Steam Generators

The high powered Clayton Steam generator is the world’s most compact, efficient, responsive and safest way of producing high quality steam.


The Clayton Steam generator has been continually developed since 1930 and is very different from the traditional firetube boiler design that is the familiar steam train boiler image of the past. In a firetube boiler a large amount of water and steel is heated to produce steam. In the Clayton Steam generator a small amount of water and steel is heated to produce steam.

The basic design concept results in a steam making machine with staggering advantages for today’s world. The Clayton Steam generator is the best steam boiler available for all steam applications and is the preferred choice of professional thermodynamic engineers as well as many of the world’s forward looking companies and institutions who use steam in their production or processes.


Principle of operation


The basic principle of operation of the Clayton Steam generator is both ingenious and simple.


Water is pumped through the inside of a small diameter heated coiled tube so that cold water goes in one end and high pressure steam comes out of the other.


The Clayton Steam generator uses only three main components and these have been specially designed for the purpose. The boiler feedwater is pumped by means of a specially designed Clayton Pump that forces the water through the Clayton single continuous helical heating coil.

From the outlet of the coil the stream is directed to a high efficiency Clayton centrifugal Separator.


This forced circulation helical coil concept produces steam that is almost completely dry saturated. The separated water is always recycled in the Clayton Steam generator system.



The forced circulation helical coil design concept of the Clayton Steam generator produces outstanding benefits to the user.


High efficiency

Very high efficiency is the most obvious benefit that comes from small sizes because of low radiation and convection heat losses. In addition heat flow is in the opposite direction to the water flow through the coil and this counterflow principle optimises heat transfer which results in low running costs.


Small size

Compact design means that minimal space is required for a complete Clayton boiler house.

For a new installation building costs are reduced and in an existing factory a Clayton system can easily be fitted into the available area and the low weight even permits location on an upper floor level.


Rapid Start

Start up from a completely cold condition is five minutes. The warm up fuel is minimised and the unit can be switched off when the operator leaves at the end of the working day. The Clayton Steam generator is therefore also ideal when used as an auxiliary or standby boiler. 


It is not possible to have a steam explosion. This is a danger associated with low water level in other types of boiler that store a large volume of hot water. The Clayton Steam generator does not have a water level and does not store a large volume of water so the danger is completely eliminated.


High Quality Steam

Steam quality is the best available from any type of boiler and is at least 99.5% dry saturated at all steam loads. This reduces the amount of water and impurities going into the process and ensures higher energy content of the process steam.


Rapid Response

Extremely rapid response to changes in the demand for steam is inherent in the forced circulation design. A Clayton Steam generator will speedily ramp up and run at maximum steam output continuously without faltering.


Low Blowdown

Blowdown which is necessary to prevent the build up of impurities in all boiler systems is extremely small with the Clayton design. This saves fuel, saves chemicals and saves water.


Fully Automatic

The rapid start and rapid response can be controlled automatically. All Clayton systems can be started by a single switch locally or remotely just like any modern advanced machinery.


Unattended Operation

Because of the inherent safety and automatic systems all Clayton Steam generators can be supplied to run without operator attendance for up to a period of one week.


Low Maintenance

One of the practical benefits of the simple design concept is that maintenance requirements are minimal. In addition all of the components have been developed and improved over many years to make the Clayton Steam generator the most reliable steam boiler available today.
