Description
Intro
this powerplant respect the following requirements :
- It is a stackable design.
- It has no inputs (except water).
- It is fail safe (you will never have to fix it).
- It should be as compact as possible.
- It's almost red science only. For earlier construction you may feed the boiler with charcoal.
- It has to maximize the tiers 1 belt capacity (7.5 item/s)
Fail safe system
In order to make the powerplant completely fale safe I splitted the steam engine into to different grid.
- 4 of them are isolated from the main grid and an overflow valve ensure that steam is send to those first.
- the others are part of the main grid.
If you run the numbers you'll see that my design requires 7 steam engine mk2
In theory 3 should be enough to provide the 4.7 MW required (when ignoring the inserters).
In reality the electricity need may spike a little bit over 5.4 MW when running at full capacity. The mean consumption at full capacity is 5.1MW.
This explain why there is a 4th one.
Power generation
This powerplant produces 11.2 MW at full capacity (consumption of a cellulose tiers 1 full belt).
This will let you enjoy 6.1 MW for your factory at the cost of single water pump.
