waste heat recovery Articles

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

  • A study on the thermodynamic analysis of a cascaded latent heat storage system over the single storage tank system for diesel engine waste heat recovery

    This article presents the comparison of performance of a cascaded Latent Heat Storage (LHS) system over the Single Storage Tank (SST) system for heat recovery from a diesel engine. The energy and exergy saved and efficiencies during the charging process are evaluated and reported using actual system data. The discharge process is analysed with a case study and it is concluded that it is possible ...

  • A novel cogeneration cycle based on a recompression supercritical carbon dioxide cycle for waste heat recovery in nuclear power plants

    In this study, a novel cogeneration cycle based on the recompression S–CO2 Brayton cycle is proposed, analysed and optimised thermodynamically to utilise the waste heat from a nuclear power plant. The cycle was constructed theoretically on the basis of a transcritical CO2 power cycle and a LiBr/H ...

  • Energy conservation in aluminium foundries by waste heat recovery from solidifying molten metal

    This paper presents a unique attempt to preheat the raw materials by recovering the waste heat from solidifying molten metal in shape castings of aluminium using sand moulds. Finite element analysis of the problem using ANSYS has also been done, results of which show satisfactory agreement with the experimental results. By using this preheating method, it is proved that around 16% of heat ...

  • WEISS provides for the heat - and disposes of the waste case study

    The very first time PLIMOB learnt about Weiss was in 1995 at which time contacts at IKEA told about combustion plants from WEISS. IKEA is the most important customer for PLIMOB so the management listened to the recommendations. PLIMOB is producing wood furniture; large quantities of wood chips and sawdust are a spin-off effect from their production. Traditionally wood-working industries – ...
