After years of solving combustion related problems in FBC, AFBC & CFBC boilers, I have developed an algorithm to calculate required turbulence for given boiler design & operating fuel.
Turbulence in the boiler is the key vertice in the triangle of Turbulence -- Time & Temperature.
It is the turbulence which controls rate of reaction of C & O2, & responsible for Reaction Efficiency of C & O2.
If turbulence is high, it leads to unburnt fuel being shot out of the bed, incorrect reaction efficiency, higher fuel consumption, higher Boudouard reaction, incorrect draft.
If turbulence is low, it leads to unburnt carbon being generated in the bed, incorrect reaction efficiency, higher fuel consumption, higher Boudouard reaction, adjusted draft.
Detailed analysis of turbulence conditions show that the boiler can be operated in 27 turbulence combinations.
Out of the above combination 26 attribute to incorrect operation contributed by increased or reduced fuel density, bed height, bed density, incorrect fans settings, furnace draft & only 1 combination corresponds to the right operation of the boiler.
This means the boiler can be operated incorrectly in 26 ways & it can never be realized unless the last option is exercised which is the correct one.
Trial & errors can be eliminated directly with an equipment which can provide guidance in setting right the turbulence in the system.
The system which is being run following the Indirect method of Boiler Efficiency often fall into the trap of these 26 incorrect ways, since the Indirect Method is incapable of detecting operational probabilities.
If interested the equipment is available as a stand alone Automation System, or Add on to an existing operation system, which on command can take over the operation & set it perfectly.
For an Add On system, this equipment requires entire boiler design data & will capture the operational data from the DCS & then advise the operators to correct the operations.
