protections conforming the requirements of the standard PN
91/B-02413, applying to protection of open water heating in-
stallations, considering the Regulation of the Minister of Infra-
structure, Journal of Laws of 2009, no. 56, item 461. These boilers are approved for operation in the systems where
working pressure does not exceed 1.5 bars and the highest wa-
ter temperature in the boiler 95°C.
2.2. Design description
2.2.1. Doors
KSR Duo boilers are equipped with upper cleaning doors, fur-
nace doors and ash-pan doors. All doors are equipped with the
glow plates protecting against excessive heating up.
Cleaning doors
Cleaning doors are used for cleaning of convection channels.
Furnace doors
Furnace doors are used for fi ring up and control of combustion
process and for cleaning of heatable surfaces. These doors are
used also for combustion in the boiler using “conventional meth-
od” on the water-cooled grate in case of power stoppage.
Ash-pan doors
Ash-pan doors allows removal of ash formed during the com-
bustion process.
Cleaning hole (cleanout)
Cleaning hole is used for cleaning of convection channels.
2.2.2. Body - water jacket
The water jacket is a space fi lled with heating medium - wa-
ter. The structure is made of steel sheet P265GH for pressure
equipment intended for operation at elevated temperature. The
thickness of a metal sheet of the body from
fl ame side equals to
6 mm. Design solution allows e ffi cient reception of heat by use
return of fl ue gas. Convection channels are located in such way
that they are cleaned through the upper cleaning hole.
2.2.3. Thermal insulation panels
Insulation panels fi xed on the surface of the water casing limits
heat losses to the environment. They are made of aesthetic car-
tridges made of a zinc-plated metal sheet, painted with powder
paint ensuring high anti-corrosion protection. The cartridges are
lined with a mineral wool from the inside, which is used as an
insulation material.
2.2.4. Electronic controller
Microprocessor controller, installed in upper front part of the
boiler allows programming temperature of boiler operation and
programming changes of temperature of its operation at any
time. The controller is also responsible for the so-called blowing
of the furnace chamber. The controller is also equipped with op-
eration control sensor and sensor of emergency boiler shutdown
after exceeding water temperature 95°C. Detailed information
you will
fi nd in the “ User’s manual of microprocessor temperature
controller ”, enclosed in the boiler documentation.
