I wonder if all of you’s coking plants have small coke ovens?
Thread Content
Given the large fluctuations in coal quality and intentional mixing of coals at present, does your plant frequently change its coal blending ratios? Are there small coke ovens? Is a small coke oven test conducted first for each ratio?
The coal blending ratio is generally determined based on the coal supply and production conditions.
Yes, there is. It is used for experiments. But it seems there is still a difference compared to large blast furnaces.
Small coke ovens are primarily used for testing – they serve as a means to conduct preliminary experiments when there are changes in the quality of the coal supplied or in the coal blending ratio, in order to collect important data. It is an essential “laboratory” for coking plants.
If there are no small coke ovens, iron boxes can be used for proportioning tests.
Operation method for iron box experiment ratio preparation； Create an iron box with dimensions of 300x450xless than the width of the carbonization chamber. Holes are drilled in all sides of the iron box except the bottom to facilitate heating. The upper wall of the iron box is equipped with an openable lid to facilitate coal loading and coke removal. Place the iron box filled with coal on the coke side of the carbonization chamber, as long as it does not obstruct the furnace door on that side. The iron box should be placed properly with some coke ash at the bottom. After securing the furnace door, production coal can be loaded. Once the coke in this furnace is mature, the coke and the iron box are pushed together into the coke quenching vehicle. After quenching the coke, place it on the cooling table and then locate the iron box. An iron box can only be used for one experiment. A ramming coke oven can also be used. Dig a hole 1 meter away on the defocus side at the top, bury the prepared coal cakes there, and then place them in the carbonization chamber.
Our factory has them; the coal blending ratio needs to be changed frequently – it’s impossible to avoid that
Where was this small coke oven designed and manufactured? For example, if schools also want to conduct experiments in this area, where can they find such small coke ovens?
Are there any particular things to keep in mind when conducting experiments using small metal boxes? We plan to do this soon, and I’m not quite sure
It doesn’t matter; the relevance is low. Wuhan University of Science and Technology and Anshan Iron and Coal Research Institute have them
By searching for \"40KG small coke oven\" on Baidu, many manufacturers can be found
