EAC Declaration of ConformityThe air flow in the FACI solid fuel boiler follows a unique technology that achieves optimal air supply to the boiler without automation.
The air mixture enters the boiler through an adjustable damper on the right or left side.
The air mixture then passes through the air duct and perforated baffles, along the rear wall of the boiler and out through openings in the ash box.
A huge loading chamber is an important advantage of FACI TT boilers.
Look at the boiler dimensions and compare them with boilers of similar output offered to you — and it will immediately become clear where truly long burning is.
The air then passes through the grate and sustains combustion of the fuel at the very centre of the boiler — under the heat exchanger.
This achieves efficient and truly long burning.
In the FACI TT we use removable grates. We do not make the grates part of the heat exchanger (water-filled), because if they burn out, what would you do — replace the boiler? We offer to replace only the grates.
Traditional for FACI boilers drum-type fire-tube heat exchanger.
Horizontal heat exchangers are the signature feature of FACI boilers. The boilers are designed so that the flue gases from the burnt fuel repeatedly pass AROUND the cylindrical heat exchanger.
This makes it possible to achieve maximum heat recovery from the flue gases and high efficiency.
And by installing turbulators you can increase efficiency by a further 5-7%!
