Suspended combustion type power steam generator capable of rapid and high-temperature pyrolysis using frdf for extending residence time of high-temperature gas

A suspended combustion type power steam generator capable of rapid and high-temperature pyrolysis using FRDF for extending residence time of high-temperature gas, including a hollow dry distillation high pyrolysis down combustion type water tube boiler having a continuous inlet 11 on the top of a combustion chamber to continuously supply fine refuse derived fuel (FRDF) thereinto, and a continuous outlet 14 on the bottom of the combustion chamber to discharge combustion material, and a firebox first water pipe 70 of a four pass connecting a water drum 8 and a steam drum 7,

• the suspended combustion type power steam generator further comprising:
• a down pipe 9 connected to a header circulator 91 directly connected to the right and left outer side of the water drum 8, and downwardly inclined to be connected to a header 1;
• an arch header pipe 32 directly connected to an arch header 3 connecting an arch pipe 2 and a heating pipe 4 extended respectively from the upper side and the lower side of the header 1 and installed in opposite to each other, and extending upwardly;
• a front water wall header circulator 62 connected to the one end of a horizontal left and right pipe wall header 10 connected to a left and right pipe wall header circulator 101 directly connected to the left and right inner side of the water drum 8, and extending upwardly;
• a front water evaporation rise pipe 6 upwardly extended from a front wall header 61 connected to the arch header pipe 32 and the front water wall header circulator 62, and connected to the steam drum 7 of a water tube boiler 22 installed at the read side;
• a number of refractory arch tubes 31 upwardly obliquely extended from the arch header 3 through the center of the combustion chamber, and smoothly bending closer toward the steam drum 7 to be connected to the steam drum 7;
• a heat-storage refractory arch 33 on the upper side of the refractory arch tubes 31 at the center of the combustion chamber to further maximize the endothermic reaction effect;
• and
• a baffle plate portion 50 in the combustion chamber under the refractory arch 33 to prolong the residence time of high temperature gas generated by the combustion of FRDF inside the combustion chamber and to promote fluid heating condition in the arch pipe 2, a heating pipe 4, and the down pipe 9.
