The KA-8000 boilerThe KA-8000 boiler

          The KA-8000 boiler has been designed to provide two main functions:producing asphalt inside the boiler and collecting ready asphalt from the bituminous mix plant, including its transport to the working site. The KA-8000 boiler for producing and transporting gussasphalt and hard gussasphalt can be provided in an encased version, on a towed trailer or a vehicle frame, with appropriate load capacity.
          The drive unit of the KA-8000 boiler is a high quality, high pressure, two-cylinder Hatz combustion engine (75 dB) of the silent pack type. The engine drives a high capacity hydraulic pump, which, in turn, propels a hydraulic engine. The hydraulic engine drives a mixer (variable adjustment), with a range of 0 to 9 rpm, using a set of RBS distributors. The mixer has a bearing support and is mounted vertically inside the tank. The pump also drives a hydraulic cylinder, which opens the bolt of the discharge system. 
          In addition, the combustion engine propels an AC generator, which feeds an oil burner, and controls and provides lighting for the working area. Additionally, it also provides lighting for the platform of the engine room, as required. 
          The high capacity tank is made entirely of certified boiler plate. It is insulated with a layer of insulating material, 100mm thick. The tank's outer shell of the KA-8000 boiler has been made of acid-proof sheet metal plate so as to provide anticorrosion protection.In the upper part of the tank there is an enlarged discharge opening, which enables the acquisition of asphalt both from new and old types of bituminous mix plants.
          The heating and maintaining of temperature for various types of asphalt is done through using a powerful oil burner, which is integrated with the electronic system that controls the asphalt temperature. The purpose of the control system is to maintain the set temperature and prevent the overheating of asphalt. This is done through a set of reliable, high quality temperature sensors, as well as controllers and indicators of control line I. 
          Additionally, the control system has a temperature sensor of control line II. Its purpose is to shut down the entire heating system in the event of failure of the control elements of line I. The precise proportioning of asphalt is carried out by a hydraulically-controlled bolt of the discharge system and an appropriately profiled trough.
