Direct Combustion
Direct burning fully oxidises biomass to produce heat. It can generate particulate, NOx, CO and carbon-dioxide emissions, provides limited control and is comparatively inefficient for power-only generation.

Biomass Gasifiers
A simple, reliable route from solid biomass to clean, controllable producer gas—with the potential to reduce conventional fuel costs by over 50%.
Clean biomass conversion Infinite gasification systems
Replace expensive fossil fuels with low-cost biomass.
The gasifier is a chemical reactor in which pyrolysis, controlled combustion and reduction convert solid biomass into combustible producer gas.
The gasifier can be isolated from the combustion system and producer gas piped to ovens or furnaces. Fuel handling and ash removal can therefore remain away from the working area.
Producer gas can replace furnace oil, LDO, diesel, LPG or CNG in specially designed burners without changing the process temperature profile or plant cleanliness.

What is biomass gasification?
From conventional combustion to controlled gasification.
Thermal Gasification
Gasification reacts carbonaceous material above 700°C with a controlled quantity of air or oxygen, producing a flexible gaseous fuel that burns cleanly and can be controlled like conventional liquid or gas fuel.
Typical producer-gas composition
18–20% Carbon monoxide15–20% Hydrogen1–5% Methane9–12% Carbon dioxide45–55% Nitrogen
Typical calorific value: 1,000–1,200 kcal/m³.
Gasification process
Four zones. One continuous conversion.
Each stage occurs in a distinct zone as biomass travels through the reactor.
Drying
At 150–200°C, heat from lower zones evaporates moisture from the feedstock.
Pyrolysis
At 400–650°C, cellulose and lignin break down into hydrocarbons and char.
Oxidation
Injected air supports heat-releasing reactions at 900–1,200°C and destroys a substantial portion of tar.
Reduction
Endothermic reactions form the final producer gas, which exits at approximately 250–500°C.
Infinite advantage
Designed for practical industrial operation.
Unique features make Infinite gasifiers a strong solution for industrial heat and power.
Simple start-up
Easy loading and automated start control help the fire build quickly and efficiently.
Clean producer gas
Clean gas reduces heat-exchanger maintenance and supports direct-fired heating and drying.
Low particulates
Typical particulate levels below 50 mg/m³ may reduce downstream pollution-control needs, depending on fuel.
Up to 91% efficiency
Purpose-engineered reactor geometry delivers high conversion efficiency on selected models.
Indirect gas cooling
No water-based gas cleaning means no sticky tar-contaminated cooling effluent to handle.
Hot-gas filtration
Optional fine filtration cleans hot gas up to 600°C with over 96% efficiency for particles above 10 microns.
Compact footprint
A typical 600 kWth complete system occupies about 20 × 20 ft, excluding fuel storage.
High turn-down ratio
Output can reduce to approximately one-third of maximum capacity while remaining stable.
Quick start & shutdown
Reach 75% capacity within 30 minutes of cold start; typical shutdown is under 15 minutes.
Idling capability
Standby operation handles low-load periods and enables a rapid return to full capacity.
Low operating cost
Simple equipment, fewer moving parts and lower gas velocities reduce maintenance demand.
Automated control
User-friendly controls manage gasification and regulate supply safely to burners or engines.
Optional automation
Control matched to the process.
Load synchroniser
Regulates gas generation to match demand, preventing excess pressure or insufficient heat and reducing flaring.
Automated filter operation
Helps prevent filter choking and dust carry-over.
Load-following control
Automatically adjusts gas generation and fuel consumption to the thermal load.
