Kris Project - Trailers e mobility

Mobility is the main feature of the Kris system, designed and sized with the highest degree of axing and in such a way that it is installed directly on semi-trailers, suitable for free transport by road. The engineering of the Kris project also provides for it to be installed without ancillary infrastructure.

The 8 semi-trailers plus 1 skid -demountable boiler are set up with the following systems:

• Rotary oven;
• Vertical post-combustion chamber (Ia section);
• Horizontal post-combustion chamber (IIa section);
• Air/flue gas heat exchanger (Ia sezione);
• Dry flue gas treatment plant;
• Wet flue gas treatment plant;
• Control Room and Distributed Control Systems (DCS) and Pollutant Monitoring;
• Generator group and general plant services;
• Thermal cycle skid
• Detachable steam generator

It is not necessary to build sheds to accommodate the plant that is able to operate outdoors.

The "mobility" criterion includes:

 

• The transportability of the system on the various types of roads;

 

• The adaptability of the plant to different types, conformations and characteristics of the soil;

 

• The maximisation of engineering, in order to have materials related to the transfer of the plant from one site to another and the commissioning on the new site;

 

• The wide operating range, in fact the plant, was designed to be able to work without infrastructure such as sheds and can operate under climatic conditions that our engineers have determined to be from -10 degrees C to 40 degrees Celsius of external temperature;

 

• Minimizes disassembly and reassembly times;

In the sizing of the various equipment and components and in the definition of their assembly, all design and functional solutions aimed at minimizing economic charges and time required for the installation, uninstallation and transfer phases have been adopted.

Special care has also been placed in the selection of refractory and insulation materials, which are suitable to withstand the problems related to thermal shocks resulting from the discontinuous operation of the plant.

In addition, in order to facilitate the transfer of the unit, the refractory material is of significantly reduced thickness and covered with steel plates, arranged in scales, to limit the weight of the equipment and to prevent damage to the refractory.

The mobile system is structurally arranged on nine rubberized, normalized and shaped vehicles, which allow a rapid movement on the road without the need for escort and speed limitation.

The plant's floor layout and the design of the various assembly components (connections, pipes, cables, ducts and connections) are such as to minimize disassembly and reassembly operations during the transfer of the plant.
