Operation & Maintenance of Power Plants

Extending discharge plant life and increasing throughput In many instances, the benefits of
espite the reduction in its use in western countries, coal is still a major fuel worldwide. This global
trade poses a major challenge to shippers in handling the various sizes, types and blends of coal, and also in coping with the abrasive characteristics of the fossil fuel. The problem is that coal is high in silica,
a mineral that causes erosion and wear, in the plant and equipment used to process it. In the pressurised world of bulk
carriers, where coal is handled in quantities of millions- of- tonnes per year, the ramifications of this problem can be very serious, resulting in extended ship layovers if not addressed. Consequently, it makes economic sense
to take appropriate measures to protect against the sliding friction and impacts that cause wear. Wear protection is the process of
coating or lining process plant and equipment, such as bunkers, pipework, chutes, cyclones, valves, with ceramics, metallics or polymers to extend their life. Kingfisher Industrial has calculated that,
on average, users of its wear protection systems benefit by a factor of 5 times their initial outlays, with many installations providing wear life of up to 20-years following appropriate wear treatment.
protecting plant are threefold: in addition to protecting against wear, the low friction nature of the lining material reduces energy usage and allows a greater volume of material to be loaded or discharged, resulting in reduced demurrage costs for port side facilities, and limiting the duration bulk handling vessels spend discharging difficult cargoes such as coal. “The choice of liners to aid discharge
and protect structures is an important decision, because not only will it maintain the asset value of the vessel handling equipment. It will also ensure demurrage costs are kept to a minimum by enabling continuous discharge at the desired rate of conveyance,” said Kingfisher MD, John Connolly. Selecting the right liner materials,
hopper design and pipe installation can prevent the need for replacement and maintenance for up to 20- years. ●
