    摘要： A system can quickly cool and de-pressurize a boiler arrangement under non-normal operating conditions such as loss of plant power. A discharge system injects into the furnace a combined stream of steam from a steam discharge system and ambient air, thereby both cooling components of the boiler arrangement and reducing pressure in the steam/water circuit. This reduces or eliminates the additional cost associated with providing extra capacity in a steam drum and/or an independently powered boiler water pump. The system is particularly useful for quickly cooling the U-beams of a circulating fluidized bed boiler during a black plant condition.

    摘要： A valve system for use in conjunction with a hot water heater where the water line to the hot water heater passes through the valve system which, when a leak is detected by an electrical sensor, causes a motor to drive a gear which moves a gear rack laterally to pull a rod attached to a gate which gate moves over a valve outlet to block further flow of water to the hot water heater.
