how many coal generators can i feed with 1 coal mine ...

With this you can feed up to 10 coal generators for 500 MW of power and have ~10 coal/min surplus. With those 10 coal/min you can run 11th coal generator underclocked at ~90% clock rate (additional 40-45 MW). So, the answer is: until you unlock the conveyor belt Mk.3 the maximum constant power output you can get from a single coal node is ~540 MW.

ratio of coal mines to steam engines - Factorio Forums

Nov 16, 2017· In .15, boilers consume 3.6MW of coal (to produce 1.8MW of steam which can feed exactly two steam engines). Given that a unit of coal has 8MJ energy, a boiler at full capacity requires 3.6/8=.45 coal per second or 27 coal per minute. A mine still produces .525 coal per second or 31.5 per minute. So, a fuel yellow belt of coal:
