3. DESCRIPTION OF THE SYSTEM: A HOT WATER PELLET BOILER FROM
SERIES “PELLETHERM V.4 LT” AND AN AUTOMATED PELLET BURNER FROM
SERIES “GP XX SC”.
3.1. CONSTRUCTION DESCRIPTION OF STEEL MADE HOT WATER PELLET
BOILER FROM SERIES “PELLETHERM V.4 LT”.
The steel made hot water pellet boiler from series “Pelletherm V.4 LT” is designated for
heating of local installations, either built as systems with gravity water circulation or with
forced circulation through a pump. The heat exchanging unit is a module for automatic
pellets utilization and for heating of the circulations water. The cleaning of the ash residues
from the burning process is manual and can be performed through the front lower door of the
combustion chamber, by taking out the ash container and gathering its contain in proper
storage containers. The burning process organization and the heat exchange with the boiler
body surfaces ensure high efficiency of the appliance. The operation mode of the system: a
hot water pellet boiler from series “Pelletherm V.4 LT” and an automated pellet burner from
series “GP xx sc” depend on the chimney draught. The chimney draught depends on the
chimney condition, as well as on the flue gas temperature.
The hot water boiler’s heat exchanger construction from series “Pelletherm V.4 LT” complies
with the resistance requirements for such type of appliances: EN 303-5:2012 - "Heating
boilers. Part 5: Heating boilers for solid fuels, manually and automatically stoked, nominal
heat output of up to 500 kW. Terminology, requirements, testing and marking.
The hot water boiler consists of the following components/modules:
The main hot water boiler’s part is the boiler body (heat exchanger unit), as the
automated pellet burner from series “GP xx sc” is mounted on its side. The heat
exchanger is offered in 2 variants: the so called “left” and “right” mounting, i.e. the
automated pellet burner can be mounted either on the boiler’s body left side or on its
right side;
The heat exchanging unit is with steel made, welded construction. The combustion
chamber is formed in its front lower part, as the ash container is positioned under it.
The heat exchanger is with compact size relative to its heating output, because it has
3 pass construction providing high efficiency and optimal heat exchange;
The fire-clay bricks, mounted in the combustion chamber, provide optimal burning
process and help for complete fuel utilization;
The ash-tray is positioned at the bottom of the combustion chamber. The ash
residues are gathered there, as it provides simplified conditions for cleaning of the
appliance;
The water inlet and outlet muffs are positioned at the boiler’s rear side, with inner
thread G1½” and are used for connection to the heating system;
The flue outlet (with external diameter Φ 149 mm) is centrally positioned in the rear
upper side of the hot water boiler and is used for extraction of the flue gasses to a
chimney;
The steel made heat exchanging unit, its cover and doors are isolated with mineral
wool, which limits the loses of heat to the environment;
The outside decoration cover panels are made of steel plates and are painted with
quality color coating.
3.2. MAIN INFORMATION ABOUT THE AUTOMATED PELLET BURNER FROM
SERIES “GP XX SC”
The automated pellet burner from series “GP xx sc” has to be mounted horizontally on the
side (“left” or “right” mounting) of a hot water pellet boiler from series “Pelletherm V.4 LT” and
is a separate (standalone) module from the system.
