Handling fuel shift deftly for a polyester major
One of the largest producers of polyester fibres in India has a plant located at Patalganga in the state of Maharashtra. To deal with the rising prices of hydrocarbon fuels, the customer decided to switch to coal for operating its utilities. Catering to this requirement, the Boiler & Heater (B&H) division of Thermax commissioned two units of 15 MMkcal/hr coal-fired Dowtherm vapourisers for the customer.
Dowtherm vapouriser is a preferred technology in manufacturing heat sensitive products such as fibres as it provides a more uniform heat source and precision temperature control. Thermax being pioneers in this application, customised the design for coal-fired vapourisers successfully.
An atmospheric fluidised bed combustor burns Indonesian coal and is connected to a radiant and convective tube bank which generates the Dowtherm vapour. This solution will not only help bring down fuel costs for the customer but also recover their investment within a short time.
