Energy Efficient Pumps and Pump Solutions for District Energy PROVEN TECHNOLOGY

Energy Efficient Pumps and Pump solutions for District Energy District Energy: DE is the terminology used by the industry for the integration of District Heating and District Cooling. Heating and cooling systems in total account for 46% of global energy use. Therefore, these two systems (DH & DC) represent a huge potential for further reducing CO2 emissions. In response, we at DESMI are proud to be heavily involved in this business sector for which we design, manufacture, supply and support energy efficient pumps and solutions. Frontpage source: IDEA 2

District Heating & CHP's in Brief Dis District Heating is an energy distribution network that transports heated water generated in a centralised utility through piping to residential homes and commercial buildings primarily in urban areas. District Heating is clean, efficient and cost-effective due to its flexibility, scale of production and optimal heat generation conditions. The heat is often obtained from a CHP (Combined Heat & Power) plant burning fossil fuels or increasingly also biomass a.o. District Heating plants can provide higher efficiencies and better pollution control than...

District Heating District Heating History of Danish District Heating Denmark has unique experience with district heating, which is the reason why many foreign delegations visit Denmark, in order to learn from our competences as one of the most energy efficient countries world-wide. When the power stations in the large cities changed from diesel to steam heating in the 1930´s, many of them were combined heat and power plants, since the earlier development had obliged the stations to deliver heat as well. In 1903, the first waste incineration plant was inaugurated in Copenhagen. The same...

A number of initiatives were launched, including: • Systematic planning of heat supply for all areas • Biggest possible CHP generation on the basis of such planning • Improved insulation of buildings • Development of highly effective district heating pipe systems, pre-insulated pipes with high insulation properties and low installation costs • Reduction of operating temperatures in district heating systems and a variable flow in the pipelines to secure the most economical operation in the overall production and distribution system. The world's largest Today, the Copenhagen district heating...

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 miles 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...

Waste-to-Energy Plants (Incineration) Waste Management, Heat & Power Generation in One Solution 1 ton waste 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...
