Drying & Energy Recovery Equipment for Biomass Plants

Biomass energy facilities — from wood pellet mills and sawmill co-generation plants to dedicated biomass power stations — require significant drying capacity before combustion or pelletisation. Wood chips and agricultural residues typically arrive at 35–55% moisture content and must be dried to 8–12% for efficient combustion or pelletisation. Flash dryers are the preferred choice for fine wood particles (sawdust, shavings) where rapid, even drying is needed. Rotary drum dryers handle coarser wood chips and bark.

HRSG (Heat Recovery Steam Generator) and WHR (Waste Heat Recovery) systems capture heat from biomass boiler flue gases, engine exhaust or process gas streams — converting waste heat into useful steam or hot water. In a typical biomass plant, integrating an HRSG into the flue gas path improves overall plant efficiency by 20–35%. Lozzar Process designs the HRSG to match the specific flue gas temperature, flow rate and steam demand of each installation.
