Expanded version of "Coal Slurry (Powder) Preparation" special post for soliciting opinions
Thread Content
This post was last edited by Jiang Chengzi at 2010-10-6 14:47 to expand the coal chemical industry zoning plan and add a "coal slurry (powder) preparation" section. It is planned to recruit 3 coal slurry preparation moderators and 1 to 3 technical staff. Hi friends who are familiar with or understand this aspect are invited to report. Posts can discuss the professional scope of this section, exchange and discussion content, etc. Good suggestions will be rewarded with 10 to 50 wealth, and those with bad suggestions will be punished with 10 to 50 wealth + deletion of posts. Please actively follow up! This post is not allowed to be rated by people below the version limit, thank you for your cooperation! ! The content of the post is as follows:: 1. The commenter is a moderator or technical staff member of the competition: Students in fifth grade and above are required to attach a personal introduction (a brief introduction to what you have studied, what you are engaged in, and what you are specialized in is enough). In addition, you need to express your thoughts on how to work in this section. 2. Posts by non-competitive moderators or technical staff: What are your opinions on adding this section? What is the professional scope and content of this forum?
I am currently engaged in coal chemical industry and am familiar with coal slurry preparation. I am willing to learn from you.* .
Coal slurry preparation should include pulverized coal and crushed coal, pressurized coal grinding and transportation
As for pulverized coal, there are currently many problems in the drying and transportation of pulverized coal, involving the measurement and adjustment of pulverized coal flow, the selection of drying technology, especially the pulverized coal drying problems encountered when using advanced pulverized coal gasification technology for lignite, and the problems of pulverized coal pumps currently being researched and designed. More can be exchanged and discussed. In addition, coal washing, coal quality optimization, etc. can be used as extended discussions. Generally speaking, coal slurry (powder) expansion is a good idea, but it should be noted that it should not be limited to the "preparation" point, otherwise it will overlap with gasification, but should involve the coal from the coal mine to the burner, which can also include special instruments, important valve equipment, etc.
I am engaged in Texaco coal-water slurry gasification, and I agree with the opinions above. I have only done a little research on coal-water slurry, and the moderator and technical staff were afraid that they would not be competent, so they expressed their opinions. Coal slurry is the source. High-concentration coal-water slurry has low oxygen consumption, high gas production rate, and high cold gas efficiency. We can study this aspect in depth. Secondly, we can discuss everything related to coal slurry, including equipment, instruments, electrical appliances, etc. In this way, the content of our new section will be richer.
I have been engaged in coal-water slurry gasification work for many years, but now I am working on a project and have very little time. Sometimes I cannot access the Internet for several days. I have been engaged in coal-water slurry pulping work for many years. I once published a paper on pulping in Nitrogen Fertilizer and Methanol Magazine, Issue 3, 2010. I'm interested in hiring a moderator, but I have too little time, which is a pity!
I am a beginner and not very familiar with this area, but I heard at a factory meeting that there is development in this area and I want to know more about it. I think this version can be divided into a few more parts, such as: Basic version, enhanced version, research version, difficult and complicated disease area. In order to increase the popularity, we have also taken measures to encourage more posts in the new version, but we should also note that the early posts will be more messy.

I am engaged in gasification operations and have enough time online every day. Let’s learn from each other in the future * , help each other, the sea is open to all rivers, and there is great potential. Practical actions are the best proof. ps cannot guarantee that Haiyou will have time to surf the Internet every day, and at the same time, the technology is relatively good, so he should be classified as a technician.
This post was last posted by Jiang Chengzi on 2010-10-7 16:44 Editor brother, the coal chemical industry is only responsible for the processing of coal after it enters the factory. The coal before entering the factory should belong to the coal mine or coal sales category.； In addition, there are special sections for instruments, etc., which are not suitable to be placed in the coal chemical industry division. The coal chemical industry division is basically a coal chemical industry technology exchange area, but its specialized equipment and instruments can be exchanged in the coal chemical industry division. The pulverized coal transportation you mentioned seems to be good at present using gas as a carrier.
Friendly support, I don’t understand. Are you also considering adding some equipment-related sections, for example, a section on refractory materials for gasifiers? :)
Actual before this version* The moderator "has walked on thousands of years of snow" is an expert in pulping, but unfortunately he is busy with official duties. The preparation area can also be expanded, such as the transportation of pulverized coal, the selection of additives and fluxes, the impact of coal blending on pulping, etc. Everything from coal preparation, preparing coal slurry and pulverized coal to transporting it to the burner can be discussed.
