2021
ChemEngineering
Preserved Fulltext
The simulation of pet-coke combustion was carried out by using Fire Dynamics Simulator software (FDS) version 5.0. ...
It was shown that the calculated net power of the ORC cycle is similar to the net power reported in the literature (relative error of 4.8%). ...
It was found that the pet-coke particles are mostly applied in the Heat Recovery Steam Generator (HRSG), in Integrated Gasification Combine Cycle (IGCC) [7] , in Circulating Fluidized Bed (CFB) power ...
