FLY AND BOTTOM ASH
The ECOBIK® influence of the resulting products of combustion was evident in all applications tested.
In all cases, the quantities of fly and bottom ash with ECOBIK® were lower than before ECOBIK®, and parameters that changed were: pH being always changed towards a value closer to neutral pH and the quantity of carbon in ash was always reduced.
The quantities of certain elements resulting from the combustion were lowered in the following way:
For combustion of heavy liquid fuels (removed deposits were analyzed):
- total sulfur by 60%;
- dioxide of silica by 25%;
- calcium oxide by 90%;
- magnesium oxide by 90%;
- sodium oxide by 75%;
- potassium oxide by 50%;
- vanadium oxide by 85%;
For coal combustion, interesting findings of the fly and bottom ash were obtained, especially changes in the amounts of some heavy metals within fly and bottom ash, for example:
Particulate & heavy metals effects = BONUS
The results are from the combustion of waste bituminous coal, with high levels of sulfur (3% to 5%), initial ash about 50% in fluidized bed combustion.
