FACI FSS 1000 wood chip boiler

The FACI FSS wood chip boiler with a unique three-cylinder high-efficiency heat exchanger is designed to heat infrastructure facilities using wood chips as fuel at natural moisture content.

Understanding the importance of uninterrupted operation in any situation, Italian engineers developed a backup fuel operating algorithm — already in the basic configuration the boiler runs on pellets automatically, and on coal, firewood and briquettes manually. Optionally the boiler can be fitted with additional equipment to run on coal automatically.

FACI's Italian engineering team developed specially for wood chip boilers a unique burner with 2 combustion zones (the main zone and a burn-out zone).

This method of burning wood chips at natural moisture, where unburnt fuel from the main burner zone falls under its own weight into the second zone and burns out completely there, is considered perhaps the most efficient way to burn wood chip fuel

The path of air supply and movement in the combustion zone has no equivalent on the market and is the pride of the FACI plant.

FACI two-zone wood chip burners with a unique air supply system have proven themselves excellently among European users and are rightly considered the most popular wood chip burners on the European and Russian market for wood chip boilers.

Horizontal heat exchangers are the signature feature of FACI boilers. The boilers are designed so that the flue gases from the burnt fuel pass repeatedly AROUND the cylindrical heat exchangers.

This makes it possible to achieve maximum heat recovery from the flue gases and an efficiency of more than 90%.

The FACI FSS fuel feed is one of the safest in the world. Safety is achieved by installing 2 reinforced augers with independent high-power geared motors, which separate the burner feed zone from the boiler's day hopper.

Anti-smoke system additionally directs air into the combustion zone through the lower auger, preventing smoke from entering the boiler room through the day hopper.

These solutions have achieved maximum operational safety , which is especially important at sites with full automation and no permanent staff.

Taking into account the specifics of the fuel (wood chips), FACI's Russian-Italian engineering team developed a unique fuel agitation system in the boiler's day hopper, which prevents wood chips from bridging in the hopper and stopping combustion.

Already in the basic configuration there is an option to install an additional 8.5 m³ vibrating hopper, which makes the boilers suitable both for small businesses — sites with a small area — and as part of existing or new block-modular boiler houses used by heat supply companies and large enterprises to heat infrastructure facilities
