[0040] Example 1-5
[0041] use figure 2 In the method described in the above, the lignite coal powder produced in Inner Mongolia that is dried and ground to a particle size of about 1mm is loaded into the coal powder silo, and the coal powder is directly perpendicular to the first flow path through the star discharge valve. The method is added to the combustion flue gas from the oil burner flowing at the temperature and superficial velocity described in the table below, without using any carrier gas to transport the pulverized coal. The first flow channel is a section of horizontal pipeline, made of 310S steel, lined with mullite refractory layer, the length of the first flow channel is 6 meters, and a high temperature cyclone separator is installed at the end of the pipeline to separate the semi-coke from the first gas product Separate and immediately analyze the volatile content in the semi-coke. The analysis method is based on GB / T212-2008. The results are also listed in Tab...
Example Embodiment
[0053] Example 6-8
[0054] use Figure 4 The gasification experiment shown by the first flow channel and the second flow channel in series is carried out in the gasification experiment, and the high temperature cyclone separator is installed at the end of the second flow channel, wherein the cross-sectional area of the second flow channel is the first flow channel The cross-sectional area is 25 times, and the experimental parameters are shown in Table 4. The second gas stream is oxygen, and the temperature after mixing with the first product stream is controlled at 800°C. The high-temperature cyclone separates the ash and the second gas product. The residual carbon content in the ash was measured, and it was found that it was basically less than 4%, indicating that the total carbon conversion rate could reach over 96%. Of course, if the length of the second flow channel is further extended or the feed amount of O2 is increased, the total carbon conversion rate will be furth...
