please keep this linesheet for future reference! BOILER TERMINOLOGY AND CONVERSION FACTORS Boiler Horsepower

– One boiler horsepower = 33,479 Btu/hr. heat to steam = 34.5 lb./hr. of water evaporated from and at 212°F = 9.8 Kilowatts

Dry Steam – Steam which contains no liquid water. Saturated Steam – Steam which is at the same temperature as the water from which it was evaporated. Wet Steam – Steam which contains liquid water. Its quality is less than 100%.

Enthalpy – Heat content, Btu/lb, of a liquid or vapor. Latent Heat of Vaporization – The heat required to convert a material from its liquid to its vapor phase without raising its temperature. The latent heat of vaporization of water at 1 atmosphere pressure and 212°F is 970.3 Btu/lb. Quality – In a mixture of steam and water, the weight percentage which is present as steam; in other words, the percent of complete vaporization which has taken place. The quality of saturated steam is 100%.

HANDY FORMULAS FOR BOILER SYSTEMS HEAT: 1 BTU = AMOUNT OF HEAT REQUIRED TO RAISE 1lb OF WATER 1 oF 1 BHP = 33,475 Btu’s / hour output o 1 BHP = 34.5 lbs of steam / hour from & at 212 F 1 BHP = 140 Sq Ft EDR 1 BHP = 10 kW (approx.) 1 BHP = 970 Btu’s / hr / lb of water 1 Sq Ft EDR = 240 Btu’s (steam) 4 Sq Ft EDR = 1lb Condensate WATER: 1 Gal of water = 8.34 lbs & 231 cu Ft 1 cu Ft of water = 7.48 gallons 1 cu Ft of water = 62.428 lbs @ 39.2 212 oF

PRESSURE: PSIG x 27.71 = “WC PSIG x 2.036 = “Hg Oz x .0625 = PSIG 1 Oz = 1.732 ”WC 1” WC = .577 Oz = .0361 PSIG = .0737” Hg Ft of Head = PSIG x 2.31 BHP -Boiler Horse Power EDR -Equivalent Direct Radiation PSIG -Pound -Force per Square Inch Gauge WC -Inches of Water Column Hg-Mercury

PPB -Parts Per Billion GPH -Gallons Per Hour CC -Cubic Centimeter

WATER TREATMENT: Oxygen content: cc / liter x 1.43 = ppm or x 1430 = ppb 1 Grain per gallon = 17.1 ppm How scale increases fuel consumption: 1/16” = 15% More fuel 1/8” = 20% 1/4” = 39% Oxygen Corrosion: 4 Fe (OH) 2 + O 2 + 2H 2 O = 4 Fe (OH) 3 ……...in other words: Ferrous Hydroxide + Oxygen + Water = RUST! Carbon Dioxide: CO 2 + H 2 O = H 2 CO 3 ……..or Carbonic Acid ELECTRICITY: AMPS (3 PH) = (kW x 1000) Divided by (Volts x 1.732) AMPS (1 PH) = (kW x 1000) Divided by Volts GPH Heated = (kW x 3412) Divided by (8.34 x Temp Rise) o 1 kWh will evaporate 3.5 lbs. of water from & at 212 F 1 kWh = 3412 Btu MISC: ( oC x 1.8) + 32 = oF ( oF - 32) x 5/9ths = oC Volume of a Cylinder in Gallons: length” x diameter Squared x.0034 -A water column 1 Ft high exerts pressure of .4333 PSI -Doubling the diameter of a pipe increases its capacity 4 times.
