Boise Cascade (Pilot Rock)
30-0016 | 3 Dutch-oven boilers (Babcock & Wilcox, early 1940s), 2 @ 20,000 lb steam/hr, 1 @ 8,000 lb steam/hr; Backup to NG fired boiler. | Boiler 1: 0.08-0.17 and 0.4% (6 tests);
Boiler 3: 0.08-0.19 and 0-1% (8 tests); Boiler 4: 0.06-0.10 (4 tests) | Need uniform, dry fuel; steady load. | Company indicated concern about control device which requires an air flow system that is incompatible with natural draft stacks. Because boilers are backup, company could decide to stop using the boilers rather than control. | Different from other Dutch oven boilers with multiclones? | |
