The Most Comprehensive Ever! Comparison of Seven Major Fuel Costs — A Guide to Steam Boiler Fuel Selection
In the daily operation of steam boilers, fuel costs account for as much as 70%-80% of total costs. The choice of fuel directly determines a company's production costs and profit margins. Today, Jingyu Thermal Energy has compiled a comprehensive cost analysis of the seven most common fuels on the market, based on the standard of producing one ton of steam, to help you make a clear and accurate calculation.
I. Electricity
Electric boilers have a very high thermal efficiency, reaching up to 99%. Theoretically, 720 kWh of electricity is needed to produce one ton of steam, with actual consumption of approximately 727 kWh. Based on the current industrial electricity price of approximately 1 CNY/kWh, the cost per ton of steam is approximately:
727 CNY/ton
Advantages: Zero emissions, quiet operation, high level of automation. Disadvantages: Highest cost, suitable for areas with off-peak electricity pricing or as a backup heat source.
II. LPG (Liquefied Petroleum Gas)
LPG has a thermal efficiency of approximately 90%, with theoretical consumption of 65 kg per hour, and actual consumption of approximately 72 kg. With a market price of approximately 6.8 CNY/kg, the cost per ton of steam is approximately:
490 CNY/ton
Advantages: High calorific value, clean combustion. Disadvantages: Significant price fluctuations, high transportation and storage costs, suitable for areas not covered by natural gas pipelines.
III. Light Diesel
Light diesel has a thermal efficiency of approximately 90%, with theoretical consumption of 60 kg per hour, and actual consumption of approximately 66 liters. With a diesel price of approximately 7 CNY/liter, the cost per ton of steam is approximately:
462 CNY/ton
Advantages: High calorific value, fast startup. Disadvantages: Relatively high cost, significant environmental pressure, generally used only as an emergency backup fuel.
IV. Natural Gas
Natural gas is currently the most mainstream clean energy source, with thermal efficiency reaching up to 95%. Theoretical consumption is 75 cubic meters per hour, with actual consumption of approximately 78-80 cubic meters. With a natural gas price of 4 CNY/cubic meter (varies by region), the cost per ton of steam is approximately:
312 CNY/ton
Advantages: Clean and environmentally friendly, high thermal efficiency, policy support. Disadvantages: Limited by pipeline coverage, prices may rise during winter peak demand.
V. Coal
Coal has a thermal efficiency of approximately 75%, with theoretical consumption of 120 kg per hour, and actual consumption of approximately 160 kg. With coal priced at 800 CNY/ton (0.8 CNY/kg), the cost per ton of steam is approximately:
128 CNY/ton
Advantages: Low cost, stable supply. Disadvantages: Increasingly strict environmental policies, coal has been banned in many regions, requires desulfurization and denitrification equipment.
VI. Biomass Pellets
Biomass pellets have a thermal efficiency of approximately 85%, with theoretical consumption of 150 kg per hour, and actual consumption of approximately 176 kg. High-quality biomass pellets cost approximately 1 CNY/kg, so the cost per ton of steam is approximately:
176 CNY/ton
Advantages: Low cost, carbon-neutral emissions, in line with dual carbon policies. Disadvantages: Need to consider whether local biomass resources are sufficient.
VII. Wood Chips/Wood Blocks
Wood chips have a thermal efficiency of approximately 75%, with theoretical consumption of approximately 170 kg per ton of steam, and actual fuel consumption of approximately 226 kg. With wood chips priced at approximately 0.5 CNY/kg, the cost per ton of steam is approximately:
113 CNY/ton
🏆 Lowest cost! Advantages: Extremely low price for wood chips, with significant advantages in forest areas or wood processing clusters. Disadvantages: Lower thermal efficiency, large volume makes transportation inconvenient.
