2. PRODUCT DESCRIPTION
The BURNiT Pell pellet burner for hot
water boilers is designed to burn only
and exclusively wood pellets and it is
intended to heat up heang boilers. The
built-in control unit, automac cleaning
system and internal pellet auger ensure
the automated operaon of the burner
and opmal burning of the fuel.
2.1.Design.
The burner is made of high-quality
stainless steel able to withstand
temperatures of up to 1150°С. The
burner must be installed on a heang
boiler.
The burner consists of two parts:
combuson chamber tube and
external tube with sheet metal mantle.
Longitudinally, under the housing, there
are blow chamber, fuel ignion heater,
fan and power supply. On the upper part
of the burner there is a feeder chute
to which the pellet auger is aached.
The housing of the burner has been
designed to meet all regulatory safety
requirements (no sharp or protruding
elements) with operang temperature
not exceeding 50 °C.
The combuson chamber consists of two
tubes:
Ember resistant steel tube inside the
burner with holes for air intake along
its enre length, opening for the hot air
from the fuel ignion heater, opening for
photosensor.
Outer stainless steel tube. Between the
two tubes there is a gap which provides
for free circulaon of the air necessary
both for cooling and oxygen supply into
the combuson chamber.
The feeder chute allows 360° rotaon
for its best convenient posioning
when connecng the pellet auger to the
hopper.
