Overview
This case study demonstrates how a leading food processing company successfully replaced its aging coal-fired system with a high-efficiency 4-ton biomass steam boiler, significantly lowering operating costs while meeting strict environmental regulations. The switch to biomass energy not only improved steam reliability but also helped the company achieve long-term sustainability targets.
Client Background
Company: GreenHarvest Foods Co., Ltd.
Industry: Food Processing
Annual Production Capacity: 120,000 tons of finished goods
Energy Demand: Continuous steam supply for sterilization, drying, and packaging
GreenHarvest had relied on a traditional coal-fired boiler for more than 12 years. Rising fuel prices, tightening emissions standards, and unstable steam output pushed the company to search for a cleaner, more cost-effective solution.
Challenges
Before adopting a biomass steam boiler, the company faced several issues:
- High fuel expenses due to fluctuating coal prices
- Low thermal efficiency (63%) resulting in energy waste
- Frequent maintenance and downtime
- Difficulty meeting local emission regulations
- Inconsistent steam pressure affecting production quality
The company needed an energy system that was stable, compliant, and cost-efficient.
Solution: Installation of a 4-Ton Fully Automatic Biomass Steam Boiler
After technical evaluation, GreenHarvest selected a 4-ton fully automatic biomass steam boiler featuring:
- High thermal efficiency (88%+)
- Low NOx and dust emissions
- Automatic feeding system compatible with wood pellets, palm shells, and agricultural residues
- PLC control for stable steam output
- Integrated economizer and air preheater to improve heat recovery
The boiler was designed to operate with locally sourced biomass fuel, reducing transportation and procurement costs.
Implementation Process
- Energy audit and load analysis to accurately size the boiler
- Customized furnace design to match the plant’s fuel type
- On-site installation completed in 22 days
- Operator training and safety certification
- System optimization during the first month of operation
The transition from coal to biomass required minimal changes to existing pipelines, keeping installation costs low.
Results
After six months of operation, the biomass steam boiler delivered measurable improvements:
✓ 42% Reduction in Fuel Costs
Switching from coal to wood pellets cut annual fuel expenses from $580,000 to $335,000.
✓ 30% Increase in Thermal Efficiency
The new system achieved 88% efficiency, reducing fuel waste and improving steam availability.
✓ 100% Compliance With Emission Standards
Dust, SO₂, and NOx emissions stayed well below local regulatory limits.
✓ Stable Steam Output
Steam pressure fluctuations dropped by 60%, improving product consistency.
✓ 20% Lower Maintenance Costs
The automated feeding and ash-handling system reduced manual labor and equipment wear.
Environmental Impact
By replacing coal with biomass, the company reduced CO₂ emissions by over 4,800 tons per year, supporting its annual sustainability goals and improving its corporate environmental image.
Client Testimonial
“The biomass steam boiler has transformed our energy system. We achieved lower costs, cleaner production, and more stable steam output. It was one of the best investments we’ve made in the past decade.”
