Learn MoreBoiler 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.

Learn MoreBy the following formula we can find steam flow rate d : Pipe Inner Diameter (m) v : Steam Velocity (m/s) ms : Steam Flow Rate (kg/h) V : Specific volume (m³/kg)

Learn MoreJul 28, 2009 · Since you usually talk about gpm to the boiler, a rule of thumb is divide the number of PPH of steam out by 500 and that is the number of gpm you need to put into the boiler. 1000 PPH steam/500 = 2 gpm into the boiler. If your feedwater temperature is above 212F you can produce more than 34.5 PPH/BHP still at 0 psig.

Learn MoreFeb 12, 2021 · 33-A boiler of generates 85 TPH of steam at pressure 65 kg/cm2 & temperature 490 deg C, calculate the velocity of this steam if it passes through 150 NB steam line. Velocity of steam inside the pipe line = Flow in steam line (m3/sec) / Area of steam line (m2) Convert steam flow 85 TPH into m3/sec. That is 85000 kg/hr / Density of steam

Learn MoreDec 29, 2019 · Homework Statement:: Natural gas is burned in a shell and tube boiler to raise 5 tonnes per hr of dry saturated steam at 4.0 bar g. Condensate is returned to boiler at 4.0 bar g., 100 degrees C. i) calculate mass flow rate of natural gas required (kgs-1) ii) the steady state heat supplied to the heating application (MW)
