Most of the mill engineers, in particular the mechanical engineers, may be quite familiar with the engineering thermodynamics associated with the biomass fired boilers that they operate daily in a palm oil mill. The heat content in the biomass fuel expressed usually as the calorific value is transferred to the water in a boiler to […]
