The invention relates to an auxiliary power device exhaust pipe fireproof installation assembly and an airplane. The auxiliary power device exhaust pipe fireproof installation assembly is installed on a fireproof wall behind an APU cabin and comprises a connecting piece, a corrugated pipe, an APU exhaust pipe front supporting piece and an APU exhaust pipe. The connecting piece is used for sealing connection between the APU body exhaust ejector and the corrugated pipe, the corrugated pipe is connected between an outlet of the APU body exhaust ejector and the APU exhaust pipe front supporting piece, the APU exhaust pipe front supporting piece is used for being connected with the corrugated pipe, the APU exhaust pipe and the firewall, and the front end of the APU exhaust pipe is connected with the APU exhaust pipe front supporting piece. And the rear end is communicated with external atmosphere to exhaust high-temperature exhaust gas of the APU body. According to the technical scheme, the fireproof door has the advantages of being simple in layout, easy to install, light in overall weight and capable of meeting the fireproof requirement.
