Boiler Specs: firetube_oil
Boiler performance specifications — thermal efficiency, turndown ratio, operating pressure, flue gas temperature, and fuel input rate by boiler type and output capacity (MBH)
| boiler type | capacity range MBH | flue gas temp F (F) | fuel input rate MBH (MBH) | notes | operating pressure range psig (psig) | thermal efficiency pct (%) | turndown ratio (dimensionless) |
|---|---|---|---|---|---|---|---|
| firetube_oil | 100 | 430 | 123 | 100 MBH oil-fired firetube; No.2 fuel oil; 3-pass scotch marine; non-condensing; residential/light commercial backup heat; Burnham Commercial Series 3 oil or Cleaver-Brooks CB oil; minimum flue temp 350F to avoid acid condensation | 15 | 81 | 3 |
| firetube_oil | 200 | 440 | 247 | 200 MBH oil-fired firetube; 3-pass; No.2 oil; non-condensing; light commercial; Cleaver-Brooks CB oil 6HP equivalent; dual-fuel (gas/oil) common for this size range | 15 | 81 | 3 |
| firetube_oil | 500 | 430 | 610 | Firetube oil-fired boiler 500 MBH output; No.2 fuel oil; lower efficiency due to higher sulfur content requirement to prevent acid condensation; minimum flue temp 350F to avoid acid dewpoint; LPHW or steam | 15 | 82 | 3 |
