Abstract
A novel reformer is provided. A gas fuel is guided from a fuel channel. Air and water are guided from a liquid/gas channel. They are mixed together in a mixing space. On mixing them, the temperature of the mixing space is between 150° C. and 300° C. Thus, the reactants are preheated and fully mixed; and a proper temperature is reached to avoid local over-heating and to prevent carbon deposited.
Claims4
An anti-soot reformer, comprising
- a furnace;
- a channel unit located in said furnace and comprising:
- an elongate mixing space;
- a hollow tube fuel channel configured to convey fuel and extending from a front end of the mixing space through an interior of the mixing space and terminating within an opposite tail end of the mixing space;
- and
- a hollow tube liquid/gas channel configured to convey air and water and coiled around an outside of the mixing space from the front end to the tail end thereof and penetrating into the mixing space at the tail end of the mixing space without directly touching the mixing space and such that the mixing space is located between said fuel channel and said liquid/gas channel, wherein gaseous fuel, air, and water are mixed at the tail end of the mixing space at greater than 150° C. such that the mixed gaseous fuel, air, and water counterflows within the mixing space while increasing in temperature to exit the front end of the mixing space at lower than 300° C.;
- a temperature controller programmed to maintain a temperature higher than 150° C. and lower than 300° C. within the mixing space;
- and
- a reactor connected with said mixing space of said channel unit.
