The principle is simple; rather than directly measuring the temperature of the flame, use it to heat up ... typical estimates for a natural gas-powered burner are in the 1,500°C range.

Firstly, careful design is needed to make hydrogen combustion stable, as hydrogen flame propagation velocity is very high — up to seven times faster than natural gas, which may lead to flame ...

There are health risks to using an open flame supported by natural gas to ... While many people might prefer gas stoves to electric ones, thanks to the instant temperature control and versatility ...
