Has the Luchihot furnace been phased out?
Thread Content
In accordance with the \"Notice of the National Development and Reform Commission on Strengthening the Management of Coal Chemical Industry Project Construction to Promote the Healthy Development of the Industry\" (Document No. Fa Gai Gong Ye 1350), it is prohibited to approve or register coke production projects and calcium carbide production projects that do not meet the industry entry requirements, as well as coal gasification projects that utilize fixed-bed batch gasification and direct-current cooling technologies. All consumption indicators for coal chemical projects must meet the **(industry) standards or mandatory regulatory requirements. I would like to ask whether gas production using Luchi furnaces falls under the prohibited categories?
Gas production using pressurized Ruhlig boilers with pulverized coal is not subject to restrictions
Luchi coal pulverization pressurized gasification is being used so effectively in our country! It also saves a lot on patent fees; it’s likely a mature and reliable technology, so it’s impossible to phase it out at this stage.
What to use for elimination? Those gas plants can close down
The Ruchi furnace uses pressurized vaporization and is of continuous fixed-bed type, so it does not fall into the categories mentioned above.
The Luchi furnace has advantages in urban gas supply
What is the consumption of Luchi furnaces like?
The new projects launched in these past two years, such as Lu’an, Xinjiang Guanghui, Datang, and Guodian, all use Luchi furnaces. Each type of furnace has its own advantages, and no single furnace type can cover everything
It’s not restricted at all! :lol
The gas produced by the Luchi furnace has a high calorific value and a high CH4 content, giving it advantages in coal-to-natural gas production
**Document No. 1350 does not specify any requirements for the gasification process. The Ruchi furnace is a type of continuous fixed-bed pressurized gasification process. Its use depends on the downstream product: it is relatively unsuitable for producing syngas, as it requires lump coal and has high requirements regarding the type of coal used. However, it does have advantages when used to produce city gas.
The fourth-generation pressurized Rucchi gasifier can have a diameter of up to 5 meters, with a raw gas production capacity of 75,000 Nm3/h (dry gas) per unit； Liquid slag discharge furnaces are also furnace types with significant competitive advantages. The new internal component design can accommodate a wider range of coal types, enabling large-scale industrial production.
The Luzzi furnace can be used for gas production as well; when used for ammonia synthesis, the coal consumption per ton of ammonia produced is around 1.3. It is possible to use low-quality coal and coal with low viscosity, and the efficiency is fairly good
I don’t quite agree with what the person on floor 11 said; the Luchi furnace is more adaptable to different coal qualities than the Texaco one. In particular, its ability to handle low-quality coal with high ash content is a great advantage. The Luchie furnace is not very suitable for bituminous coals with high viscosity
