Abstract

Provided are a method for operating a gasifier, a gasifier, a two-stage gasification device, a method for gasifying an organic raw material, and a method for two-stage gasification of an organic waste, with which it is possible to stably operate the gasifier over a long period of time. A method for operating a gasification furnace includes directly or indirectly introducing an alkali metal-containing compound into the gasification furnace to reduce the viscosity of the slag in the gasification furnace into which an organic raw material is introduced to generate a gas and the slag.

Description

technical field [0001] The present disclosure relates to an operation method of a gasifier, a gasifier, a two-stage gasification device, a gasification method of organic raw materials, and a two-stage gasification method of organic waste, which can be applied to the gasification treatment of organic wastes such as waste plastics . Background technique [0002] In conventional gasifiers used for gasification treatment of organic wastes such as waste plastics, municipal waste, sewage sludge, waste FRP, biomass waste, automobile waste, waste oil, etc., in order to gasify the gas containing hydrogen and carbon monoxide The gas such as the gas is separated from the slag containing ash, and an incombustible substance separation chamber is provided below the combustion chamber of the gasifier. In order to suppress de novo synthesis of dioxins in the gasifier, a throat section having a smaller cross-sectional area than that of the combustion chamber is provided between the combusti...
