Building materials industry: Robust systems for high-temperature process heat and waste heat recovery
Heat for drying, processing, hot gases and continuous production lines
Highly variable throughput rates, dust and other environmental impacts, as well as thermally intensive manufacturing and processing operations, are characteristic of the building materials industry. Drying plants, kilns, moulding/vibrating tables, processing plants and hot gas lines must be supplied with a stable heat supply at all times. In view of existing and increasing requirements regarding emission limits and decarbonisation, fuel flexibility and energy efficiency are equally crucial factors: energy is the dominant cost component in this sector. Plants must be built to be uncompromisingly robust and consistently enable long operating cycles without interruption.
CAW designs and supplies complete systems to meet all requirements for process heat and heat recovery. Thermal oil systems are suitable for temperature control tasks and processes that require a defined, uniform heat supply and precise temperature control. For direct hot gas or hot air applications, CAW designs suitable combustion systems to ensure a reliable supply. As combustion processes naturally generate exhaust gases, the utilisation of waste and residual heat is always a key factor in improving economic efficiency. Economisers and shell-and-tube heat exchangers recover this heat and feed it back into the system as hot water or via a heat transfer circuit.
Where combustible waste materials or other suitable fuels are available, incineration plants can provide a cost-effective source of heat. CAW designs combustion systems to ensure that even widely varying fuel qualities can be reliably managed. In manufacturing and processing operations involving exhaust air streams contaminated with organic or other odorous substances, TRO/TAR systems safely oxidise the exhaust air components whilst simultaneously enabling effective heat recovery. Where a constant temperature level is maintained, an ORC system can serve as a supplementary means of decentralised power generation.
