Macmet,
If you have constant air at any firing rate then you must consider that you have to heat that excess air up - so part of you btu power from what ever fuel you use will go to heat the excess air (if in a closed furnace) - in other words you only need so much Theroetical air to burn a...
Avimech - I suggest you try Maxon for an Oven-Pak Burner and you should start your own thread.
Hjmin -
A fan has a certain static pressure that it is designed for if you are firing in to a smaller area - your pressure drop could be high for the air you are trying to push through - check for...
Livingston,
Assuming that you are burning Gas or light oil and this burner fires with 100% air through the burner and you are firing with 10 to 20% excess air - this should normally not be a problem for a few percent increase in capacity. That is if you are firing into the same system. You...
fvincent,
Who designed the water U tube arrangement - sounds ancient and in sorry need of replacement.
Without knowing alot about the installation and the details, I need more info - do you have a combustion fan or 8 combustion fans and what about an exhaust fan? Also how many Btu/hr are we...
TThehammer,
When you install any gas appliance the lines should be tested to determine if they leak. Several ways of checking this - pressure test for 1 hour at 1.5 times flowing pressure - (be sure to isolate any device that can be damaged by excessive pressure) or use s a very soapy water...
rsbuck,
psafety has it right - the high gas pressure switch is alays downstream of the shut-off vvalves (Maxons or other) and the Low gas is before them. When the gas is flowing the regulator is open to maintain pressure - when the burner shuts down - Moxon valvces close but the pressure...
Leverage,
I posted a similar post over a year ago and did not get many satisfactory answers. We are currently converting 4 small WT to 3 FT - let you know in a few months.
I have heard that FT do not last as long and are not good for swings in load. My choice was for WT.
Good Luck

SCouture,
This is not easy say without all the data. When you set a burner up it is important that you keep setup information pressures and flows and temperatures of air and fuel at low fire and high fire. When something goes wrong at least you can revert back to the initial setup.

Ponder,
Consider burning 2 fuels - how do you propose to measure fuel and air flow to know that you have 2% O2 or less. Both fuels will have their own properties, e.g. if your Steady State firing rate is 10 MMBtu/hr - 5 MMBtu/Hr per each fuel what is the stiociometric ratio, of air to fuel -...
Vannic,
Vent lines on gas regulators are to be sized in case the diaphram in the regulator breaks. You want to be able to vent what is upstream of the regulator to a safe outdoor location in case this happens. This is to protect the downstrean equipment - you should also have a high pressure...
Oxidation,
You might need to get a fan rep in this is a big fan - I have seen the result of some big fans coming apart - very dangerous. You should be seeing vibration below 10 mils.
If you are tripping when you start check to make sure that your damper (inlet or outlet) is closed when...
Ibvex,
No. 6 oil Btu content - depending on how accurate you need it to be - the best way is to have a fuel analysis done and then use Perry's Chemical Handbook to calculate BTU's (if the analysis did not state it) or from Handbooks :
No.6 Oil Gross Heating value
18,126 Btu/Lb
153,120 Btu/Gal

Sorry the holidays and have been tied up.
m = Mass flow (lb/hr) of media being heated
cp = Specific heat of media being heated
dt = the temperature increase of the media
For you example 35lb/hr air at cp = 0.24 and from Tinitial=60F to Tfinal = 150F (eg. dt = 150-60 = 90F I...
