SPOILER ALERT! This page includes details about the game's final boss.
The previous page covered the first 3 flamethrower enemies in THE DECK. After dealing with them, we continued through the level to get the STORAGE KEY, at the very top of the cavern, then climbed back down to the MAIN DECK. (Again, to the best of my knowledge, you must stand on the rusted hull near the STORAGE KEY to spawn the last 2 flamethrowers.)
THE DECK - FOURTH AND FIFTH FLAMETHROWERS (7-8/9)

Move to the edge of the MAIN DECK, just beyond the broken railing. Take a running jump onto the overturned hull and slide down to the CAVERN FLOOR.

Head to the left...

...past the pool and the huge propeller, toward the far side of the cavern.

Beyond the OVERTURNED HULL, turn right and save the game. Then hop your way up the hill to confront the 2 flamethrowers. They approach from the area with the movable crates, at the top of the hill on the right.
The goal is to separate them, so you can tell which one has set Lara on fire. Then quickly kill just that one, run to the pool to extinguish the flames, and return to repeat the process with the other one. If you accidentally kill one of them before he sets Lara on fire, you'll have to start over. Here's the sequence:

Move almost to the top of the hill and equip the grenade launcher, since it can kill a flamer with one hit. When the enemies emerge, make sure they're far enough apart so you can tell which one is targeting you. (If they're too close together, reload and try again.)

Let one of them set Lara on fire, then immediately kill him with a grenade.

Roll...

...and run/jump/slide down the hill...

...to the pool, feeding Lara medipacks as you go. Once you make it into the waist-deep water, the flames will extinguish.

If everything has gone well, save the game and climb the hill once more.

Let the second flamer set Lara on fire, roll...

...and run back down to the pool...

...to put out the flames.
Now level skip 7 times to reach the DRAGON'S LAIR. You will need to fight your way past the petrified spearmen and cultists at the beginning of the level to reach the boss arena, but if you use grenades and/or Uzis, it won't take long.
THE DRAGON'S LAIR - BARTOLI–DRAGON (9/9)

Save the game before triggering the transformation. Then move forward to wake the dragon.

Stand near one of the openings in the floor and let the dragon set Lara on fire. Then drop into the water...

...to put out the flames, and the achievement/trophy should pop. GG!
DARK MODE: I plan to add optional dark mode for these pages, but my current priority is updating the walkthroughs. Meanwhile, may I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's official add-on/extension site.)
