How to Adjust to Limit Clinkers? | Stoker Coal Boilers ...

Clinkers result from coal with a low ash-fusion temperature.Clinkers are when the ash "melts".Some veins will not clinker until close to 3500 degrees.When initial deformation of the ash is around 2500 or less,you will likely have clinkers.So,trying to burn your coal at a lower temp is one thing to do,by cutting back on air as long as you are ok with the heat output.If this doesn't help your ...
