AI Technical Summary
Technical Problem
The existing refractory materials in the throat of the gasifier are prone to degradation in high-temperature and corrosive chemical environments, leading to frequent replacements and increased downtime and maintenance costs.
Method used
A substantially cylindrical cooling coil is introduced at the throat of the gasifier. It maintains thermal contact with the throat refractory material through the cooling chamber and uses the coolant for indirect heat exchange. This controls the temperature and pressure of the coolant and extends the service life of the refractory material.
Benefits of technology
This extends the service life of the throat refractory material, reduces the frequency of downtime maintenance, and lowers maintenance costs.
