7.2. FIRING UP A BOILER
Firing up a fuel in boiler should be started when checked if heating installation is filled
with water, and water is not frozen. It should also be checked, if water is not leaking
through thread fittings on boiler. Do not forget to heat the chimney prior to the firs
startup.
Before firing up a boiler it is necessary to close furnace and ash box door, than on
the surface of the fine coal already placed in the furnace (filled up to the edge of the
chute) put pieces of crumpled paper, and then pieces of wood on top of it. Fire it
up, close chute door, switch on the controller and set the required temperature.
NOTE: Person operating the boiler should know that some of boiler’s
areas are hot, therefore protective gloves should be worn! The same applies
to protective goggles.
Fuel combustion process is regulated by controller, as well as the process of
forced air delivery into combustion chamber. Next fuel application takes place
provided previously introduced fuel is completely burned out and furnace is
cleaned.
During fire up process the boiler should be monitored until it gets
feeding water temperature of 45°C. It is import ant, as varying fuel quality
may cause the boiler to go out.
In case of fire in boiler went out during fire up operation a furnace must be
cleaned, boiler’s should be ventilated and fire up should start again.
During the process a smoking or sweating of boiler may occur. Once boiler and
chimney duct get hot, those adverse phenomena should go away.
