Handling of impregnated waste wood and characterization of ash residues after combustion of the wood

In the next ten years the amounts of waste wood impregnated with Cu, Cr and As (CCA) is expected to increase dramatically world wide. CCA has been widely used for wood preservation since the early 1950s and because the fixation of CCA in the wood is good, the concentration of CCA is still high, when the wood is at the end of service. In some countries e.g. Denmark and Norway, the use of As for ...

Dangerous (toxic) atmospheres in UK wood pellet and wood chip fuel storage

There is growing use of wood pellet and wood chip boilers in the UK. Elsewhere fatalities have been reported, caused by carbon monoxide poisoning following entry into wood pellet storage areas. The aim of this work was to obtain information on how safely these two fuels are being stored in the UK. Site visits were made to six small-scale boiler systems and one large-scale pellet warehouse, to a...

Effects of Some Wood Chip Properties on Pulp Quality

A series of TMP experiments were performed at CIPP’s TMP pilot plant, and some pulp properties were measured. By comparing chip and pulp properties, and using projections to latent structures (PLS) analysis, we were able to demonstrate that on-line CMS measurements can be used to predict some pulp properties. It should be pointed out that the focus of this paper is to show how CMS measurements ...
