Abstract:
A boiler for cooling waste gases has side walls including a pair of opposite side walls defining a passage through which the waste gases flow, cooling-tube sections in the passage against the walls, and at least one tubular tie rod having outer ends anchored in the opposite side walls and extending transversely through the passage, A coolant is pumped through the cooling-tube sections and through the tubular tie rod. The tie rod extends straight through the passage and is braced at its ends under tension against the opposite side walls.
Abstract:
A deformable and replaceable energy absorbing structure mounted between the furnace floor tubes and floor tube support truss to absorb impact from falling slag and prevent tube damage. A beam, such as an I-beam extends from the supporting structure and is adapted to hold a deformable structure. A tie bar attached to the floor tube panel extends across the panel and rests upon the deformable structure. This arrangement is provided at as many contact points between the floor tube panel and support structure as necessary to support the dead weight of the tubes while still providing suitable energy absorption characteristics.
Abstract:
A VAPOR GENERATING AND SUPERHEATING UNIT HAVING ITS COMPONENTS ARRANGED TO SUPPORT IT IN BOTH HORIZONTAL AND VERTICAL POSITION AND INCLUDING A PLURALITY OF HEADERS DISPOSED ADJACENT ONE OF THE SIDEWALLS, SAID SIDEWALL BEING LOWERMOST WHEN THE UNIT IS IN HORIZONTAL POSITION.
