Cremation Industries
Cremation is the practice of final deposition of the deceased. In earlier days, cremation was an open – air pyre. However, in modern days it is carried out in a closed furnace at a crematorium. This process is known as flame cremation. Here the body of the deceased is placed with due care into a specialized equipment called a retort, which is fuelled by either natural gas or propane. When in use, the interior of the retort reaches temperatures up to 1300°C. The intense heat helps reduce the body to dried bone fragments. The remains are put into a special processor that pulverizes the bone fragments. These are then handed over to the kin as ashes.
Since the process of flame-based cremation generates numerous harmful pollutants which have severe effects on the surrounding environment and human health, the practice of Alkaline Hydrolysis have come to light. This process uses potassium hydroxide or lye to disposal of remains. The deceased is placed in a pressure vessel which gets filled with a mixture of water, potassium hydroxide or lye. This mixture is heated using gas to a temperature of around 160°C. What remains is bones and metals (in cases of operated bodies). The bones are then sent for pulverization, post which they are handed over to the kin in an urn. The metals are sent to factories for re-cycling.
Textile industry is known to be a great contributor towards the economical growth of any country. However, it is said that emissions from textile factories are the second biggest cause of pollution in the world.
Considering the above, gas is the cleanest and economical fuel used in a variety of applications namely bleaching, dyeing, temperature and humidity monitoring in storage/ warehouses, drying, singeing, tentering, crabbing, and heat-setting.
Drying: Air required for drying can be heated directly (from fuels, electric resistances and quenching processes) as well as indirectly (via heat exchangers). Direct air heating using contaminating fuels such as oil, diesel make the air susceptible to contamination (from sulphur compounds, soot, heavy metals and unburnt compounds). On the other hand, using gas meets cleanliness requirements for numerous processes. Gas is also used as a heat source for other processes e.g. quenching.
Singeing: Also called gassing, this process is used to deliver an even surface by burning off projecting fibres, yarn ends, and fuzz. This is done by passing the yarn/ fibre over a gas flame or heated copper plates at speed necessary to burn the protruding material without harming the material. Gas powered singeing machines can eliminate pilling of polyester blends, improve the fabric surface and retaining softness as fabric tension is controlled throughout, in accordance with the type of fabric being singed. It can also be used for singeing single yarns, twisted high-grade yarns for voiles, poplins, mercerized knitting yarns, embroidery yarns and sewing threads.
Features: Gas singeing machines have excellent safety measures. The burners, control systems and auxiliary equipment are constantly monitored by a safety system which automatically turns off the machine in the event of any malfunction.
Its flexibility with individual spindle drive helps to increase efficiency.
It provides flame with high mechanical and thermal energy to quickly burn thermoplastic protruding fibres without any molten beads formation.
