For a gas fired boiler, the energy input is 1,000,000 Btu per mcf of gas. The boiler in Table 1 will use 1.338 mcf/hr to generate 30 bhp, the minimum operating level. Since only 10 bhp is needed, 20 bhp of steam goes up the stack as wasted energy.
If 1-kWh can produce 3.517 pounds of steam at the above zero-psig and 212-deg-F conditions, then 1,000 kWh will produce 3,517 lb/hr of steam. Step 4 Compute the flow rate of steam from a boiler based on burning 20 gallons/hour of No. 6 fuel oil, assuming normal 85 percent boiler combustion efficiency.
You need 666000 kcal. To produce one ton of steam, and every one m3 of gas gives 9520 kcal. So, around 69 m3 of gas will produce 1 ton of steam. In case of fuel & air and no scales in the boiler. Also by increasing the temperature of feed water will help to
S = 105 – 80. P2. Cut-in Pressure Delta. S = 25. Factor of Evaporation. Water enters the boiler at 225°F. The boiler pressure is 100 psi and the boiler water temperature is 338°F. The latent heat is 881 Btu.
The low-pressure steam cost is then calculated from the high-pressure steam cost as: C L = C H x (H SL – h W )/(H SH – h W ) where H SL = enthalpy of low-pressure steam, Btu/lb
3/11/2006 · The factor of evaporation is 1.08. BHP = (LB/HR*fe)/34.5 BHP = (LB/HR*fe)/34.5 BHP = 21500 * 1.08 / 34.5 BHP = 673 Where, BHP boiler horsepower Lb/Hr pounds per hour Fe factor of evaporation (can be assumed to be equal to 1) CYCLE OF
How much gas your boiler consumes will depend on its size, efficiency and how many hours it's in use per day. Boiler sizes are measured in kilowatts (kW) and range from 24-27 kW, 28-34 kW and 35-42 kW.
10/7/2017 · Corrosion damage in steam-condensing equipment and systems that collect, return and store condensate for reuse as boiler feedwater is a continuing problem at industrial plants, government installations, institutions, hotel, office and commercial buildings. Power

1 st Class Power (Operating) Engineer Certification and Examination Guide j. Typical monitoring, inspection, and overhaul procedure for a large steam turbine, gas turbine, large multi-stage pump, and large alternator. k. Rotating equipment monitoring including
Steam from the drum passes to the SuperHeater coils placed in the Flue gas path.. The steam temperature increases from the saturation temperature till the maximum required for operation. The superheated steam then finally goes to the turbine.Final Superheater temperatures are in the Range of 540 to 570 °C for large power plants and SuperHeated steam pressures are around 175 bar.
The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,300–1,600 °C (2,372–2,912 °F ). Some superheaters are radiant type (absorb heat by thermal radiation ), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of the two.
One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. Large boiler capacity is generally given in lbs of steam evaporated per hour, under specified steam conditions. Maximum continuous rating is the hourly
A boiler fired with natural gas costing $8.00/MMBtu produces 450-pounds-per-square-inch-gauge (psig) saturated steam and is supplied with 230 F feedwater. Using values from the tables, calculate the fuel cost of producing steam. Steam Cost = ($8.00/MMBtu/10
Thermal efficiency of boiler is defined as the percentage of. heat input that is effectively utilized to generate steam. There. are two methods of assessing boiler efficiency. 1) The Direct Method
1 Boiler Horsepower to Btus Per Hour = 33475.3592. 70 Boiler Horsepower to Btus Per Hour = 2343275.1449. 2 Boiler Horsepower to Btus Per Hour = 66950.7184. 80 Boiler Horsepower to Btus Per Hour = 2678028.7371. 3 Boiler Horsepower to Btus Per Hour = 100426.0776. 90 Boiler Horsepower to Btus Per Hour = 3012782.3292.
