Boiler heat recovery module

Clayton Heat Recovery Steam Generators are in operation around the world serving co-generation plants, thermal oxidizers, incinerators and many other applications. Systems are able to produce high pressure steam—up to 450 psig—as well as high temperature hot water. Clayton manufactures two types of heat recovery products: Exhaust Gas Boilers Built from smooth tube modular sections similar to our fired steam generator coil sections, Clayton Exhaust Gas Boilers are capable of operating with gas temperatures up to 1000°F, and gas flows in the range of 2,500 to 150,000 lbs/hr. Clayton's modular bare tube design offers the design engineer ultimate flexibility in system configuration. By selecting from numerous potential coil sizes, a heat recovery boiler can be arranged to extract the optimum amount of heat to produce useful energy. Clayton engineers work from a comprehensive computer design program to size the heat transfer surface and feedwater requirements. The modular design allows the coil sections to be assembled to accept gas flow in either an upward or downward flow pattern. Horizontal arrangements are also available. Soot blowing and water washing systems are available for dirty gas streams such as the exhaust from heavy oil fired diesel engines. If required, Clayton will furnish a bypass system with interlocking controls. The bare tube coil design allows the heat recovery generator to operate at temperatures as high as 850°F in a dry condition.
