3.3. Cleaning
Internal construction of Biomaster boiler allows separation of combustion chamber
and exchanger part. The main part of a heat exchange surface are pipes (smoke
tubes), inside of which are located spiral-shaped turbulators. They improve the
efficiency of heat exchange and allows to conduct automatic process of cleaning
exchange surface. The process includes regular back-and-forth motion of turbulators,
which remove a layer of ash on exchange surfaces (11, Fig. 1.4.2). Typically, boiler is
equipped with smoke tubes cleaning device and ash container. Ash should be
removed when the flame is low and the blower is deactivated. To save fuel, the inside
chambers of the boiler and the spaces between the elements of the combustion
chamber should be kept clean.
The ash drawer cannot be fully filled.
The boiler should be cleaned at least once a month with the use of publicly
available sanitation equipment like brushes and scraper.
Decrease in the chimney draught signals necessary cleaning. Lack of air makes
the boiler to return smoke. During cleaning, ventilate the boiler room well.
S
weep the boiler only when it is extinguished.
In the case of large dirt residue it is allowed to use chemicals which remove
exhaust carbon, but only those which are regular commercial products (those which
have safety signs).
The flue gases from a clogged chimney are dangerous. The chimney and
flue should be kept clean; they should be cleaned before every heating
season.
It is forbidden to turn on a device without ash container.
3.4. Programmed boiler shut down
Shutdown occurs by stopping the fuel supply to the boiler that is by turning off the
controller. The cool down time is roughly the same as the ignition time. After the
heating season is over, the boiler must be cleaned and all doors opened. Remove
the ash, clean the boiler. Do not drain the circulation water.
