Talk:Fire room

Airtight fire rooms
Here is a source describing airtight fire rooms circa 1890. There were 3 fire rooms serving 2 double ended boilers in each watertight boiler compartment.

There will be six double-ended boilers about 15 feet 6 inches diameter and 21 feet 3 inches long, and two about 11 feet 8 inches diameter and 18 feet 834 inches long for the main boilers, and two single-ended auxiliary boilers about 10 feet diameter and 8 feet 6 inches long. The boilers will be of the horizontal return fire tube type, all constructed of steel for a working pressure of 160 pounds per square inch. The main boilers will beplaced in four water-tight compartments, and the auxiliary boilers on the protective deck, as shown on the drawings. There will be three athwart-ship fire-rooms in each of the main boiler-compartments. Each of the double-ended boilers, 15 feet 6 inches diameter, will have eight corrugated furnace-flues, 3 feet 3 inches internal diameter, each of the double-ended boilers, 11 feet 8 inches diameter, will have four corrugated furnace-flues 3 feet 6 inches internal diameter, and each single-ended boiler will have two furnaces 2 feet 9 inches internal diameter. The' total heating surface for the main and auxiliary boilers will be about 43,272 square feet, measured on the outer surface of the tubes, and the grate surface 1,285 square feet. There will be in each fire-room in which the check-valves are placed an approved main and an ap: proved auxiliary feed-pump, and in each engine-room an auxiliary feed-pump. There will be three smoke-pipes.

The forced-draft system will consist of one blower for each fire-room, discharging into an air-tight fire-room. Air-tight bulkheads will be fitted so as to reduce the space to be maintained under pressure.

 * Good information. This points out that we really need a "History" subsection which would summarize this. Student7 (talk) 22:09, 13 September 2011 (UTC)
 * Here's some more

"Fire-room, or Stoke-hole. A room or space at the fronts of steam-boilers devoted to the management of the fires, and, generally, to all operations connected with the management of boilers under steam, such as feeding, observing pressures and temperatures, height of water in boilers, degree of saturation of water in boiler, blowing, etc. When the fronts of boilers face amidships, it is a fore-and-aft fire-room, and when they face forward or aft, it is called an athwart-ship fire-room." A Naval encyclopedia, LR Hammersley Co, 1880 (A US publication). The same sense is used in Journal of the Franklin Institute: Volume 59 - Page 132. In other words, the fire room is the part of the boiler room where the crew work, as opposed to that occupied by the boilers.

US naval terminology as of 1942: "Fireroom.-- A compartment containing boilers and the station for "firing" or operating same. Boiler room.-- A compartment containing boilers but not containing station for "firing" or operating the boilers" Nomenclature of Naval Vessels, US Navy, 1942 Dankarl (talk) 15:43, 14 September 2011 (UTC)

This page vs. "Engine room"
Large amounts of text on these two pages are identical. While certain aspects of the subject of vessel power and propulsion affect both the fire room and the engine room, the degree of overlap between these pages is rather absurd. I am not an expert on marine power engineering, so I don't feel qualified to edit this or the "engine room" page, but perhaps someone here can.ExpatSalopian (talk) 19:12, 9 November 2015 (UTC)
 * So where's the overlap? What is unwarranted overlap? Are you suggesting that they be merged, or that something ought to be removed? Andy Dingley (talk) 21:45, 9 November 2015 (UTC)
