Boiler Room 1 consisted of 5 single-ended boilers. It was on the Tank Top. It was connected to the 3rd funnel uptake with Boiler Room 2. This room was between Boiler Room 2 and the Reciprocating Engine Room.
Boiler Room 1 was mainly used to provide power when the ship was in port.
Boiler Room 1 was disintegrated when the ship broke up. The boilers can be found in the debris field.
Sinking[]
It's entirely possible that a couple of the boilers were lit up after the collision in an attempt to keep a steady supply of steam as the forward boiler rooms stopped producing steam when they became submerged. However, since none of the engineering crew who remained at their posts survived, it's hard to know for sure if these boilers were ever used during the sinking. However, if some of these boilers were lit up after the collision, then that could explain why some survivors saw lights remain on after the break-up
As each individual boiler room flooded, the fires in them had to be put out. This process gradually reduced the available power on board the ship through the sinking, as there ended up being fewer and fewer boilers remaining to carry the electrical load of the vessel. The gradual weakening of power on board was experienced in numerous ways throughout the night: lights were seen dimming and flickering on several occasions, the wireless signal progressively grew weaker through the night, and the lights began to glow a dull red minutes before the final plunge began. Additionally, some reported in the very late stages of the sinking hearing emergency power generators coming to life deep within the ship. In the end, boiler room 2 was likely one of the final boiler rooms left producing power for the ship-boiler room 1 had never been lit during the voyage, and whether or not it could have been lit in time to provide power during the sinking is questionable. The breakup occurred just over boiler rooms 1 and 2, and as such, it stands to reason that the breakup and subsequent destruction of the final two boiler rooms on board may have been the root cause of final electrical failure on board the ship, for the two events occurred almost simultaneously. Nevertheless this is disputed by accounts of survivors who watched her go down, and said that the break-up happened after the lights went out.
