Message from the board

Steam is an essential element in the energy supply system. As a primary energy source, it fulfills many important functions, whether it’s used to operate a turbine, as process steam for use in industry, or for district heating. Therefore, heat recovery steam generators (HRSG) are important components of many power plants: They substantially increase a plant’s overall efficiency, and help to minimize the costs of fuel.

You also benefit from greater flexibility when operating at part load during load changes or by simply utilizing one of our diverter bypass stack systems. Also in other areas of the energy system HEAT is key.

Did you know that heat demand accounts for over half of the total energy use globally? This means that heat transfer is key in the energy transition moving forward, and we at NEM are committed to support that transition with new energy solutions in the area of heat transfer.
