Heat recovery and mechanical chimney draught control for glass production

glass production cover

Companies are constantly trying to improve the efficiency of their production process. When a company endeavors to exploit its resources fully, it naturally results in a reduction in production costs. Recovering waste heat enables the company to further for improve efficiency by exploiting waste heat from the process. In many production companies, the heat emitted in form of combustion air, process air, or steam is not exploited, and as such, a significant energy source is often wasted. Heat exchangers from exodraft are quite efficient at converting excess thermal energy into hot water, which may then be stored in buffer tanks for future use, for instance, or used for numerous other purposes.

Only the sky is the limit. exodraft also delivers mechanical chimney fans that always maintains constant draught independent of weather conditions.

The glass manufacturing process involves high temperatures at several different points, right from the initial mixing and melting of raw materials to conditioning and forming the glass. Constant draught enables a uniform product flow.

Heat recovery systems from exodraft can be used in several phases of the glass manufacturing process, such as when raw materials are melted in an oven, where the temperature reaches 1550°C. 25-30% of the heat content in the glass manufacturing process consists of exhaust gasses that are discharge during several phases with temperatures of 400-500°C. During conditioning and forming of the glass, the temperature ca reaches 1100°C, rarely going below 800°C. All these phases in glass manufacturing creates the possibility of heat recovery, and if you exploit these possibilities, you can also realize great benefits. The recovered heat can be transferred and reused in the manufacturing process, which reduces energy consumption. For instance, the recovered heat can be used for cleaning equipment or manufacturing systems. If the energy is used in the process, it will result in reduced production costs.

First, our engineers use our OptiCalcHR software to help your company quantify the amount of heat that can be recovered. We not only calculate your cost savings; we also predict your reduction in CO2 emissions. The process involves chimney draught analysis and establishing the recovery potential by using datalogging.
