The invention discloses a simulated fire combustion firefighting system. The simulated fire combustion firefighting system comprises a control device, a smoke generation device, a warm wind generation device, a nozzle array device, a lamplight generation device, a sound effect generation device, a pipeline conveying device and an infrared receiving device. The control device is connected with the smoke generation device, the warm wind generation device, the lamplight generation device, the sound effect generation device, the pipeline conveying device and the infrared receiving device, and the pipeline conveying device is connected with the smoke generation device, the warm wind generation device and the nozzle array device. By the adoption of the mode, the simulated fire combustion firefighting system can represent scenes of real fires through sound, images and warm gas and enable people to comprehensively understand and know fire occurrence and fire extinguishing knowledge, and then firefighting indoor drilling can be conveniently developed.
