Mobile plant for straw: 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 straw

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 straw shredder and conveyor, is installed outside the main container, along with a custom ash container and a chimney. All of which are connected to the mobile plant's main container.

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 straw

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 utilised to the maximum 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, resulting in higher efficiencies and better values on emissions.

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. 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 straw and other biofuels, and in utilizing the technology optimally in combustion plants with high operational reliability and usability.

. .

Control and surveillance

The plant is fully controlled by a PLC control system (Programmable Logic Controller). This system also monitors whether the plant is operating optimally. Both control and survillance is done via the internet.

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.

Aneby AMAQ

In 2014 Linka installed a large, mobile heating plant for the Swedish municipality Aneby. Wood chips and pellets are used for heating up the 250 attached houses.
