Looking back to the research question it is concluded that it is possible to make gypsum board from waste gypsum board is a more energy efficient process than the current process. For further research it is important to establish whether or not it is possible to produce gypsum board from 95 wt% waste gypsum board without deteriorating the material.

Gypsum Wallboard Production. Wallboards are made from either natural gypsum (calcium sulfate) or so-called byproduct gypsum calcium sulfate extracted in coal power plants. The raw material is mixed with water and additives. The mixture termed "slurry" spreads onto a moving sheet of paper and during the length of the production line it sets and

This hose reduces the flue gas temperature by 50 °C (90 °F). The out-coupled heat resulting from this process (two times 32 MW) contributes to heating the power plant feed water. Surplus steam from this process then adds to energy production which significantly improves the plant’s overall energy balance.

Oct 03 2012 · An energy audit is fundamental for plants that wish to control energy costs. The audit has two essential parts: 1) the analysis of purchased energy and how it's converted into other usable forms; and 2) an energy use and utilization analysis. The results can help identify areas that waste energy and how best to recover and reuse that energy.

Steam turbine systems generally have a power-to-heat ratio between 0.15 (40 kWh/GJ) and 0.23 (60 kWh/GJ). The power-to-heat ratio depends on the specific energy balance of the plant as well as on energy costs. A cogeneration plant is most often optimized to the steam load of the plant exporting excess electricity to the grid.
