An advantage of a boiler is its simple operation in form of periodic replenish-
ment of fuel in the tank and removing ash from the ash drawer without a need to
put the furnace off. After firing, the boiler does not require a continuous operation,
and it can be used, generally, in a continuous mode during the heating season
(excluding breaks for periodical cleaning and repairs). Systematically performed
maintenance and cleaning ensures long and trouble-free operation of the boiler.
A boiler room with a solid fuel boiler is not maintenance-free and requ-
ires periodic monitoring. During boiler operation certain daily control activi-
ties must be performed, to prevent emergency situations.
BOILER DESIGN:
With the boiler structure based on three-pass layout of a flue gas duct in the
exchanger with ceramic panels, flue gas heat is fully recovered and used in a
water-based central heating system. Also the upper part of the furnace chamber
is closed with a water jacket.
Flue gases are directed to a stack through a flue located in the back part of
the boiler. A flue gas damper is installed in the flue, which can reduce the flue gas
flow when it becomes too strong (regulation). A clean out openings are located
on the side of the flue pipe. The flue pipe is fitted with the exhaust gas temperatu-
