Heat Generation 1

Heat Generation : In a boiler this is directly proportional to the availability of carbon per second to combustion
More carbon, higher the combustion and vice versa (considering availability of sufficient O2
Carbon availability is again dependent upon the lattice strength between carbon atoms, rate of breaking of lattice strength to release carbons, auto ignition temperature and carbon saturation in the fuel source

Heat Generation 2

The carbons will not be released consistently due to its own inherent properties mentioned in the previous slide which cannot ensure regularity in availability of carbon
The oxygen availability though is regulated by VFD, blowers etc is consistent
In the above equation of uneven carbon availability but regulated availability of O2 the combustion and heat availability behavior also will proportionately alter or will proportionately be influenced

Heat Generation 3

Since Carbon availability is dynamic, simultaneous existence of these conditions occur in the combustion system
1. No of carbons released = O2 available for combustion
2. No of carbons released < O2 available for combustion
3. No of carbons released > O2 available for combustion
The probability of carbon combustion matching to that of O2 availability is remote hence the combustion behavior is ever changing
Most of the time either carbons exceed the O2 availability or it is O2 which exceeds Carbon availability
Hence combustion with solid carbon fuels can never be consistent or organized due to above variations

Heat Generation 4

So when combustion behavior is unpredictable so is the heat availability
In such conditions the heat availability keeps altering which is evident from variations in burning fuel feeder RPM, steam temperature, bed temperatures, steam pressure, steam quantity etc
The heat availability can be high at a point and again low at the another point
The impact of inconsistency in heat availability directly impacts boiler operations
