What causes uneven production in Shift 3?
Thread Content
The coke output from the three shifts starts at the same time; the production volume of the morning and night shifts is roughly the same, while the difference for the afternoon shift can be over 1 ton. The process control remains the same; the same situation occurs after three shifts.
How is it possible that the numbers are the same? Is it 24 hours of coking? If the coking time is forced to be averaged across furnace numbers, the effect of volatile matter can be taken into consideration.
OP: Are you referring to the production volume of something?
1. Differences in operating conditions, such as temperature, coal feed rate, and load fluctuations； 2. Differences in employees’ capabilities, such as physical fitness, proficiency in their roles, optimization skills, and boiler operation techniques ； 3. Measurement differences, the start and end times of shift handovers, as well as the process of handing over boiler operation from one staff member to another.
The output is low; this is the case regardless of who is working the middle shift, among the three shifts. Previously, the shift supervisor specifically monitored the middle shift but was unable to identify the reason for it
Is the coal loading amount in the middle shift less than that in the other two shifts?
I really appreciate the answer from the 4th floor. I’ll guess: it’s due to the raw materials; after being exposed to the sun for a day, a lot of substances evaporate and are lost… It’s recommended to compare this with local weather conditions, such as whether it’s sunny or cloudy, hot or cold, and the wind strength……
I agree with the above view; regardless of who says it, the production volumes of the three batches differ, and the main reason for this is the different number of coke ovens, as well as the influence of temperature. Our factory management is personally involved in this matter, which is quite troublesome.
Analyze reasons such as the height of the coal cake
Support the view from the 4th floor; the original poster should rule them out one by one! !
When coal is loaded into the coke oven, gas is not produced in large quantities right away; there is a process involved. Those on the middle shift should observe the production process in the coke oven – the differences are quite subtle. It is recommended that the temperature of the washing oil (surface temperature) be reduced by 2 degrees compared to that during the day shift, and then check whether this setting works well. Remember, it’s the surface temperature that needs to be lowered by 2 degrees
