Konstruktion av fackla för biogas

Sammanfattning

Värmekollektor in Sunne is a company whose main occupation is to collect the gas produced in

landfills. The gas contains about 50 % of Methane which is a greenhouse gas 20 times worse than CO

2

and should therefore not be allowed to leak into the atmosphere. The Methane is in as large amount as

possible used in different plants for example heating of households. But there are occasions when a

flare is needed to burn the excess gas at standstills or testing of new landfills. The Flare only burns the

methane to reduce the hazarder’s effect of the environment, it does not take advantage of the energy in

the gas

The goal of this master thesis was for me to create a foundation for an in-house production of

flares for Värmekollektor. There was a desire to be able to manufacture there own flares so that costs

could be reduced and the performance of the flares controlled.

The target was that in the end present all drawings needed for the manufacturing and to achieve

this research had to be shortened. There was no time to create the perfect flare. The flares presented in

this report could be seen as a first step in a development process. No testing of the burners has been

done to confirm there behavior and therefore no guaranties can be made regarding the performance of

the flares. The two flares are similar to each other and they share many components. What separate

them are the principals of the burners. One is equipped with burner tubes and the other uses a

combustion chamber with swirl.

The result is two dark flares that hopefully meet the demands set upon it and two burners that

easily can be adjusted to fit open flares.
