The utility model discloses an energy-saving stable coal gas preheating device which comprises a detection mechanism, a controller, a supporting mechanism and a damping mechanism, the detection mechanism comprises a filter cartridge, two filter plates welded to the inner wall of one side of the filter cartridge, a first gas sensor installed on the inner wall of one side of the filter cartridge, a control valve connected to the top of the filter cartridge through a pipeline, a protection cylinder installed outside the control valve and a second gas sensor installed on the inner wall of one side of the protection cylinder. The first gas sensor and the second gas sensor are connected to the input end of the controller through signal lines. By automatically controlling the on-off of the gas preheater, the energy-saving effect is achieved to a certain extent, the protection barrel is arranged outside the control valve, when leakage occurs to the control valve, preliminary blocking can be conducted through the prot
