The utility model provides a staged combustion decomposing furnace which comprises a furnace body, a coal distribution cavity, a low-oxygen reduction cavity, a main combustion cavity and an SNCR (selective non-catalytic reduction) denitration reduction cavity are constructed in the furnace body, a coal inlet pipe communicated with the coal distribution cavity is fixedly mounted on the furnace body, and an exhaust pipe communicated with the SNCR denitration reduction cavity is fixedly mounted on the furnace body. By means of the design of the adjusting mechanism and the supporting blocks, when the third-level air pipe and the air inlet pipe are connected and fixed, the arc-shaped grooves in the ends of the two supporting blocks are attached to the third-level air pipe, the third-level air pipe is positioned, and therefore when the third-level air pipe and the air inlet pipe are connected and fixed, positioning of the third-level air pipe is facilitated; at the moment, the third-stage air pipe and the air inlet
