*2.3.4 Industrial application of fuel gas produced by Lurgi gasification with anthracite as raw material*

Shahe city is the capital of flat glass in China, where production capacity of flat glass accounts for about 20% of the total production capacity in China and a lot amount of industrial fuel gas is consumed yearly. Currently, the production mode of industrial fuel gas in Shahe city basically is shown as follows: each company has its own production device of industrial fuel gas, which produces hot coal gas with calorific value of about 1500 kcal/Nm3 by taking two-stage coal gasifier with lowrank coal as raw material. This production mode will induce serious environmental pollution for technical defects and scattered allocation. Under the background of

Through investigation and demonstration, Zemag Slagging Gasification (BGL) technology and Lurgi gasification technology with Shenfu coal as raw material are rejected and Lurgi gasification technology with anthracite as raw material is applied in Shahe project, which validates the technical and economic feasibility of producing industrial fuel gas by Lurgi gasification with anthracite as raw material.
