HEAT AND ELECTRICITY CONSUMPTION OF LARGE INDUSTRIAL ENERGY USERS IN THE NETHERLANDS

On the basis of information that can be extracted from existing databases, combined with information from literature and interviews, a database called BIN has been constructed containing data about the consumption of fuel, steam and electricity by approximately the 300 largest energy-consuming industrial plants in The Netherlands. Comparison with national statistics shows that the industrial plants incorporated in the database are responsible for 80% of the total industrial demand on primary energy carriers (excluding their use as feedstock). Thirteen industrial plants already cover 50% of this demand. The paper and board industry, the refineries, the chemical industry, and the basic metal industry are almost completely covered by the BIN database. From the database the distribution of the electricity and steam consumption over size classes has been derived. This article also gives the temperature distribution of the industrial steam consumption in The Netherlands. Of the 64 million tonnes of steam produced in boilers in the industrial plants included in the database the weighted average enthalpy is 3.17 MJ/kg and the average exergy is 1.29 MJ/kg, both with liquid water of 10-degrees-C as the reference. The plant-specific data included in the database can be used for research into industrial energy conservation measures, e.g. the combined generation of heat and power (CHP).
