A two phase furnace includes 2 types of heat. Usually it is composed of an electric heat pump and also a nat. gas/ propane heat source when the temperature drops below a set range. The reason they use these is because heat pumps are very efficient when there's not a large temperature change required, but they're efficiency drops dramatically when the outside temperature (or ground temperature) drops below freezing.
The only other two-phase furnace would be a two-phase electric (as opposed to a three-phase electrical furnace.) But I don't think you're asking about 2 vs 3 phase electrical furnace systems... Those are quite rare.

It means the Phase anlge is not matching with control board phase angle or more capacitor connected in the furnace line. we have to Remove some tank capacitor.
Furnace has two syllables. Furn-ace.
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.
All words have at least one syllable. Furnace has two. Fur-nace.
A cupola furnace is not the same as a crucible furnace. A cupola furnace is a type of melting furnace used mainly for iron melting, while a crucible furnace is a type of melting furnace that uses a ceramic or graphite crucible to contain the molten metal. The names reflect the different structures and functions of the two types of furnaces.
From one phase to the next you should see 208 Volts.From any phase to ground you should see 121 Volts.AnswerYou are very unlikely to come across a two-phase machine, as two-phase a.c. systems are archaic. A two-phase system has two phase voltages that are 90 degrees out of phase with each other, and was used many years' ago. These days, you have either single phase or three phase. So it's probably safe to say that there are no two-phase motors about, these days!
Two raw materials that are used in a Cupola furnace include rocks and briquettes. The cupola is a vertical furnace that is similar to blastfurnaces.
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
A two-phase* system is archaic, and has been completely superceded by three-phase systems, so there is no demand for two-phase induction motors. (*A two-phase generator has two phase windings, displaced from each other by 90 degrees.)
To answer this question call a furnace person and ask him your question okay because nobody knows this. Stupid people! P.S. Why do you want to know this anyway?
