A process with which a liquid fuel is evaporated completely in two stages is provided. In the first stage, the fuel is mixed with a hot primary medium and partly evaporated. In the second stage, the already evaporated fuel fraction is partly oxidized, which provides the heat for the complete evaporation of the fuel fractions which are yet to be evaporated. A fuel-air mixture for a reformer can be obtained with an advantageous embodiment of the process, in which the fuel is mixed homogeneously with oxidizing agent in the inventive evaporation. For the performance of the process, a mixing chamber is provided.

Process for evaporating a liquid fuel and a mixing chamber for performing this process

Liquid fuel is evaporated and mixed with an oxidizing agent in a mixing chamber of a reformer by first introducing substantially only the liquid fuel in an axial downstream direction into a first upstream zone of the mixing chamber via a nozzle so as to atomize the liquid fuel. Then steam is separately introduced into the upstream zone and contacted with the atomized fuel to cause the fuel to evaporate. An oxidizing agent is then introduced downstream of the first zone in a second zone of the mixing chamber to the evaporated fuel and uniformly mixing the oxidizing agent with the evaporated fuel.
