A 5-ton gas-fired steam boiler typically consumes 400–500 Nm³ of natural gas per hour at standard operating pressure (0.7–1,0 MPa). Fuel consumption depends on steam load, eficiencia, y estado de la caldera. Un aislamiento adecuado y un mantenimiento regular pueden reducir los costos de combustible entre un 5% y un 10%, especialmente en climas tropicales como Vietnam.
Factors Affecting Fuel Consumption
- Boiler efficiency and load
- Presión y temperatura del vapor.
- Insulation of pipes and tanks
- Maintenance schedule
Tips to Reduce Operating Cost
- Regular cleaning and inspection of burners
- Optimize steam load and avoid idle operation
- Install economizers or waste heat recovery if possible
