The HERZ pelletfire 20/30/40 boiler is a module that combines a pyrolysis wood boiler and a wood pellet burning boiler. The transition to the use of pellets, after burning firewood, is automatic, which makes heating even more convenient.
Description of the structure
The PelletFire boiler consists of two units: a wood pyrolysis boiler and a pellet burning module. Fire-tube three-way heat exchanger with automatic flue gas cleaning and removal systems. Thanks to two autonomous combustion chambers at any time it is possible to switch the boiler to the required type of fuel: firewood or pellets. If there is a need for thermal energy after burning firewood, the boiler will automatically switch to pellet work. The revolutionary double vortex combustion chamber creates more optimal conditions for mixing pyrolysis gases with oxygen. The flame is divided into two chambers and thus efficient combustion is achieved. The chamber is made of heat-resistant concrete. In a pellet burner, combustion takes place on the so-called lowering grate, fuel is fed to the grate from above, primary air is supplied from below through the openings of the grate, 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 T-Control automation. The combustion process is controlled by a lambda probe. The ash is removed from the boiler automatically into 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 PelletFire boiler, HERZ Energietechnik recommends the use of a buffer tank.
The basic complete set of a copper includes the T-Control control panel which provides:
- weather-dependent control for 1 (one) mixing circuit
- Drive tank management
- DHW boiler heating control
- 60 ° C return line temperature maintenance
- automatic ignition
- Lambda control
- automatic cleaning of burner and heat exchanger, removal of ash into separate ashtrays
- Quickly diagnose errors (there is an error log)
