CONSTrUCTION
The ecological water-heating boilers
PYROTHERM
are created for pyrolitic burning of logs, and, after the installation of the
appropriate container, for pellets as well.
The boiler body is made of steel sheet iron that is 3-6 cm thick.
It consists of a fuel compartment that, it its lower part, has a ceramic nozzle with a longitudinal opening, through which the
gases formed after burning pass.
Below is the burning section, where the wooden gases burn on a ceramic hearth.
The nozzle and the hearth are made of high quality ceramic material with working temperature up to 140 degrees.
The upper part of the body has an opening that serves as an entrance and exit to the serpentine, which acts as a coolant
to prevent the boiler from overheating.
The body itself is isolated from the outside with mineral wadding, placed under the lids of the boiler.
The rear part of the boiler body has a vertical canal for the smoke; the upper part of this canal holds the ignition valve.
The rear part of the collective canal has a formed smoke pipe that connects with the chimney.
There is another canal in the rear part of the boiler, which carries the primary and secondary airflows, and a fan with a vent.
The primary and secondary airflows are pre-heated to reach a high temperature.
At the front upper part of the boiler is the door for fuel loading, and the lower part has door for cleaning the ashes.
When pellets are used, this door is to be replaced with a door for installing the pellet burner.
The upper part of the front lid contains the control panel, and on the right side of this lid is the handle for the igni-
tion valve.
The control panel contains: a luminous net switch that turns the boiler on; a boiler thermostat which regulates the tempe-
rature at the exit of the boiler; thermo- and manometers that measure the temperature and pressure of the of the water
at the exit of the boiler; thermostat for smoke gases – controls the temperatures of gases at the boiler’s exit; signal lamp
“ALARM” that lights when there is a problem with the boiler; an emergency thermostat – switches the boiler off when the
water temperature exceeds 95 degrees Celsius; and a safety fuse – protects from a short circuit and overloading.
The rear part of the panel has a joint that connects the pellet burner with the boiler, and a switch that chooses a mode of
operation.
The burning process of the pyrolysis goes through the following stages: when there are live coals at the bottom of the
burning compartment, the logs that are on top of it are dried from above downwards by the pre-heated primary airflow
supplied by the fan, thus causing a pyrolitic distillation of all flammable ingredients.
The formed wooden gas, after mixing with the preheated secondary airflow, burns in the nozzle and the burning compart-
ment at very high temperature (over 100 degrees Celsius).
Such temperature ensures the burning of the fuel with almost no remains and a minimal content of harmful elements in
the exhaust gases.
If the burning process goes as planned, the ash can be cleaned once in 5 days and be used as a fertilizer.
The operation and fine-tuning of the regimes of the pellet burner are described in detail in a separate manual for installation
and exploitation.
