Power burner [means] a burner in which either gas or air or both are supplied at pressures exceeding, for gas, the line pressure and, for air, atmospheric pressure; this added pressure being applied at the burner. A [power] burner for which air for combustion is supplied by a fan ahead of the appliance is commonly designated as a forced draft burner.  9, record 1, English, - forced%20draft%20burner

The phenomenon which causes a flame to conduct more current in one direction than in the other. It is due to the ionization of air in and around the flame, and to the difference in area of the electrodes in the flame envelope.

The Pactrol CSA provides automatic ignition control and flame supervision for gas burners ... The control provides a short pre-purge period followed by an ignition period, and there is a choice of alternative timings. Flame supervision is by flame rectification, with the option of ultra-violet sensing with the addition of a special UV head. The control will shut-down and provide volatile lock-out following flame-failure or an unsuccessful ignition attempt, and may be reset by interrupting the electrical supply.  3, record 2, English, - flame%20rectification

When the burner is shut off for any reason, the program controller causes the forced draft fan to continue delivering air for a specified time to post-purge the unit of any atomized oil and combustible gases. This post-purge should amount to at least two air changes in the combustion area, gas passages, and breeching.  3, record 3, English, - postpurge

The pressure atomizing forced draft gun burner has a basic construction similar to that of the gun-type burner but this burner is designed to fire into a combustion chamber operated under positive pressure. The combustion process is independent of chimney draft and a draft regulator is not required except when excessively high stack drafts are encountered.  1, record 4, English, - pressure%20atomizing%20forced%20draft%20gun%20burner
