BTU's per Gallon ? Jerry Campbell 11-19-02  
Someone told me that propane puts out about 100,000 btu's per gallon. I don't know if this is true but I'm wondering what the difference in fuel consumption
would be between diesel and propane for heating my bus. I see marine diesel heaters that burn 1 to 3 gallons per day, 5 to 15,000 btu's. I would like to stay away from propane if at all possible. We spend the winter camping on the beach in Mexico and there have been many times you could not get propane because it was freezing in the mountains and there was none left for the warmer places.
So far I have replaced all the windows with sheet metal and insulated the walls. Now its time to take the money and run. I hope to drive it down next year so I have until the spring to figure it out, then the design phase ends and the work begins.
Thanks
Jerry

The btu does vary some, but the Propane is pretty consistent at 91,500
Diesel is about 140,000btu don't forget to discount for efficiency loss of the exhaust. Suburbans can be 65%, good diesel fired can be much higher.
Calculate Natural Gas Usage Robert Allen 4-25-07  
What formula would I use to calculate the amount of natural gas that would be required to raise the temperature of 2000 gallons of water from 72 degrees to 150 degrees?
Re: BTU's calculation or formulas Jim Mckenty 2-2-03  
Whatis the formula or formulas for the calculation of BTU's.
what I have is a hot oil boiler what I want to know is what are the btu's delivered.
so far what I know is that the supply pipes temp. is 190 deg. C and the return pipe is 88 deg. C what else do I need to calculate the BTU's delivered eg. oil flow fan speed cfm of the fan the size of the pump that pumps the oil the boil is 3.300,000 btuh.
the regularor valve is open at 40% the oil psi. is 40 the pipe size is 3"

can you also supply an example or freeware soft ware to do this.
the reason I would like to know how to do this to prove a point. that an air compresser has at 80 psi has 10 cfm and another has 80 psi and 35cfm. the differance is the amount of energy delivered.I would like to show the same thing when you change damper settings or change the air flow the amount of energy changes BUT you can also have the same temp.

can you help

BTU'S PER CU FEET KIM 4-19-05  
I AHVE CONVERTED MY GARAGE INTO A 2 STORY LOFT. 400 SQ FEET WITH 14 FOOT CEILING. HOW MANY BTUS INAN AIRCONDITIONER TO COOL THE ROOM?

Re: BTU's per Gallon ? Gary 2-8-04  
OK, let's start at the beginning. Whoever put the formula for KWH & BTU's is wrong. There are 3414 BTU's in a KWH, not 3.414 (that's a watt). Figuring the btu's needed to cool a computer room varies greatly by the amount of heat produced. There are 12,000 btu's per ton. You need to allow for extra load and latent heat loss (without getting too technical. So, take the total btu's, multiply by.33 then add this number to the total btu's and divide by 12,000. This will give you the rough tonnage needed to cool the space. Computer rooms are very tricky to cool. The varing load on each system CAN change the required load. Which if you figure for the maximum load, it can leave you with a frozen coil from lack heat.

Figuring the wattage of each piece of equipment is fairly simple. Take the amperage times the volts to get watts (P=IxE). The average btu's for a person is 600 btu's.

A 1200sq.ft house should have a 2.5 ton A/C.

NAB, how many pounds of steam per hour do the boilers produce? NOT PSI, pounds! It is stamped on the boiler someplace.

Lets try this again.

Gasoline 115,000 BTU/gallon
Diesel 128,400 BTU/gallon
Propane 84,500 BTU/gallon

You need to burn 128,400/84,500 = 1.52 gallons of propane to produce the same amount of heat in 1 gallon of diesel.

As a reality check.
A heater that creates 15,000 BTU/hour and runs non stop for 24 hours
would burn
15,000*24 hours/128,400BTU/gal =2.8 gallons of fuel.

Thanks in advanced.
Re: BTU's calculation or formulas NAB 8-8-03  
I would like to calculate the Natural gas Consumption in a steam boiler.

We do have two boilers the first generate steam in 150 psi the second 50 psi. the return condensate quantity in known.

How do I calculate
1- The gas consumption for each boiler?
2- The heat btu/h for each boiler?

Thanks.

Best Regards

Can you please tell me a quick way of calculating roughly how many btus = radiator
Re: BTU's per Gallon of gasoline Mitch 11-11-07  
87 89 and 91 octane all have the same BTU per gallon. There is no more energy in 91 octane than in 87 octane.
91 octane burns slower than 87 octane.
You want your fuel to burn as the piston is pushing down. You don't want it to explode and knock the piston or hear engine knocking.
