Conserve energy for fired heaters

Advanced ceramic fiber veneer insulation reduces heat losses and is more resilient

Yoon, H., SK Innovation Co. Ltd.

As energy costs increase, more hydrocarbon processing companies will focus on new technologies to save energy and reduce heat loss. The petrochemical industry uses many fired heaters. These furnaces and heaters consume significant levels of energy. Energy consumption is a major cost component, and it is a determining factor for industry and facility competitiveness. New furnace linings are more efficient than older designs. Advanced linings are also more energy-efficient insulating materials. However, for older design fired heaters, total thermal efficiency is usually low, and hot spot problems occur due to partially worn-out refractory, which is less energy efficient and can increase hea
