Anderson Thermal Solutions – VFC86 Burner Operation Manual

combustion chamber is purged. If it is ignited at a low temperature, it needs to be replaced

with 5 times the volume of the combustion chamber to avoid explosion.

However, it is not necessary to purge when the temperature is higher than 750°C. Air pipe

or gas pipe connected with burner should be tight enough with no leakage, also the

periodically check air or fuel nozzles of the burners to prevent to be blocked by dust, slag

or other materials.

ATTENTION：DANGER OF BEEN BURNT

When burner in operation, combustion is severe, so the burner must be fixed. Hoses or

cables in area of the combustion system must be suitable for high temperature, to prevent

high temperature failure or cause safety accidents. Burners should be periodically

inspected and cleaned. Copper wire brush may be used, if necessary, to clean burner head.

The burner system should be checked twice a year for safety operation.

Burner commissioning shall take care of ignition position, minimum and maximum output

position. Following interlocks will cause emergency stop, including gas low pressure, high

pressure or low combustion air pressure, as well as emergency stop is trigged, the main

power is out, UV signal failure or kiln safety conditions (such as high temperature limit, flue

system opening, etc.) will cause the burner lockout. Users need to know the maintenance

interval recommended by the manufacturer and the interval specified by national laws,

whichever is shorter.
