As a trusted biomass and coal co firing boiler manufacturer, we deliver high‑efficiency boiler systems that blend renewable biomass with conventional coal to meet stringent emissions targets while preserving plant output. Our units are engineered for utility‑scale power generation, industrial process heat, and district‑heating networks, offering flexible fuel ratios, robust combustion chambers, and long‑life heat‑transfer surfaces. Every boiler is fabricated to order, allowing you to match capacity, pressure class, and duty cycle to the specific demands of your operation.
Co‑firing integrates finely ground biomass pellets or chips with pulverized coal in a single furnace. The burner system alternates or simultaneously injects the two fuels, maintaining a stable flame front and optimal flame temperature. Real‑time control software monitors oxygen, CO₂, and flue‑gas temperature, automatically adjusting the fuel mix to achieve the target carbon‑reduction level (typically 10‑30% biomass). The heat released is transferred to a water‑wall or economizer, producing steam at pressures up to 30 MPa, which can drive turbines or provide process heat.
| Parameter | Typical Range | Customizable Options |
|---|---|---|
| Steam Capacity | 5 – 250 t/h | Up to 500 t/h on request |
| Operating Pressure | 1.0 – 30 MPa | Supercritical & Ultra‑supercritical designs |
| Fuel Ratio (Biomass : Coal) | 10 % – 30 % (by heat) | 0 % – 50 % based on boiler geometry |
| Efficiency (HHV) | 85 % – 92 % | Optimized heat‑transfer surfaces for >93 % |
| Emission Limits (SO₂, NOₓ) | ≤ 200 mg/Nm³ (SO₂) & ≤ 150 mg/Nm³ (NOₓ) | Selective catalytic reduction, flue‑gas desulfurization |
| Design Life | 25 years (continuous) | 30‑40 years with periodic refurbishment |

Our co‑firing boilers are deployed across a range of sectors where reliable steam or hot water is critical:
We work on a project‑by‑project basis; there is no fixed MOQ. Small‑scale units (5 t/h) are feasible for pilot plants, while larger orders benefit from volume discounts.
Yes. Our engineering team can adapt the burner geometry, feed system, and ash handling to accommodate wood chips, agricultural residues, or pelletized feedstock.
Standard designs ship within 15‑45 days after the engineering contract is signed. Fully customized solutions require 90‑120 days, depending on design complexity and material availability.
All boilers come with a 24‑month comprehensive warranty covering manufacturing defects. We also offer optional extended service contracts, on‑site training, and 24/7 technical hot‑line support.
