Alternative Fuel for reheating furnace with aiming at CO2 mitigation
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
This paper is researching different kinds of biomass based fuels and contains a case study of a reheating furnace, furnace 301, at SSAB. The purpose was to find out which type of bio fuel was best suited for the furnace application. An experiment at KTH in Sweden was observed to better understand the process of creating a gas fuel from pellets and a mass balance was done to show the difference between using a new kind of bio mass based fuel and the current use of liquid petroleum gas. Results from the experiment and mass balance show that syngas is the fuel best suited for furnace applications as well as a general idea of how to integrate it into the furnace design. Three enlarged gasifiers, with a fuel output of 32 MW, will be needed to meet the requirements in an industrial application. If furnace 301 at SSAB would be active all year around with no stops in the production, an amount of 153760 ton pellets will be needed per year which is equal to 367407 tons of wood per year.
