With a handle on the general design of a breaker, I then needed to see what capacity I needed for my Coke Oven Bank.
In ‘Real Life’ coke oven banks were very large. Banks of 50 or 100 ovens .. with multiple banks were common. Operations having 500 ovens evidently were used to supply coke to steel mills. My little operation of 16 ovens is therefore .. ‘quaint’. My explanation is that they supply coke for local foundries.
Each oven took a charge of between 4-6 tons of coal. My ovens are selectively compressed in width .. even with the width 3/4 the length the 16 ovens still take up 41-in modeled in O scale. Since I used selective compression I made a WAG that each charge would be 4 tons for my ovens – but let’s bump that up to an intermediate 5-tons just for grins. A coking operation runs on a 48-hour cycle. An oven is charged at 12-noon on Monday and the coke is pulled at 12-noon on Wednesday (more or less). What this means is that half the ovens are charged each day. 5-tons x 8 ovens = 40 tons a day required. Let’s further say that to be on the safe side we double that to 80-tons per day.
The chart on the left is one I mentioned earlier showing roll size with capacity. From that we can see very quickly that our 80-tons per day requirement could be satisfied very easily by the smallest rolls shows – the 15-in dia x 20-in long roll which had a capacity of approximately 10-tons per hour. That means even the smallest roll could meet our 80-ton per day requirement in just 8 hours.
