Burns a fuel mixture of volatiles and oxygen to produce high-temperature [[Water|Steam]].  The H2 Combustor should be fed a 2:1 ratio of volatiles to oxygen.  It will output mix of gases at 2500 C, made up of approximately 46.67% [[Carbon Dioxide]], 30% [[Water|Steam]], and 23.33% [[Pollutant|Pollutants]], plus trace amounts of unburnt volatiles and oxygen.
Burns a [[fuel]] mixture to produce high-temperature byproducts.  


To generate electricity with fuel instead, see the [[Kit (Gas Fuel Generator)|Gas Fuel Generator]]. Alternatively, the heat generated by the H2 Combustor may be used with a [[Kit (Stirling Engine)|Stirling Engine]] to generate power at a much lower efficiency.

Depending on the exact setup, and how efficiently the Stirling Engine can be cooled (best on cold non-vacuum planets like Europa and Mars), it's possible for the Stirling Engine to offset the power cost of H2 Combustor, Filtration, and the entire rest of the cooling system, resulting in a zero-loss or even net-positive system. Alternatively, the outputs may be air-cooled using radiators on cooler planets or in a vacuum.

=Characteristics=
** Only one of the two input pipes needs to be connected.  
* Consumes fuel from the input, requiring a 2:1 mix of volatiles to oxygen.  Imprecise ratios will result in lower production rate, and the unburnt excess in the output.
** Temperature chosen for pumping capacity calculation prioritizes liquid input temperature, then gas input temperature, then internal temperature, in that order.
* Produces approximately 46% more moles output than the fuel input consumed.
** Pumping capacity is distributed across both inputs based on the ''Setting'' logic parameter, which can also be adjusted through the control wheel.
* Rate of fuel consumption from the input, and thus rate of production, is based on the pressure of the input. The unit will consume 3.42 L of fuel from the input each tick.
*** If one of the inputs lacks sufficient contents to meet the demanded pumping capacity, additional contents are pulled from the other input in order to maintain the total pumping capacity at the cost of ratiometric balance, unlike the [[Gas Mixer]] where pumping is stopped altogether.

* The unit, and gas inside it, will interact with the surrounding environment, as well as radiating heat in a vacuum (and thus cooling the gas inside it).  In an air-filled room, this will significantly heat the surroundings.
* Has an internal volume of 1000 L, where the product of the combustion is stored before being equalized to the output [[pipe]].
* The initial temperature of the products is 2500 C.
** Equalization only happens while the combustor is powered on and only happens unidirectionally to the output pipe.
* The water in the output is initially produced as a liquid before rapidly evaporating due to the temperature.  This results in noticeable innate cooling of the output, up to ~100 C.  Further losses from radiation or convection cooling of the surroundings also assist with this.
** If the unit is switched off, whatever gas remains in the unit will continue cooling through radiation or convection without equalizing to the output pipe.
* Each tick that the unit is ''turned on'', it will first equalize its internal volume with the output pipe network, before pulling in and combusting more fuel to add to the internal volume.
 
** This only occurs when the unit is turned on, so if the unit is switched off, whatever gas remains in the unit will continue cooling through radiation or convection without equalizing to the output pipe.
* Each [[tick]] that the unit is ''turned on'', it will first equalize its internal volume with the output [[Pipe Network|pipe network]], before pulling in and combusting more fuel to add to the internal volume.
** Since the equalization occurs before more fuel is pulled in, after the first tick the unit is on, it will have gases stored inside it but won't have pushed any to the output pipe yet.
** Since the equalization occurs before more fuel is pulled in, after the first tick the unit is on, it will have gases stored inside it but won't have pushed any to the output pipe yet.
** Has a ''Mode'' variable that can be set to 0 to allow the unit to be kept on, and continue to push gases to the output, without pulling more fuel in.

The Combustor performs controlled combustion of a mixture drawn from a gas input and a liquid input. A control wheel sets the ratio taken from each, much like the Gas Mixer, and the combined mixture is combusted just before being passed to the output.

What the Combustor produces depends entirely on what is fed into it. See the Gases page to find what each combination combusts into.

Description

Burns a fuel mixture to produce high-temperature byproducts.

To generate electricity with fuel instead, see the Gas Fuel Generator. Alternatively, the heat generated by the H2 Combustor may be used with a Stirling Engine to generate power at a lower efficiency.

However, while lower efficiency than a Gas Fuel Generator, in terms of energy output per mole of fuel input, a Stirling Engine is a practical and effective first step for cooling the output due to the fact that it generates power from cooling, rather than consuming power to cool the output (such as with an Air Conditioner). Depending on the exact setup, and how efficiently the Stirling Engine can be cooled (best on cold non-vacuum planets like Europa and Mars), it's possible for the Stirling Engine to offset the power cost of the Combustor, Filtration, and the entire rest of the cooling system, resulting in a zero-loss or even net-positive system. Alternatively, the outputs may be air-cooled using radiators on cooler planets or in a vacuum.
