The invisible hydrogen flame

With greenhouse gas emissions posing a greater risk each day, serious changes have to be made to stop irreversible damage.

One possible solution is the replacement or supplement of the climate-change-contributing natural gas, with the clean and emission-free hydrogen gas. The intermediate problem coming with this solution is that hydrogen gas burns with an almost invisible pale blue flame - which is not ideal for domestic applications such as cooktops.

In this project, the goal was to find conditions under which the hydrogen flame could be manipulated to give a suitable visibility. This was achieved by manipulating various conditions such as: gas flow rate, flame port area, premixing, background colour and the supplementation of impurities. We have now found the ideal set of conditions for which a hydrogen flame should be used in the household.
