In traditional combustion mode on a water grate located under retort, boiler
functions on operation an air draft regulator and thermometer.
Combustion in the automatic mode:
The boiler functions based on the set composed of:
screw fuel feeder driven by motoreducer
grateless, self-cleaning furnace in the from on the cast iron retort of goblet
shape
fan blowing the air into the chamber – retort
electronic temperature controller.
The fuel for combustion process is transported by means of a screw feeder from the
fuel hopper placed by the side of boiler.
All processes leading to fuel combustion together with the air delivered by blow-in
fan take place in the iron cast retort. Above the coal burner an iron cast deflector in
placed. The deflector radiator plate deflecting heat radiation onto a glow in order to
make combustible gases be burner completely and distribute fumes into the heat
exchanger uniformly. The cinder which has been formed in the final phase of
combustion process in moving towards the rim of the retort, and then drop down into
an ash pan chamber. For easier maintenance the chamber is provided with a drawer
pullout type.
Due to its efficiency, the combustion chamber burns such a quantity of fuel, which is
necessary to obtain the temperature set on the controller. The controller constantly
measures the temperature of water boiler. Depending on the results, it controls fuel
feeder and ventilator. At the same time the controller operates a circulation pump
(provided a heating installation is equipped with such pump). Detailed design,
functioning and operation description of the controller is attached to this controller
manual.
The boiler’s advantage, is a simple operation relaying on periodic coal bunker
refueling (the fuel bunker) and cinder removing from the ash drawer with no
requirement to stop the boiler. Once boiler is fired up, it does not call for further
service, and its operation may be practically continuous in the entire heating season.
Boiler may be also use beyond heating season in the configuration with hot utility
water boiler.
Combustion in the “traditional” mode:
Additionally, the boiler has furnace with water grate ( under a retort), what
makes it adapted for “traditional combustion” mode. In this mode, boiler takes
advantage of natural draught of gases, due to that there is no need to supply
electric power. Combustion process can be regulated by means of adjusting
knob controlling the air delivery. This knob is placed in the air intake dosage flap
(pos. 14), or by means of air draught regulator (pos. 15).
Temperature of water in a boiler, may be red on thermometer (pos. 23). Such
solution enables functioning of boiler in situation when electric power supply is
