Emission results of combustion process of fatty acids distillation residue in an oil boiler – comparison to heavy fuel oil

Abstract

<jats:p>The results of the research on energy usage of the fatty acids distillation residue are presented. Distillation residue constitutes a material of biogenic origin, which is created only as a result of physical processing of animal fats without using additional chemicals. This material exhibits similar physicochemical properties as the heavy heating oil and may be its substitute. Industrial comparative tests of combusting of distillation residue and also of the heavy heating oil in an oil boiler were conducted. The research was conducted at the rated and minimum capacities of the boiler. It has been stated that combusting of the distillation residue of the fatty acids in a tested oil boiler does not bring about any technological difficulties. No threat of the elevated emission of pollutants into the atmosphere was exhibited. Installation of the boiler fulfill all emission standards required for combustion of the liquid fuels. Combustion of fatty acids distillation residue contributes to the reduction of the previous emission of pollutants from burning of the heavy fuel oil, significantly in scope of SO2.</jats:p>

Application of Fatty Acids Distillation Products as a Substitute for Heavy Fuel Oil in Stationary Combustion Chambers

“…The addition of animal fat caused slightly lower emission of NO x . Wasielewski and Głód [18] presented the combustion of the fatty acids distillation residues (FADR) and the heavy fuel oil (HFO) in a 4.5 MW th nominal capacity boiler. A slight decrease in NO x emission and a significant decrease in SO 2 emission were observed.…”
