Our solutions

Nippon Gases offers 100% oxyfuel technology to improve your productivity, increase melting rate and reduce emissions.

100% oxy-fuel technology uses best in class oxyfuel burners to optimise furnace combustion capacity, improve your melting rate and reduce your NOx/CO2/CO emissions. Diluted combustion technology make possible to get adequate levels of NOx/CO2/CO and, at the same time treat scrap with high levels from organic components.

Stoichiometric ratio adjustment

- Diluted combustion is promoted.
- Not create hot spot on the crown.
- Reduce flue gas volume by 74%.
- The solution for large productions.

Reduce NOx emissions

- Allows to reduce almost 50% energy consumption.
- Ability to melt high organic scrap.
- Improve heat transfer.

An alternative to conventional air-fuel combustion

Offers a low cost, low maintenance option that can be installed on all air-fired furnaces independently of the kind of burner you are using today.

At the same fuel input, 100% oxy-fuel combustion reduces by 74% the flue gas volume. No need for regenerators of recuperators. Ability to melt high organic scrap. Increase melting rate up to 50%.
