Abstract
A catalytic section of a combustor is formed from a spaced tandem array of corrugated panels. The exterior top and bottom surfaces of the panels are coated with a catalyst and the space between panels defines a passage for a fuel-rich/air mixture. The interior of the corrugated panels define cooling air passages for maintaining the catalyst and substrate on which it is formed, at acceptable temperatures.
Claims27
A combustion turbine combustor having an elongated catalytic section comprising a tandem arrangement of passages defined in part by first and second side walls, with each of said side walls having a plurality of grooves extending in the direction of the elongated dimension of the catalytic section, alternate passages in said tandem arrangement comprising a top plate and a bottom plate attached to and affixed together by an undulating member alternately forming ridges and grooves that respectively attach to the top and bottom plates to form a corrugated member, the undulating member extending substantially from a first laterally extending side to a second laterally extending side of the top and bottom plates relative to the elongated dimension, each of said corrugated members being supported on the first laterally extending side within at least one of the grooves in the first side wall and on the second laterally extending side within at least one of the grooves in the second side wall.
A combustion turbine having a combustor including an elongated catalytic section comprising a tandem arrangement of passages defined in part by first and second side walls, with each of said side walls having a plurality of grooves extending in the direction of the elongated dimension of the catalytic section, alternate passages in said tandem arrangement comprising a top plate and a bottom plate attached to and affixed together by an undulating member alternately forming ridges and grooves that respectively attach to the top and bottom plates to form a corrugated member, the undulating member extending substantially from a first laterally extending side to a second laterally extending side of the top and bottom plates relative to the elongated dimension, each of said corrugated members being supported on the first laterally extending side within at least one of the grooves in the first side wall and on the second laterally extending side within at least one of the grooves in the second side wall.
A chemical catalytic reactor including an elongated catalytic section comprising a tandem arrangement of passages defined in part by first and second side walls, with each of said side walls having a plurality of grooves extending in the direction of the elongated dimension of the catalytic section, alternate passages in said tandem arrangement comprising a top plate and a bottom plate attached to and affixed together by an undulating member alternately forming ridges and grooves that respectively attach to the top and bottom plates to form a corrugated member, the undulating member extending substantially from a first laterally extending side to a second laterally extending side of the top and bottom plates relative to the elongated dimension, each of said corrugated members being supported on the first laterally extending side within at least one of the grooves in the first side wall and on the second laterally extending side within at least one of the grooves in the second side wall.
