  • The Major Components of Heat Exchangers

    Heat exchangers are not only one of the most common pieces of equipment found on industrial sites, they are also one of the most important. Despite the name, heat exchangers are used for both heating and cooling and are actually used more often for cooling, especially on industrial sites such as refineries or processing plants. These pieces of equipment are not “one size fits all.” In ...

  • The Aberdeen Heat and Power district energy schemes - Case Study

    District energy schemes seemed to be the right decision for the Aberdeen City Council (ACC). They had conducted a study of its housing stock and established that the multi-storey buildings (of which they have 59 in Aberdeen) were too expensive to heat. These buildings also had lower energy ratings, thus people living in them were subject to high energy bills. In 2002, as one of the results of the ...

  • RELAP5-3D modelling of heat transfer components (intermediate heat exchanger and helical-coil steam generator) for NGNP application

    The Next Generation Nuclear Plant project is aimed at the research and development of a helium-cooled high-temperature gas reactor that could generate both electricity and process heat for the production of hydrogen. The heat from the high-temperature primary loop must be transferred via an intermediate heat exchanger to a secondary loop. Using RELAP5-3D, a model was developed for two of the heat ...

  • Energy and exergy analysis of a 16–MW combined cycle district heating system with performance improvements

    Results of an energy and exergy analyses performed on a 16–MW University district heating plant located in the Northeast USA are presented in this paper. Unlike past studies, this paper uses actual data to assess CHP plant performance for all the 8760 h in a year (2011). A system of such complexity, considering the large volume of data available and large variations in system load, has not been ...

  • Customers problem: steam injection tank heating

    Northwood pulp and Timber Company in Prince George British Columbia, was plagued with a problem of violent vibrations and banging when heating a large volume paper machine chest with a conventional steam sparger. The tank walls were lined with ceramic tiles which were cracking, sections were coming off the wall due to the vibration from the collapsing steam bubbles. Komax Solution: Bill Neville, ...

  • Invisible Structures’ Products vs. Heat Island Impacts

    As many city residents can tell you, cities can be very hot places during the, summer. On warm summer days, the air in a city can be 6-8°F hotter than its, surrounding areas. Scientists call these cities "Urban Heat Islands." What, causes this to happen? There are fewer trees, shrubs, and other plants to shade buildings, intercept, solar radiation, and cool the air by "evapotranspiration." ...

  • Case study - Heat exchanger retrofit

    Overview A manufacturer of insulation films for the electronics industry needed to evaluate the capabilities of four existing oxidizers that treated emissions from its coating lines. The company was concerned that, due to oxidizer deficiencies, it would not meet regulatory requirements. The oxidizers had been manufactured by two different companies. One of them was no longer in business; ...
