Marine Waste Incinerator

Marine Waste Incinerator

1. Marine Waste Incinerator Description

The HI-SEA's marine waste incinerator meets the following specifications: IMO Resolution MEPC 244(66)" Standard Specification for Shipboard Incinerators" and MARPOL73/78 Annex Ⅵ，Regulation16. It is designed for on board incineration of ship’s waste oil and solid, it mainly consists of four parts:
Combustion chamber with diesel oil burner, sludge burner, and electric control pane.
Flue gas fan.
Flue gas damper.
Sludge tank with circulating pump and heater.
The incinerator is equipped with single door in front, which are intended for loading of solid waste and ash removing. The slagging door cannot be opened while the combustion chamber temperature is above 220℃. If the incinerator is running in cooling down mode，when the combustion temperature is less than 100℃, the slagging door can be opened after the incinerator stop .
Control box is mounted on the incinerator. The control box is built according to international standards for marine equipment. The operator panel which is located at the right side of the control panel has a touch screen and defined buttons for system starting /stopping and selecting burner modes.
Burning process is controlled by the PLC, monitored by the HMI (Human Machine Interface) and scanned by the flame detector. The combustion chamber temperatures are also regulated automatically by the PLC control system.

3. PLC Program of Marine Waste Incinerator

The PLC program is intended for perform function of solid/sludge incinerator under pre-set parameter and requirement. The PLC program mainly as follow:
 Stand-by for follow function available: manual start/stop sludge oil circulation pump, refers to "operation page" in regard to description of the circulation pump. Manual start/stop the sludge oil heater, refers to "operation page" in regard to description of "sludge oil heater". Open the incinerator door for solid loading. The incinerator will perform automatic cooling if the combustion chamber temperature exceeding the setting of open door in default, refer to data page 2 in regard to description of automatic cooling down. Start-up the incinerator in mode of "solid", "sludge oil", "solid + sludge". Open the incinerator door, slag.
Solid mode description, mainly as follow: Pre-purging. Ignition . Solid incinerating. Post-purging and cooling.
Sludge mode description, mainly as follow: Sludge oil heating, pre-purging, ignition, combustion chamber heating, sludge oil incinerating, post-purging and cooling.
 Solid + sludge mode, the incinerator perform the program of solid mode at first. If solid heat is insufficient, then turn to sludge mode, mainly as follow:
 Sludge heating, pre-purging, ignition, solid burning, sludge burning, post-purging and cooling. Slag of incinerator, closing of the flue gas damper, start the flue gas fan after (No39s)
delay in order to remove ashes. Vacuum adjustment, adjusting of combustion vacuum through the flue gas damper control as program. Stop the flue gas damper action if vacuum deviation is less than
No21，mmWC.
