Read More4/12/2002 · If you assume that a given steam plant has a 50,000 lb/hr average load, then with a 5% blow down rate, you'd have to feed 52,500 lb/hr water to the boiler. If it's assumed that 1% of 52,500 is lost as DA vent steam, then that's 525 lb/hr.

Read More3/11/2006 · What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi? 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

Read MoreBoiler Horsepower - BHP. The Boiler Horsepower (BHP) is the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 ℉, with feedwater at 0 Psig and 212 ℉. "Boiler horsepower, a unit of measurement of power of steam boilers" from Wiki.

Read MoreBoiler Capacity - Steam boilers output can be expressed in Boiler Horsepower, MBTU or in Pounds of Steam delivered per hour Classification of Steam Heating Systems - Steam systems carries heat through pipes from the boiler to consumers as heat exchangers, process equipment etc.

Read More26/6/2017 · The equivalent weight of NaOH is 40, so 0.20 epm X 40 = 8 ppm caustic soda (50%) required. Dividing 8 ppm by 120 gives 0.067 lbs of 50% caustic soda per 1000 gallons of feedwater is required to produce 400 ppm total alkalinity as CaCO3 in the boiler.

Read More24/2/2012 · Normally steam consumed or generated in a steam boiler is more than what is required for use at the point of application. The difference in steam consumption and steam utilization is due to: Steam condensation when it travels on its way to point of use mainly due to exposed surfaces.

Read MoreThe larger the heating surface a boiler has, the more efficient it becomes. The quantity of the steam produced is indicated in tons of water evap-orated to steam per hour. Maximum continuous rating is the hourly evaporation that can be maintained for 24 hours

Read MoreUnit Descriptions 1 Horsepower (boiler): The energy rate needed to evaporate 34.5lb of water at 212 F (100 C) in one hour. Equal to 33,475 BTU/h. Approximately 9.810657 x 10 3.A boiler horsepower is more than 13 times larger than mechanical horsepower

Read MoreA 24 kW boiler will use 24 kW of energy per hour. If your boiler is on for a total of five hours per day, your daily usage should be around 120 kWh. But if you've noticed an increase in your gas bill recently, your boiler could be using more gas than it should. First, you should check with your supplier that they haven't increased the prices.

Read More13/12/2010 · One BHP (Boiler Horsepower) will produce 0.069 gallons per minute of condensate. Developing a formula results in: BHP x 0.069 x minutes of storage x 1.33 = Receiver size, in gallons Examples: 150 BHP Boiler 150(BHP) x 0.069 (gpm/BHP) x 10 (min) x 1.33

Read More17/3/2015 · 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.

Read MoreSince the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - …
