new truck build

Looks great Greg.

How long will it take them to finish the truck?
 
Jim your the burner guru how many btu would I need for a heat rise of 140 to 150 if I'm pushing 16 gpm. If I put a burner on It would only be one that can handle both machines.


Just to let you know, I am not an expert on boilers. I just have some formulas due to us custom building our equipment to high specs than whats out there in order for us to do specialized cleaning in Parking Garage Cleaning.

At the time we built our equipment, there was really nothing out there that would hit 300 degrees under a full load of 6 to 12 GPMs for Parking Garage Cleaning.


Here is the formula that we used:


First, convert GPM to GPH

Next, Determine the pounds of water per hour by multiplying (XXXXX) GPH x 8.35 LBS. per Gallon

Remember, It takes 1 BTU to raise 1 pound of water , one degree F.

Most Pressure washers operate 75% efficiency. Therefore you must divide the BTU by 75%. I actually felt 68% is a more true number. ( 32% heat loss). and if your burners are a few years old or have more than 1,000 hours on them, then lower the percentage by 5 to 7% more.

There is the formula.


Glad to help.

Who said Triginometry would'nt come in handy..Now it all makes sense, since you put it that way :confused: :p
 
Thanks jim thats good info. do you know of a good stand alone burner thats a true 666000 btu's. I've always had vertical burners but i would switch to horizontal if i had to. I would like to kept the total height of the truck below 7 1/2 ft.

I know of one ;) . I will PM you some info.
 
I just got my truck back from the fabricator and started putting some things on it. I will post some more pics as it progresses.

Hey Greg, I noticed that you have bulkhead fittings on the tank legs. How did you get the tighten the nut on the inside of the tank? By the way, that flatbed looks awesome. Real Nice.
 
Good God, I guess I need to lose some weight,:D or just put my 8 year old daughter in there to tighten the nut.
 
Sorry I hit the submit button to many times, whoops.
 
I got a few more things done with the truck. 225 gal tank and hose reel for the chem pump. all i have left is burners.
