PURPOSE: A device and a method for pressurizing pulverized coal injection hopper are provided to operate in a stable injection process and reduce the use of nitrogen. CONSTITUTION: A device for pressurizing pulverized coal injection hopper comprises first ~ fourth injection hoppers(10,20,30,40), first ~ fourth pressure sides(11,21,31,41), first ~ fourth pressure detector(12,22,32,42), first ~ fourth pressure input unit(101,102,103,104), an injection controller(16), first ~ fourth pressure setting unit(14,24,34,44), first ~ fourth pressure controller(13,23,33,43), first ~ fourth pressure mode convertor(105,106,107,108), first ~ fourth back pressure side(15,25,35,45), a weight detector(17), and a nitrogen compressor(50). The injection controller and the weight detector are connected to the second ~ fourth injection hoppers through the same method with the first injection hopper.
