|Fuel Gas||Max Temperature||Characteristics|
|Acetylene||3300°F||Highest flame temperature. Many torch options available. Produces carbon soot and cannot be used with Platinum. Must be purchased from a welding/gas supplier. Not sold in most hardware stores.|
|Propane||2800°F||Less expensive than acetylene and more readily available. Clean burning. Can be purchased in small disposable cylinders. Lower flame temperature than acetylene. Should not be stored indoors.|
|Hydrogen||2650°F||Relatively high flame temperature. Perfect for casting platinum because it’s clean burning. Expensive and only available from specialty suppliers.|
|MAPP®||2900°F||Combination of liquefied petroleum gas and methylacetylene-propadiene. Readily available in small disposable cylinders. Clean burning and high temperature.|
|Natural Gas||2750°F||Lower temperature. Safe and cost effective if you already have a natural gas hookup, but requires a professional to install.|
|Butane||1760°F||Affordable and readily available. Small containers means it’s very portable. Low temperature.|
I've had mine I luckily bought brand new never ran about 7 years ago and quickly discovered the short comings of a small water Tank. So keeping pressure up for the Butane to provide enough heat I got into a conversation with a Electrical Engineer retired in the UK that also had two of the Aristo Mikados Live Steam. We modified ours very simply. Running 16 volts track power he engineered a simple "heater" out of a resister installed in the water tank and a thermal shut off switch which regulated the water tank to about 120 degrees and a on/off Switch hidden in the Tender. We both installed his system. Simply turn on track power and Heat switch. Water stays hot and steady temperature keeping Butane warm and plenty of flame for the burner now. You need to of course add some pickups to your Tenders wheels for power but I am sure you experienced Modelers have all done that before. I run mine easily at 60 psi pulling my heavy weight Aristo Passenger cars easily on Butane with out it stopping to build pressure in the past. Simple System and yes the Aristo Live Stem Mikados can be ran on a powered track. I rarely Post being a very quiet Live Steam Locomotive and Electric Locomotive Collector but the Mikado among my 30+ Locomotives is a real pleasure to run. The Polk Family were they still in business today I'm sure would have dev eloped more fantastic Live Steam versions... Kenbobstrong: I miss spoke, meant the Mikato. I understand the Aristo was made of a heat resistant plastic, a great innovation, very sorry they are not around any more, can only imagine what the Polk's would have introduced to our hobby. I was wondering why lotsasteam indicated he didn't appear to get more heat with Propane. My research, with the help of others, showed the Aristo doesn't have the ability to allow MORE air to enter the burner, which propane needs. The quest for more heat has been ongoing, hence the radiant burner, ceramic burner and use of alcohol and coal for fuel.
