What Causes Clinkers in Coal Fired Boilers? | Hunk
Some companies are offering chemical combustion enhancers to be added to coal that they claim will virtually eliminate clinker formation from burning lower-quality coal. These compounds act as a chemical catalyst that uses the moisture inherent in solid fuels to increase the temperature of combustion and thereby greatly reduce the amount of unburnt matter that otherwise would just melt to form clinkers.Get a Quote
