Calculate the daily and nightly coal consumption of the coke oven

66 series coke ovens? Is a week 12 hours long? 50/12×3.94×24≈394 tons

The turnaround time mentioned by the original poster is indeed problematic; it should be 12 hours. The calculation method is as provided by the second poster. Let me explain it: one turnaround time corresponds to one small cycle, during which all 50 carbonization chambers – 2*25 chambers – produce coke once. With a turnaround time of 12 hours, two cycles occur in one day and night, that is, two small cycles. Each small cycle results in 50 batches of coke being produced, so two cycles yield a total of 100 batches. Each batch requires 3.94 tons of coal, so 100 batches require 394 tons of coal in total. Hence, the amount of coal used in one day and night is 394 tons, haha! It’s a bit wordy, but since the original poster is new to this topic, it’s better to explain things clearly. The key is to understand what turnover time means, and then the problem will be easily solved!

2*25*24*3.94/12=394 tons

Upstairs, the calculation is based on the turnaround time. As for my understanding, it is centered around the amount of coal that can be loaded into each carbonization chamber per hour. Each carbonization chamber receives 3.94 tons of coal per loading, and the coking time is 12 hours; therefore, 3.94/12 gives the average amount of coal that can be loaded into each chamber per hour. A furnace has 2*25 carbonization chambers, and there are 24 hours in a day, so the total amount of coal is 3.94/12*50*24 = 394 tons. I hope my explanation is clear.

2×25×3.94×24/12=394 tons; 24/12=2 indicates two turnover cycles per day and night

The turnaround time is 12 hours; this means that two batches can be produced per well per day. With 50 wells in total and 3.94 tons of coal per batch, the calculation is as follows: 2X50X3.94=394 tons.

2×25×3.94×24/12=394 tons

Everyone has said nice things, so I won’t add anything more. Now the original poster should understand!
