Abstract

The present disclosure relates to an automatic control type hot smoke testing system which includes a fire source system, a smoke generation system and a control system. The fire source system is used for generating fire source and includes a first tank and several liquid fuel atomizing jet burners, wherein the first tank includes an air tank which is used for providing air and a fuel control tank which is used for controlling valves, distributing fuel and inspecting flame of the burners. The smoke generation system is used for generating smoke and includes a second tank, a smoke outlet pipe, smoke cake clamps and smoke cake turntables. Smoke cakes are initially placed in the smoke cake clamps, then moved to an ignition position one by one by for ignition, and finally rotated to through hole positions of a smoke generation box to fall into the smoke generation box by the servo motor. The control system is used for controlling the fire source system and the smoking generation system. The present disclosure overcomes the defects of the traditional manual hot smoke test, and realizes the accurate control of the smoke generation speed, the fire source power and the burning time, which …
