Scientists at the Faculty of Agricultural Sciences have studied the effect of the co-firing of slurry solids and straw on energy efficiency and environmental impact.

The conclusion of the scientists is that small-scale furnaces can be used for the combustion of the slurry solid fraction with straw, but that there are also some problems associated with this. The fibres often have a high water and ash content and the recommendation is therefore that the solid fraction should comprise at most 50% of the co-fired mix.

Co-firing the solid fraction with straw has a positive effect on heat production. Nevertheless, even with the largest possible quantity of slurry solids, the energy production from the fibrous fraction is only about 20% of the total energy production of the furnace, while 80% originates from combustion of the straw, the scientists point out.
