I have done non catalytic supercritical water gasification experiments, and in order to have a better energy-economic analysis in my experiments, i have calculated physical and chemical exergy of biomass and gaseous, liquid and solid products of supercritical water gasification, to calculate exergy efficiency of process via the following equation: Exergy Efficiency= { Ex(syn-gas) + Ex(bio-oil) + Ex( Hydro-char)/ Ex( raw biomass) + Ex( electricity) } *100. ,but i dont have any idea about ٍElectrical Exergy calculation, in summary i want to calculate Electrical Exergy of a 3000 watt heater which rises the reactor temperature from the ambient temperature to about 873K.
Hello, I'm just a student about to enter year 3, but I want to try to help, maybe I can learn something too! May I ask if by electrical energy, do you mean like voltages? Or maybe joules? As 3000 watts would we 3000 joules per second
To reach temperature 8000K from ambient depending on the weather variations, the furnace media condition would required, different time to reach 8000K, hence energy could be calculated as E = W(t) watt hours(KWH), t the time needed and W= 3000....
Reuben Tan you are right but i'm looking for Exergy analysis which means useful part of energy
thank you for your attention
