Springing into action when there are bottlenecks and being available around the clock in case of emergencies: if it were a job advertisement, the response would probably be limited. But LOOS boilers used in power stations frequently have to meet precisely these challenges. Basic heating is generally provided by special power-heat-coupled water-tube boilers. Shell boilers, which are easier to use, supplement the systems and act as auxiliary boilers for start-up processes to cover peak loads or ensure a basic load in emergencies.
The Vattenfall heating stations in Hamburg Barmbek and Eppendorf, for example, which are equipped with LOOS boiler systems, are intended for precisely this purpose. Their heat output of 47MW each is fed into the Vattenfall district heating network in Hamburg at peak load times. In addition the heating plants are also used to provide emergency back-up for the supply of heat to the Hamburg-Eppendorf University Clinic and the Asklepios Clinic in Barmbek, two of the most modern hospitals in Europe.
Vattenfall is among the leading power companies and is the fifth largest producer of electricity and the largest producer of heat in Europe. The heating plants were planned in detail and realised by Kraftanlagen Hamburg GmbH. The LOOS sales office north has already successfully carried out a range of projects in cooperation with this experienced plant engineering company. Two LOOS UT-HZ double-flue hot water boilers were installed in each heating plant.
All four boilers are fitted with integrated flue gas exchangers to maximise energy usage and reach a level of efficiency of almost 97%. The plants' emissions are well within the limits of European regulations and the local specifications laid down by the Hamburg environmental authorities.
One of the particular challenges in planning and constructing the Barmbek heating plant was the proposed location of the ultra-modern boiler system. The heating plant had to be integrated into the shell of a historic boiler house dating from 1914. The result is a total success, with the special charm of the listed building being completely conserved. So the Hanseatic city of Hamburg benefits both visually and in terms of the reliability of its heat supply.
LOOS International is a competent partner to energy supply companies throughout the world. For customers such as E.ON, EnBW, RWE and many other utilities companies, innovative LOOS shell boiler technology helps generate and provide the energy required.
