Abstract

The main goal of the present study is to promote a more eﬀective use of agriculture residues (straw) as an alternative renewable fuel for cleaner energy production with reduced greenhouse gas emissions. With the aim to improve the main combustion characteristics at thermo-chemical conversion of wheat straw, complex experimental study and mathematical modelling of the processes developing when co-ﬁring wheat straw pellets with a gaseous fuel were carried out. The eﬀect of co-ﬁring on the main gasiﬁcation and combustion characteristics was studied experimentally by varying the propane supply and additional heat input into the pilot device, along with the estimation of the eﬀect of co-ﬁring on the thermal decomposition of wheat straw pellets, on the formation, ignition and combustion of volatiles (CO,H₂₎.
