Handling characteristics of coal/biomass mixes: measurements and establishing benchmarks.
… by the power generation industry in the area of handling of coal/biomass mixes for co-firing. This project looked into two types of coals (Russian and Dawmill) and two types of biomasses (cereal co products (CCP) and milled palm nuts (MPN)) that are being extensively co-fired (as a mix) in the UK …
