I would like to ask everyone: what are the difficulties and issues in coal gasification processes that could be used as topics for a graduate thesis? Thank you
What is the relationship between the furnace temperature in water-coal slurry gasification and the ash fusion point of the raw coal? How can the problem of high ash fusion points in raw coal be addressed? What are the solutions to the issue of short service life of burners and refractory bricks?
Depending on the type of coal, its ash fusion point varies; therefore, solvents are added as much as possible to lower this ash fusion point and thus reduce the furnace temperature. In coal gasification, there are specified flow rates for the coal slurry, with the aim of minimizing wear on the pipes and burners caused by the slurry.

Cause analysis and adjustment methods for coal powder flow fluctuations
1. How can the service life of the burners used in water-coal slurry gasification be made the same as that of refractory bricks? 2. How can a gasification furnace be used with coal types that have high ash content and high ash fusion points? 3. How can the gasification process be optimized to maximize energy efficiency?
The use of evaporation to increase the concentration of water-coal slurry is something worth exploring; the United States is quite active in this area
Starting with the addition of additives, coal slurry gasification requires a high-concentration slurry; the higher this concentration, the greater the efficiency, lower the energy consumption, higher the profits, and better the energy utilization rate. It is a good topic to develop better water-coal slurry additives.

There are so many gasification processes, and each one has its own inherent flaws. Shell powder coal gasification: ash accumulation in the syngas cooler, as well as wear and damage to the burners & burner covers.
