U-gas gasifier castable furnace construction material structure and construction method thereof

Abstract

The invention discloses a u-gas gasifier castable furnace construction material structure and a construction method thereof. The structure comprises a gasifier outer wall. The gasifier outer wall is connected to a fixed furnace construction material structure layer through a Y-shaped anchoring nail. The furnace wall is checked on the blowing down site and the operators on site carry out technicalcommunication so that the comprehensive reasons of the problem of the existing furnace wall are found, a corresponding furnace construction process is provided, the furnace wall reliability after repair is guaranteed, the existing furnace wall problems are solved, the furnace wall reliability in device operation is guaranteed, the long-term full-load safe operation of the u-gas gasifier is realized, urgent stopping caused by the furnace wall is avoided, the ordered operation is guaranteed and the core competitiveness of the company is increased.

Description

technical field [0001] The invention relates to a u-gas gasification furnace pouring material furnace building material and technology, in particular to a u-gas gasification furnace material structure and technology. Background technique [0002] With the development of society, especially the advancement of science and technology, it has greatly promoted the rapid development of social productivity, especially the wide application of some science and technology in industrialization, which has played a decisive role in boosting the qualitative development of the industry. [0003] u-gas gasification technology belongs to one-stage bubbling fluidized bed gasification technology. The raw coal reacts with steam and oxygen (or air, oxygen-enriched) in the bed of the gasification reactor to produce syngas, which is supplied to the downstream Synthetic chemical products or use as fuel. Its technological process is basically as follows: [0004] Raw coal needs to be crushed, drie...

AI Technical Summary

Problems solved by technology

[0005] Due to various reasons, the continuous working time of the u-gas gasifier is basically maintained at about 100 days. During each shutdown for maintenance, it is always found that the furnace wall is damaged or falls off, which will bring great hidden dangers to the next operation.

At the same time, during the operation of the equipment, there are always hot spots on the equipment. The temperature of the shell steel plate exceeds 350°C, and some even exceed 400°C, which brings safety hazards to normal production, and sometimes even directly affects the normal operation of the equipment. Cause emergency shutdown, resulting in greater economic losses
