Construction and Operation of the Burner.
ROT-POWER burner is built with connected modules and metal sheet components.
Components exposed to high temperatures are made of stainless and heat resistant steel, other
elements are protected against external factors by galvanic coating or painting. External fuel
feeder (5) is made of stainless steel tube.
The burner consists of the essential elements specified in the schema.
The burner starts the operation by fuel supply from the external tray (9) by an auger feeder (8)
elastically connected with the burner. Then the amount of fuel is supplied by the auger feeder
(12) into the combustion chamber (1). After delivery of the appropriate amount of fuel, the
igniter (13) initiates ignition. After the ignition burner goes into continuous mode in accord-
ance with the specified external parameters. The air necessary for the combustion of the fuel
is supplied by fan (10) via the blower chamber to the combustion chamber, and some portion
of air is also supplied via this chamber to the igniter. The air intake to the burner is located in
the bottom part. During the operation, drive (11) causes the cyclic rotation of the of the com-
bustion chamber including the outer tube (2). The frequency of rotation is adjustable. Com-
bustion products move to the front of the burner and exit it, then accumulate in the ash pan of
the connected central heating boiler or other boiler adapted to work with the burner.
Burner is fully automatic and adjustable. Fuel is automatically drawn from the tray,
depending on the demand for thermal power. In the event of exceeding set limits burner goes
into standby mode. The transition from standby mode to operating mode is also automatic, the
burner goes into ignition mode and then again in the continuous mode. The intake air quantity
is closely related to the amount of fuel delivered for optimum combustion and does not cause
an excessive cooling of the combustion chamber. Operation of the burner in based on provid-
ing an appropriate amount of fuel and on periodic removal of combustion products, i.e. ash
from the boiler ash chamber.
The burner is equipped with security features that protect it and the central heating
boiler against overheating and other risks that may arise during the operation. The first is a
photocell, which is responsible for detecting the presence of the flame. When the flame is
absent, the burner switches its ignition mode, i.e. a small amount of fuel is provided and the
igniter is triggered; the firing mode lasts for 2 minutes, when the ignition fails - the operation
is repeated 3 times. After an unsuccessful ignition, the controller will display alarm message,
further work is not possible until the error is cleared. The second safety element is a tempera-
ture sensor placed in the blower chamber, which breaks fuel supply from the main feeder in
case of igniting the fuel dose inside the auger feeder that supplies fuel to the combustion
