In the paper and felt manufacturing industries, energy demand is dominated by drying systems, rollers / calenders, and coating and finishing systems – process heat is required in the form of thermal oil, hot water and steam. Large-scale plants operate continuously worldwide; load profiles are dynamic, and downtime inevitably results in high costs. Heat is essential for drying, setting, smoothing and compacting, as well as for finishing. At the same time, significant waste heat flows are inevitably generated, which are suitable for recovery.
CAW supplies complete energy centers designed for both the supply of process heat and the recovery and utilization of waste heat, which are engineered to ensure reliable availability and uptime in demanding industrial production environments. In addition to thermal oil, steam generators and steam systems, as well as high-pressure hot water and hot air, are required as process media. In numerous processes, shell-and-tube heat exchangers ensure safe media separation and enable efficient heat transfer between heating and consumer circuits.
Any increase in efficiency achieved through heat recovery and utilization is becoming increasingly important: Economizers use exhaust heat to preheat feedwater or to supply hot water and process media networks. Waste heat recovery systems and other suitable downstream heating surfaces significantly increase overall efficiency. For exhaust air streams containing organic components, thermal oxidizer / incinerator systems enable safe thermal neutralisation. If a suitable level of waste heat is available, an ORC system for additional on-site power generation is also a viable option.
CAW designs and delivers system solutions that reliably manage load fluctuations while consistently utilizing valuable primary energy. The goal is a comprehensive heat supply that always ensures production reliability and reduces operating costs.
