The major safety advantage of the low water storage requirement is that there is no possibility of a steam explosion from a Clayton Steam Generator. The Clayton Steam Generator can be provided for unattended operation and a separate boiler house is not required. In addition, operation is completely automatic and the Clayton Steam Generator has a reputation for reliability and low maintenance. Principle of Operation The reason for the many advantages of the Clayton Steam Generator is, what we call, the Forced Circulation Monotube Coil Concept. This operates on a simple but ingenious principle.

The boiler feedwater is pumped by means of a specially designed Clayton Pump and is forced through a single heating coil. The steam/water mixture from the outlet of the coil is then passed to a high efficiency centrifugal separator. Steam quality from a Clayton Steam Generator is up to 99.5 % dry

saturated.

Superheat

As with all Clayton Steam Generators, feed water is directed to the topmost layer of coil from where it spirals downwards through each level to the lower part of the boiler. In this lower section, the tube forms a cylindrical shield around the combustion chamber. As the water passes through the steam generator it picks up heat and steam is produced at the outlet from where the flow is directed to a pressurised centrifugal separator vessel. The required superheat is then obtained by feeding this dry steam back to the
