Lbs of steam to kwh
When you're designing a heating system it's often necessary to convert between the measurements commonly used with your energy source and the unit — typically British Thermal Units or heat units — used to measure your output heat. If you're converting from pounds of steam, for example, you can use a simple rule of thumb for a quick estimate or multiply by a conversion factor to get the precise number.
Steam heating has been used for a long time, so its relationship to BTUs, horsepower and other measurements is well established. For the low-pressure steam typically used in heating systems, that ratio is 1, BTUs for every pound of steam the system provides.
If your boiler supplies pounds of steam per hour, for example, you would multiply pounds by 1, to arrive at a figure ofBTUs. From there you'd need to calculate how best to distribute that heating potential throughout your structure, which involves a different set of calculations.
Since the actual conversion factor of 1, BTUs per pound of steam isn't convenient for mental math, it's often useful to round down to 1, BTUs per pound. This quick calculation is handy in a number of ways. If you're deciding between boilers of differing capacities, for example, that fast mental math can tell you which boiler is closer to meeting your needs. It also provides you with a fast mental check on your calculations: If you divide your BTUs by 1, and the number you get isn't close to the number of pounds of steam you're working with, there's probably an error in your math.
The more pounds of steam in your system, the less accurate this rough-and-ready estimate becomes, so you should follow through by calculating the stihl ms261 problems numbers.

The conversion table will allow you to quickly convert various measures of capacity. The table and formulas can help you size and pick out components such as condensate pumps and boiler feed pumps. Some additional conversion factors that may prove helpful are shown below. Conversion Factors.
Heating Water with Steam. Example :. Sizing a Boiler Feed Pump Receiver. The receiver tank should be able to hold five minutes worth of condensate for boilers up to BHP and 10 minutes of condensate for boilers over BHP. An additional 33 percent should be added as a safety factor. Developing a formula results in:. BHP x 0. Examples :. Select an available receiver tank equal to or larger than Probably a gallon tank will be the standard commercially available tank.
In other words, the BHP boiler needs about a gallon receiver. For the BHP and over boilers, this fast estimating results in receivers slightly larger than a calculated one. For smaller boilers under BHP, a slightly receiver size results than if calculated. The difference between the calculated and estimated size will probably be insignificant when selecting from the available receivers, since it would be cost prohibitive to get a special receiver made.
Table 1. Boiler H.We've made some changes to EPA. You may need a PDF reader to view some of the files on this page. This page describes the calculations used to convert greenhouse gas emission numbers into different types of equivalent units. Go to the equivalencies calculator page for more information. Most users of the Equivalencies Calculator who seek equivalencies for electricity-related emissions want to know equivalencies for emissions reductions from energy efficiency EE or renewable energy RE programs.
Calculating the emission impacts of EE and RE on the electricity grid requires estimating the amount of fossil-fired generation and emissions being displaced by EE and RE. EE and RE programs are not generally assumed to affect baseload power plants that run all the time, but rather marginal power plants that are brought online as necessary to meet demand.
For reference, to obtain the number of grams of CO 2 emitted per gallon of gasoline combusted, the heat content of the fuel per gallon can be multiplied by the kg CO 2 per heat content of the fuel. For reference, to obtain the number of grams of CO 2 emitted per gallon of diesel combusted, the heat content of the fuel per gallon can be multiplied by the kg CO 2 per heat content of the fuel.
Inthe weighted average combined fuel economy of cars and light trucks was Inthe ratio of carbon dioxide emissions to total greenhouse gas emissions including carbon dioxide, methane, and nitrous oxide, all expressed as carbon dioxide equivalents for passenger vehicles was 0.
The amount of carbon dioxide emitted per gallon of motor gasoline burned is 8. To determine annual greenhouse gas emissions per passenger vehicle, the following methodology was used: VMT was divided by average gas mileage to determine gallons of gasoline consumed per vehicle per year. Gallons of gasoline consumed was multiplied by carbon dioxide per gallon of gasoline to determine carbon dioxide emitted per vehicle per year. Carbon dioxide emissions were then divided by the ratio of carbon dioxide emissions to total vehicle greenhouse gas emissions to account for vehicle methane and nitrous oxide emissions.
Note: Due to rounding, performing the calculations given in the equations below may not return the exact results shown. To determine annual greenhouse gas emissions per mile, the following methodology was used: carbon dioxide emissions per gallon of gasoline were divided by the average fuel economy of vehicles to determine carbon dioxide emitted per mile traveled by a typical passenger vehicle.
Note: When using this equivalency, please keep in mind that it represents the CO 2 equivalency of CO 2 released for natural gas burned as a fuel, not natural gas released to the atmosphere. Carbon dioxide emissions per therm can be converted to carbon dioxide emissions per thousand cubic feet Mcf using the average heat content of natural gas in The average heat content of crude oil is 5.

Technically a steam turbine is a particular type of steam engine. A classic steam engine usually refers to a reciprocating steam engine, which uses a piston and crank arrangement, where pressurised steam from the boiler forces the piston through its stroke, producing output power.
A steam turbine produces power with pressurized steam expanding to high velocity, and impinging on turbine blades which produce rotational output power. A steam turbine can be considered similar to a windmill, although steam turbines typicaly rotate much faster, and often have many stages of steam expansion within a single machine.

Previously Viewed. Unanswered Questions. Math and Arithmetic. Units of Measure. How do you convert steam usage in tonnes to Kwh of gas consumed? Wiki User You have to consult tables which give the properties of water and steam commonly called Steam Tables.
You have to calculate the total enthalpy of the steam as delivered, and subtract the enthalpy of the returned condensate if returned or of the water as it enters the boiler. In modern steam tables this will be in kilojoules per kilogram. You can multiply by mass to get total energy. Various organizations have published steam tables in the past.
The one published by the International Association for the Properties of Water and Steam is the one to use, particularly the formulation for industrial application. There are some free caclulators online which claim compliance to the algorithms, but I can't vouch for any of them. It is not straightforward and you may want the services of a competent steam engineer that leaves me out.
