Large Boiler

The Large Boiler is a Multiblock structure that burns enormous amounts of solid and liquid fuels to produce enormous amounts of Steam.

Crafting and Construction
A Large Boiler can be built from Bronze, Steel, Titanium or Tungstensteel. All versions Burn fuel at the same rate, but produce Steam at different rates.

The Large Boiler is constructed as a 3x3x5 Structure. The bottom Layer has the Controller in the middle front. Other parts of the bottom layer are:

1 or 2 Input Hatches to input Water. 1 or 2 Input Hatches/Buses to input Fuel. 1 Maintenance Hatch. 1 Muffler Hatch (Must face an Air Block). 3 or 4 Fireboxes.

The top 4 layers are made of rings of Bronze Plated Bricks/Solid Steel Machine Casings/Stable Titanium Casings/Robust Tugstensteel Casings (33 blocks total), with 3 Pipe Machine Casings in the center. Up to 9 of the Casings can be exchanged with Output Hatches, from which Steam is output.

A finished Large Bronze Boiler looks like this:



In the inside it looks like this:



Usage
Large Boilers must be filled with water at all times while active. If at any point the Boiler runs out of water, it will explode. Note: This is different from other boilers, and much more dangerous due to the Large Boiler's size.

The Boiler can burn all forms of solid and liquid fuel. Although it is less fuel efficient when burning refined fuels, the Boiler will heat faster while burning them. (For refined fuels, see the Diesel Generator.)

The Large Boiler takes time to heat up before it can produce steam at its maximum rate. Higher tier boilers take longer to reach maximum heat. Boiler heat affects its Steam output, but not its fuel consumption.

As with all other GregTech Multiblock Machines: Do NOT build a Multiblock over chunk borders. This can lead to unpredictable behavior. With NEI installed, chunk borders can be checked by pressing F9 (by default).

Before using the Large Boiler the first time it is recommended to do maintenance at the Maintenance Hatch.

To enable/disable a Boiler, hit it with a Soft Hammer.

Fuel Efficiency
Large Boilers produce Steam at tremendous rates, and consume fuel at appropriately similar rates. As a point of reference, Large Boilers consume 1 Charcoal every second.

'Steam Produced During Heating' figures apply to all Large Boiler fuels except for Diesel, Ethanol, and Nitro-Diesel (the Diesel Generator fuels).

The important thing to note from this chart is the Steam per Charcoal efficiency, notably of the Large Bronze Boiler, especially when compared to the High Pressure Coal Boiler.

Therefore, when compared with the High Pressure Coal Boiler, the Large Bronze Boiler:
 * Consumes fuel 160x as quickly
 * Produces Steam 53x as quickly
 * Has 67% lower fuel efficiency

The Large Boiler is an excellent way of producing large quantities of Steam with which to power a factory, but it cannot hold a candle to the High Pressure Coal Boiler if fuel consumption is a major concern.
