Abstract
An integrated water coil air heater and economizer arrangement for a boiler has a feedwater inlet for supplying feedwater to the boiler, and conduits and a valve for splitting the feedwater from the inlet into a first partial lower temperature, lower mass flow stream, and a second partial higher temperature, higher flow stream. A water coil air heater for passage of air to be heated for the boiler contains at least one heat transfer loop in heat transfer relationship with the air, the heat transfer loop of the water coil air heater being connected to receive the first partial stream. An economizer for passage of flue gas to be cooled for the boiler contains at least one heat transfer loop in heat transfer relationship with the flue gas, the heat transfer loop of the economizer being connected to the heat transfer loop of the water coil air heater for receiving the first partial stream from the water coil air heater. A mixing location downstream of the economizer receives and reunites the first and second partial streams and a conduit carries the second partial stream from the feedwater inlet to the to the mixing location.
