with acronyms...Q = V A
Q=Flow
V=Velocity
A=Area
Manipulation means you can solve for anything given the other two...
This is used quite often I suspect :-)

Tom Meyer suggested
that we have a place on the site where we could list common industry acronyms, such as SWP and WOG. These often confuse people and I think it's a good idea. Hot Tech Topics would be the perfect place for this.
I could use some help, though. When you have a chance, please email me any acronyms you can think of. I'll compile them and put them in alphabetical order in Hot Tech Topics. Thanks.Retired and loving it.0 -

From the Land of Steam
"A" Dimension= distance water will rise in the drip at the end of the steam main, when there IS left-over steam pressure at the drip
"B" Dimension= distance water will rise in the drip at the end of the steam main, when there is NO left-over steam pressure at the drip (pressure blocked by a trap, water seal, orifice or motorized valve)
BTU- British Thermal Unit, the amount of heat needed to raise 1 pound of water (roughly 1 pint) by 1 degree Fahrenheit.
BTUH- amount of BTUs needed per hour.
EDR= heat output, equivalent direct radiation, measured in square feet. Actual output will vary according to what is being circulated thru the radiator.
LWCO= low water cutoff
MBH- heat input or output, 1,000 BTU per hour. M was used because it is the Roman numeral for 1,000.
Pressure and Flow:
CFH= air or gas flow, cubic feet per hour
CFM= air or gas flow, cubic feet per minute
GPH= liquid flow, gallons per hour, as used on oil burner nozzles and fuel units
GPM= liquid flow, gallons per minute, as used on many types of pumps
PSI= pressure, pounds per square inch, usually "gauge"
PSIA= pressure, pounds per square inch, absolute (disregarding atmospheric pressure)
PSIG= presure, pounds per square inch, gauge (where zero on the gauge is atmospheric pressure)
Boiler Ratings:
Input= amount of heat produced at the burner. Rating is GPH on oil boilers and MBH on gas units.
DOE Heating Capacity or Gross Output= amount of heat delivered to the outlet pipe of the boiler.
Net (or IBR)= amount of heat available at the radiators, after deducting the pick-up factor (heat needed to warm the pipes). This is the rating you use to match the boiler's capacity to the heating load.
AFUE= annual fuel utilization efficiency, a measure of fuel in to heat out over the course of a typical heating season, including any off-cycle losses. Roughly equivalent to Miles per Gallon on a car.

Looking Good
If I might suggest- we should do as good a job as we can to define what these terms mean, for example "BTU- amount of heat needed to raise the temperature of 1 pound of water 1 degree Fahrenheit". This will be a big help to all the budding Wetheads who will use the list!

This may be last on list \"Z\" dimension
"z" dimension = setback of nozzle on beckett burners.
"t" gauge = gauge used to set "z" dimension.
AGA= American Gas Association
CGA= Canadian Gas Association
ASME= American Society of Mechanical Engineers
IBR = Institute of Boiler and Radiator Manufacturers
UL = Underwriters Laboratories
CYA = cover your a~~
John@Reliable0 -
Beckett has a \"Z\" gauge, now
It can be used without pulling the burner out. It fits over the end of the drawer assy and even has a notch to set the electrodes.
You put the gauge on the end, fit it in and adjust the "Z" dimension, then lock it in and pull out the drawer assy. Remove the gauge, and reassemble. Ask for it where you buy your burners.
