Tried your mod, but it didn't work as intended. I tried to set up a power plant with your mod, but the generator continuously says there is no fluid input.
Even outputting to a tank doesn't work.

Also the fluid box for the output of the boiler doesn't fill up even after minutes of dumping fuel in it so i think the fluid box is broken.

I even checked the code for things that could cause the broken fluid box, but didn't find anything weird there (compared code with other working boilers).
I also tried to change the fluid type of the output to check for errors with the fluid but no success there.

The input of the boiler works fine though, which makes it even weirder.

I hope you can find a solution to it, because the mod in its current state is basically useless.

Ok, I gave my modding skills another try today and finally got it to work.

On the fluid I changed the heat capacity to 500kJ from 1GJ and set the default temp to 15°C and gas temp to 100°C (this is for graphics only).

On the entities i changed a bit more.

Changes on the boiler:
- target temperature set to 215°C
- fluid box size parameters like vanilla boiler
- energy consumption from 2.01GW to 2.4GW
- efficiency of burned fuel to 1.0 from 0.4
- emissions (pollution) value renamed to emissions_per_minute and set to 30 (like vanilla boiler)

Changes on the generator:
- changed maximum temperature to 215°C
- set fuel usage per tick to 0.2 (results in 1.2GW of electricity per generator)
- set minimum temperature for input to 100°C
- fluid box size parameters like vanilla generator

All that together made it work for me and makes the fluid usage values more suitable for the game (now 12/s per generator and 2 generators per boiler instead of something around 0.001 or even lower), which might have been an issue.

Feel free to use these changes in an updated version.

it is super high steam density and it burns stufff super fast to it was sorta expected

and due to certain IRL reason i still didnt find time to update the mod sorry
