Me again, just checking out different website, and came across Bioethanol fires. Cheap to run, for rooms, conservatories. Have you heard of these. still checking other websites.
heat is just an exothermic chemical reaction between the 'fuel' and the oxygen in the air
Typically alcohols have a chemical formula such as CH3CH2OH or C2H5OH [ methane I think is CH4 ]
Typically its the H that burns and the C, carbon, forms with additional O to form CO2 or CO if combustion incomplete.
Just wonder what happens here as from here
[broken link removed]
it seems there is no embedded carbon in bio-ethanol
