The core of the pre-heater, the heat exchange surface, is composed of several hundred tonnes of metal plates known as elements. For manufacturing element at LTH, we are equipped with an automated line designed, manufactured and installed by our JV partner Howden, Spain. The line is covered with safety and acoustic guarding. The production line is designed with quick changeover of profile rolls for various element profiles. Installed line can produce 8700 MT of elements/ year.
LTH has a range of element profiles rollers to suit the requirement of customers, both for new projects and for their after-sales requirement. For new projects element profiles are chosen by our Engineering Team to suit the gases and particles passing across the elements to get the maximum performance. They are packed in compact, open-sided containers that bring the element edges close to the rotor's radial plates so that none of the rotor space is wasted.
Element packing presses and packing procedures involved:
The facility has steel coil storage systems to store variety of coils. Steel sheets are the input material which passes through the profiled roller, the profile gets generated on steel sheets and this cold rolled profile cuts into desired length and filled into the empty container which is pressed and welds to top cover plate.
After complete inspection on the basket it is sent for packing. Rust preventive packing is provided with tubular palletizing which ensure no damage occurs to the elements and basket in transit.
