Heat loss(deletion) calculation in generators

[adelfaidah]

Hey guys Idk if there is a forum with a detailed calculation of how much heat is deleted when using generators but I decided to do a test myself (pic for reference).

On the left insulated vacuumed chamber I put a coal generator with 600kg of 250C coal, On the right insulated vacuumed chamber I put a coal generator with 600kg of 20C coal. Spawned a dup to refuel both at roughly the same time then deleted the dups. Once the coal generators finished all the fuel I deleted them as well to more easily calculate the total heat of the co2 emitted inside the chambers. I gave the CO2 some time to roughly equalize across the chamber and then started calculating. The left chamber had 299.2g @approx 75C of CO2 in each tile. (since each chamber is 12 tiles large that = to around 6kg. The right chamber has the same amount (299.2g per tile) but at roughly 55C.

So I got the specific heats for Coal and CO2 (0.710DTU/g/c and 0.856DTU/g/c respectively). I converted all temps to kelvin to use the absolute 0 as my reference points and kg to grams to match the specific heat units so that gives us

Left chamber    : Coal : 600,000 g , 523K, 0.710 DTU/g/c 
                           CO2 : 6000g       , 348K, 0.846 DTU/g/c

Right chamber : Coal : 600,000 g , 293K, 0.710 DTU/g/c 
                           CO2 : 6000g       , 328K, 0.846 DTU/g/c

multiplying all these numbers for each row will give us the "total energy" the element with that much mass has at that temperature

Left chamber    : Coal : 600,000 g * 523K * 0.710 DTU/g/c  = 222,798,000 DTU or 222,798 kDTU or for simplicity
                                                                                              = 222,798 kJ
                           CO2 : 6000g       , 348K, 0.846 DTU/g/c.   = 1,766.    kJ

Right chamber : Coal : 600,000 g , 293K, 0.710 DTU/g/c     =124,818 kJ
                           CO2 : 6000g       , 328K, 0.846 DTU/g/c.   = 1,665.   kJ

this means in the left chamber we deleted 222,798-1,766 = 221,032 kJ! worth of heat
and in the right chamber its about                                      = 123,153 kJ worth of heat

This tells me two things :

1- generators, specifically coal generator for my example deletes a significant amount of heat in the process of making energy.
2- that amount of heat deleted only increases as you increase the temperature of your source fuel. (true the CO2 output got hotter as well compared to cooler coal, but that amount to almost nothing in terms of kJ due to the loss of 594kg in the process of coal to CO2).

am I making any mistakes here would love to hear your feedback.

*Note: I am aware that deleting the coal generator affected the heat values a bit as the building also had an increase in its temp, but the increase was so miniscule in that short period of time it was working and I deleted both generators so I think for the most part its negligible to include it in the calculation
