Description
1
Burning chamber
The part of the burner that is inside the boiler and where pellets are burnt.
2
Burner body
The part of the burner that is outside the boiler.
3
User interface
Screen, navigation buttons and indication lights. For more information, please see chapter
4.1
4
Control box
Contains inverters, fuses, relays, main controller board etc.
5
Water sprinkler
Sprinkler system will spray water to extinguish the fire in case of back burning. The sprinkler
system is only activated when the temperature of inner auger rises dangerously high.
6
Grate cleaning
motor
Linear motor moves the grates in burning chamber and pushes ash out from burning
chamber. This cleaning cycle is made periodically. The interval between cleaning cycles can
be managed by parameter 48. In each cleaning cycle, the linear motor pulls grates back then
pushes the grates completely out and then pulls the grates on the half way. The linear motor
has 75mm stroke and end switches for stop. Linear motor current limit can be set by
parameter 47. There is also fuse F10 installed on the controller board (board version BBB
v2.1)
7
Igniter
Igniter´s purpose is to ignite loaded fuel making the burning process start. Igniter is installed
on the burner together with igniter holding pipe. PV1000agri has total four igniters.
8
Brick temperature
sensor
A sensor to adjust burner start up speed according to temperature rise. Brick temperature
rise speed must be controlled to extend its lifetime.
9
Cleaning hatch
Hatch below burning chamber to ease the removal of ash under grates.
10
Grates support
frame
Holds moving and stationary grates in correct position.
11
Grates
Cast iron grates form fire bed and distribute combustion air through holes in grates. Some of
the grates are moving to periodically clean the burning chamber.
12
Fire bricks
Heat resistant bricks that cover the burning chamber. Bricks are necessary for proper airflow
and combustion.
13
Flame sensor
Photocell´s purpose is to recognize flame in the burning chamber.
14
Level sensor
Optical fuel level sensors recognize the fuel level in the vertical pipe. Fuel is recognized when
pellets pass the optical beam between sensors.
15
Combustion air
fans
Left – primary
Right - Secondary
Primary fan delivers main burning air needed for gasification of the fuel. Primary air is also
used to burn the gasified fuel (charcoal) and to ignite the pellets together with igniters.
Secondary fan blows air through burning chamber back-wall and holds burning quality and
optimal flue gas content. If oxygen sensor (optional) is used the secondary fan speed is
regulated by oxygen level in flue gases.
Both fans rotation speed is measured by sensor, installed near the impeller axle. The sensor
is reading magnetic field changes caused by magnet installed on the impeller axle.
16
Controller board
Controller board controls the burner´s burning process, by calculating fuel amount also
feeder and auger work during burning process. Depending on the input signals from the
sensors, controller makes necessary changes to the output states to maximize burning
efficiency. Controller has a single control board.
17
GSM modem
(optional)
A GSM modem enables burner to send SMS messages with various information of burner´s
operating states (errors). GSM modem is located in controller unit. More information in
chapter 5.1
18
Internal feeder
motors
Internal feeders are used to deliver correct amount of fuel into burning chamber. Delivered
fuel amount is regulated by periodical work of feeder gear motors.
24V DC motors are supplied from backup battery to empty feeder tubes in case of power
failure.
19
Battery
When there is no power from the main power supply then the burner is operating on battery
power. PV1000 uses two 12V 3,4 Ah batteries. Because the battery is a safety element, the
