Which is the best coal powder fluidized bed gasifier for industrial use at present?
Choose a powder coal gasifier that suits your production process, taking into account factors such as the transportation of raw coal, the availability of coal, and whether the gasifier is environmentally friendly. There are many drawbacks to starting to use Endu furnaces, and it’s difficult to address them. It was later changed to natural gas.
Fluidized-bed gasification: KBR, U-gas, Endler furnace, KSY. The Chinese Academy of Sciences also has one, but it has not been used; I’m not sure which one is better. However, based on our criteria for selecting a gasification method, we take into account factors such as the properties of the raw materials, the characteristics of the products, financial considerations, safety and environmental requirements, as well as the maturity of the technology
It depends on what you do in your downstream operations; currently, the circulating fluidized bed technology developed by the Chinese Academy of Sciences in the field of engineering is quite good, and its performance is also satisfactory
To address the issues associated with fluidized-bed gasification or fluidized-bed pyrolytic gasification, such as low carbon conversion rates, low gasification efficiency, problems related to organic wastewater, and a high amount of fine particulates in the gas phase, we have developed a multi-bed clean and efficient pyrolytic gasification process that can be used for applications such as coal-to-natural gas production, fuel supply for glass furnaces, and metallurgical processes, among others. Zero discharge of organic wastewater is achieved while producing coal tar as a by-product. The pilot-scale process package has been completed. If interested, we can collaborate on development.
I remember them participating in several renovation projects for small nitrogen fertilizer fixed-bed gasification units
Yes, there is a pressurization demonstration project in Jinchang that has been in operation for half a year now. Other projects were put into use in Xinjiang and Guizhou during the first half of this year. The company has achieved significant success in the industrial gas sector, with over 70 units currently in operation.
I was wondering if the original poster could provide data on the operation of this type of furnace, its consumption metrics, and the investment required for it?
Your question is about problematic hashes. Briquette coal is used in fluidized bed gasifiers, huh! A circulating fluidized bed is not for pulverized coal; if it were used for pulverized coal, circulation would not be possible. The calorific value of the gas produced by circulating fluidized beds is relatively low. I’m not sure what products you produce in the subsequent processing stages; it would be fine if it’s low-calorific value gas. It’s not profitable to produce chemical products in small quantities. If you are referring to coal powder fluidized bed gasifiers, there are numerous options available: Shell, Texaco, Aerospace Furnace, Jinhua Furnace, and so on! When it comes to investment, Jinhua furnaces are a good choice!
The operation performance is satisfactory; the gasifier, when operated over long periods, has an average annual operating rate of around 300 days, with a maximum operating time of 527 days
The operation of the gasification furnace is satisfactory; furnaces that operate over long periods have an annual operating time of around 300 days, with the longest operating duration reaching 527 days. There are differences among various projects in terms of consumption and investment.
