The tall oil pitch that will be used within the pelletizing plant contains high-boiling esters of fatty acids and rosin. The use of this type of oil puts a lot of pressure on the burner systems. Tall oil is highly corrosive and requires acid-resistant materials as well as more heating due to higher viscosity.
Burning bio-oils can often lead to higher levels of NOx, but the high-pressure technique used in our Arctic Heat burners keeps the levels low. Arctic Heat has proven to have a great advantage when it comes to effectively burning these type of oils with little residues in the exhaust.
