Abstract
A kitchen hood assembly includes a combination hood cleaning and fire suppression system. The hood assembly includes a hood structure and a riser connected thereto. An exhaust blower forces an exhaust stream of air into the hood and through the riser. A combination hood cleaning and fire suppression system is incorporated into the hood structure. The combination hood cleaning and fire suppression system includes an elongated spray bar that is connected to a water source and includes a surfactant injector that injects a surfactant into the water being directed to the spray bar. In one mode of operation, the spray bar is effective to clean the hood assembly. In another mode of operation, when a fire is sensed in or in the vicinity of the hood, the same spray bar is utilized to inject an aqueous liquid into the hood to suppress the fire.
