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.

A steam generation system includes a water inlet pipe, an electromagnetic valve, a water pump, and a steam generator. The water inlet pipe is configured to convey liquid to the steam generator. The electromagnetic valve and the water pump are connected to the water inlet pipe, with the water pump providing power to drive the liquid through the water inlet pipe into the steam generator. The electromagnetic valve frequently opens and closes during operation, thereby creating a pulsed water flow into the steam generator. The steam generation system provided in this application can produce steam continuously and stably, with fast steam generation speed and controllable temperature, capable of producing high-temperature dry steam. The steam apparatus provided includes the aforementioned steam generation system.
