How often should a complete analysis of coal be done? When coal is used for gasification, it is difficult to ensure a stable supply of coal. Even if it is stable, the coal type may not necessarily meet the standards. If this happens for a long time, it will not be good for the life of the equipment, and in serious cases, it will affect production. For example, last time I went to Inner Mongolia Yitai to inspect and evaluate the use of the burner, it was said that the temperature around the furnace was different and there was a tendency for partial spray. However, it was also said that the coal supply had not been available recently, and the volatile content of the coal was 38%, and the ash content was 12%, exceeding * * Gasification coal standards. We are embarrassed. First of all, using coal is always inconsistent with * * requirements, and it does not meet the design requirements of the equipment. At the same time, we are required to repeatedly test and evaluate the equipment, which makes the nozzle use time short and affects the reputation of the nozzle company. It's never a solution. Is this the case in every factory? How much attention is paid to coal sources? .Note$#, $ $
According to personal understanding, 1. For coal gasification, the selection of gasifier is generally very important. Generally, gasifiers in chemical plants are selected according to the type of coal. So far, I have not heard of the so-called gasifier suitable for all types of coal. for * * I don’t quite understand the standards for coal used in gasification. There may be coal usage standards for power plants. 2. General coal gasification uses nearby coal resources. Due to the distribution of coal, coal from a certain place or several places is often used to ensure continuity of coal quality. These coals are used for a long time, and the coal quality should be stable. 3. In coal gasification, coal quality analysis is included in the normal raw material analysis, mostly once per shift. As for whether to do a full analysis, I'm not sure. When imported coal enters the factory, it should be fully analyzed, including industrial analysis and elemental analysis.
