General information on hot water boilers

3.1.
"TECNIKA" hot water wood gasification boilers are have a steel structure and use solid biomass, in the form
of wood logs, as fuel. The boiler is designed for connection to hot water heating systems.
Tecnika boilers comply with P.E.D. 97/23/EC.
TECNIKA series hot water wood gasification boilers consist of the following components:
 "TECNIKA" hot water boiler - 1 (one)
 ceramic ducting element in combustion chamber - 1 (one)
 thermal valve for controlling air flow rate - 1 (one)

steel brush for cleaning ashes - 1 (one)
 ash scraper – 1 (one)
 "TECNIKA" series hot water boiler use and instruction manual - 1 (one).

3.2.
The "TECNIKA" hot water boiler heat exchanger complies with the operating requirements of this type of
appliance, as set out in the operation standard:
The hot water boiler consists of the following components/modules:
 heat exchanger, consisting of a welded steel plate structure. The upper part of the boiler
accommodates the fuel hopper which is manually filled with wood logs. The fuel chamber is the ideal
environment for the fuel pyrolysis process and volatile gases are conveyed towards the lower section
of the boiler, where they are oxidised in the combustion chamber. The combustion chamber contains
a ceramic coating, a nozzle and a combustion gas ducting element to ensure combustion process
efficiency;
 combustion nozzle, made of ceramic material, positioned in the lower section of the fuel hopper
to ensure optimal conditions for combustion process efficiency;
 ceramic ducting element, positioned in the boiler combustion chamber allows high temperature
levels and guarantees optimal fuel oxidation;

combustion gas fan fitted on the back of the boiler conveys combustion gases outside the boiler
and controls its operation;
 air distribution box, provided with primary air control valve. This box doubles as heat exchanger
and pre-heats the ambient air before it is used in the combustion chamber of the boiler. The inlet of
this box is provided with an inlet control fin actuated by a thermostat valve and controls the air
taking into the boiler;
