A 5-ton gas-fired steam boiler typically consumes 400–500 Nm³ of natural gas per hour at standard operating pressure (0.7–1,0MPa). Fuel consumption depends on steam load, eficiência, e condição da caldeira. O isolamento adequado e a manutenção regular podem reduzir os custos de combustível em 5–10%, especialmente em climas tropicais como o Vietnã.
Factors Affecting Fuel Consumption
- Boiler efficiency and load
- Pressão e temperatura do 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
