In a Clayton Steam Generator the steam is formed by pumping water through a heated helical coiled steel pipe. This results in rapid steam formation and efficient heat transfer. Unlike the firetube boiler design the Clayton Steam Generator does not store a large quantity of hot water under pressure and it is therefore much smaller in size and weight so there is also less mass of water and steel that needs to be heated up before steam is produced.
An added benefit of the design is that the steam is of high quality since it is virtually dry saturated and this makes it ideal for the heat-setting technique.
When the standby unit is not required it is switched off but it will automatically stir into action when required since the start time is only five minutes from a completely cold condition. By comparison firetube boilers can take over two hours to heat up from cold and the old standby boiler at the mill had to be kept warm all of the time, and consuming fuel, just in case is was needed.
The space required for the new Clayton Steam Generators is one quarter of room needed for the old boilers and the new steam system is housed in a modern plant room near to the point of use.
Clayton equipment has an enviable reputation for reliability and the Clayton Steam Generators at the plant are regularly inspected by Claytons own engineers who are dedicated trained specialists.
