The coil is a single water tube which is stacked in spirally wound layers in the upper section of the Clayton Steam Generator and forms a ‘water wall’ around the combustion chamber of the lower section. The configuration of the coil as well as the variation in the tube diameter, spacing between layers and spacing between tube turns in different temperature zones of the coil are all carefully designed to maximise efficiency and thereby minimising fuel consumption
