Control of combustion
The precise mixture of the components of combustion is one of the most critical steps in modern steam production.
In the Clayton Steam Generator gaseous or liquid fuels are blended with combustion air under mechanical control and electronic supervision at fixed ratios. Air, fuel and feedwater are modulated simultaneously to follow demands for steam.

The flame is confined to the combustion chamber by burner design. Combustion is completed before releasing the products of combustion across the tubes for heat transfer. The burner manifold is bottom mounted through the refractory base of the combustion chamber. High velocity combustion air enters around the burner manifold from below in a whirlpool vortex pattern, picking up the fuel from the burner and forming a heat shaped flame pattern.
Burner and blower assembly
A portion of the flame folds back on itself in the center of the circular combustion chamber assuring complete ombustion to provide maximum heat from the fuel to the boiler water.
