  • Pumps for synthetic heat-transfer liquids

    As soon as the temperature in a heat-transfer system becomes too high for water, a plant operator must choose between petroleum-based or synthetic oils as the heat-transfer liquid. When modern petroleum oils are used, systems with feed temperatures up to about 300 °C can stay in service for their entire service life with one filling and with virtually no maintenance. Once feed temperatures ...

  • Heat Pump Used to Drain Contaminated Sludge in a Steel Factory

    Summary In 1987, new regulations required that factories dispose of their contaminated water and waste themselves. Making galvanised steel wire, the Stelfil factory produces sludge contaminated with lead and zinc. Stelfil spent thousands of dollars to bury this waste and evaluated three systems to remove most of the water: a gas dryer, an induction heated screw conveyor and a heat pump system. ...


  • Getting an air source heat pump from Better Planet – from first discussion to finished project

    Initial contact The initial contact is often on the phone and we try to establish if an air source heat pump makes sense from a financial and technical point of view. Heat pumps makes sense for most new built projects. For retrofits, heat pumps makes most sense for properties not connected to the gas grid. If you are connected to the gas grid, ...

  • Steam Heater Pulp Stock Heating Paper Mill

    After upgrading its bleach plant in 1987 to accommodate a two-stage elemental chlorine-free (ECF) bleach sequence, Cross Pointe Paper (now Flambeau River Papers LLC), Flambeau mill in Park Falls, Wis. subsequently added a totally chlorinefree (TCF) sequence in response to market demand. The TCF sequence, however, required heating, rather than cooling, of the mill's mediumconsistency stock during ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...

  • Efficient Dust Collection, Plus Product Recovery Benefit Fertilizer Manufacturer.

    Mears Fertilizer manufactures fertilizers and packages a recovered by-product, brine, for use as “ice melt.” Collecting dry fertilizer dusts from manufacturing and packaging operations is a major operations priority. Mears had used various types of dry “bag house” equipment, but results had been unsatisfactory. For a new installation, the company was determined to avoid bag houses. The area where ...
