Water-Cooled Grate Combustion System 0.5-6 MW

Handles biomass and challenging fuels up to 60% moisture, with 10–110% load flexibility and durable water-cooled grates.

## Industrial Biomass Burner – Water-Cooled Grate Combustion System

Bio Mobitek's industrial biomass burners are designed for reliable combustion of a wide range of solid fuels, from wood chips and pellets to challenging agricultural and industrial residues. Available in capacities from 1 to 6 MW, they can be supplied as standalone combustion units or integrated into complete boiler plants.

**Fuel flexibility and wide operating range**

The large, concrete-lined combustion chamber handles fuels with varying moisture content, particle size and combustion characteristics. Depending on fuel properties, moisture content can reach approximately 60%. The system operates continuously across 10–110% of nominal capacity under suitable fuel conditions.

**Advanced two-stage combustion**

Three primary and two secondary air zones enable precise combustion control for different fuel characteristics, ensuring stable operation, efficient fuel conversion and reduced emissions.

**Water-cooled grates for extended service life**

Short, moving water-cooled grates with 27% chromium content withstand demanding operating conditions. Water cooling prevents overheating, reduces thermal deformation and component wear, and ensures stable fuel movement. The concrete-lined combustion chamber provides additional protection against high thermal loads.

**Automation and emission control**

Automated fuel feeding, combustion air regulation and ash removal minimise manual intervention. The system supports flue gas recirculation and is SNCR-ready for future integration of additional NOx reduction technology.

**Flexible integration**

Bio Mobitek combustion systems can be integrated with hot-water, steam or thermal-oil heat exchangers for industrial process heating, district heating and energy recovery from production residues.

Designed and manufactured in Estonia, the system combines fuel flexibility, robust construction and long-term operational reliability.
