Modelling of a Torrefaction Process Using Thermal Model Object

So far, the torrefaction process has been merely discussed based on physical and chemical characteristics of final product, but mechanism not yet pondered investigated. Thus microwave predominately used for thermal pre-treatment; therefore, a paradigm shift in methodology introduced by using Joule heating system. The article mainly focuses engineering aspect process. densified black pine underwent pre-treatment at temperature 523 K. furnace was initially improvised to carry out degradation quasi-static/dynamic conditions. A 3D PDE model developed determine numerical solution distribution across pellet. To compare effect linear ramping profile, time-dependent as well fixed Dirichlet conditions were applied proposed model. mass distribution, duration process, Nusselt Reynold’s number inert gas, history are some factors whose influence simulation its heat transfer characteristic examined with help model, whereas diffusion product reactions determined solving partial differential equations discretisation method (PDEPE). densification performed ring die, initial milling biomass carried 1.5 mm sieve size. system found have homogeneous energy time, amplitude flux along radial direction reduced 15% if same pellet 5 min dynamic mode. Similarly, 64.46% drop azimuth plane could be seen while performing history. However, relative centre estimated lowered 98.41% vertical axis quasi-static condition. net change fraction carbon dioxide boundary film 40% higher than that monoxide. rate monoxide increased 7–11% increase time. 6.8% rise evaporation water noticed during first half interval (from 10 min). In second half, from 15 min, it 5.8%. 17.24% state
