Combined Heat & Power Plants 90 years with District Heating DESMI has been involved with supply of pump solutions for District Heating for approx. 90 years. As District Heating often has its source in Combined Heat & Power Plants (CHP – also known as cogeneration) DESMI has developed products and competences specifically for this type of applications. supply to the Zunhua CHP Plant in China. The power plant has an electrical capacity of 2 x 60 MW and supplies heat for 2.7 million m² of residential area. As seen on the illustration on this page using CHP for District Heating is an excellent...

Combined Heat & Power Plants The flexibility of heat sources for District Heating can be seen from the illustration below. There is an almost unlimited number of solutions, i.e. utilizing heat and power from Incineration/Waste-to-Energy Plants, Biomass Fueled Boiler Plants, Geothermal, Solar Heat etc. In Combined Heat & Power Plants there are both water and steam based pump applications. DESMI's solutions cover mainly the water based applications. Temperature levels in general below 150oC / 302oF and pressure levels up to a maximum of 25 Bar / 363 psi. DESMI has strong experiences with the...

Biomass Fueled Plants - Case Story Skanderborg-H0rning District Heating Co. supplies heat for a population of approx. 9.000. The heat system consists of 300 km / 186 mile distribution pipes, six heating plants and five pumping stations. The annual supply of energy is 275,000 MWh. The wood chips production covers 140,000 MWh/ year and replaces coal-fired heat from the Studstrup Power Plant. Wood chips heating is CO2-neutral and reduces the annual CO2-emissions by approx. 20,000 tonnes. The project consists of two boilers of each 10 MW. 50-60,000 tonnes of wood chips from local forests are...

Solar Heating Plants – Case Story Dronninglund Solar Heating Plant, Denmark DESMI e.g. supplied energy efficient NSL 125-265 centrifugal pumps for one of the world’s largest Solar Heating Plants, in Dronninglund in Denmark. The solar heated water is utilized for District Heating. Hot water storage dam: 60,000 m3. Solar Panel surface area of 37,000 m2. A Solar Heating Plant transfer the energy from the sun to clean energy. The solar energy is utilized instead of fossil fuels and thus helps reducing the CO2 emissions and the general pollution. Through this link you can see more about the...

Waste-to-Energy Plants (Incineration) Waste Management, Heat & Power Generation in One Solution Energy recovery from waste is a very good idea: 1 ton of waste can be converted to 2 MWh heat and 2/3 MWh electricity. In Denmark alone more than 3.5 million ton of waste is being incinerated every year. It is one of the popular ways to create heat and electricity and there is a strong trend to build a lot more Waste-to-Energy Plants around the world. Reason obviously being positive environmental as well as financial aspects. Vestforbrænding, Waste-to-Energy Plant, Copenhagen DESMI supplied many...

Waste-to-Energy Plants (Incineration) DESMI Pump Solution for the Transmission System at AffaldVarme Aarhus, Denmark High efficiency and big savings In May 2013 DESMI delivered an NSLH pump to AffaldVarme Aarhus. The pump was chosen on the basis of three parameters: • High efficiency and thus better operating economy due to the internal coating. Easy access for maintenance as the pump is mounted on the motor, which means that there are no other bearings than the ones in the motor. A fair and competitive price AffaldVarme Aarhus plays an important part in With power heat supply the consumers...
