13.05.2015 ROLT group manufactured power units for RUSAL


ROLT group manufactured power units for RUSAL In the beginning of April 2015 ROLT power systems (as a part of ROLT group) manufactured and supplied power equipment for the factory "Ural foil" (Mikhailovsk, Sverdlovsk region) which is part of "RUSAL Inc". The customer of the project was "Mantrac Vostok" - the official dealer of Caterpillar in the Urals, which ensured supply of gensets for the plants. 

The block-module unit includes 7 power plants ROLT PSG 2000, boiler with heat exchanger of 18 MW and switchgear of 6 kV. ROLT power systems elaborated design documentation and produced 7 block-module power plants ROLT PSG 2000 in its factory in Kolomna. The power plants are equipped with gas reciprocating units Caterpillar G3516N with unit capacity of 2000 ekW and 1900 hkW, with 6.3 kV generator. The automatic control system of the genset ‘power manager RPM-01’ based on freely programmable controllers ComAp provides automatic acceptance\relief of load in stand-by mode, synchronization and division of active and reactive power between the units in parallel mode. 

Block-module container genset is a mobile building with separate functional compartments - engine room and electrical compartment. All power units are equipped with heat recovery system that ensures the transfer of useful heat from the cooling jacket and the exhaust gases into the consumer circuit. Heat recovery system with its main components: fire-tube boiler Aprovis and plate heat exchanger Alfa Laval, provides temperature range of 70 ° C/90° C. The new rooftop installation of cooling equipment provides greater reliability of cooling of the genset while working without heat extraction. For engine cooling is used the special scheme in which separate towers are used for the cooling circuit of charge air circuit and cooling jacket. 

"In each project we pay a lot of attention to the development of technological and installation solutions that allow our customers to get the most benefit from the gensets," - said Andrew Lomakin, technical director ROLT power systems. This approach can significantly reduce the cost of production for many manufacturers especially for metallurgical plants where the final cost of the product highly depends on the price of energy. For example, the price of electricity is about 35% in the cost of aluminum. 

After installation and commissioning the new power plant will provide electricity and heat for the equipment, administrative and industrial buildings of the factory "Ural foil". 

Sergey Goryachev, the director of packaging business "RUSAL Inc", said that due to gas reciprocating power plant "Ural foil" will not depend on external suppliers of electricity and heat and thus significantly reduce the cost of production.
