Designed to ensure optimum natural circulation without water circulating pump, this type of heat recovery steam generator(HRSG) is available for recovery heat utilization either with or without supplementary fuel firing. Natural circulation type heat recovery steam generators feature:
- Self-standing structure dispensing with external framing.
- Savings in auxiliary power and maintenance costs that would be required for water circulating pump.
- Drainable vertical straight tubing arrangement.
- Spiral finned tubing for enhanced heat transfer and compact design
