Analysis of Ash Melting Behaviour (Reducing

Ash melting, also known as ash fusion and ash softening, can occur at high temperatures and is of particular importance in thermal conversion processes.The process of ash melting is complex and can involve sintering, shrinkage, and swelling. If the ash melting temperature is too low then it will lead to slagging, fouling and corrosion in boilers and that will reduce conversion efficiency.
