Description of the Related Art Various technologies have been actively developed today with respect to effective use of waste heat, combustion control, recycling, energy cascade, and the like from the viewpoints of energy saving, CO 2 reduction, environmental conservation, and the like. At present, various technologies such as supercritical boiler, combined cycle, cogeneration, etc. have been put into practical use, but in order to achieve greenhouse gas (CO 2 etc.) reduction targets, we will actively switch to various types of energy in the future. It is necessary to move forward.

It is difficult to recover and use energy due to low energy density, conversion efficiency, and stability, and high cost due to the inability to exhibit the economics of the equipment.

が必要になるという問題がある。[0005] A fuel reforming method that has been put into practical use is a method of obtaining a reformed gas by a water gasification reaction of a petroleum fuel. This method requires a lot of heating energy, and if this heating is performed by burning fuel, the inevitable mixing of CO 2 into the reformed gas is inevitable. However, there is a problem that purification of the reformed gas is required.

In the Texaco method, coal is pulverized to 0.1 mm or less, water is added to form a slurry, oxygen is blown from the top of the reaction tower, and light oil or natural gas or the like is burned as a fuel to lower the coal temperature to 14 mm.
It is gasified by heating to 00 ° C. or higher. However, also in this method, there is a problem that the reformed gas needs to be purified in order to use the reformed gas because CO 2 generated by combustion of the fuel is mixed into the reformed gas.
