A protective wall structure for protecting boiler tubing in facilities using refuse as a fuel source to produce steam for electrical power generation. The protective wall structure includes an array of shielding tiles, heat transfer bonding material, and elongated compressible material. The shielding tiles include a front surface facing the interior combustion zone of the facility, a rear surface facing the boiler tubes, and a plurality of sidewall surfaces. The heat transfer bonding material is positioned between the boiler tubes and the rear surfaces of the shielding tiles to permit heat transfer and create a bond between the boiler tubes and the shielding tiles. The elongated compressible material is positioned between the sidewall perimeter surfaces of adjacent shielding tiles to provide an expansion joint. This permits relative expansion between adjacent shielding tiles without cracking upon an increase in temperature in the interior combustion zone.

A new carriage system for a ram feeder has been designed and is provided. As in the prior art, the carriage system has a drive cart to which is attached a driving force member at one end thereof and a ram member on the other and opposing end thereof. The drive cart is supported by and travels upon a carriage table. The carriage system of the present invention replaces the prior art wheel and flat rail arrangement under the drive cart. The wheels together with the associated problems have been eliminated. In the present invention, the carriage system has a guide member attached to the carriage table and a travel member attached to the underside of the drive cart. The guide member is longitudinally oriented on the carriage table in the direction of drive cart travel and has at least one upper wear portion. The guide member guides the drive cart and the attached ram member during a reciprocating stoke cycle of the driving force member. The travel member has at least one lower wear portion.
