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

"Burners of the power type use a fan to supply and control combustion air". Depending on ASHRAE Handbook & Product Directory, a "power burner" could be of the natural draft(natural-draft power burner) or forced-draft type(forced-draft power burner).  10, record 1, English, - forced%20draft%20burner

On peut également classer les brûleurs [à combustibles liquides] suivant le mode d'apport de l'air de combustion. Ils sont dits: - à tirage naturel [...]. - à apport d'air si l'air est amené par des dispositifs mécaniques [...] soit refoulants, soit aspirants. - à tirage forcé si l'air de combustion aspiré par le brûleur met la chambre de combustion du générateur en surpression par rapport à l'atmosphère (foyer surpressé).  7, record 1, French, - br%C3%BBleur%20%C3%A0%20air%20souffl%C3%A9

A period of time after the run period during which the burner motor (blower or fan) continues to run, driving all the products of combustion and any unburned fuel from the combustion chamber, and supplying air to burn fuel being purged from the fuel line downstream from the safety shutoff valve.  1, record 2, English, - postpurge

Record number: 2, Textual support number: 1 CONT

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 2, English, - postpurge

Forced Air Wood Furnaces. Central wood-burning furnaces are controlled by a wall mounted thermostat in the living area. Temperature and fan controls are the same as those found on oil and gas furnaces. Unlike room heaters, which produce a steady heat output by periodic manual adjustments of the draft control, most wood furnaces operate in cycles. A cycle starts with the thermostat sensing that heat is needed in the room where it is located. It signals the furnace control system which opens the combustion air damper and a hot fire develops. When the air inside the furnace's sheet metal casing gets hot, a preset fan control starts the circulating blower and the warm air is moved through the ducts to all areas of the house.  1, record 3, English, - forced%20air%20wood%20furnace
