All components are perfectly attuned to one another in terms of design and performance perfectly - from planning to commission.

Hydraulic Fuel In-Feed

Material to be conveyed: Coarse fuels, edge length up to 600 mm (24”)

Transport Distance: up to 3 m (118’)

Transport Width: up to 2.4 m (7’ 10”), matching the width of the furnace

Output Range: up to 10 t/h

Technology: The fuel is being conveyed through a rectangular, horizontally placed shaft. A robust rectangular feed piston, driven by two parallel -connected hydraulic cylinders, is moving the fuel. The front edge of the piston is equipped with a cutting blade made from hardened steel, which is cutting off over sizes in the fuel. Included are dosing container with level control, level monitoring and extinguishing equipment and optional the hydraulic unit. The dosing container is placed directly on the feeder and built conically rectangular.

Multiple Screw Feeder

Material to be conveyed:  Fine and coarse fuels, edge length up to 300 mm (12”)

Transport Distance: up to 4 m (158’)

Transport Width: up to 2.4 m (7’ 10”), matching the width of the furnace

Output Range: up to 10 t/h

Technology: The fuel is being conveyed through a rectangular, horizontally placed shaft. Two to six screw spirals with a diameter of 280 mm (depending on the version) are arranged in parallel inside the shaft. This layout enables the continuous and very well controllable transport of both coarse and fine fuel particles, while simultaneously being unsusceptible to over-sizes. Included are dosing container with level control, level monitoring and extinguishing equipment. The dosing container is placed directly on the feeder and built conically rectangular.

Stoker Feeder

Material to be conveyed:  dust, shavings, wood chips, shells and pellets

Transport Distance: up to 3 m (49’)

Transport Width: up to 2.4 m (7’ 10”), matching the width of the furnace

Output Range: up to 4 t/h

Technology: Heavy drag chain conveyors (upper face), to transport coarse, uncut/uncrushed fuels. Including fuel feeding unit with hydraulically operated valves and level monitoring for the direct feed of grate firing systems.

Wood Log Feeder

Application: as feed-in system for grate furnaces utilizing primarily uncut/uncrushed materials

Material to be conveyed:  uncut/uncrushed material, edge length up to 1 m (3’ 3”)

Transport Distance: up to 15 m (49’)

Transport Width: up to 2.4 m (7’ 10”), matching the width of the furnace

Output Range: up to 4 t/h

Technology: Heavy drag chain conveyors (upper face), to transport coarse, uncut/uncrushed fuels. Including fuel feeding unit with hydraulically operated valves and level monitoring for the direct feed of grate firing systems.

Dosing Rotor Feeder / Flap Roll

Material to be conveyed:  Flow able fuels, edge length up to 50 mm (2”)

Transport Distance: Installation directly above the furnace

Transport Width: up to 2.4 m (7’ 10”), matching the width of the furnace

Output Range: up to 4 t/h

Technology: Designed as a rotary valve in full metal construction, the conveyor width corresponds to the width of the furnace. The drive is continuously adjustable by means of a geared motor with frequency converter, which allows an absolutely uniform and well-controlled fuel metering. Including dosing with level control, monitoring and extinguishing equipment. The dosing container is placed directly on the feeder and conically rectangular.

Injection System

Material to be conveyed:  Dry, dusty shavings and wood chips, edge length up to 50 mm (2”)

Transport Distance: up to 200 m (656’)

Output Range: up to 3 t/h

Technology: Direct transport of the fuel from the silo to the furnace by means of a transport-fan or indirect transport by rotary blowers, each including fan, pipes, locks, and the injection nozzle for installation in the furnace, in stainless steel or cast iron construction. The systems are well suited for retrofitting existing furnaces and boilers of all brands.
