The invention discloses a blue brick firing method. The blue brick firing method disclosed by the invention is implemented through slurrying, pulverizing and compacting raw materials so as to obtain green bodies, feeding the green bodies into a kiln to fire, and in the kiln, sequentially preheating, firing, quenching, coloring and slowly cooling the green bodies, so that finished blue brick products are obtained. In the blue brick firing method disclosed by the invention, in the process of firing, heating is performed by using fuel gas, so that the firing temperature can be conveniently controlled; in the process of coloring, reduction is performed by using mixed reducing colored fuel gas, and a coloring burner is provided with a coloring valve, so that the supply amount of the colored fuel gas is conveniently adjusted, thereby accurately controlling the color of finished blue brick products; after the fuel gas is adopted for firing and reduction, the energy utilization rate is improved, and the pollution emission is greatly reduced; in the process of firing, preheated air subjected to quenching or slow cooling is used, so that the energy consumption is reduced; and the fuel gas reduced in the process of coloring, after being collected by a collecting tank, returns to the process of firing, so that the fuel gas utilization rate is further improved.
