Standard design pressure 2 bar

Our specially conceived screw feed assembly, the result of a single boiler-mechanical burner design.

Undergrate divided into sealed compartments for differen-tiated combustion air feed.

Very wide combustion chamber. Lined with refractory bricks and featuring a brick vault at the top to allow high combustion temperatures. Externally cooled with water between the walls to eliminate all heat losses to the outside.

Two-stage combustion, with grate-level gasification and a wide range of primary air/secondary air ratios above the grate according to the type of fuel used.

High quality, externally-insulated brick refractory cladding.

Tube nest and geometry of flue gas route guarantees minimum cleaning operations and complete accessibility. Large doors to access the grate level and removing the ash;

Temperature control system for automatically activating the discharge screw and fire safety system;

High combustion efficiency. With pellet fuel the efficiency may exceed 90%.

ACCESSORIES AVAILABLE ON REQUEST

Continuous heat output modulation: allows the heat input to be reduced continuously from 100% to 50% minimising the number of boiler shut-downs. A programmable logic controller connected to the water outlet temperature probe varies the rotation speeds respectively of the fuel feed screw and the combustion air fans using inverters that drive the corresponding motors.

Draught regulator: this keeps the draught in the combustion chamber constant, using a sensor device and a motor-driven throttle valve on the centrifugal dust separator assembly bypass duct or the flue gas exhaust inverter.

COMPATIBLE FUELS

• Waste from the processing of untreated wood and cork.
• Biomass (plant waste from agricultural and forestry activities and from the first processing phase of agricultural and food products).
• Wood pellets.
• Maximum amount of dry fuel ash: 2%.

MAXIMUM GRAIN SIZE ALLOWED, FUEL MOISTURE CONTENT, GUARANTEES ON THE COMBUSTION PROCESS AND EMISSIONS, will be defined contractually, based on specific requirements.
