Safety-technical characteristics of forest residue, coal and straw. Interim report

摘要

The aim of the project is to measure and assess safety factors related to pressurized feeding of different fuels. Self-ignition characteristics of forest residue chips, coal and straw are measured in pressurized conditions. Explosion characteristics of forest residue chips at elevated initial pressure and temperatures are determined. In both cases, the effect of inertization used for preventing self-ignition and dust explosions during handling is also measured. During the first year of this two-year project, self-ignition properties of forest residue chips and coal were studied both at normal atmospheric pressure and in pressurized conditions. The effect of different types of inert gas on self-ignition temperatures at different pressures have also been studied. A survey of different possibilities to conduct dust explosion experiments at high initial pressure and temperature has also been completed
