MR-750 Venturi Burner
|
|
The MR750 is an affordable and compact Venturi burner suitable for high fire kilns, furnaces, or Raku kilns It features flame retention within a one piece design. It is rated at 77,400 BTUs operating on propane @ 11" WC. Natural gas @ 7" WC produces 78,440 BTUs. Be aware that these BTU figures are based on a set orifice sizes provided by the manufacturer for use at low pressure at the Water Column pressures mentioned above..
If you are using high pressure propane (1 PSI or above), which is a popular choice in some Raku kilns, you will need a nonstandard orifice, and must drill out a blank orifice which will ship with the burner. OR you can purchase the burner with a pre-drilled orifice for natural gas or propane which has been drilled by the manufacturer to the recommended sizes for low pressure. Simply checkmark the option above.

NOTE: The above Btu values can be increased with increases in pressure, but the MR Series of burners may be subject to less efficiencies at pressures greater than 10 psi. It is not recommended to run this burner at any higher pressure.
