Energy efficiency thanks to waste heat recovery Innovative concepts for the glass industry Heat Recovery Answers for industry. Don’t let your money disappear into thin air Economically efficient generation of energy from your own source of waste heat Flue gas as source of waste heat Strong partnerships for intelligent solutions The enormous energy that is needed in glass manufacturing is normally supplied by fossil fuels. In this industry, large amounts of waste heat with temperatures between 400°C and 800°C are produced. However, many companies are still failing to make use of such heat for energy-generating purposes. Siemens supports its worldwide partners in the planning and erection of innovative heat recovery systems while helping to keep down investment costs and the additional expenses incurred for the operation of such systems. 2 Innovative waste heat recovery against rising energy costs and for environmental protection In the waste heat boiler, the waste heat of flue gas can turn water into steam that drives a turbine to produce electricity by means of a generator. The steam is then turned back into water in a watercooled or air-cooled condenser, after which it is taken back to the waste heat boiler, where circulation can begin again. This system can also be used for water heating and refrigeration or for heating buildings. Another possibility is to use the steam for downstream stages of production. Your benefits: • You can use the electrical energy thus produced to meet up to half your total electricity needs • Heating in winter and cooling in summer • High savings in respect of electricity costs • The power equipment can be installed without interruption of the ongoing production process • Secure supply of your own electricity • Can be integrated in the existing instrumentation and control system without having any effect on the process. Heat recovery in the glass industry Plant efficiency Waste heat Heat recovery Energy for the production process Glass Raw materials Integration in the process control system Seven good reasons for heat recovery equipment Control of the heat recovery equipment can be integrated in the SIMATIC PCS 7 process control system for glass production. Control and monitoring are therefore carried out from the central control room, and uniformity of automation is thus ensured throughout the entire plant. 1. You reduce your energy consumption costs by producing your own energy 2. Less dependency on external sources of energy for which prices are constantly rising 3. Economically efficient energy production through the use of innovative technology that requires little maintenance 4. Professional planning and fast installation 5. Low capital investment due to the use of inexpensive standard components 6. Fast amortization within just a few years 7. Reliability of the equipment thanks to the use of tried-and-tested components Your benefits: • Your existing control team is trained during commissioning • No additional personnel required in the control room • User-friendly operator control and monitoring • Use of standard components • The power equipment’s instrumentation and control system can be integrated in an existing process control system What we can offer you: • Individualized quotation • Calculation of the return on investment • Financing models From us, you will receive only clear and dependable answers!
