imhave a question that I have Ben researching
How do you measure heat exchanger heat???
Propane is 80-240 btu' per hour
Kerosene heater is 230-350 Btu...that is British thermal units.
This is my attempt to measure hx's!!!!
Diesel and gas have 125-135 btu per gallon
A small engine is 40% efficient....30% cooled and 30% exhausted.
My engine 33 hp burns about 2 gallons per hour
That means it uses 100 btu' and exhausts 75 btu per hour.
The question I have is how ificient are heat exchangers at converting heat.??
I believe fuel heaters are 85-95% efficient at converting btu's.
I am guessing hx's may be the same or a little bit less.????
If my calculation is correct it would be at best 80 btu per hour more like the small little giant propane????
I would prefer feedback from anyone as I am not a physicist just doing research.
