Clayton’s unique equipment and system design results in many significant advantages compared to other types. A variety of steam/water systems can be tailored to best fit each application. All of the systems, however are based on the use of the same design elements that are used in all of our steam and hot water products. Namely: counterflow of feedwater and exhaust gas; controlled feedwater circulation; spirally wound, smooth-tube heat exchanger design; and mechanical separation of the saturated steam and water.



Advantages Include:

  • Compact and Light Weight
    Resulting from the fact that there is relatively low water volume in the system. Vertical or horizontal installations available.
  • High Thermal Efficiency
    Resulting from the inherent design of the equipment and system. Provides more value in equipment and installation costs.
  • Rapid Start-up
    Results from the low water content and heat exchanger design
  • Easy To Clean
    Results from the smooth tube design that soot removal relatively easy. Soot blowing can be accomplished while operating, using our integral soot blowing system.
  • Soot Control
    Soot can provide a serious safety hazard that is minimized with the use of the smooth tube heat exchanger design and operation of the integral soot blowing system.
  • Operate Dry Up To 840oF
    Our system can run dry (without feedwater), continuously, with exhaust gas temperatures up to 840ºF (450ºC) and with even higher temperatures for limited periods of time. This eliminates the need for exhaust gas by-pass dampers in applications that do not have continuous need for steam or hot water.
  • Wide Equipment Selection
    Clayton’s modular design, combined with the large number of module sizes results in a large equipment selection that allows tailoring the equipment and system to meet a broad variety of specific applications. This results in the application, whether it be maximum heat recovery, minimum capital cost, or somewhere in between.
  • Safety
    The unique Clayton design is inherently safe with no possibility of a hazardous steam explosions.

The Clayton Exhaust Gas Boiler (EGB)

 

The Clayton Waste Heat Recovery System can be used to generate steam or high temperature hot water. Typical combinations of an exhaust gas or waste heat unit with a direct fired steam generator are shown on page 5. A principal feature of the Clayton Waste Heat Recovery System is its unique coil design. The coil tube is wound in a spiral pattern with closely controlled spacing between turns. This provides the desired area to control the velocities of the boiler gases. This highly efficient heating surface arrangement minimizes size and weight requirements.



The Clayton Exhaust Gas Boiler (EGB) is primarily used in conjunction with a Prime Mover, such as a Turbine or Internal Combustion Engine (100 kW to 15 mW), as part of a Distributed Generation installation producing electricity or in marine/ship-board applications. The typical Clayton EGB is constructed of individual coil modules, with each module containing spirally wound layers. The number of modules used depends upon the exhaust gas flows, allowable back pressure and on the boiler heat output requirements in steam or hot water.

The Clayton EGB module is available in various sizes and configurations to meet individual requirements.

Clayton EGB modules can operate at temperatures up to 1,200ºF (650ºC) and can run dry (without circulating water in the tubes) at temperatures up to 840ºF (450ºC).

Once assembled with the appropriate coil modules, the completed Clayton EGB includes inlet and outlet cones that permit vertical or horizontal units with exhaust gas flows in any direction.


The Clayton Waste Heat Steam Generator (WHSG)

 

For exhaust temperatures over 1,200ºF (650ºC), the Clayton Waste Heat Steam Generator (WHSG) is applied. The Clayton WHSG is primarily used on incinerators, furnaces and thermal oxidizers with exhaust temperatures up to 3,500ºF (1,925ºC). The Clayton WHSG is designed much like the standard Clayton direct-fired Steam Generator with water-walls and air-cooled shells. Inlet and Outlet casing and connection pieces complete the unit for installation in the client’s ductwork.
