THE RAVELLI GROUP HAS NO SECRETS
The design shows how a pellet stove works, highlighting its main components.
|
When the stove is switched on, the flame lights following the combined action of three elements:
1. air, that enters the stove via a primary air input duct (19) and reaches the burner (17)
2. the pellet, that is taken from the hopper (3) and poured into the burner (17) via the screw
3. the resistance, that activates combustion as it heats up
Combustion generates smoke which, coming into contact with the exchanger (5), releases all its heat. The released heat is then conveyed to the room through the hot air output front grill (10)*. The combustion smoke then continues to circulate through the smoke duct (4), before being expelled by the extractor (6)
The whole mechanism is monitored by an electronic board fitted with a microprocessor which, by means of the various sensors and probes inside the stove, regulates the air flow and feed so as to optimise combustion.
* In this case, since the stove is ducted, the hot air also passes through the rear (2) before being conveyed to the adjacent rooms. The quantity of front and rear air is regulated by a lever (1)
