Among the gas generation furnaces such as GSP, HT-L, and East China four-nozzle type, which one has a high consumption?
Thread Content
Between the GSP and HT-L gas generation furnaces, which one has higher consumption? Generally speaking, these two types of gas generation furnaces are suitable for development. I was wondering if any fellow sailors who have experienced them could share some information? Our company has a new project and would like to refer to this. Additionally, how does the four-nozzle furnace at East China University of Science and Technology compare to it? In China, for processes such as coal-to-oil, olefins, and ethylene glycol, which type of furnace is the best choice?
Let’s start with the types of coal. As far as I know, space furnaces currently use mostly anthracite; other types of coal have not been used on a large scale for long periods of time. I’m not very familiar with GSP – I only know that it can handle coal with high ash content and high ash fusion points, such as the Huainan coal. The coal used in four-nozzle systems requires a lower ash fusion point. Well, I think it’s better to ask experts in gasification to provide an answer; let’s all pay close attention to this together
Collin Technology? {:3_62:} We use bituminous coal from Jincheng, which is a type of coal with a high ash fusion point; therefore, after consideration, we decided to use HT-L or GSP
The control of the four-burner process system is relatively complex; aerospace furnaces are already used for burning coal with high ash content and high ash fusion points over long periods of time
Has the space furnace been used to burn coal with high ash content and high ash fusion point over long periods of time? ? What is the overall situation of the space furnace’s operation at present?
Theoretically, GSP and HT-L belong to powder coal gasification, and their gasification principles are very similar. HUARI’s four-nozzle system belongs to water-coal slurry gasification. Consumption should be lower for GSP and HT-L. Powder coal gasification enables long-term stable operation; it has better adaptability to different types of coal, lower coal and oxygen consumption compared to water-coal slurry gasification, resulting in overall lower energy consumption, which gives it advantages for further development. It is recommended to consider HT-L; it has performed well in Linquan, Anhui over the past two years. It uses domestic technology, requires lower investment, offers faster service, and has been in operation in China for a longer period of time than GSP.
Well, I think so too. At present, space furnaces should be gradually becoming more mature. As for the specific technologies, we are working on them on our own, while foreign countries might have stopped making progress in this area. I need to take the opportunity to study in detail how space furnaces function
In fact, each type of gasifier is particularly suitable for a specific type of coal; therefore, when choosing a coal gasification technology, one should mainly consider the type of coal available. If possible, I still recommend choosing domestic technology – on one hand to support local industries, and on the other hand because it can be adjusted appropriately according to the quality of your coal to optimize its performance.
Of course that’s the case; space furnaces may not be suitable for coal types with temperatures over 1500 degrees. So what kind of furnace would be appropriate for such coal types? Also, what should be done regarding the gas used in the retrofit of old fixed-bed units? What if one day **the fixed-bed gas generation method is phased out? ? ?
Before deciding on which gasification technology to use, it is advisable to conduct slurry formation tests on the coal type first; it is possible that the coal’s slurry formation properties are poor, making it unsuitable for coal slurry gasification. After all, at present, both in China the GE technology and the four-nozzle water-coal slurry gasification method maintain a higher level of operational stability. Additionally, it is recommended to go directly to the factories where HT-L and GSP are in use for an on-site inspection, as they have not been in operation for long and maintain good confidentiality measures. Only by experiencing things firsthand can one determine which technology is more suitable. Additionally, while HT-L may not be able to conduct trial burns with different coal types, GSP can carry out such trials first.
