Gas production volume of coking ovens?
Thread Content
May I ask what the gas production rate per hour is for a coking oven with a capacity of 30,000 tons and one with a capacity of 50,000 tons? Thank you. We use Shenfu coal for burning. This post was last edited by ryn on 2009-2-18 10:05]
Based on the assumption that 330 cubic meters of gas are produced per ton of dry coal, the amount of dry coal used per unit of time can be calculated; multiplying this value by 330 gives an approximate estimate. For precise measurement, a flow meter needs to be installed
Is the tar content high in coke oven gas? Can a flow meter be installed?
Currently, with coal volatiles ranging from 25 to 32, the coking time varies, and as a result the gas yield also differs. A flow meter can be installed.
I am collecting relevant information, but considering coal prices and the varying volatility levels of coal, which range from 25% to 32%, the amount of gas produced will certainly differ; therefore, it’s not possible to use a single constant value for calculations.

It’s sufficient to calculate based on a maximum output of 350 cubic meters per ton of coal.
The gas production per ton of dry coal is around 15 percent
Hehe, professional books contain the calculation formulas; generally, an estimate is around 300-330 m3 per ton of dry coal.
All the algorithms mentioned above make sense; in fact, the type of coal plays a very important role. When coal is used for coking, the amount of bituminous coal used is the key factor determining the amount of gas produced. It also must be taken into account when calculating.
I’m not sure how precise the owner wants the figure to be, but as far as I know, no value of 350 M3 per floor has been reached yet. It would be helpful to know what type of furnace and what kind of coal is being used, as well as its quality, in order to determine whether such a volume can actually be achieved. I think 320 M3 should suffice; generally, coke ovens are designed with 320 M3 as a standard figure. However, this is only a rough estimate. If the owner wants an accurate figure, it’s best to install flow meters and calculate an average over a certain period of time.
The gas output per ton of coal is 320 cubic meters of gas; by combining this with your coal loading rate per hour, you can calculate the gas output per hour!
It depends on what you’re using the gas volume calculation for; if you need to estimate the gas purification equipment, it’s recommended to use the highest gas production rate. To calculate costs, a flow meter is needed. If calculation is required, it should be done based on the volatility of the coal blend; detailed corresponding values can be found in the \"Coking Design Reference Materials\".
It mainly depends on the volatiles content of the coal. Our plant is equipped with a flow meter, but it doesn’t work very well; the value is around 300–380
It has a lot to do with the ratio of mixed coal. Our factory is between 290 and 350
1 ton of dry coal produces 300-350 cubic meters of coke oven gas
30,000-ton and 50,000-ton furnaces? What kind of furnace is it? :o :o :o
2500~3000 cubic meters per hour
Based on the commonly used calculation method: theoretically, 320 m3 of gas can be produced per ton of coal. By determining your hourly coal loading rate, it is possible to calculate the hourly gas production volume. Of course, if very high precision of the data is required, then it is necessary to take into account the volatility of the blending coal; if the facility is already in operation or about to start operating, it is best to use meters for measurement.
Depending on the volatile content of the coaling coal, the amount of gas produced will certainly vary, as will the coking rate; therefore, if accurate calculations are required, a simple calculation using a constant is not feasible. For estimation purposes, an gas production volume of 320 m3 per ton of dry coal can be used, with a coking rate of 76%. The gas production volume for an annual output of 30,000 tons of coke is approximately 1,442 m3 per hour, while for an annual output of 50,000 tons of coke it is around 2,403 m3 per hour.
Related to the volatiles of coal and coke oven heating
May I ask, is this the total amount of gas or the remaining amount? What percentage does furnace gas account for?
