Abstract

The invention provides a slagging device (2) for a fluidized bed gasification furnace, and further provides a slagging method for the fluidized bed gasification furnace. The slagging device (2) is provided with a bottom slag inlet (a) and a bottom slag outlet, and the slagging device (2) is configured to gasify and cool bottom slag (A). According to the slagging device and method for the fluidizedbed gasification furnace, smooth slagging of the fluidized bed gasification furnace can be ensured, potential safety hazards are reduced, energy conservation and consumption reduction are achieved, the carbon content of the bottom slag is reduced, and cold gas efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gasification, in particular to a slagging device and method for a fluidized bed gasification furnace. Background technique [0002] As an efficient and clean clean coal technology, gasification technology is the main way to convert solid primary energy such as coal into gaseous clean secondary energy. This technology is mainly used in chemical and metallurgical industries such as synthetic ammonia, synthetic methanol, hydrogen production, and blast furnace reduction ironmaking. , Combined cycle power generation and industrial and civil gas fields. [0003] Classified according to the state of movement of solid fuel, modern gasification processes mainly include fixed-bed gasification, entrained-bed gasification and fluidized-bed gasification. Fluidized bed gasification technology is one of the earliest industrialized gasification processes. The process is that the gasification agent with a certain pressur...
