Ignition of waste / biomass mixtures deposited as dust layers
Research Areas
  • Engineering
The main objective of this research is to determine the risk of ignition of waste / biomass mixtures layers and how by adding different quantities of these materials this risk may change. To develop this, the minimum ignition temperature on layer (MITl) is used. MITl is the lowest temperature at which a layer of dust of specific thickness ignites on a heated surface and it is determined according to EN 5028-2-1. Three different samples have been used, thermally dried sewage sludge, wheat straw and wood chips, and 28 different mixtures have been studied, 18 of them with 2 components (sewage sludge with wood chips or wheat straw) and 10 mixtures of the 3 components with different quantities of each one. Sewage sludge presents lower MITl values comparing to both biomass samples, i.e. the ignition tendency of sewage sludge is higher. Results of the study show that mixtures have characteristics located in the range of the single samples and that synergistic or antagonist effects have not been observed. However, mixtures do not even present values as low as the ones of sewage sludge, but they reach the maximum values of biomasses.
