Eko Coal - CAST IRON SOLID FUEL BOILERS
PDF Download: Eko Coal Brochure
Characteristristics:
- Thermostatic draught control that governs insertion of air under the grille.
- Secondary air control
- Flue draught control
- Boiler temperature thermometer
Main characteristics:
- High combustion performance
- Excellent resistance to corrosive agents
- Combustion chamber of a regular shape to ensure maximum fuel load
Ease of loading and autonomous operating time: 
- Spacious fire box to increase autonomous operating time
- Spacious loading door
- Lever for loading door opening with an anti-burn soft rubber protection
Optimized combustion:
- Designed to ensure uniform thermal load
- Distribution of secondary air with pre-heating
- Bathed and finned grille
- Fire box with spacers between load and walls
- Rear element with rungs on a fire side and intermediate elements
Smoke path in three sections:
- Uniform air entry under combustion grille
- Less thermal stress
- Distribution of unburned residues
Three burning stages
- Stage1
The combustion by-products are carried by a special passage obtained in the rear element. In the same area, very hot secondary air is inserted which favours complete oxidation of the gases.
- Stage2
Gases from the rear element are sent to a wide-finned, self-cleaning zone, in the same time they make a favour entry into the third section.
- Stage3
The third section directs the smoke towards the
flue with adjustment shutter and door for cleaning.
