Better Control of the Flue Gas Temperature before the Convection Parts

The flue gas temperature before entering the convection parts of the boiler must be under approx. 600°C before entering the super heater.

A too high temperature is caused by:

• A too high flue gas temperature at the inlet (refer to Flue gas Temperature into the Boiler)
• residues accumulating at the surface of the convection parts of the boiler, creating an isolation lining and having a double consequence: a lesser steam/energy production, and a higher flue gas temperature

Dublix Engineering can solve this problem by installing the DD-Jet Cleaning system for one or several of the empty passes of the boiler.

The achieved results are:

• A temperature at the boiler outlet reduced with 80 to 120°C
• A better operation of the boiler and the flue gas cleaning system
• More energy being generated from the circulating flue gas
