Polish power plant chooses environmentally-friendly energy
Bosch Industriekessel supplied 6 shell boilers
Polish power plant Elektrociepłownia Zielona Góra SA is replacing its coal-fired boiler with a view to minimising emissions so that it can make a significant contribution to climate protection. The coal-fired power plant had already been replaced with a gas and steam power plant in 2004. Five hot water boilers and one steam boiler from Bosch Industriekessel have been in operation on the site since June 2012. Natural gas or light fuel oil is being used as fuel.
Elektrociepłownia Zielona Góra supplies heat and power to the city of Zielona Gora with its 120,000 inhabitants. The Polish power plant is part of the EDF Group, which has its headquarters in France and is the second largest producer of electricity in the world. The order for the shell boilers was placed via Loos Centrum in Poland, a sales partner of Bosch Industriekessel for many years. As the direct point of contact locally, Loos Centrum was able to support the Polish construction company Mostostal Warszawa S.A. in all aspects of industrial boiler technology.
The hot water boiler system has a total capacity of 160 megawatts. It supports the district heating generation at peak load times and provides emergency back-up should the power plant come to a standstill. The Unimat UT-HZ hot water boilers are equipped with speed-controlled and oxygen-regulated firings and also feature integrated flue gas heat exchangers. A water service module WSM-V with a deaeration capacity of 30 tons per hour is able to provided treated feed water in case of need or in the event of an emergency.
A steam boiler UL-SX with a capacity of 9,000 kg per hour acts as an auxiliary boiler providing the necessary steam for the starting process of the power plant. The boiler is equipped with a superheater module; instead of saturated steam, superheated steam is generated. An integrated economizer, a low-emission burner and an additional WSM-V water service module complete the system. The operation of the steam and hot water boilers is controlled by the innovative BCO/SCO controller technology.
In deciding to invest in new boiler technology from Bosch Industriekessel and move completely away from coal as a fuel, the Elektrociepłownia Zielona Góra power plant is minimising CO2 and NOx emissions, thereby demonstrating high levels of ecological responsibility.
On route for Zielona Góra: loading a hot water boiler at the inland waterway port of Roth in Central Franconia. The shipping weight of a boiler like this is almost 93,000 kilos.
