摘要
煤气化工艺是生产合成气产品的主要途径之一,因而煤气化装置合理的仪表选型,关系到整个煤化工装置能否长期、有效和稳定地运行。煤气化工艺的关键在于气化工段,由于其高温、高压、纯氧以及富含颗粒高磨损等特点,成为仪表选型的重点和难点。气化工段的氧阀、锁渣阀、黑水阀、合成气放空阀、煤浆流量测量仪表以及高温热偶更是仪表选型的重中之重,也是煤化工装置中仪表选型的核心关注点。
Since coal gasification process is one of the main ways for the production of synthesis gas product, the reasonable selection of instrument in the coal gasification device decides whether the whole coal chemical device can operate longtermed, effectively and stable or not.The key technology of coal gasification is the gasification section, because the characteristics of high temperature, high pressure, pure oxygen and rich in grain abrasion, it becomes the key and difficult points in the selection of instruments. The selection of a appropriate oxygen valve, lock hopper valve, blackwater synthesis gas vent valve, slurry flow measuring instrument and the high temper aturethermal couple in gasification selection is not only the vital important part, but the core concerns in the instrument selection of coal chemical industry as well.
