Thermal potential simulation of wood biomass pellets used in energy generation

摘要

Due to its natural or controlled regeneration and spreading, wood represents the main source to produce biomass energy. By means of its calorific value, wood biomass is recommended to obtain energy by direct burning or other processes. Lately, technologies have been developed to ensure the production of pellets or briquettes based on wood biomass. It is necessary to study how these pellets behave when being subjected to a heating process, furthermore it is necessary to determine how the temperature develops along a segment of pellets. To make this possible, a heat transfer simulation model will be used based on two or more thermal simulation models. After entering all constants necessary to initialize and run the code in Matlab, the temperature variation diagram will be obtained according to two ideal energy sources that actually constitute the heat sources to which the pellets or their segments are subjected. The results obtained allow to determine the temperature values at which the pellet material is stabilized before it is subjected to combustion.
