In 1930, SAR Class 8X no. 883, a 2-8-0 Consolidation that had been built by the American Locomotive Company (ALCO) for the CGR in 1902, was reboilered by the SAR with a purpose-built boiler. At the same time, it was superheated, converted to a 4-8-0 Mastodon wheel arrangement by replacing the leading pony truck with a bogie, and reclassified to the sole Class 8R .
Please enter the dimensions of your room (metres), including the area of all windows (metres 2) if applicable. Height (metres) Width (metres) Length (metres) Glazed Area (metres2) Squared area = times the total height by the total width. Enter "0" if there are no windows in this room.
Boiler Efficiency: Introduction and Methods of Calculation
To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

For ease of installation and minimal disruption, its best to have your new boiler fitted in the same place as the old one. Most people tend to go for kitchens or cupboards, but you can place it in almost any room, as long as it has the correct pipework and you can position the flue correctly.

How to Calculate Boiler Steam Flows | Hunker
12 Direct method In the direct method, the boiler efficiency is directly defined by the exploitable heat output from the boiler and by the fuel power of the boiler: φoutput η= (14) φinput where φ output is the exploitable heat output from boiler, and φ input the fuel power of the boiler.
