Method and apparatus for a coal gasifier
View Patent ↗A method and apparatus for efficiently forming a gaseous material from a solid starting material. The produced gaseous material includes a CGE HHV having a high percentage of an original HHV of the starting material. The gaseous product may be used to form a plurality of materials for various purposes.
1. A gasification system comprising:
a high temperature gasifier for operating at a first temperature;
a low temperature gasifier for operating at a second temperature that is lower than the first temperature, the low temperature gasifier being located downstream from the high temperature gasifier; and
a cyclone separator connected between an outlet of the high temperature gasifier and an inlet of the low temperature gasifier.
2. The gasification system of claim 1 , wherein the first temperature of the high temperature gasifier includes a temperature range of at least 1200° C. and the second temperature of the low temperature gasifier includes a temperature range that is less than about 870° C.
3. The gasification system as recited in claim 1 , wherein the low temperature gasifier and the high temperature gasifier are each mounted directly to the cyclone separator.
4. The gasification system as recited in claim 1 , further including a heat exchanger that is fluidly connected with the low temperature gasifier.
5. The gasification system as recited in claim 4 , wherein the heat exchanger is fluidly connected with the high temperature gasifier.
6. The gasification system as recited in claim 5 , wherein the heat exchanger is fluidly connected with the cyclone separator.
7. The gasification system as recited in claim 1 , wherein the high temperature gasifier includes a first vessel and the low temperature gasifier includes a second, different vessel.
8. The gasification system as recited in claim 1 , wherein the high temperature gasifier and the low temperature gasifier include separate and distinct internal volumes.
9. A gasification system comprising:
a high temperature gasifier that includes a first vessel for operating at a first temperature;
a low temperature gasifier that includes a second, different vessel for operating at a second temperature that is lower than the first temperature, the low temperature gasifier being located downstream from the high temperature gasifier; and
a cyclone separator connected between the high temperature gasifier and the low temperature gasifier.
10. The gasification system of claim 9 , wherein the cyclone separator is connected between an outlet of the high temperature gasifier and an inlet of the low temperature gasifier.
