The challenge:

The customer has a Linka boiler to heat the factory by burning wood chips from production. The customer’s chip silo is too small and its cone-shaped bottom is unsuitable for sawdust/shavings because the material bridges inside and cannot be fed out. In the summer, surplus chips are transported away in containers. In winter, it struggles to produce enough wood chips to heat the factory.

The solution:

It is decided to connect the boiler to the city’s district heating system so that heat can be exchanged both ways. Weiss ApS. Installing a new and larger silo, with a flat bottom and a Weiss NFU 600 outfeeder. In addition, a solution is designed for filling wood pellets during periods when not enough wood chips are produced for firing. Throughout the conversion phase, the customer borrows a mobile 3 MW oil boiler from Weiss. This is connected to the heating system until the district heating is connected.

Now:

The facility after reconstruction: The existing chain conveyor is now used, along with a new unloading station, to fill with wood pellets in the winter. The chip silo has double the capacity compared to before. With the new Weiss outfeeder, there are no longer any problems getting the material out of the silo and into the boiler. In the summer, surplus heat is fed into the local district heating network.

After 5 months at Middelfart Fjernvarme, the loss of Weiss became too much for Ronni Andreasen.

We are therefore pleased to announce that Ronni, a highly valued employee, has returned to Weiss ApS.

Both the employees and management at Weiss are thrilled to have Ronni back.

Welcome back, Ronni!

We have been working for the NHS at Raigmore Hospital in Inverness for the past few years, where we have installed two 1.6 MW biomass pellet boilers that produce steam for the hospital’s laundry/cleaning facilities.

Our Service Engineer is currently there to provide support and training to their operating staff.

We are currently working on the production of a pusher piston for a Weiss wood chip pusher, which will be delivered and installed at Ølgod Varmeforsyning.

We are in the process of replacing the feed system on a wood chip fired non Weiss boiler for a customer on Bornholm.

Tasks consist of delivering, installing and commissioning a complete new Weiss system, consisting of:

• New double receiving hopper.
• New dosing tank with fire damper.
• New hydraulic pusher.
• New water-cooled duct.

Start-up of the system is scheduled for early November 2022.

Weiss is now finishing updating an older steam boiler with original retort principle at a customer on Funen.

It has been a major upgrade project where we have installed:

• A new complete Weiss stoker w/cell sluice.
• A new Weiss 1000 KW push grate for wood pellets w/hydraulic station.
• A transition section from grate to boiler.
• A new option for better air control, new primary/secondary fans.
• New ash augers.

The parts have been produced in Linkas Produktion in Lem, based on Weiss technology and know-how.

There was a First Fire on Wednesday, September 29th and now a little trimming and test drive is needed. It is really well done by all involved.

The 2 specially designed ECO tops with built-in gunshot cleaner are ready for shipment to Norway.

The customer wanted a more innovative solution that minimizes the risk of leaks and makes ongoing maintenance easier and more time-saving.

We at Weiss look forward to the customer getting this solution installed and tested and look forward to further deliveries of this innovative design/solution.

Our Field Team is finishing the Plant upgrade, servicing and repair of the Waste Incinerator in Greenland, so it is now in tip-top condition and ready for the Arctic winter.

The final details are finalized and the team continues back to the Netherlands for a major service assignment over the summer holidays on 2 x 11 MW biomass energy plants.

One of the appreciations we get from customers is the great flexibility in services over a summer vacation when most others are on vacation.

We have just started a major audit for a great customer in the Netherlands:

• Replacement of stainless steel Quench pipes.
• Repair of bag filter.
• Replacement of damper in ECO.
• Repair of the grate

We expect to be finished by the end of November.

Weiss OEM suppliers are selected according to various criteria. Among other things, they must be certified to ISO 9001 and ISO 14001. Using certified suppliers ensures that production is in order, that raw materials (radioactive, otherwise contaminated, different contents) and production are controlled.

The casting is tested with a spectrometer twice before it is released. What is the distance from the casting to the model? Is cooling under control? Post-processing, etc.

In addition to the chemical composition, mechanical durability is extremely important. DIN-compliant materials are used, so the tensile strength and working temperature range are strictly defined.
