We manufacture complete stationary part assembly including:
- Stationary union
- Front plate
- Guide pipe and seal 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 shrouds prevent 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 air flows through the diffuser and air flow 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.
