|
For manufacturing Industries, energy accounted for up to 38% of costs. Hence better energy management and greater efficiency in manufacturing are therefore going to have significant positive environmental and cost saving impacts. Recycling of Heat is one way to mitigate the loss of resources viz. electricity, fuel, raw materials etc. A case study was undertaken at a company viz. HEG Ltd. where carbon rods are produced from graphite powder. These graphite powders are dried by flowing dry & moisture free air over them for pneumatic conveying the powder from one process to another. The flow of high pressure air from compressor is generally hot. This heat is used to heat up the cold air from the separator by introducing an additional air to air Heat Exchanger. Thus the modified system heat up the dry air for pneumatic conveying the graphite powder. Thus the system efficiency is improved. |
