INTEGRATED SPLIT WATER COIL AIR HEATER AND A FUEL ECONOMIZER ASSEMBLY, CAPABLE OF ACHIEVING LOW FINAL DISCHARGE GAS TEMPERATURE

摘要

PURPOSE: An integrated split water coil air heater and a fuel economizer assembly are provided to improve log mean temperature difference between water and flue gas.;CONSTITUTION: An integrated split water coil air heater and a fuel economizer assembly comprise a water inlet(20), a dividing unit, a water coil air heater, a fuel economizer(14), a mixing unit(28), and a duct. The dividing unit partitions feedwater into high-temperature low-mass first flow(22) and high-temperature high-mass second flow(24). The water coil air heater comprises one or more heat transmission loops which transmit the heat to the air. The fuel economizer comprises one or more heat transmission loops which transmit the heat to the flue gas. The mixing unit mixes the first flow and the second flow.;COPYRIGHT KIPO 2011
