Rubberized coir mattresses is formed from coir and latex rubber is an industrial process. Heat delivery of 0.5 to 1 million kilo cal boilers ( either steam or thermic fluid, operated by fossil fuels ) are needed for process heat in the production line . The considered factory uses 0.5 million kilocal capacity thermic fluid burner which uses around 900 – 1200 kg fire wood per hour to heat thermic fluid for transferring heat to different thermal applications mainly at 4 stages namely:
1. Drying out moisture in coir coil by placing them in an enclosure heated to 70
°C.
2.Sheet forming machine in which air is heated to 70 – 80
°C
3.Vulcanising machine where air is heated to 120
°C.
4. Calendar pressing sheet by contact heat at 150
°C.
