Which foreign technology was used as a reference for the process technology of the space furnace? (Is it Texaco, Shell, Siemens...? ）

GSP’s combustion chamber + Texaco’s quench chamber = space furnace

Former Shell system shell (identical)

Shell technology + Texaco hybrid

The furnace chamber and water wall are modeled after Shell, while the burners and feeding methods are based on Texaco; in other words, it’s a combination of elements from various companies

Many of the pipelines inside need surfacing; otherwise, they are prone to corrosion by hydrogen sulfide

The coal conveying system belongs to Shell; the combustion chamber in the upper part of the gasifier is from GSP, while the lower part as well as the slag treatment system in the rear section are from Texaco

It’s borrowing there; it’s complete plagiarism and grafting. Combine furnaces of the same grade from different sources completely together. Just change the tag number. There is no own process package; only EPC is implemented, and in reality no own computing capacity exists (it seems to be just about selling combined drawings:@). If you’re capable, go ahead and develop your own 3,000-ton furnace. Nowadays, for 3,000-ton furnaces operating at 4.0 MPa, the powder feeding systems of shell type can be copied, but it’s no longer possible to copy the burners of GSP type (since GSP has been phased out by Shenning). GE offers quench chambers capable of handling 6.5 MPa, but those for 4.0 MPa seem not to exist yet (including systems for slag treatment); it’s therefore difficult to copy such technologies. Therefore, although a project of 3,000 tons has been approved, it is difficult to implement. 6.5MPa gasification is a major drawback of pulverized coal, so there’s no need to discuss it.

You have all 3 of those listed, isn’t that amazing;P
