Biomass Boiler Retrofit Case Study – 42% Steam Cost Reduction in Industrial Steam Plant (China)
1. Project Overview
This project is located in Wuhan Economic Development Zone, China.
It is an industrial steam supply system serving multiple production facilities.
- Location: Wuhan, China
- Industry: Industrial Steam Supply / Energy Service Plant
- Original System: Natural Gas Boiler System
- New System: Biomass Circulating Fluidized Bed Boiler
- Capacity: 4 × 20t/h steam boilers
- Fuel Type: Biomass (wood chips, rice husk, straw, agricultural waste)
- This project uses a high-efficiency biomass boiler system designed for continuous industrial steam supply.
⚠️ 2. Customer Pain Points
Before the retrofit, the client faced:
- Rising natural gas prices causing unstable operating costs
- High steam production cost (~380 RMB/ton steam)
- Dependence on fossil fuel supply
- Pressure from carbon reduction and energy efficiency policies
- Need for long-term stable and controllable steam cost
👉 The main objective was to significantly reduce steam cost while maintaining stable industrial operation.
⚙️ 3. Technical Solution
We implemented a biomass circulating fluidized bed (CFB) boiler retrofit system.
Key engineering upgrades:
- Replaced 4 × 20t/h natural gas boilers
- Installed biomass CFB boiler system
- Designed multi-fuel feeding system
- Enabled biomass fuel flexibility (wood chips, rice husk, straw)
- Optimized combustion system for high-moisture biomass
- Integrated advanced emission control system
System highlights:
- Stable combustion under variable biomass fuels
- Continuous 24/7 steam supply capability
- Low NOx emission design (≤50 mg/m³)
- High thermal efficiency industrial operation
- Compatible with agricultural waste fuels
- This retrofit is one of our proven steam cost reduction solutions for energy-intensive factories.
📉 4. Project Results
After commissioning:
- Steam cost reduced from 380 RMB/ton → 220 RMB/ton
- Cost reduction: approximately 42%
- Annual steam production: 500,000 tons
- Annual cost saving: around 8 million RMB
- Stable continuous industrial steam supply achieved
- Significant reduction in fossil fuel dependency
- Similar results can be achieved across many industrial biomass applications such as food processing, textile, and paper mills.
