The stamping ceremony for the WtE boiler after the boiler pressure test. The photo shows the flue gas cleaning system of the WtE boiler plant together with the boiler and the bunker located behind it.

Construction works on the slag valorisation building. The picture shows the quarters for collecting material after the Thermal Waste Conversion process.

Earthworks in the area of the derivation of the electrical power generated at the WTE plant to the 110kV transmission network.

Elements of heat production for the Municipal Heat Network, i.e. the heat exchanger during installation in the machine room building.

WtE – view of the secondary air system for the boiler. The purpose of the secondary air is to create a vortex flow of flue gases inside the first pass of the boiler.

WtE. What we see is the installation process of the crane beams in the waste bunker space (fuel for the WtE boiler). There will also be rails installed, on which the cranes that supply the WtE boiler with fuel will move.

Construction of WtE. The photo shows the façade of the staircase with the lift used for service and communication between different levels of PLB, on the left, the concrete and steel structure of the engine room building in which, among other things, the turbine unit will be installed, on the right, the flue gas cleaning installation inside the building.

Construction of WtE. The control room and administration building, the main concrete work has been completed and the façade work is now underway with the installation of the insulation before the final façade layer.

Construction of WtE. View of the engine room roof structure where the turbine unit will be installed. On the left, behind the steel structure of the building, the boiler is installed.

Construction of WtE. Installation of the insulation wool on the flue gas duct in the flue gas treatment part of the plant, the next step will be the installation of the sheets as seen behind the scaffolding. The proper execution of the thermal insulation is very important, not only for safety reasons, but also for the process itself. Flue gases with a temperature of over 140 oC will flow in these ducts.

Construction of WtE. The picture shows the two pressure vessels of the steam and water system of the plant, the so-called thermal deaerators. Their function is to remove the gases contained in the liquid.

Construction of WtE. The first large technological components in the machine room building. The picture shows two heat exchangers whose main task is to recover heat from the steam that has already driven the steam turbine. The heat recovered in these exchangers will be transferred to the Municipal Heat Network.

Part of the fire precaution system, i.e. a tank with a supply of water to extinguish a possible fire, and behind it a fire pumping station, where two pumps are installed to pump water to a system of hydrants and other fire protection equipment that use water. The water supply in the tank is automatically replenished from the municipal water supply network.

In the background, tanks with a stock of light fuel oil for the two boilers of the Peak Load Boiler Plant and for the start-up burners of the WTE boiler. In addition to natural gas, light fuel oil is one of the two fuels that will be used to produce heat from the PLB. In the foreground you can see where the firefighting foam generation system is connected to protect these tanks.

Two elements of the Waste to Energy Plant. On the left, the structure of the boiler house (grey steel beams) with the boiler visible inside (brown elements) before the installation of the thermal insulation and the green support structure of the boiler itself. On the right, you can see the communication pylon , its purpose is to connect all levels of the WTE boilers house with the Engine Room, where the turbine unit will be installed, and the Control Room (the room from which the entire Plant is controlled). Inside the pylon, in addition to a staircase, there will also be a passenger and freight lift available for service.

View from the upper floors of the administration building. The picture shows the Peak Boiler House with two water boilers used to produce heat for the residents of Olsztyn. On the right you can see a large power generator (a grey container with luminous elements on the roof) which is the emergency power supply for the whole Plant. Thanks to this device, even in the event of a complete lack of electricity from the power grid the Installation can be started up and go into normal operation. In the background – the panorama of the southern part of Olsztyn.

The photo shows the structure of the bunker building made using the slip-forming method, as well as the switchyard building used for administration, plant management and electrical switchgear.

In the foreground, the structure of the boiler house building with the flue gas cleaning system inside. The components visible inside the hall are only a part of the entire flue gas cleaning system (less than half of this equipment is visible in the picture). The installation meets the highest emission standards.
