Abstract

This project was aimed at developing an understanding of the issues faced 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 coal power plants and are known to cause a wide range of handling issues.

The key objectives of the project included: Identifying a cost effective method of flow property measurement: Developing an understanding of the flow of coal/biomass mixes, and Identifying the handling problems in bunkers and design of bunker units to suit coal/biomass mixes flow.

The main contribution of the project was the determination that caking due to mould growth over time, is a key handling issue and that different biomasses behave differently when added to coal in different mix ratios as far as caking it concerned. Another contribution is the Best Practice Guide that was prepared at the completion of the work as a recommendation to industry (which are using co-firing as method of power generation) and also for academia in the field.
