초록 ▼

Fuels are gasified in a fluidized state by a treatment with oxygen-containing gas and water vapor in a gasifying reactor. A solids mixture which contains ash and fine-grained fuels is combusted in a heating-up phase, which precedes the gasification and in which the temperature in the reactor is increased approximately to the temperature desired for the gasification. In a succeeding inertizing phase the supply rate of oxygen-containing gas is decreased and an inert gas is fed to the reactor until the product gas no longer contains free oxygen whereas the temperature is maintained virtually constant. In the succeeding gasification the fuel supply rate is increased and, after an adjusting time, the temperature is maintained virtually constant at the value desired for the gasification in the range from 600°to 1500°C. The gasification temperature is controlled by a change of the fuel supply rate.

대표청구항 ▼

A process of controlling the starting up of the gasification of fine-grained solid fuels, which are treated in a fluidized state with oxygen-containing gas and water vapor in a gasifying reactor, which is provided at its top end with a duct for discharging product gas and at its bottom portion with means for withdrawing ash, which comprises (a) during a heating-up phase preceding the gasification combusting a mixture of solids comprising ash and fine-grained fuels in a fluidized state in the reactor with a supply of oxygen-containing gas to provide a hyperstoichiometric supply of oxygen, thereby increasing the temperature in the reactor approximately to the temperature desired for the gasification, (b) immediately succeeding the heating-up phase by an inertizing phase, in which the supply rate of oxygen-containing gas is decreased and an inert gas is supplied to the reactor and the content of free oxygen in the product gas is decreased virtually to zero whereas the temperature is maintained virtually constant, and (c) succeeding the inertizing phase by the gasification, in which oxygen or oxygen-containing gas are fed to the reactor with or without steam, the fuel supply rate is increased and the temperature desired for the gasification, which when measured in the top portion of the reactor or in the discharge duct lies in the range from 600°to 1500°C., is maintained virtually constant after a time for temperature adjustment, and in which the supply rate of solid fuel is decreased when the temperature is too low and the supply rate of fuel is increased when the temperature is too high.
