To provide an integral divided-flow water coil-type air heater and economizer (IWE) capable of significantly lowering a final outlet gas temperature in comparison with a temperature economically available by using the newest technology.
The total inflow amount of supplied water is divided into a first flow part 22 of high temperature and low-mass, and a second flow part 24 of high temperature and high-mass in comparison with the first flow part, by a dividing means. The first flow part 22 is distributed through a heat transfer loop including an essential part of a heat transfer face of a WCAH (water coil type air heater) 12 and increase LMTD (logarithmic mean temperature difference) between the water and an economizer gas. The second flow part 24 has a minimum heat transfer face, and moves along a conducting pipe for moving most of the water. As the first and second flow parts 22, 24 respectively generate heat transferring effect capable of deflecting the flow in some degree, thermal impact when the flows join again can be properly controlled and minimized.
