1. TECHNICAL ESCRIPTION
Thermal boilers VI AS are designed for combustion of dry wood materials, using sawdust to wood logs
according to the dimension of gasification chamber, with maximum diameter of 20 cm. Sawdust,
woodchips, splinters and cuttings must be burn together with wood logs. Thermal boiler VI AS 29 UD is
designed to burn brown coal. It is possible to use dry wooden material as a substitute fuel.
Boilers are welded from 4 – 6 mm steel sheets. Inner boiler sheets, which are in contact with boiler waste
gases are 6 mm thick, others are made of 4 mm steel.
Heat exchanger is welded from steel pipes, 57x4,5 mm. Exterior boiler panels are made of 0,8 mm sheet.
Thermal insulation of the boiler is made of isolation material, NOBASIL 20 and 50 mm thickness.
Combustion gases are lead through steel boiler neck to the chimney.
The boiler space consists of combustion chamber, where fuel is dried and gasified. Then accrued gas gets
through fireproof /concrete, cast iron / nozzle into combustion chamber, where it burns with help of
secondary air. Flue gases are intensively cooled in the exchanger. Unburned waste must be removed from
combustion chamber. The boiler has a light up damper controlled by rod at the front of the boiler.
In order, the boiler complies with the requirements for non-demanding operation it is equiped with AK4000
control located on the top panel of the boiler. Designed system allows very effective combustion of various
kinds of fuel. Control AK4000 with graphical display in basic configuration allows :
to control temperature of heated water in range 70 - 85°C
continuous and automatic control of fan according to required output and kind of fuel
connnect and control discharge fan
connect and cotrol circulation pump
to connect gases thermometer
connect room thermostat (room temperature regulator is voltage free )
to connect extended regulation (Expander AK 4000) via BH BUS
to connect module AK 4000M data back-up, followed by PC evaluation
graphical scheme indicating hydraulic boiler connection as requested
real time set
Configuration VI AS Lambda Control offers :
to control the servo flap of primary and secondary air based on data received from lambda sensor
oxygen level reading
during power cut, AA battery types will close servo-operated flap and prevent boiler from natural
burning of boiler without chimney draught
The boilers are equipped with thermal fuse STB, which ensures disconnection of the boiler fan, if
overheated above 100°C and exchanger safety to prevent boiler against overheating by standards, STN
EN 303-5: 2012. Producer recommends to purchase safety valve TS 131 ¾“ and install to exchanger to
avoid overheating.
