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.
View MoreDec 05, 2017· To cover piping losses and what we call a pick-up factor, the boiler produces about 33% more steam than what’s listed in all manufacturers’ brochures. The square foot of steam listing in brochure is for connected load only. Don’t install a larger boiler than the system requires.
View MoreThe 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 oF, with feedwater at 0 Psig and 212 oF. A BHP is equivalent to 33,475 BTU/Hr or 8430 Kcal/Hr and it should be noted that a boiler horsepower is 13.1547 times a normal horsepower.
View MoreBoiler load - The horsepower, lbs of steam per hour, or BTU is the rating indicating the maximum capacity of a boiler. When a boiler operates at its maximum rated capacity, it is referred to as maximum load. If the load varies from hour to hour, it operates at a varying load.Load and load variations can influence the amount of chemicals required for treatment and the treatment controls required.
View MoreThe load factor is a dimensionless number equal to the average load divided by the peak load. For example, if the average load is 66 kWh/d (or 2.75 kW) and the peak load is 10.5 kW, the load factor is 2.75 kW/10.5 kW = 0.26.

View MoreFor boilers and process heaters that co-fire natural gas or refinery gas with a solid or liquid fuel, the load fraction is determined by the actual heat input of the solid or liquid fuel divided by heat input of the solid or liquid fuel fired during the performance test (e.g., if the performance test was conducted at 100 percent solid fuel firing, for 100 percent load firing 50 percent solid fuel and 50 percent natural …
View MoreThe capacity of the boiler should have ten liters of water and the working pressure must be 3.4 Kgf/cm2 (kilogram-force). This article discusses what is a steam boiler and its types used in power stations for generating steam.
View MoreNov 03, 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 per hour Fe factor of evaporation (can be assumed to be equal to 1)
View MoreThe nature of the facility’s operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications with the boiler supplying water to the system at 180 °F to 220 °F. The operating pressure for hot water heating systems usually is 30 psig to 125 psig.

View MoreAlthough the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator .
View MoreAnother important factor in instantaneous boiler response is steam chest volume. All steam piping and boiler steam space will maintain a reservoir of steam. If you determine the volume of this area, you can use steam specific volume data to determine the mass of steam stored. For example, if a boiler has a steam space of 3 cubic feet and there are
View MoreFire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.
View MoreDec 11, 2017· Formula for Steam Boiler Efficiency Efficiency of any boiler can be expressed as the percentage of total heat exported by outlet steam in the total heat supplied by the fuel i.e. Steam Boiler Efficiency (%) = Heat Exported by Outlet Steam x 100 / Heat Supplied by the Fuel
View MoreA single unit of coal (4MJ) fed into a boiler and then utilised in a steam engine will result in 4MJ of energy added to an electrical system. It costs 30kJ energy to heat 1 unit of water to steam at 165°C, so one boiler will produce 60 steam per second.
View MoreThere are several factors that influence the energy performance of boilers including fuel characteristics, firing method, steam pressure, and heating capacity. The main challenge to ensure optimal operating conditions for boilers is to provide the proper excess air for the fuel combustion.
View More3. Ready and accurate response of rate of fuel feed to load demand (usually as reflected in boiler steam pressure). 4. Continuous and reliable ignition of fuel. 5. Practical distillation of volatile components of coal. 6. Adequate control over point of formation and accumulation of ash, when coal is the fuel.
