Steam exploded black pellets

Steam exploded black pellets made from biomass are a renewable fuel that offers significant reductions in carbon footprint by replacing fossil fuels. It is also a cost-effective alternative to white pellets. Black pellets involve only minor alterations to the heat and power plant and can replace existing fuels up to 100%. Valmet delivers complete production plants, from biomass receiving to finished black pellets.

Maximum value from renewable raw materials

Black pellets act like coal

The primary utilization of black pellets, or bio coal, is for replacing coal in power plants. Black pellets act like coal and can be co-fired with coal up to 70% in larger units and up to 100% in smaller units.

Advantages of steam explosion

Steam explosion, i.e., short thermal treatment ended by rapid depressurization, is applicable for upgrading many types of woody materials into a drop-in fuel. The process is an excellent choice for production of durable and waterproof black pellets that are suitable for safe and economical long distance transportation.

Steam exploded black pellets require minimal capital expenditure at the power plant. The process is easy to integrate with other industrial processes, for instance at a kraft pulp mill. Utilization of residual biomass and low-grade waste heat makes the process very feasible.
