Waste oil piping

hot_rod Member Posts: 21,842
a shot at a carwash/ jiffy lube that wants to replace several natural gas boilers with waste oil boilers. Keeping one NG boiler for backup.

Anybody know which NFPA codebook covers undergroung oil lines?

On this project the wash and lube buildings are about 100 feet apart. They would need to run some lines for the oil between the buildings. Is this an application for a double walled tube?
Thanks for any info on lines, or waste oil in general.

    Hot Rod, That information can be found in NFPA-31 For oil burning equipment.

    Hope that helps.

    Hot Rod, I was a Clean Burn dealer,

    And if I was you check with maker of unit you are planning on using. That is a long run for waste oil. Now add cold weather and oil will thicken up, you might find that you will need some lines way bigger than say 1/2 inch. You even might have to have a holding tank close to boilers and a transfer pump from main tank to keep your holding tank full. It does sound like you do have a great use for that waste oil and can save allot of money to heat up water. P.S. try to get their tech manual to learn more. The type of burner that burns waste oil while similar to an oil burner is nothing like one. Also annual service is by hours and may require service every two months. And last you need to think back-up system incase of fuel problems or parts, which most supply houses, DON’T carry. Hope this helps John@Reliable

    Thanks, gentlemen

    I'll order up that NFPA book. I have a Clean Burn 350 on order for a small 10,000 foot diesel shop, should be here this week.

    For the carwash it will take 4- 350,000 Clean Burns, Figured on a 1" oil line between the buildings in a trench with a couple pex lines for warmth, if needed. I had also planed on a small tank next to the boiler for transfer from the large waste tank, in the lube building, with a transfer pump and level and safety system. I'll probably sub that portion to a local petroleum company.

    The factory has offered to help on these first two installs and set ups. Were you happy with the Clean Burn product and support?

    Waste Oil Piping

    Hot Rod, I would try NFPA 30, Flammable & Combustible Liquids Code. That covers most piping,and what most be done underground.

    Hot Rod,

    I was very pleased with them. But I found while theirs money to be made with service and installs you must also do allot of traveling. I have a friend who only does waste oil systems and they have 4 trucks for service that can do 4to6 hundred miles a day per truck when busy and that may only be 3 calls each. I decided to stay with #2 and do 10 calls a day with only 100 miles.
    Hot rod, are you using a bench tank set-up for the diesel shop? If not check it out. Will make the job go quick and safe. John@Reliable

    Clean Burn

    I am happy with CB, they are the one to use. However, I am just not comfortable with HR's underground line system.....I see problems.
