I've read the wiki article, but if anything, I'm even more confused than before. I gather from my observations and the wiki that there are 3 components to damage caused by flamethrower turrets:

• Contact damage (from being hit directly by the flame stream)
• Ground damage (from standing on ground that has been set on fire)
• Burning damage (from being set on fire)

In addition, the wiki information panels specify

• Over time: 13/s fire (contact damage)
• Area of effect: 90/s fire (ground damage)
• Area of effect size 2.5 (for which? Contact? Ground? Both?)
• Damage over time lasts 2 seconds (again, which damage?)
• 160% cumulative pre-space damage upgrades (+20% ea. space)
• 110% max fuel damage bonus (multiplicative)

but the article then includes information that is contradictory or does not follow:

When fully upgraded, flamethrower turrets are capable of doing 145.2/s Fire damage plus an additional 217.8/s damage

Not mathable from damage and upgrade numbers above...

for 8 seconds.

Not 2?

Furthermore, enemies caught in the stream are ignited for 30 seconds,

again, not 2?

and dealt 100 damage per second while on fire.

Affected by upgrades?

This makes them far more powerful than the gun turret or the laser turret

How? Gun turrets have 24×10＝240 un-upgraded DPS on uranium ammo, with +150% max shooting speed and +120%(bullet)+120%(turret) pre-space damage upgrades for 240×2.5×3.4＝2040 max pre-space DPS, far higher than any combination of the numbers above for flamethrower turrets.

Can anyone provide me a clear explanation of the mechanics and calculations behind flamethrower turret damage?

No, but I can provide this :

(Flame turrets are awesome.)
P.S.: (And though I haven't done the math to compare with laser/gun, they don't seem to consume much...)

I updated the wiki page, it should be more clear now.

Thanks, that's a lot clearer. Just one thing though: I see that contact damage is a flat number (3) instead of damage over time. Does this mean that turrets have a firing rate like the handheld flamethrower? If so, is it the same (60/s)?

Also a minor nitpick, but don't worms and spawners have fire resistance?

The shooting speed is 15/s, I added it to the page.

Yep, fixed on the page.
