Evaluation of Fired Heaters for Cresap Testing
Coal liquefaction processes require a fired heater to heat the coal and solvent slurry mixture. A flash still preheater may also be necessary to provide the heat of vaporization required for the recovery of solvent from heavy oils. Both of these critical applications call for special attention to unique requirements for commercial plant design. These heaters operate at process conditions approaching coking temperatures of the coal particles and the heavy coal extract. Operating and maintenance costs can be adversely affected by above normal fouling of the heater tubes. The economical design of commercial units requires careful trade-offs between heat transfer area, heater life, maintenance requirements, and thermal efficiency. A test program to determine the region of fired heater design and operability is desirable. This study has ben conducted to evaluate which critical fired heater services common to coal liquefaction processes should be included in the fired heater development test program at Cresap.
