Assume the occupancy rate for office areas is 10m² per person and 10 L/s is required for each person. Occupancy rate for the office space: 96m² (net floor area per person) = 9.6 people (use 10) 10m² per person However, the actual number of people is 12, so this figure must be used. Quantity of air: 12 people x 10 L/s per person = 120 L/s
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 â„‰, with feedwater at 0 Psig and 212 â„‰. â€śBoiler horsepower, a unit of measurement of power of steam boilersâ€ť from Wiki.
ApplicationsUsing the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Pressure = â€¦

Can someone help, I have a steam boiler, and have the KG Per hour steam rating the boiler can acheive (15,000kg/hr) , and need to convert that to the water capacity the boiler will hold thanks. As cold water, 15000 kg is about 15000 L. However, I assume this is a closed system, the steam flows to a radiator or other load, is condensed and
A 500 hp boiler requires up to 115 gallons per hour of No. 2 oil. Using Table 2, and specifying a 1-inch nominal pipe size, gives 0.1 psi pressure drop at 100 gph, and 0.2 at 150 gph. Linear interpolation gives 0.13 psi pressure drop per 100 equivalent feet of pipe. Note that heavy oils require a return line, which increases total flow
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.
The average steam consumption of those engines (per output horsepower) was determined to be the evaporation of 30 pounds of water per hour, based on feed water at 100 °F, and saturated steam generated at 70 psi. This original definition is equivalent to a boiler heat output of 33,485 Btu/h.
Calculate the LPG (Propane) Consumption per Hour by Burner Size - Propane Gas Consumption A gallon of propane contains 91,502 BTU of heat energy whilst the BTU rating for appliances is in BTU per hour, based on burner size. Dividing 91,502 by the BTU per hour rating gives you the number of hours that one gallon of propane will last.
quantity of tubes results in more heating surface per boiler horsepower, which because of the restricted flow areas near the turn Packaged industrial watertube boilers are typically rated in pounds of steam per hour output at operating conditions and range from 10,000 to 134,000 lbs/hr.
Lbs Steam delivered per Hour. Large boiler capacities are often given in lbs of steam evaporated per hour under specified steam conditions. BTU - British Thermal Units. Since 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
Absorption chillers are available in two types: 1. Single Effect (Stage) Units using low pressure (20 psig or less) as the driving force. These units typically have a COP of 0.7 and require about 18pph per ton of 9 psig steam at the generator flange (after control valve) at ARI standard rating conditions.
Jul 24, 2017· Typically boilers of much size would have a steam meter that calculates flow. This is typically a sensor measuring the pressure drop across and orifice. If you donâ€™t have that, then you have two options. Option one is mainly for firetube style boi
Mar 17, 2015· Boiler Calculator watch tutorial view guide Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure. Does not include any evaluation of any complex boiler configurations or fluctuations in operation.
Quantity of steam generated per hour (Q) in kg/hr. Quantity of fuel used per hour (q) in kg/hr. its inclination, air flow pattern etc. In a relatively small boiler, with a capacity of 10 MW, the radiation and unaccounted losses could amount to between 1% and 2% of the gross calorific value of the fuel, while in a 500 MW boiler, values
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. What is the cycle of concentration if the chloride content of boiler water is 186 ppm and the feedwater chloride content is 38 ppm? What is the differential setting of an automatic pressure control that turns the
