Cofiring
{{Short description|Combustion of two different fuels in the same combustion system}}
Co-firing (or cofiring, also referred to as complementary firing or co-combustion) is the combustion of two different fuels in the same combustion system.{{Cite journal |last=Ekmann |first=J.

The term co-firing was popularized in the 1980s and then referred specifically to the use of waste solid residues (paper, plastic, solvents, tars, etc.) or biomass{{Cite journal |last=Sondreal |first=Everett A. |last2=Benson |first2=Steven A. |last3=Hurley |first3=John P. |last4=Mann |first4=Michael D. |last5=Pavlish |first5=John H. |last6=Swanson |first6=Michael L. |last7=Weber |first7=Greg F. |last8=Zygarlicke |first8=Christopher J. |date=2001-06-01 |title=Review of advances in combustion technology and biomass cofiring |url=https://linkinghub.elsevier.com/retrieve/pii/S0378382001001345 |journal=Fuel Processing Technology |series=Fuel science in the year 2000: Where do we stand and where do we go from here? |volume=71 |issue=1 |pages=7–38 |doi=10.1016/S0378-3820(01)00134-5 |issn=0378-3820}} in coal power stations that were designed only for the combustion of coal.{{Cite journal |last=Mann |first=M. |last2=Spath |first2=P. |date=2001-08-01 |title=A life cycle assessment of biomass cofiring in a coal-fired power plant |url=https://link.springer.com/article/10.1007/s100980100109 |journal=Clean Products and Processes |language=en |volume=3 |issue=2 |pages=81–91 |doi=10.1007/s100980100109 |issn=1435-2974}}
