Burning Box (Solid)

GregTech 6 Burning boxes convert Furnace Fuel into Heat Energy.

The efficiency and rate depends on the material used on the sides of the recipe, which contains the Heat. The only 100% efficient box is Invar, but it has a low rate of 16 HU/t. Tungsten comes close with 95% with a higher 128 HU/t rate.

They come in normal and Dense varieties. The Dense ones cost about 4-5 times the material but also have a 4 times the output rate, without any change in efficiency compared to the normal ones. In order to make them you need a Dense Copper Plate, and therefore a way to compress them, meaning it is higher Tech.

At 100% efficiency one Furnace Smelting equals 5000 Heat Units, so Coal/Charcoal would be 40000 HU, Coal Coke 80000 HU and Alumentum 160000 HU for example, it also accepts Wooden things (7500 HU), Saplings (2500 HU) and all the other Furnace Fuels.

Many Fuel Materials have some kind of Ashes, which are left behind when burning them. These Ashes has to be removed regularly from the Burning Box in order for it to work. Coal Coke and Alumentum don't have those Ashes for example.

The Burning Box is very primitive, meaning it has no GUI and won't receive any GUI. Anything you insert for burning by rightclicking the front of the Box with it will get burnt without mercy (if it is a valid Fuel, and if you don't happen to wrench the Box right afterwards, and only when the Box is actually active).

In order to work, it also needs a Block without Collision Box in front of it (Air is such a Block without Collision Box).

It also emits its Energy regardless of being acceptable by the Block ontop of it or not, even though in that case it only wastes half the Energy Rate.

This Block is also a Fire Hazard. When active it can randomly set flammable things around it on Fire

The Burning Box requires Flint and Tinder or similar in order to be ignited.

It can be used together with a Smelting Crucible. Put the crucible on top.
