Abstract

The invention discloses an entrained flow gasifier and a slag hole brick of the entrained flow gasifier, which are used for a gasifier. The gasifier comprises a combustion chamber and a quench chamber below the combustion chamber, wherein the bottom of combustion chamber is provided a slag hole; and the quench chamber is internally provided by a quench ring below the slag hole and a downcomer below the quench ring. The slag hole brick comprises an annular slag hole part and a cylindrical slag hole part, wherein the annular slag hole part is supported on a cone bottom plate of the entrained flow gasifier, and the cylindrical slag hole part is matched with the inner side of the quench ring below the cone bottom plate; the annular slag hole part extends outwards along the radial direction from the upper end of the cylindrical slag hole part. According to the slag hole brick of the gasifier disclosed by the invention, the quench ring is protected when the slag hole is formed, thereby the service life of the quench ring and the downcomer can be prolonged, the operational cycle of the gasifier is prolonged and the long-term operational efficiency of the gasifier is improved.

Description

technical field [0001] The invention relates to the field of coal gasification, in particular to an entrained-flow gasification furnace and a slag mouth brick. Background technique [0002] Coal is an important energy source. For a long time, the use of coal has been accompanied by serious environmental pollution. In recent years, people pay more and more attention to the clean coal technology aimed at reducing pollution discharge and improving utilization efficiency. Coal gasification technology, as one of the coal processing and conversion technologies, is considered to be one of the most efficient and clean clean coal technologies. [0003] Modern coal gasification technology, especially high-pressure, large-capacity entrained-bed gasification technology has been widely used in industry. In our country, many manufacturers have introduced and used modern entrained bed gasification technology. Modern entrained bed gasification technology is mainly divided into coal water ...
