Funnels

Hello there Titanicans,
Like countless others before me, I've been fascinated by the Titanic for as long as I can remember but I'm new to the forum and have already learned so much new stuff about the Titanic and its sad demise it's just not true.

It's quite normal that newbies on any forum will always start by asking questions that have probably been asked hundreds of times before but here goes--
(I tried using the search facility but I was unable to persuade it to help me. Doubtless with time I will learn! :rolleyes:)
1. I have seen the Titanic usually referred to as RMS, I think I have always understood that (Royal Merchant Ship - am I right??) but 'SS Titanic' too.
I assume that SS stands for Steam Ship but why would it be refered to as such rather than RMS, if in the case of the Titanic it does mean Steam Ship?

2. I'm currently building my 2nd model of the Titanic and have a question regarding colours.
Is there a source of information regarding paint colours used throughout the Titanic, or at least a guide to general colours in use around 1912
One colour I'm specifically interested in is the colour of paint used on the inside surfaces of air vent openings on deck. I seem to remember that a dark red was not uncommon in navy/merchant ships but would be interested to know what others think or know.

3. Also on both sides of each funnel there appear to be tectangular section vents facing in opposite directions clearly visible on the commonly avaiable section view of the ship.If these are in fact vents, would their inside colour be identical to other on-deck vents?

4. Even my wife knows that the Titanic had four funnels (because I asked her!) but it was only a few days ago that I learned that it was planned she have three funnels but it was thought that a ship of these gigantic proportions should be fitted with four.
So far so good!
Now my question was simple. Which funnel was the 'fake'

I examined all the photos of Titanic available to me and online and came to the conclusion it was the rearmost, sorry, aftmost(?) funnel which also seems to have different inserts at the top to the other three as though anybody would be able to look down on it!
So once again am I right?

I'm not trying to be clever with my asumptions just genuinely interested in the answers and hope to be able to join in the conversations here from time to time.

Kind regards
Roger Fairhurst

To question No. 1. RMS and SS Titanic were both used. RMS was only for ships carry mail. SS stands for steam ship which was also used. The passenger list for example had both printed, the US Inquiry had mention of SS Titanic.

To question No. 4, the 4th funnel was the so called dummy funnel. It is not quite right as it has is own function. While it was not connected to the boiler rooms it was used as a vent for the turbine engine room as well as for the pantries. It has also an exhaust pipe for the smoke of the pantries, kitchens and from the fireplace of the 1st class smoking room (which was the only full function one) so smoke did come out of the 4th funnel too.
That large ships should have 4 funnels is not quite right, the Imperator Class had all 3 funnels.

To No. 3, the inside was "white" but it would look dark from the distance.

I would recommend the book "Titanic the ship magnificent Vol. 1" which might have some details you need.

Moderator's note: Later tonight NYC time, this thread will be copied from GT into three separate locations where discussion of the three subjects raised in the first message---RMS, model-making and funnels---are already addressed. Please don't post any additional responses while this is still in GT. Thanks.

Hello, I wanna know how the Funnels function? basically how the Boiler's smoke travel all the way to the top? I can't seem to find any thread of this, but if there is and I just missed it, I apologize. Just genuinely curious on how they function, like from Boilers, to smoke box, and to the top, in what direction and what are the flows.

Thank You!

If you buy the Haynes book title : RMS TITANIC Owner's Workshop Manual book. It will help a lot in explaining on the working of the ship.

Kiefer, basically the funnels are high chimneys and the smoke moves up as the hot air rises. In addition there was a forced draft pumped in at the bottom to assist combustion that also drove the smoke/hot air out through the funnels. Also the movement of the ship created a 'draw' vacuum at the funnel tops that sucked the smoke out. This varied with the speed of the ship, wind velocity and direction. The boiler uptakes were carefully designed so that extraction was balanced across a boiler room so that no individual boiler received a greater draw than its neighbours, thus firing rates remained the same on all the boilers at the same time. It's more complex than you might expect.
