​​1 Ton Steam Gas Use: Boiler Efficiency & Consumption

​​Answer:​​
The gas consumption depends on the boiler’s ​​thermal efficiency​​ and the ​​calorific value of natural gas​​. Using a calorific value of ​​9,140 kcal/Nm³​​, the calculations are adjusted as follows:

1. ​​Basic Formula​​:
   Gas consumption (m³) = (Heat required per ton of steam) / (Calorific value of gas × Boiler thermal efficiency)
   Note: The heat required to produce 1 ton of steam is approximately 600,000 kcal.
2. ​​Traditional Boilers (75-80% efficiency)​​:
   • At 75% efficiency:
     $600,000\text{kcal}/(9,140\text{kcal/Nm³}\times 0.75)\approx 87.5\text{m³}$
   • At 80% efficiency:
     $600,000\text{kcal}/(9,140\text{kcal/Nm³}\times 0.80)\approx 82.1\text{m³}$
     ​​Range​​: ​​82–88 m³ per ton of steam​​
3. ​​Condensing Boilers with Heat Recovery (90-95% efficiency)​​:
   • At 90% efficiency:
     $600,000\text{kcal}/(9,140\text{kcal/Nm³}\times 0.90)\approx 73.0\text{m³}$
   • At 95% efficiency:
     $600,000\text{kcal}/(9,140\text{kcal/Nm³}\times 0.95)\approx 69.1\text{m³}$
     ​​Range​​: ​​69–73 m³ per ton of steam​​

​​Practical Example​​:
Fangkuai Boiler’s condensing gas boilers (with optimized heat recovery) can achieve even lower consumption, such as ​​65–73 m³ per ton of steam​​, depending on operational conditions.
