Abstract
This report presents how a theoretical model of an oil-fired boiler is built. This model is built in one dimension and includes heat transfer due to convection and gas radiation from gas to a surface, conduction through a metal and convection from a surface to a liquid. The model is used to analyse how different oil fuels, both fossil and bio-based oils, affects the plant. With the assumptions and simplifications used in this model, no differences between given fuels are noted. The model is not suitable to use for analysing a specific boiler.
Regarding fossil oils versus bio-based oils it is noted that renewable oils result in a lower volume of exhaust fumes per kg fuel than the fossil oils. But the renewable oils have a lower heating... (More)

Regarding fossil oils versus bio-based oils it is noted that renewable oils result in a lower volume of exhaust fumes per kg fuel than the fossil oils. But the renewable oils have a lower heating value and thus requires more fuel for the same amount of energy. This leads to no major difference in flue gas volume per GW of energy. (Less)

Biooljor kontra fossila eldningsoljor i teoretisk modell av oljepanna
Vad händer ur ett energiperspektiv om man teoretiskt använder biooljor istället för fossila eldningsoljor i en oljepanna designad för spetslast i fjärrvärmenätet?
I dagens samhälle är intresset för att fasa ut den fossila oljan stort. Särskilt eftersom fossil eldningsolja i dagsläget ofta används för spets- och reservlastpannor inom el- och fjärrvärmeproduktion. Därför kan det vara tänkvärt att undersöka beteendet för de olika alternativen som finns till fossil eldningsolja i en modell av en oljepanna.
