Claim Text:
1. A suspended combustion type power steam generator, comprising: a continuous inlet disposed on a top of a combustion chamber to continuously supply fine refuse derived fuel (FRDF); a continuous outlet disposed on a bottom of the combustion chamber to discharge combustion material; a hollow dry distillation high pyrolysis down combustion type water tube boiler having a firebox first water pipe connecting a water drum and a steam drum; a down pipe connected to a header circulator directly connected to the water drum, and downwardly inclined to be connected to a header; an arch header pipe directly connected to an arch header connecting an arch pipe and a heating pipe extended respectively from the header and installed in opposite to each other, and extending upwardly; a front water wall header circulator connected to a first end of a horizontal left and right pipe wall header connected to a left and right pipe wall header circulator directly connected to the water drum, and extending upwardly; a front water evaporation rise pipe upwardly extended from a front wall header connected to the arch header pipe and the front water wall header circulator, and connected to the steam drum of a water tube boiler; a number of refractory arch tubes upwardly obliquely extended from the arch header through a center of the combustion chamber, and smoothly bending closer toward the steam drum to be connected to the steam drum; a heat-storage refractory arch on an upper side of the refractory arch tubes at the center of the combustion chamber to further maximize the endothermic reaction effect; and a baffle plate portion disposed in the combustion chamber under the refractory arch to prolong a residence time of high temperature gas generated by the combustion of FRDF and to promote a heating condition of a fluid in the arch pipe, the heating pipe, and the down pipe, wherein the baffle plate portion comprises at least two or more first baffle plates extending downwardly from an upper portion of a pyro combust disposed in an upper portion of the combustion chamber, and at least two or more second baffle plates extending upwardly from a lower portion of the combustion chamber, and wherein the first baffle plates and the second baffle plates are disposed alternately with each other such that a lower end portion of each of the first baffle plates and an upper end portion of each of the second baffle plates are overlapped with each other.
