Innovative Project (without investment): 2

Bengal Cement Works

✓ Scope: Due to in apropriate mixing length after HAG outlet duct & recirculation air duct joint, the inlet air through three ducts were having nonuniform heat distribution . The left most duct was carrying most of the heat content. This uniformity was leading non uniforming drying of material & higher specific heat requirement.

❖ Project: Baffle plate installation at Mill inlet duct to distribute uniform heat content to mill through all ducts

❖ Objective: To save thermal energy consumption by effective utilization of supplied heat inside mill

✓Action taken :To resolve the non-uniform temperature distributionat CVRM inlet duct ,a modification with baffles platefixing ( 300 mm width) before the left most duct &between the left & middle duct is done.

.Present Status

❖ When discharge valve is fully open pump is operating at high flow.

❖ Energy saving potential exists by using VFD & Interlock VFD with recirculation flow taking

head requirement of system into consideration.

❖ On a conservative basis – we save 20% power.

Solar Power Utilisation Initiatives taken to increase Generation

✓ Tilting solar module two times in a year with trials at different angle on every season.

✓ Cleaning entire solar modules in 4 cycles in a months for summer and winter season instead of 2 Cycles suggested by OEM.

✓ Planting tress like water melon, pineapple, aloe-verra for cooling of solar modules during summer season.

✓ Water spraying system arrangement done for one inverter on top of the module for cooling purpose.

❖ Initiatives to reduce carbon emission :▪ Installation of 5 MW solar PV power plant▪ Reduction of total electrical energy consumption▪ Reduction of thermal energy (Kcal/Kg)▪ Improving clinker factor in cement.▪ Reduction of internal vehicle fuel consumption by use of

battery driven vehicles.▪ Reduction of raw material reciept vehicle fuel

consumption by change of inward transport mode fromroad to rail .

▪ Enhacement in production of Composit Cement in placeof PPC- an approach towards sustainability.

Use of battery operated vehicle for plant internal transport saved 20,000Kg CO2 emission per year
