The assessment of fire risk of non-road mobile wood chopping machines
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2019, Vol 64, Issue 1
Abstract
The increase of green infrastructure in urban areas, increases the demand for machines implementing agriculture processes. For such procedures mobile machines with internal combustion unit are most used. While working, these drives are exposed to contamination resulting from the crushing process gets through on both the engine surface and the reach high temperatures. The paper presents the results of convection testing of 400°C on pollutants originating from wood crushing process of pear, pine, aspen, oak, alder, walnut, birch, hornbeam, spruce needles, young spruce branches, leaves and young plum branches. Showing that a few minutes of exposure to the temperature can cause the emission of flammable gases and flame or flameless combustion. It was confirmed that the type of hardness of wood according to Janki's classifi-cation does not significantly affect the course of the combustion process as a result of contact with the heated surface. The described issues are significant and up-to-date, as these machines are also used in landfills and waste disposal areas, where till the end of May 2018, 63 fires were recorded.
