Principle
The Steamexfire is driven by a jet engine. In a jet engine, air is compressed into a combustion chamber where fuel (kerosene) is injected. The explosive mixture of fuel and air is igniter by a sparkplug, and the expansion as a result of the combustion process, is forces towards a turbine wheel which drives the compressor. The exhaust gasses of a jet engine contains approx. 17% oxygen. In a second stage combustion chamber, more fuel is injected and ignited. As a result of this process, ,all oxygen is being used, and the remains is a inert gas. This process takes place in a 7 meter long combustion tube. The tube is cooled by water. The heated water is injected at the end of the cooling tube, and consequently the water will be turned into water vapor and steam. In other words, the Steamexfire produces an inert steam and water vapor. The system produces up to 25 cubic meters of inert product per second. The fore runner of the Steamexfire is called the GAG unit.

Underground mine fires
The Steamexfire has been deployed to kill underground mine fires at the Goedehoop mine fire in South Africa and at the Svea Nord mine fire on Spitsbergen Island. In mean time the Steamexfire system is one of the most important methods for suppressing mine fires globally.
