Mobile plant for wood pellets: 250 - 5,000 kW

Linka’s mobile plants are complete, turnkey heating plants placed in containers, customized to the plant’s size. The plant is delivered and installed by a crane on a prepared concrete foundation.

Mobile plant for wood chips

With a Linka mobile plant you are ensured a turnkey heating plant, built in a large standard or custom container. A fuel container with a walking floor is also installed, along with a custom ash container and a chimney, all connected to the mobile plant’s main container.

The wood chips are stored on the walking floor system, where a number of horizontal scrapers move the fuel to a sunken auger at the end of the system. It is transported to the main container by additional augers, through a cell lock to be transported into the boiler for combustion.

The main container is built in three sizes, depending on boiler size. It consists of a floor made of chequer plates, four sides in trapezoidal profiled sheets and a roof. The container is insulated with 100 mm insulation material and coated with galvanized perforated sheets. A single door is found in one end, and a double door in the other. The plant is assembled at Linka with all necessary equipment, plumbing and electrical wiring.

It is ready for commissioning when it arrives on site. The plant is usually in operation shortly upon arrival. .

Linka H-boiler – for wood chips

The H-boiler is a cylindrical, highly efficient channel flue boiler in a 3-pass or 5-pass version, designed for biomass combustion. The boiler features a smooth flame channel and water-cooled rotation chambers. It is dimensioned to achieve full combustion and efficient utilisation of the radiated heat in the flame channel, whilst convection heat is maximum utilised in the subsequent flue gas sections.

A moveable, water- and air cooled step grate is installed in the front of the boiler, to prevent clinker. Through our world patented combustion system, secondary air is added to the process in a downstream principal, to create the correct amount of turbulence in the combustion area. Hereby the developed gasses are completely burned,

Thorough insulation of the boiler with 100 mm mineral wool results in a minimal heat loss. The boiler is all-welded and gas tight, and delivered with flanges, connecting branches, counter flanges and safety outlets. A cleaning hatch at the backend of the combustion chamber makes inspection and cleaning easy. The standard version is designed for hot water with an operating pressure of 4 bar, and a maximum operating temperature of 110⁰ C.

The H-boiler can be designed for High Pressure Hot Water with a temperature of eg. 160º C, and adjusted for a pressure of eg. 10 bar. The H-boiler can be designed for High Pressure Hot Water with a temperature of eg. 160º C, and adjusted for a pressure of eg. 10 bar.

An elegant exterior of blue plastic coated steel plates gives the Linka H-boiler an appealing, modern design.

Automated usability

Linka has many years of experience in developing the special, advanced combustion technology for wood chips and other biofuels, and in utilizing the technology optimally in combustion plants with high operational reliability and usability.

You choose the collaboration

The plant is fully controlled by a PLC control system (Programmable Logic Controller). the plant or as a project collaborator, with us as the turnkey contractor for the entire system.

Automatic ash extraction

A stainless steel, laterally-mounted ash auger is fitted in the base of the boiler, to transport the ash out to the inclined auger. This auger moves the ash onwards to an ash container, e.g. outside the building.

Automatic flue pipe cleaning

A number of pressure tanks are mounted on the boiler along with soot valves. These inject air into the boiler’s flue pipes to keep them clean. This way, manual cleaning of the pipes is rarely necessary.
