Abstract
An apparatus for cooling a gas distribution grid of fluidized bed gasifier and a method is provided in the present invention. The apparatus comprises a gas flow failure event detector for detecting a gasifying gas flow failure event, a flow control device for controlling the introduction of a flow stream of a liquid material into a spraying device placed in the plenum space of the gasifier, wherein the gas flow failure event detector is in signal connection with the flow control device, and a spraying device for spraying into the plenum space the liquid material as mist which evaporates and generates a positive pressure to cause through the gas distribution grid a flow which prevents the hot bed material from settling on the gas distribution grid.
