ORLIGNO - Model 500 - Pellet boiler
From Pellet Boiler
In its brand new assortment the Orlanski company has presented an appliance which, thanks to the technical solutions applied, ensures the comfort of use and reliability regardless of the quality of the fuel used. The Orligno 500 boiler’s construction was created based on 6 years of experiments and the research of various ideas regarding pellet combustion. The main target posed to the Orlanski company constructors was the creation of an appliance which would be user-friendly, clean while operating, and above all one that would provide the customer with a certainty that during the period of the highest demand for heat there would be no issues related to fuel combustion or supply. Moreover, the boiler’s construction enables easy access to themost important mechanical and electrical circuits.

Modernity, comfort, ecology
The compact Orligno 500 boiler with an integrated pellet tank is an appliance which is designed to combust ecological fuel- pellet with a diameter 6 – 8 mm and length 10 – 50 mm.
It is fitted with an automatic igniter and granule feeding system. The ignition process takes place by using a 400W ceramic heater.
The boiler is available with a nominal power of 25 kW, however, the range of work covers the power from 7 to 25 kW.
The uniquely constructed burner, made of heatproof steel, ensures the total combustion of supplied fuel while maintaining emissions which are safe for the natural environment. The feeding system which consists of two independently working feeders (upper and lower) enables not only the pellet supply but is also a safety device which prevents the possibility of the flame retracting back to the feeder due to the use of elastic, gravitational connection.
The fuel container whose capacity is 255 litresallows the boiler to operate for up to 170 hours.
Depending on the customer’s preferences the boiler may be adjusted to co-operate with an outer fuel container feeding systemt hrough the use of a suitable control system and a sensor package regulating the level of feeder fullness.
The boiler regulator, apart from basic functions essential to boiler operation, also controls the central heating pump, hot water for domestic use pump and heat accumulation tank’s feeding pump, and moreover controls its level of fullness.
The customer, when deciding on the brand new product from Orlanski company, receives a fully automated boiler whose efficiency is over 91% and his input is reduced to periodical controls and re-fuelling.

New solutions – ORLIGNO 500
The burner is the central element of every pellet combusting boiler. The most commonly used ones belong to the retort or chute type. Their ways of operating are different, they have certain advantages and disadvantages. Based on their experiments, the Orlanski company has fitted the Orligno 500 boiler with an openly constructed so called “shovel burner” which combines all the positive features of its market opponents.
Regarding the combustion process itself, Orlanski burner’s parameters correspond with the retort burner parameters. In both cases the supplied fuel is heated beforehand which positively influences the level of emissions.
In the Orlanski’s burner, issues related to fuel blockages on the burner and tracking do not occur due to the use of the feeding mechanism based on a roller and an open, lengthwise burner construction.
The Orligno 500 boiler’s burner, similarly to a chute burner, is verywell protected from the flame retraction due to the application of an elastic, vertical chute pipe as well as the feeder temperature sensor.

Controlling the pellet combusting process is not just about maintaining a certain operating temperature but also selecting an appropriate burner power depending on the current energetic need, monitoring the fuel combustion process and the appliance’s level of cleanliness and above all the provision of work safety via fuel cut-off in case of the increase of temperature.
Controller consists of the operator’s panel and the executivemodule which are connected with a special tape. Such solution enables easy access to the executive module and makes the boiler work unaffected by faults in the operator’s panel. The regulator has got a large displaywith an intuitive, descriptive menu.
The control system is based on an advanced work algorithm – Fuzzy Logic which ensures a fluent and intelligent adjustments of the supplied fuel and air as well as a 15% decrease in the amount of combusted fuel. The regulation enables two modes of setting the boiler working temperature: automatic and manual. With regard to the manual system, the temperature is set by the user whereas in the automatic mode the temperature is set automatically based on the need for energy. The range of control entails: central heating, hot water for domestic use, buffer and the mixing valve with actuator.
In the basic version the boiler is fitted with boiler, exhaust gases temperature sensor and the feeder temperature sensor.
The control over more advanced systems is conducted by the Orligno 500 boiler regulator cooperating with a Unicontrol type, modern, microprocessor system.
The Unicontrol driver controls the work of circulation pumps and the settings of three-way valves based on the outside temperature measurement, boiler temperature on feeding and the return of the heating element and the signal from room regulators.
