip of substantially U-shape for fastening one beam at right angles to another.
