Metso And Fortum Heat Develop A Cutting-edge District Heating Network Optimization Solution

HELSINKI, Finland, Oct. 15, 2013 (GLOBE NEWSWIRE) --
Accurate control improves heat delivery efficiency by decreasing heat losses inthe network, and it also enables a plant to maintain optimal operationconditions during fast changes in electricity and heat consumption.Fortum's Suomenoja CHP plant in Espoo is the first power plant in Finland tooptimize the dynamics of its district heating network using multivariable modelpredictive control. This development work builds on the optimization workcarried out at the Fortum Suomenoja plant during 2012. Commissioning of the newcontrol is planned for 2014.The district heating network in the Espoo, Kauniainen and Kirkkonummi areas is alarge and complex network, consisting of the production of district heat andcooling, a delivery network, pumping stations and thousands of end users. Untilnow, optimal operating conditions in the district heating network have beenmaintained manually, and operators have had to run the network with more heatthan necessary."With the new automatic district heat delivery control system, it is possible toefficiently control the pressure and temperature of the district heating networkin different parts of the network. Accurate control improves heat deliveryefficiency by decreasing heat losses in the network, and it also enables us tomaintain optimal operation conditions during fast changes in electricity andheat consumption. Both improvements reduce fuel consumption and CO2 emissions,making CHP production an even more environmentally friendly form of heating,"says Timo Aaltonen, Production Director, Fortum Heat and Power Oy."The new advanced optimization solution will provide district heat producerswith both economic and environmental benefits through better network control.Metso has developed a performance solution that is based on customer needs andenables customers to better cope with their challenges now and in the future,"says Sami Pitkänen, Vice President, EMEA Services, Automation, Metso.According to Pitkänen, Metso's control solution will benefit energy companies inall countries where district heating is a widely used form of heating, such asFinland, the Baltic countries, Sweden, Germany and Poland.Located in Espoo, the Suomenoja power plant produces heat for the inhabitants ofEspoo, Kauniainen, and Kirkkonummi, and electricity for the national grid. Thepower plant produces approximately 1,800 gigawatt-hours of electricity and2,200 gigawatt-hours of district heat per year.Based on successful steam network optimizationThe new district heating network optimization solution is a continuation ofMetso's pioneering work on steam network optimization, which has proven to be asuccess around the world at CHP plants. Core to both solutions are Metso'soptimization experts who design, implement and configure the optimizationsolution based on each customer's requirements, steam network and systems.The solution is built on multivariable model predictive control, which iscapable of simultaneously controlling several network variables, predictingprimary variables and handling control constraints. At the Suomenoja plant, theoptimization package will be integrated into the existing Metso DNA automationsystem, but it can be integrated into any automation system used at a powerplant."Better control of temperature and pressure fluctuations at the heat plantminimizes heat stress to district heat piping, and thus is one tool to avoidsevere disturbances," points out Juha-Pekka Jalkanen, Director, PlantPerformance Solutions, Automation, Metso. "Better control of the pressuredifference throughout the network also removes the need to produce anyadditional heat, resulting in higher energy efficiency."Fortum's purpose is to create energy that improves life for present and futuregenerations. The company provides sustainable solutions that fulfill the needsfor low emissions, resource efficiency and energy security, and deliverexcellent value to its shareholders. The activities cover the generation,distribution and sales of electricity and heat as well as related expertservices.Fortum's operations focus on the Nordic countries, Russia, Poland and theBaltics. In the future, the integrating European and fast-growing Asian energymarkets provide additional growth opportunities. In 2012, Fortum's sales totaledEUR 6.2 billion and comparable operating profit was EUR 1.7 billion. It employsapproximately 10,400 people.The Automation segment's process automation and flow control solutions meet thegrowing needs of Metso's customer industries to improve production processefficiency as raw materials and energy sources become scarcer and their costsincrease. Our global network of service experts delivers business solutions toour customers that improve their productivity, lower risks and optimize, is a global supplier of technology and services to customers in theprocess industries, including mining, construction, pulp and paper, power, andoil and gas.
