Regarding a more accurate Gas combustion/synthesis Ratio

[wary oracle]

The gas combustion ratio in the current Beta Version is in a very strange state. For example, burning 2 parts hydrogen can produce 3 parts water. This will cause a lot of confusion for players, especially those familiar with chemistry. The correct proportions are etched deep in the players' memories.
I believe a more accurate and realistic combustion ratio would make most players feel more comfortable.
I suggest the following changes.

All gases containing hydrogen atoms produce water when burned, including Methane, Hydrogen and Alcohol. In the current version, these gases produce Pollutants and Carbon Dioxide when burned with oxygen, but produce Steam and Pollutants when burned with Ozone. They should be changed to burn with oxygen to produce only Steam and Carbon Dioxide.
I've been sharing and discussing this idea on the atmospherical-chitchat channel for many days now. Some players have questioned whether this makes it easier to obtain water and thus disrupts the game balance. After calculation and consideration, I believe this will not be a factor that disrupts the game balance. In the process of burning Volatiles to produce water, methane replaces the volatiles. Hydrogen currently accounts for only a very small proportion. For example, the hydrogen content in the Vulcan atmosphere is only 10% of the original Volatile content. The fact that water can only be produced by burning hydrogen makes obtaining water even more difficult.

Based on the above, I have developed a proposed modification to the gas combustion ratio, in which I treat the Pollutant as Propylene for calculation.
I also developed a gas synthesis route and demonstrated its feasibility and lack of gas omission using the environment of Vulcan.

Some players have also pointed out that when using a welding torch indoors, the water produced by the combustion may accumulate on the ground and damage electrical wires. In the game, small amounts of water don't actually accumulate on the ground; the steam produced by combustion might pose a new challenge for engineers, perhaps by making greater use of Arc Welding.
Regarding the combustion products with rocket propulsion, this problem might be solved by modifying the calorific value of the combustion gases. This will have less impact on other aspects and maintain the necessary game balance.

Combustion energy impacts gfg power generation and the temps affect combustion machine’s rpm

[wary oracle]

You're right. I just discussed this issue with other players. I have a better idea about the rocket now. The calculation of rocket thrust can be simplified to Conservation of momentum. Current rocket thrust is related to combustion temperature and the mass of combustion products.
We only need to add an intermediate calculation. Combustion temperature is converted to pressure using the ideal gas equation. Then, the pressure is converted into jet velocity using a power function. The thrust of a rocket is determined by its jet velocity and the mass of its combustion products.
This should preserve the computational framework of rockets while allowing for the adjustment of the power function to balance the thrust from different gas combustion processes.
For details on this issue, please refer to the Convergent-Divergent Nozzle.

My thoughts so you can refine your approach better.

Water being this abundant completely throws off the survival loop for water. On one hand it is more common, but the other hand it requires cooling. But water is just not a good gas to have in your furnace because of how much energy it takes to change its temperature.

I will assume combustion energy numbers aren't finalized because this touches on many things. The equations arent balanced with the old number even if the end result temperature is the same. Take Methane and O2 combustion, going for 3 polutants 6 CO2 to 2 Water 1 CO2 is an overall reduction of total energy capacity. You went from an energy density of 243.6 to 172.2. If this stays the same temp then that means this reaction releases LESS energy. This directly affects the ability to heat especially for furnace operation. It will also affect gas fuel generator operation because the energy conversion is based on the energy released from the combustion. Less energy means less power which leads to gfg performing worse than a sfg. Throws that balance off as well. If you preserve the energy numbers that means this reaction must naturally be hotter, this will affect the combustion centrifuge and deep miners.

Speaking of furance... this could make pressures/temps worse on the furnace. Less gases released via the combustion means you burn fuel just to get heat in. Some reactions you have actually LOWER the pressure of the temperature (Hydrogen + O2) because the count of mols reduces. Granted this could be an interesting point for trying to get heat into the furnace, but it makes vacuum worlds more reliant on ices to get gas for pressure as opposed to just burning VOL+O2 fuel and have 3x more gas for pressure as before.

I do want to point out a closed water loop with plants. Can this make enough water for you to survive off and CO2 to feed the plants without any direct input from the player?

I... Kind if really hate this

Too many of the easily accessible volatiles don't produce undesirable waste

Specifically, if you're removing Pollutants from any of those reactions I believe you are breaking a fundamental game rule.

[wary oracle]

I think I can accept that combustion produces some Pollutants, but I really find it hard to believe that combustion cannot produce Water.

It seems like water production is neutered for gameplay difficulty, but in reality, Methane as other Hydrocarbons would produce plenty of water too.

[vagrant locust]

yeah but we can't have Humidity. it'll always Condense

pretty sure that's why it doesn't produce water

[craggy flame]

It'll result as water vapor of course. But a combuster is not open to the environment, just like the pollutants and CO2.

If burning H2 with O2 is producing H20 as a gas/vapor (whether or not it condenses in the output pipe)... Then having CH4 must also do the same.

you're asking to introduce water condensation in a stage where a novice player at least has no idea how to deal with it

I may not like the particular handwave, but I see where it comes from
