Boiler 100-470 Prexterm 125

Prexterm 125
DESCRIPTION
Referring to the classical design solution based
for alternating the direction of the flame, the boiler PREXTHERM offers new standards
performance due to a sharp increase in the dimensions of furnaces
and exchange surface. The system of "total isolation" and
corresponding to the requirements of the most modern instrumentation installation
They raise wtdajność boiler.
HIGH PERFORMANCE
The flame reaches the deepest parts of the furnace due to increased
pressure that is necessary for boilers with high thermal exchange
Then znienia its course and returns to the forehead, where very high
at dopalają not yet burnt particles. Exchange
Convection takes place through smooth tubes provided with the tabs
of refractory steel, and provides heat to amount of 92-93% efficiency
combustion at nominal load. Exhaust system by
concentric rings (concentric) allows for smooth transition
kieruku exhaust and even distribution of heat load,
thereby reducing the total stress in the heat exchanger.
WATER CIRCULATION
The water circulation inside the body is controlled. particular type
Circulation returns colder water until the lowest part of the boiler,
thus avoiding heat shock, which have been adversely tube furnace and
especially in the start-up phase. Circulation is conceived to water
He kept a higher temperature where it may occur
sludge in the case of inadequate water and where there is
the smallest heat load and thus the risk of stone
sedimentary.
INSTRUMENTATION
Besides the standard instrumentation, a second thermostat regulates the flame on
the first stage of the burner and optimizing its work in periods
minimum load of the boiler. Two operating hours counters allow
check the wear of the boiler and fuel consumption. In addition, the series
PREXTHERM is prepared to install a temperature controller.
INSULATION
The shell is insulated with a thick layer of mineral wool
High density. The front door and the rear flue gas chamber are also
insulated by covering with wool and separated by a layer of powitrza
(In the case of boilers PREXTHERM 100-470, or by a fleece layer
mineral boilers PREXTHERM 500-2000).
