干煤粉加压气流床气化试验研究

An Experimental Study of Dry Pulverized-coal Gasification in a Pressurized Airflow Bed

介绍了36t/d加压气流床气化中试装置主要设备、工艺流程及工艺条件的选择,并给出试验研究中多个煤种在气化压力3.0MPa、投干粉煤量1t/h条件下取得的主要试验数据。从试验数据看出,干法气化指标明显优于水煤浆气化,主要是CO2含量低,有效成分(CO+H2)含量高(均大于89%),证明了干煤粉气化的优越性。试验结果基本达到预期目的,积累了干粉煤气流床气化数据。

Described are the main equipment,process flow path and the selection of technological conditions for the gasification pilot plant of a 36 t/d pressurized airflow bed.Also given are the main test data obtained for a multitude of coal ranks undergone experimental research under the condition of the gasification pressure being 3.0 MPa and dry pulverized coal fed being 1 t/h.As can be seen from the test data,the indexes of dry-method gasification are obviously better than those of coal-slurry gasification,mainly due to a low CO2 content and a high content of effective constituents CO+H2 (both greater than 89%).The foregoing demonstrates the superiority of the dry pulverized coal gasification.The tests have basically achieved the anticipated aim and accumulated relevant data for dry pulverized coal gasification in an airflow bed.
