Design of Methodology for Wood Chips Moisture Evaluation

Article Preview

Abstract:

Moisture is an important factor of evaluating of burning process efficiency. Unfavorable moisture increases the requirements for energy/fuel consumption which is needed to evaporate water and in a negative manner affects the volume of exhaust gas, the amount of water vapor in exhaust gas as well as the increase in the temperature of the exhaust gas dew point. Thus, wood chips moisture monitoring is a diagnostics tool suitable for the evaluation of operating parameters and a combustion process. The article deals with the design of an appropriate method of measurement and evaluation of wood chips moisture and compares two methods of moisture determining. The problem of moisture determining consists mainly in selecting a suitable method according to the estimation of content of water in wood chips. Another factor to be considered is the fact that moisture in wood chips due to the ambient conditions (temperature, pressure, humidity) changes over time.
