Test conditions & notes
- Actual evaporation is based on feedwater at 15°C and saturated steam at 0.49 MPa.
- Boiler efficiency is calculated by the JIS B 8222-1993 heat-loss method. Efficiency tolerance: ±1%; combustion capacity tolerance: ±3.5%.
- Fuel consumption is calculated using the specified lower heating value. Actual gas heating value and supply pressure affect the result.
- Gas piping must maintain adequate pressure while the boiler and other equipment operate. Supply pressure range: 0.03–0.3 MPa.
- With an economizer, a feedwater temperature of at least 50°C is recommended.
- Specifications may change as products improve. Refer to the latest technical information from Chuang Ting for final selection.
