Project Description

We manufactured complete stationary part assembly including:

  • Stationary union
  • Front plate
  • Guide tube
  • Retraction assembly
  • Diffuser/flame stabilizer

The purpose of the diffuser is to impart a rotational effect to the primary combustion air zone creating the necessary vortex for flame stability and for mixing the fuel and air required for good combustion.

The diffuser is carefully matched with the register divergent section in order to achieve the optimum performance with the least waste of pressure energy.

The blade shroud prevents the free radial flow in the space between adjacent blades and reduction large turbulent streams. The angle of the air foil shroud reduces the separation between the airflow through the diffuser and airflow around it promoting early confluence of the steam line flowing inside and outside the recirculating zone of the air envelope.

The diffuser hub on which the blades are mounted projects forwards and is profiled to suit the atomizer in order to eliminate the reverse eddies which cause fuel deposits and fouling growths on the atomizer and diffuser.  This is important in the case of wide turndown.


The fuel is burnt in an airstream inside a Combustion Chamber. the heat input into the Combustion Chamber is at a not constant level and requires to be varied according to the output requirements. The Combustion equipment must be able to operate at different heat release rates, and the flame must be stable over these load ranges. The desired feature of CCE&CE diffusers is their combustion stability over wide load ranges.
