Titanic Had Four Stacks
Titanic had four large funnels, also known as stacks. The engines of the ship ventilated the smoke through these funnels. Three of them worked as smoke stacks, and one as an air vent. When the boiler rooms began to take on water, there was a huge worry that the cold seawater hitting the warm steam stored in the funnels would cause them to explode. In an attempt to prevent this, the firemen and engineers had to quickly vent as much steam as possible from the stacks.
