Default trying to get more GPH

HI I have an oil fire D&G 2x6 cross flow flat pan system getting roughly 15 gph..Can anybody tell me if I'm wasting my money welding in three cross tubes 20 " long underneath four sections,meaning drilling three 1" holes at each end of the section and welding a 20 " pipe in 1" copper or stainless pipe ...doing the calculations 12- 20" pipes would give me roughly 6.4 more square feet of boiling area..the fire should heat these pipes up..would it work???? I'm not talking about drop tubes that are capped

you may be looking @ unwanted results there.. as the sap will boil in that tube.. but have no where to go.. the gases from the boil will shoot out the ends.. but leave the sugar sand to burn in the tube. If this is the direction you want to go, you would be smarter to put the tube up in to the pan. where the heat is on the inside and your sap is around it. ( like a boiler tube)

so do u think i should use drop tubes..I dont really want tubes in my pans,hard to clean..just thought doing it this way would cheaper and faster at the welding shop..I never thought about what would be going on inside the pipes.Just thought it would move as water boiled out

I've never tried the cross tube idea but I think some on here has. I and others have built the copper drop tubes and they work very well and are accessible for cleaning.

A lot if you put a lot of them in. My steam table pans would evaporate between 2 and 3 times faster with them. It is a combination of a lot more area and the conductivity of the copper that helps. Watch for splashing. They are little geysers.

the sap would boil out and gas would burn the sugar sand...I dont know how that would do that as long as i have sap in the evap.Doesnt the sand travel with the sap threw the different compartments.i think the pipes would be full but boiling..these pipes would be in the sap pan not the syrup pan.the sap should travel threw the different compartments until the finish product...any thoughts??

what if i change the ramp height..Somebody told me if i raise my ramp height it would be more efficient..right now the top of the ramp is 8 1/2 inches from the pan and where the stack is its 5 1/2 inches..thinking about changing the 8 1/2 to 5 inches that way the fire would be hitting the pan heading back to the chimney..stack is 10 inch.I also want to change the nozzle in the burner from 3 1/2 gph to a 2 1/2 gph because its burns so hot its melting and twisting the flapper in the stack..The flapper is made with 1/4" plate steel and would save me some oil..I know the more heat the better but when it starts melting and twisting things its to hot

I think you need to close the gap closer to 1 inch under the flue pan, force the heat up into the raised flues
