(Saturated Liquid) Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
Boiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines.. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.
Mar 06, 2016 · An engine which didn’t really work that well was rated at 170,000 flbs. The Virginia Tripplex had an interesting history. This was a ridiculous 2-8-8-8-4 loco and suffered from simply using so much steam, the boiler couldn’t produce enough. Only one was ever built, and this was eventually split into two separate locos.
The Gas Producer Combustion System. As a comparison, the efficiency of a typical modern locomotive boiler with a huge combustion chamber was less than 50% at maximum output. Porta's 2-10-2's, built in the late 1950's and early 1960's, attained 78 to 80% efficiency at high output under documented tests.
Number/Capacity Required. It is usual practice to fit 2 injectors to a model steam locomotive, for redundancy reasons more so that capacity issues, and 2 injectors are mandatory if they are the sole and only means of feeding water to the boiler. This partly due to capacity, but the most important reason is redundancy as it is critical to have working boiler feeds.
Conventional steam locomotives, by contrast, required constant attention from at least one fireman to keep the steam, fire, and water all balanced to prevent a boiler explosion. Boiler Pressure was rated at 300 psi with fire-tube arrangement and superheater .

Tank locomotives are good candidates for pot boilers since the tanks hide the fire shield. A suction fan and blower are not needed for firing since there is no necessity for a forced draft. Pot boilers have large water capacity and simple to steam.
Union Pacific steam locomotive No. 4014, the Big Boy, is in one piece again nearly two years after the behemoth was disassembled to begin its restoration. The Union Pacific Steam Team recently hoisted the Big Boy’s more than 250-ton boiler and rear engine into the air with two massive cranes and reconnected it to its front engine.
As a modification of the saddle tank, pannier tanks locomotives were introduced by the Great Western to permit the use of a Belpaire boiler. This is shown above right. There are several examples of GWR pannier tanks, but the most popular is the 5700 0 - 6 - 0PT class which had a
Members Only. (For example, steam at 100% quality contains no liquid water and appears as a 100% clear gas, while steam at 90% quality contains 90% steam by weight and 10% water by weight in the form of a fog, cloud, or droplets.) Water droplets in high-velocity steam can be as abrasive as sand particles.

4-8-8-4 "Big Boy" Steam Locomotive In the Whyte notation for the classification of steam locomotives by wheel arrangement, a 4-8-8-4 is a locomotive with a four-wheel leading truck, two sets of eight driving wheels, and a four-wheel trailing truck. 4-8-8-4s are commonly known as "Big Boys".
Starting tractive effort at 80% boiler pressure 28,000 lb. * The adhesion ratio or factor of adhesion of a locomotive is the weight on the driving wheels divided by the starting tractive effort. A common rule-of-thumb for a steam locomotive states that a good factor of adhesion equals or exceeds 4, but not by much.
The locomotive weighed some 409 tons, was rated at 4,500 horsepower, produced 199,000 pounds of tractive effort, and could haul more tonnage on less fuel than convention steam engines, but
Twenty-five Big Boys were built exclusively for Union Pacific Railroad, the first of which was delivered in 1941. The locomotives were 132 feet long and weighed 1.2 million pounds. Because of their great length, the frames of the Big Boys were "hinged," or articulated, to allow them to negotiate curves. They had a 4-8-8-4 wheel arrangement, which meant they had four wheels on the leading set
Steam locomotives. Supplies of fuel (usually coal but sometimes oil) and water could be carried on the locomotive frame itself (in which case it was called a tank engine) or in a separate vehicle, the tender, coupled to the locomotive. The tender of a typical European main-line locomotive had a
The steam locomotive was a self-sufficient unit, carrying its own water supply for generating the steam and coal, oil, or wood for heating the boiler. The diesel locomotive also carries its own fuel supply, but the diesel-engine output cannot be coupled directly to the wheels; instead, a mechanical, electric, or hydraulic transmission must be used.
