An object of the present invention is to provide an ammonia generating method and apparatus that can be operated continuously for a long period of time, and that reduces the cost. The present invention has a gasification furnace 2 into which coal and air are introduced, constituted to perform partial oxidation to gasify the coal; a desolfurizing apparatus 3 constituted to desulfurize the gas generated by the gasification furnace 2; a shift reactor 4 constituted to convert carbon monoxide present in the gas exhausted from the deselfurizing apparatus 3 to carbon dioxide; a carbon dioxide scrubber 5 constituted to remove carbon dioxide present in the gas exhausted from the shift reactor 4; a denitrification apparatus 6 constituted so that, by removing nitrogen present in the gas exhausted from the carbon dioxide scrubber 5, the molar ratio between nitrogen and hydrogen present in the gas is adjusted to approximately 1:3; and an ammonia generator 7 that generates ammonia by causing a reaction between the nitrogen and hydrogen present in the gas exhausted from the denitrification apparatus 6. |
