Seeking advice from experts: The industrial park requires 750,000 cubic meters of heated gas per hour; what type of furnace technology is most suitable?
Thread Content
I would like to ask experts: In a glass metallurgy industrial park, the demand for gas for heating is between 750,000 cubic meters and 1.5 million cubic meters per hour. What type of furnace technology would be most suitable? One that can ensure economic efficiency while also being as environmentally friendly and safe as possible. I’m an outsider in this field, so I sincerely seek advice from experts. Thank you! Natural gas is too expensive; we can’t afford to use it

If you don’t know which coal to use, tell us the location and we can help you choose the right one. Also, requirements such as the calorific value and cleanliness of syngas are important in selecting the type of furnace.
Thank you, zyu3001. The location is in eastern Hunan, and there are no specific requirements regarding coal usage; the goal is to find the most economical and environmentally friendly method for producing gas. I asked for advice!
Currently, water-coal slurry gasification is referred to as green coal chemical engineering, and it produces a large amount of gas.
Thank you, zhlfwxx. But which type of furnace should be chosen? Texaco? Ruchi? Or something else? What’s the total investment approximately?

What is the quality of this coal? Because coal quality directly affects the choice of gasification technology. Your gas demand is quite high, at 750,000 cubic meters per hour. For example: even in the case of a shell furnace (2000 t/d), 6 gasification furnaces need to be installed ； If it is four nozzles or Texaco, with a coal feeding rate of 1,000 tons per day per unit, around 10 units would be required, I guess. In other words, your daily coal demand is between 12,000 and 24,000 tons (rough estimate); first of all, you need to ensure a stable supply of coal. Based on the quality of the coal to ensure a stable supply, the appropriate gasification technology is then selected. The total investment also needs to be preliminarily estimated based on the gasification technology you choose. And it’s not possible to simply choose the gasification technology and total investment based on the hourly gas demand you provide.
Check if there are coking plants around you Buy their coke oven exhaust gas and use it; I think it won’t cost much, and it will also help achieve energy conservation and environmental protection
750,000 cubic meters – what should be the calorific value of the gas? Or what is the heat amount? As a fuel gas, cost-effectiveness and environmental protection should be the primary considerations. The gasification intensity index of carbon molecule gasification technology is 1000 kg/m2•h; it can gasify various types of coal, and the cost of gas production is lower than that of fluidized bed, pneumatic bed, and Ruhr pressure furnace systems. We can discuss the details.
Thank you to all the experts for their responses. We haven’t given much thought to which type of coal to use; it would be best to use coal from Hunan locally or from Jiangxi in the vicinity. The calorific value of the gas produced is not required to be very high (anything above 1300 kcal/cubic meter will suffice). Since some existing companies use water-coal slurry or two-stage furnaces for gas production, which results in significant pollution, we hope to find a more economical and environmentally friendly coal-to-gas technology as a substitute. As far as I know, there are not many proven solutions available; the ones that exist include Shell, Texaco, Luqi, etc., with investment amounts of over 1 billion each. I’m not sure if there are any more cost-effective options. Special thanks to senc_lif /NEMO; the approach is worth considering.
I’m sorry; I realized just now that I didn’t explain it clearly at the beginning. The demand for coal-based gas is 750,000 cubic meters per hour. This amount is calculated based on the gas produced by two-stage furnaces, with an energy content of 1,500 kcal per cubic meter. If a different production process is used, the volume required per hour will likely not be 750,000 cubic meters. It needs to be converted based on the calorific value of gas
