The incinerator is a furnace designed for burning dry waste, wet waste, sludge oil and most kinds of solid waste. Combustion takes place in a semi-pyrolytic process with the addition of combustion air in order to achieve smoke-free combustion.
The shredded burnable waste is fed by gravity into the incinerator feeding chamber. Hydraulic operated gate valves feed correct amounts of the solid waste into the furnace and prevent flames and hot air from escaping into the dry garbage silo. Sludge oil burning is available as an option and happens via a sludge nozzle which is fitted in the primary combustion chamber, designed to handle sludge oil with water content up to 30%.
The flue gas inside the burning chamber reaches an extremely high temperature and stays in the secondary chamber for a long time, resulting in a low quantity of particles, and lessened NOx and CO emissions. The flue gas fan keeps suppression in the furnace controlled by continued pressure monitoring of the combustion process.
The incinerator fulfils the emissions requirements set out in Annex VI of IMO Guidelines.
The incinerator is designed for continuous operation and features automatic removal of ash from the ash bed. A screw conveyor discharges the ash from the incinerator and feeds it into either an interchangeable ash container or an ash vacuum system. The ash vacuum system conveys the ash through an ash separator for segregating unburned particles, such as glass and metal, after which the ash is pneumatically conveyed to a bagging unit.
