energy conservation in wood drying process

Wood drying 4 Wood drying Wood drying may be described as the art of ensuring that gross dimensional changes through shrinkage are confined to the drying process. Ideally, wood is dried to that equilibrium moisture content as will later (in service) be attained by the wood. Thus, further dimensional change will be kept to a minimum

Energy Conservation Energy conservation is a means of adapting the way you carry out your day-to-day activities, at work, rest and play. It also allows you to assess and adapt the environment in which you conduct these activities. Everything we do from waking up to going to bed is classed as an activity and uses some form of energy

Energy consumption in drying ranges from a low value of under five percent for the chemical process industries to thirty five percent for the papermaking operations. In the USA, for example, capital expenditures for dryers are estimated to be in the order of only $800 million per annum. Thus, the major costs for dryers are in their operation rather
