In order to calculate the steam lbs/hr on a heat exchanger, you need to know the following information: the boiler horsepower, the heater surface area, and the overall heat transfer coefficient. Once you have this information, you can use the formula:
Steam lbs/hr = Boiler Horsepower * Heater Surface Area * Overall Heat Transfer Coefficient
For example, let’s say you have a boiler that is 1000 horsepower and a heater surface area of 100 square feet. If your overall heat transfer coefficient is 80%, your steam lbs/hr would be:
- Determine the steam pressure at the inlet and outlet of the heat exchanger
- Use a pressure-enthalpy diagram to determine the specific enthalpy of the steam at each point
- Calculate the mass flow rate of steam through the heat exchanger using the inlet and outlet pressures and specific enthalpies
- Convert the mass flow rate to pounds per hour using the appropriate conversion factor
How is Steam Lb/Hr Calculated?
To calculate steam lb/hr, you need to know the steam’s pressure, temperature, and flow rate. Once you have this information, you can use the formulas below to find the steam’s weight.
P = pounds per square inch
T = degrees Fahrenheit Q = volumetric flow rate in cubic feet per minute
How Do You Calculate Steam Per Hour?
When it comes to calculating steam per hour, there are a few different variables that you need to take into account. The first is the type of boiler you’re using. There are two main types of boilers – fire-tube and water-tube.
Each one has a different method for calculating steam output. Fire-tube boilers are the most common type of boiler used in small and medium sized industrial settings. Their name comes from the fact that they have their combustion chamber located within the tubes that make up the body of the boiler.
To calculate steam output on a fire-tube boiler, simply multiply the boiler’s evaporation rate by its heating surface area. Water-tube boilers are less common than fire-tube boilers, but they’re still used in some large industrial settings. They get their name from the fact that their combustion chamber is located outside of their tube structure.
Calculating steam output on a water-tube boiler requires knowing both the evaporation rate and heat transfer rate of the boiler. Once you have those numbers, simply multiply them together to get your answer. No matter which type of boiler you’re using, it’s important to remember that these calculations are only estimates.
How is Steam Consumption Calculated in Heat Exchanger?
In order to calculate the steam consumption of a heat exchanger, you will need to know the following information:
1. The temperature of the steam (in °C)
2. The pressure of the steam (in bar)
3. The flow rate of the steam (in kg/s) 4. The heat duty of the heat exchanger (in kW) 5. The efficiency of the heat exchanger
With this information, you can use the following equation to calculate steam consumption: Steam Consumption (kg/s) = Heat Duty (kW) / ((1-Efficiency)*(Enthalpy of Saturated Steam – Enthalpy of Dry Steam))*1000 where Enthalpy is in kJ/kg and Efficiency is a unitless number between 0 and 1.
How is Steam Rate Calculated?
The steam rate is the amount of heat that is added to or removed from a substance by the application of steam. The SI unit of steam rate is watts (W), although it is sometimes expressed in British thermal units per hour (Btu/h). The rate at which steam is applied to a substance is usually controlled by a valve, and the amount of heat that is transferred can be calculated using the equation:
Q = m•Cp•ΔT Where: Q = Heat transfer (in watts)
m = Mass flow rate of steam (in kilograms per second)

Steam to Water Heat Exchanger Calculator
When it comes to calculating the heat exchange between steam and water, there are a few different variables that need to be considered. The first is the temperature of the steam, which will affect how much heat is transferred. The second is the specific heat of the water, which will also affect how much heat is transferred.
And lastly, the rate of flow for both the steam and water also needs to be considered. Luckily, there’s a helpful tool that can take all of these variables into account and help you determine the amount of heat that will be exchanged between your steam and water – a steam to water heat exchanger calculator! To use this calculator, simply input the temperature of your steam, the specific heat of your water, and the flow rates for both fluids.
Once you have this information entered, click “calculate” and you’ll instantly see how much heat will be exchanged between your two substances. This tool can be incredibly helpful when trying to optimize a heating or cooling system involving both steam and water. By understanding exactly how much heat will be exchanged under different conditions, you can make sure that your system is running as efficiently as possible.
Steam Flow Rate Kg/Hr Formula
The steam flow rate through a given pipe is often measured in pounds per hour. However, this can be converted to kilograms per hour by using the following formula:
steam flow rate (kg/hr) = steam flow rate (lb/hr) * 0.45359
For example, if the steam flow rate through a pipe is 150 lb/hr, then the corresponding steam flow rate in kg/hr would be 68.04 kg/hr. This conversion is important because it allows for comparisons to be made between different units of measure. For instance, if the steam pressure in a certain system is known to be 5 bar, and the desired steam flow rate is 500 kg/hr, then the required pipe diameter can be calculated using the following formula:
pipe diameter (mm) = 500 / (5 * 686) where 686 is a constant that takes into account various factors such as density, viscosity, and friction. This calculation would give a result of approximately 25 mm.
Steam Calculation Formula
If you’re a home improvement enthusiast, you’ve probably come across the term “steam calculation.” But what exactly is it?Steam calculation is a way to determine the amount of steam that can be generated from a given amount of water.
This information is important for many reasons, including: – Determining the size of boiler needed for a job – Knowing how much water will be required to generate the necessary amount of steam
– Estimating the cost of running a boiler Fortunately, there’s a fairly simple formula for calculating steam output. All you need is a few pieces of information:
1. The temperature of the water (in degrees Fahrenheit) 2. The pressure at which the steam will be generated (in pounds per square inch, or PSI) 3. The specific heat of vaporization of water (a constant known as “latent heat”)
4. The time over which the steam will be generated (in minutes)
Steam Consumption Calculation Xls
In order to calculate steam consumption, you need to know three things: the mass flow rate of steam, the specific enthalpy of the steam, and the time over which the steam will be used. The mass flow rate is simply the weight of steam that will be used per unit of time. The specific enthalpy is a measure of the energy content of the steam, and is typically expressed in British Thermal Units (BTUs) per pound.
Finally, you need to know how long the steam will be used for in order to calculate how much fuel will be required to generate it. Once you have these three pieces of information, you can plug them into a simple equation to calculate steam consumption: Mass Flow Rate x Specific Enthalpy x Time = Steam Consumption
For example, let’s say we want to calculate the amount of fuel required to generate 1,000 pounds per hour of saturated steam at 500 degrees Fahrenheit. We would first look up the specific enthalpy of saturated steam at 500 degrees Fahrenheit, which happens to be 1,194 BTUs/pound. Then we would plug our numbers into our equation:
1,000 lb/hr x 1,194 BTUs/lb x 1 hr = 1,194,000 BTUs/hr This tells us that we would need 1,194 MBtu/hr (1 million British Thermal Units per hour) worth of fuel to generate our desired amount of steam.
This blog post explains how to calculate the amount of steam in pounds per hour that a heat exchanger can handle. The formula for this calculation is: steam flow rate (in lbs/hr) = heat exchanger surface area (in square feet) x temperature difference (in degrees Fahrenheit) x steam pressure (in psi). To use this formula, you will need to know the surface area of the heat exchanger, the temperature difference between the steam and the fluid being heated, and the steam pressure.
Once you have these values, plug them into the formula and solve for the steam flow rate.
