Comparison of coal gasification technologies

There are various opinions regarding pulverized coal, water-coal, water wall, refractory bricks, waste boilers, and lower-level cooling systems – some positive and some negative. Are there any authoritative documents available? These should consider factors such as actual operating scale, economic efficiency, stability, adaptability, safety, and maintenance. . . . . . . . . . . . .
The Modern Coal Chemical Engineering Technology Manual, coal gasification technology, as well as the books written by Professor Tang Hongqing all cover these topics, but they can only be used as references; what’s most important is to consider one’s own raw materials, products, and available funds in RMB
Different industries, different types of coal, and varying product requirements correspond to different gasification technologies. There is no best, only what suits.
What the friend upstairs said is right – there is no best option, only what suits one’s needs. For example, the wastewater from Lurgi furnaces is difficult to treat, but the gas produced contains a high level of methane, making it suitable for coal-to-natural gas production.
Different industries, different types of coal, and different product requirements correspond to different gasification technologies. There is no best, only what suits. It should also be mentioned here that the nature of the enterprise, as well as the personal intentions of the investment decision-makers, are very important factors that influence the choice of specific gasification technologies.
Have any users used a space furnace or a Shenning furnace?
Once this product has been selected, you just need to compare options and determine the best combination of investment and operational costs that suits your current raw material situation (this \"best\" option is determined by comparing the entire hydrogen production process, including air separation)
There are quite a number of projects operating using space-based gasification technology. Among those operated by Shenning, only the Shenhua Ningmei Olefins and coal-to-oil projects use this technology. The best example is the Ningxia Kunpeng project, which utilizes their 3000 t/h system; our project, on the other hand, uses space-based gasification technology, with ethanol as the target product
After selecting one or several potential coal gasification technologies, it is also necessary to obtain samples of one or several possible feed coals for the future plant and test them in the corresponding gasifiers, in order to identify the most economical and suitable coal gasification technology.
