Could everyone help analyze the reasons and suggest solutions?
Coal with low ash content and low ash melting point. For coals with low ash and low sulfur content, the oxygen-to-coal ratio is definitely low; does that necessarily mean that the process burners will suffer from thermal erosion?
Texaco’s experience shows that increasing the oxygen ratio can lengthen the flame, and increasing the load also has a similar effect
