  Steam Calculators: Boiler Calculat

  • ApplicationsMar 17, 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.

Online calculator to quickly determine Boiler Efficiency. Includes 53 different calculations. Equations displayed for easy reference.

May 29, 2008· Steam Explosion and TNT equivalance Steam Explosion and TNT equivalance The qreatest fear in steam is a boiler explosion. That happens when all the water is gone, and the boiler overheats and blows. In one of the early industry explosions, it was calculated that the combined explosion was the equivalent to a 500 pound bomb or 200 pounds

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.

Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of the fuel. Indirect Efficiency. The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%.

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 Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as

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 don’t have that, then you have two options. Option one is mainly for firetube style boi

Steam Boilers & Appurtenances, Combustion & Instrumentation Controls, Deaerators, Exhaust Systems, Heat Exchangers, Heat Pipes, Industrial Pumps, Water Heaters, Water Softeners, Boiler Seminars, Services & Parts. 3 Common Boiler Formulas BOILER HORSE POWER What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi?

4.) maximum steam generating capacity in pounds of tonnes per hours.This term is the most informative and easiest to understand if it refers to steam properties the boiler is designed for. (Large boiler capacities are often given in lbs or tonnes of steam evaporated per hour under specified steam conditions, for smaller boilers capacity is

uantity of steam supplied by boiler in a year y, Qsteam, 26072, Tons, Calculated from dry saturated steam requirement of 3.35 TPH @ 10 kg/cm2 and 1.1 TPH @ 5 . 22, Rated capacity of the boiler of the project activity at From & At 100^oC

In this study, the efficiency of a fluidized bed boiler having a steam production capacity of 462000 kg/h and 17.2 bar pressure was calculated by using indirect method.

In general steam heating is used to. change a product or fluid temperature; maintain a product or fluid temperature; A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).

Boiler Horsepower 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 Boiler Horsepower BHP = (LB/HR*fe)/34.5 Lb/Hr Pounds per Hour BHP = 21500 * 1.08 / …

Take the 10 ton gas fired boiler for example, we will introduce how to calculate the fuel consumption of the boiler. The 10 ton gas fired boiler has an output of 10 tons per hour, which is …

Dec 05, 2017· An important note on boiler sizing – all the supply piping in the basement should be insulated with a minimum of 1” of pipe insulation. A better choice would be 1-1/2” or 2” of pipe insulation. An un-insulated steam main is equal to a radiator and must be calculated and added to the above calculation. When operating a steam boiler

A boiler has a ‘from and at’ rating of 2 000 kg/h and operates at 15 bar g. The feedwater temperature is 68°C. The use of Equation 3.5.1 will determine a factor to produce the same result: Note: These values are all from steam tables. Using the information from Example 3.5.1 and the Equation 3.5.1 the evaporation factor can be calculated:

ton of produced steam. Efficiencies based on both the first and second laws of thermodynamics are calculated for a number of components and for the steam boiler.

Power is measured in joules per second, or watts. Along with watts, horsepower as a unit is also used. Until the invention of engines, power was not measured formally, and there were no units associated with it. After the steam engine was invented, James Watt, an inventor and an engineer, worked on improving it and on making it more efficient.
