Akzo Nobel Contract Report Case Study
Akzo Nobel, a global paints and coatings manufacturer with operations in over 80 countries, were seeking sustainable methods of reducing their Slough production plant’s annual emissions, as well as its fuel and running costs.
Details
In the production plant, Akzo Nobel use a gas fired burner unit to heat a heating oil (Thermex) which is pumped through a heat exchanger transferring the heat to the resin. During the batch process, depending on the resin being produced, the batch temperature can be as high as 380°C.
Their existing burners and combustion system was a mechanical linkage based setup with inefficient burners that were costly to operate Hence, they chose Limpsfield to replace these with a complete combustion package - two highly efficient LCN0123 burners firing Natural Gas and #2 Oil.These high performance burners came with custom-made Autoflame microprocessor burner controls, allowing the regulation of the amount of fuel and air passing through the burner to specific ratios using the Autoflame Micro Module control system. The burners and controls vastly increase the combustion efficiency, whilst at the same time reducing harmful emissions.
The project was predicted to achieve annual fuel savings of over 12%, as well as limiting the 02 to 3% throughout the firing range. As a result, significant reductions in emissions as well as fuel costs were evident with much lower maintenence downtimes.
