Selection of 1.2 million tons coke ovens: detailed specifications for TJL5550D type coke ovens
Thread Content
As the title indicates, I need values for parameters such as the turnaround time of this coke oven, the effective coal height, and the conversion rate of dry coal to coke. Thank you. Additionally, is it appropriate to use this type of coke oven in the design of a 1.2 million-ton coke oven? I estimate that a furnace array of 2×50 cells would be sufficient. However, when searching on the forum, I found that the answer given by the moderators was a 5.5-meter coke oven with 2×60 cells. I also came across information regarding the Shizong coal coking project, where it was stated that 2×50 cells were used for a capacity of 1.2 million tons; yet once the facility was built, its capacity turned out to be only 980,000 tons. I’m confused. Could any expert in coking give some explanation? Thank you. This post was last edited by lujianfei79 on 2009-4-8 at 10:36
It is advisable to apply for approval; projects exceeding 1 million tons need to be approved by the **Development and Reform Commission**. Approval from the provincial development and reform commission is sufficient for amounts under 1 million. Last edited by goudan020 on 2009-4-8 16:36.]
5.5m rammed coke ovens, with a turnaround time of 22 hours per oven; the annual production capacity per oven is generally estimated to be 10,000 tons. According to the entry requirements for coking projects in 2009, the total production capacity had to be greater than 1 million tons, using either 5.5m rammed coke ovens or 6m top-loaded ovens
The normal production capacity of a 2×50-hole 5.5m rammed coke oven is approximately 1 million tons per year, while that of another such oven is around 1.2 million tons per year; this varies to some extent depending on the compacting density of the coal pellets.
The production capacity of one furnace is approximately 10,000 tons; in my calculations I have certainly taken into account the effective length of such a coke oven. The effective width and similar values are incorrect (use the total length instead). Ignore the total height.) Does anyone have detailed data on this coke oven?
Total length of the carbonization chamber: 15,980 mm. Total height of the carbonization chamber (in cold state): 5,550 mm. Average width of the carbonization chamber (in cold state): 554 mm. Taper of the carbonization chamber: 20 mm. Center distance between the chambers: 1,350 mm. Coking time: 25.5 hours. Number of holes in the carbonization chamber: 2×60 holes. Moisture content of the coal fed into the furnace: 10%
The production capacity of a 5.5-meter ramming coke oven can be calculated using the following data; to achieve a capacity of 1.2 million tons, 2×60 chambers are required. The main structural dimensions are as follows: Total length of the carbonization chamber: 15,980 mm; Effective length of the carbonization chamber: 15,140 mm; Total height of the carbonization chamber: 5,505 mm; Effective height of the carbonization chamber: 5,200 mm; Average width of the carbonization chamber: 500 mm; Center distance between carbonization chambers: 1,350 mm; Taper of the carbonization chamber: 20 mm; Center distance between vertical flues: 480 mm; Number of vertical flues: 32; Wall thickness of the combustion chamber: 100 mm. The main technical parameters of the coking process are as follows: Size of the coal briquettes (length×width×height): (15,100/14,900)×450×5,200 mm; Density of coal briquettes (dry coal): 1.0 t/m3; Amount of dry coal that can be loaded into the carbonization chamber at one time: 35.1 t; Coking efficiency: 75%; Turnaround time of the coke oven: 22.5 hours
