Optimize transient plant operations with castable-free fired heater
Fired heaters are designed with castable refractory in various sections of the heater.
Transient analysis of fired heater coils to estimate safety time
During the operation of process fired heaters, the potential exists for sudden interruption of process flow.
Revamp fired heaters with a common air-preheating system to increase capacity
In any process plant, fired heaters are generally considered to be one of the most optimally designed pieces of equipment.
Successfully design fired heaters using ultra-low-NOx burners
Recent environmental regulations mandate that refinery and petrochemical industries reduce nitrogen oxide (NOx) emissions. Emissions legislations are constantly under review, and they differ from coun..
Identify and control excess air from process heaters
Process heaters are the largest consumers of energy in most plants. A refinery, on average, burns approximately 2 billion Btu/hr of fuel in fired heaters. The total quantity of fuel burned (heat relea..
