Pellet boilers HERZ pelletstar ECO 10-60, with a capacity of 10 - 60 kW is an efficient and fully automatic heating boiler with low levels of harmful emissions. Pelletstar pelletstar ECO boilers are characterized by their small size, and therefore, especially small requirements for the installation site, economical operation and high efficiency. Automatic cleaning of the heat exchanger and combustion chamber ensures comfortable and convenient operation.
Description of the design
Structurally, the boiler body is a monoblock in the middle of which there is a burner with fuel supply and ash removal systems, and a three-pipe heat exchanger with ash removal and flue gas removal systems. In the burner, combustion takes place on the so-called lowering grille, fuel is fed to the grille from above, primary air is supplied from below through the openings of the grille, secondary air is supplied through the holes in the side walls of the burner. The ignition process is automated, takes place with the help of an electric heater with a blower, the temperature in the burner is controlled and regulated by Lambda automation. The ash is removed from the boiler automatically in separate ashtrays. The ash is removed from the burner by means of a lowering lowering grid and finds holes in the matrix by shaking the ash from the surface into the ash pan located under the burner. Ash removal from the heat exchanger also occurs automatically during boiler operation, which allows to maintain a stable boiler efficiency over the entire power modulation range from 30% to 100%. Operating cycles and operating times of cleaning systems can be changed. When designing a heating system with a Pelletstar boiler, HERZ Energietechnik recommends the use of a buffer tank (battery tank).
The basic complete set of a copper includes the Lambda control panel which provides:
- Combustion process control (use of lambda sensor)
- Return temperature increase (pump and mixing valve actuator)
- Heating circuit control, solar circuit control and hot water preparation are possible thanks to an external controller
