ORLAN/ORLAN SUPER

Wood gasification



Wood is a widely available fuel and also one of the least expensive resources. In the correct wood combustion process small amounts of harmful substances are produced, such as NOx, CO, Hydrocarbons, breathable dust and the amount of ash produced is about 1% of the mass of the fuel load (this depends on the dust content of the wood).

Orlański's wood gasification boilers are adapted to wood of various particlesize distribution: wood logs, logs and chips. Sawdust and chips should be burned along with wood logs. Technical parameters resulting from wood combustion processes meet the most rigorous European norms and provide nearly twice as much heat as traditional boilers or fireplaces. The appliances can work in open as well as pressurized systems in accordance with current regulations.

 Use

ORLAN SUPER (18-80kW) boilers are designed for heating various types of buildings. They are commonly used in detached houses, drying facilities, industrial units and workshops.

ORLAN SUPER 96 or 130kW boilers allow the heating of larger areas such as large industrial buildings or public facilities.

Advantages

 
  • Up to 91% effi cient
  • Range from 18 to 130kW
  • Large loading capacity
  • Length of wood logs:
    - 50cm (18kW, 25kW, 40kW)
    - 75cm (60kW)
    - 100cm (80kW, 95kW, 130 kW)
  • Small amount of ash residue
  • Low maintenance costs
  • User-friendly construction
  • Up to 12 hours continuous operation
  • Modulated fan power 30-100%
  • Adjusted to work in pressurized systems thanks to cooling coil installed in upper part of boiler body
 
  • Electronic controller with possibility to connect remote EKOSTER CONTROL
  • Made from the highest quality 6mm steel
  • Environmentally-friendly – almost zero CO
  • Half-round fi regrate
  • Two inner boiler flues of 180 mm
  • Two cleaning mechanisms from left and right side of the boiler
  • Extra lever on the right side for ease of opening of boiler flaps

 

How do I know which boiler is suitable for me?

 

   
  • An installation designer will estimate how much heat heat will be required in the building.

  •  The result needs to be increased by 20% (so called boiler over-sizing).

  • See the graph opposite for to give an indication of the correct boiler that may be suitable.

Controller

 

The EKOSTER 2 microprocessor temperature controller is designed to control the heating process and the activation of the circulation pump in the central heating installation.
 

 

 

EKOSTER controller used in the
ORLAN boiler

 

Controller features

 

The regulator fulfi ls the following tasks:

  • Maintains the preset boiler temperature through the heating control
  • Automatic control turn-off after boiler extinction 
  • Blocking fan operation when stoking to the boiler 
  • Central heating circulation pump control “COMFORT SYSTEM”– a system that prevents pump blockages when the boiler is not in operation overheating
  • Protection from boiler freezing and overheating 
  • Signalling when the boiler temperature sensor is damaged
  • Compatible with EKOSTER control remote control system
