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.

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.
