摘要： PURPOSE:Small equipment which circulates circulating water from a steam separating drum through a feed water tank, deoxidises the feed water, and reduces the temperature of the circulating water. CONSTITUTION:Heating pipe 14 is placed in a feed water tank 1 and the feed water is heat exchanged by passing through the pipe the hot circulating water from the steam separating drum, and at the same time, the feed water in the feed water tank is deoxidised by heating, and the deoxidised water is directly mixed with the circulating water. Thus the equipment itself can be made smaller and the corrosion by air is prevented from the pipe 8.

摘要： PURPOSE:To protect reheater from deformation burning, separating reheater of regeating boiler into the primary reheater and the secondary reheater, arranging the secondary reheater pipe on high temperature side vertically, installing on the downstream of superheater. CONSTITUTION:This reheating boiler is constructed arranging superheater 3 in the combustion chamber 2, installing vertical the secondary reheater 4 to lower portion of steam drum 1 in the downstream of superheater 3, additionally installing the primary reheater 5 made of horizontal flexible pipe 25 in the smoke tube 28 in the downstream of combustion chamber 2. The secondary reheater 4 pipe will diform hardly through above construction, gas temperature passed through the smoke path 28 can be maintained sufficiently lower without many generating tube like usual boiler, since gas temperature flowed into the primary reheater 5 constructed with horizontal tubes can be lowered, care due to deformation and burning supporting meterial can be solved.
