Selection

Module from the Refractory and Insulation Curriculum curriculum.

Module 2 - Refractory Selection by Service · Learning Objectives · 1. Select refractory by operating temperature and severity · 2. Match erosion resistance for catalytic service (FCC, reformer) · 3. Consider chemical attack (alkali, hydrogen, sulfur) · 4. Design for thermal cycling (heater heat-up/cool-down stress) · 5. Specify anchor system and expansion joints · Refractory Selection by Service

Service	Primary Type	Backup	Erosion	Temp F	Notes

FCC riser	Super-hard hex mesh	Insulating	Severe	950-1050	V & T cycling
FCC cyclone (1st/2nd)	Hex mesh tile	Insulating	Severe	1000-1350	Anchoring tile
Fired heater convection	Ceramic fiber module	Mineral fiber	None	1100-1400	Dry cycling
Fired heater radiant wall	Insulating castable	Calcium silicate	Low	1800-2200	Radiation protection
Fired heater radiant floor	Medium-weight castable	Insulating	Moderate	1800-2200	Reboiler drop
Reformer furnace	Fibrous module	High-alumina brick	None	1700-1900	Steam reforming
