Immolation Bomb:
Does the half-orc .5/level damage bonus increase the per round damage with this discovery? Prerequisite: Alchemist 3
Benefit: When the alchemist creates a bomb, he can choose to have its substance coat the direct target’s body, causing the bomb to deal its damage over time instead of all at once. The bomb’s effect lasts for a number of rounds equal to the number of damage dice the bomb would normally deal (for instance, a 5d6 bomb lasts for 5 rounds). When the bomb hits the direct target, the bomb deals 1d6 + the alchemist’s Intelligence modifier in damage, and those within the splash zone take damage equal to 1 + the alchemist’s Intelligence modifier. It repeats this damage against the direct target of the bomb each round the immolation bomb lasts, dealing the damage at the start of the alchemist’s turn. Splash damage is dealt again to any creature that is adjacent to the direct target when it takes damage from the immolation bomb. A creature taking damage from an immolation bomb’s direct hit can attempt to extinguish the flames as a full-round action that requires a Reflex save (DC = 10 + 1/2 the alchemist’s level + the alchemist’s Intelligent modifier). Because of the alchemical nature of this bomb, rolling on the ground does not grant a bonus on the saving throw, and dousing a creature with water does not stop it from burning. These bombs can be used underwater.

Yes it should.
Is it safe to assume any bonus for PBS would only apply on the first round?
As long as you threw the bomb within 30', the +1 from PBS would be added to the first round of bomb damage. On subsequent rounds, you would not apply the +1 from PBS because it is no longer damage from a ranged weapon attack, but instead damage from the Immolation Bomb ability.
