Calorie calculation
Thread Content
Currently, 1,500 tons of gasification slag are produced per day, with a heat content of 3,000 kcal； There is 500 tons of fine powder with a calorific value of 1,000 kcal. I would like to reuse these gasification residues through a circulating fluidized bed. How much high-pressure gas can be generated upon the combustion of this fuel? I’m new to the waste heat recovery industry; I hope experts can give me some guidance! Thank you so much!
You should find an expert to come up with a plan for you. Do experts not eat? Can’t everything be done for free then?
Huh? I’m seeking guidance; I can take you out for food or send you a red envelope via private message. I’m at the learning stage and just want to solve this problem. Thank you!
It’s simple knowledge; with the guidance of experts, if you want to turn this into a real project, I suggest you approach a specialized energy-saving design company to develop a plan, so that you can learn more. Haha, I’m not some expert either; I can’t eat
For this, you can go straight to the boiler manufacturer and provide them with these parameters; they can then offer you a simple recommendation for a suitable model. As for the steam parameters you need, the heat that can be generated can be calculated based on the enthalpy value of the fuel. By taking into account the thermal efficiency of the boiler, the heat content of the steam can be determined. The enthalpy value of the steam can be obtained from its parameters, which in turn allows for an approximate calculation of the amount of steam required. That’s roughly how it works
I have already replied in another topic post. I would like to ask what type of technology is used in gasification furnaces? Can the calorific value of the coarse slag be this high? A pulverized coal gasifier definitely won’t be this tall! .....
Project 1 offers many free cloud computing tools that can be used without cost!
This slag is produced by a fertilizer plant, using a fixed-bed batch gasification furnace. .
Such a large amount of slag! ! The daily coal consumption must also be very high, right? ? I’ve sent it to you via QQ and WeChat; feel free to communicate. Layered combustion furnaces such as intermittent gas generators and single-stage gas generators are all considered obsolete equipment, and many areas in China have successively imposed restrictions on their use or set deadlines for phasing them out. Is the amount of ash and residue so high? It is extremely uneconomical for a company to do so! Even when using briquettes, it’s still too high. Even if production is to be maintained for some time to come, I think there are many areas for improvement. Raw material control, minor equipment modifications, standardized operations... I suggest you verify the data (I suspect there are distortions in the data you provided); many nitrogen fertilizer plants have undergone upgrades and renovations. If this company has a promising future, considering the use of third-party contract energy services for technological upgrades could be an option. The Haichuan Forum contains a lot of information on intermittent gas generation and pulverized coal gasification; there is also a dedicated \"Gasification Technology Exchange Area,\" which you are advised to visit regularly when you have time.
