Melco accomplished the leading position by anticipating customer requirements and recommending the most suitable type of ash handling system to them. An important consideration whilst selecting the system is the type of ash to be conveyed. This is because ash types have different compositions due to a combination of differing combustion methods, fuels used, boiler designs and flue gas treatments. Other factors that help in the decision making are the boiler size, availability of the ash disposal area, pollution control needs and the need for fly ash utilization. Fuel types, solids or liquids that are used in the production Thermal Power Plants or industrial combustion processes give rise to ash types that are different from each other. The main categories of ash are bottom ash, fly ash, mill reject ash. Bottom ash, which accumulate at the bottom of the boiler in the form of lumps, requires mechanical, pneumatic conveying or hydraulic handling systems. Fly ash, which is more volatile, gets deposited at the bottom of the ash hoppers in the equipment downstream of the boiler. Such electrostatic precipitators, stack hoppers, air pre heater, duct hoppers, and economizer pneumatic conveying system or hydraulic systems are used for the removal of this ash.
