Technical description
Overall system function description
The Team Tec Incinerator type OGS 400C is designed for on board incineration of ship’s waste oil and solid refuse and consist of four main parts:
· Combustion chamber w/ diesel oil burner, sludge burner, pilot fuel heater & electric control panel.
· Flue gas fan.
· Flue gas damper.
· Sludge tank with circulating pump and heater.
Combustion chamber
The combustion chamber is a circular chamber, equipped with a loading door and an ash door, which can be opened only while the incinerator, is not burning. The control system will prevent the doors from being opened before the set temp for cooling is passed. The trash is ignited by heat from the burner.
A secondary air damper is located next to the loading door, that open as required.
The flue gas outlet is located at the top of the chamber for most efficient use of the flames. The flames follow a corkscrew pattern towards the bottom and continue rotation upwards in the centre of the combustion chamber. Remnants of particulate matters in the gas flow are neutralised by the burner so it is ecologically safe. As the fumes leaves the chamber, cooling air drawn from the lower part of the casing in mixed with them to bring the temperature down to approx. 340°C before it sucked out by the flue gas fan and blown out the smokestack.
The burning process is monitored by the PLC and scanned by a photo resistor. The temperatures are also monitored/regulated automatically by the PLC control system. A sight glass in the loading door is equipped for the operator to be able to watch the amount of trash in the chamber and the function of the system.
The combustion chamber is of steel construction, lined with specially designed refractory blocks insulated on the outside with 50 mm insulation. The refractory material is made of a low cement/high alumina quality being slag resistant and having very good thermal shock resistance. A double steel casing with a cooling jacket forms the outside of the combustion chamber.
The combustion chamber is equipped with a two-stage diesel oil burner and a steam/air atomising nozzle for sludge. On the same wall a bracket/dip tray for sludge burning equipment is mounted.
The D.O. burner has 2 stages, which are automatically regulated by the PLC. In addition there is a third stage for sludge burning using steam or compressed air for atomising. The sludge burner allows particles up to 4 mm to pass through. The burner is monitored by the PLC and has built in primary air fan and diesel oil pump.
The electrical control panel is installed on the incinerator and it contains fuses, starters, PLC and operator panel. The electric panel 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 LCD display and keys for selecting burner modes.
Flue gas fan
The purpose of the flue gas fan is transportation of the flue gas from the combustion chamber and the fan creates negative pressure in the furnace. The same fan draws ambient air through the cooling jacket on the combustion chamber and the hot gas from the furnace is diluted with the cooling air at the flue gas outlet on the combustion chamber in order to reduce the temperature approx. 340°C.
Flue gas damper
The automatic flue gas damper will adjust the gas flow in the flow gas duct and it is being controlled from the electric control panel, which is sensing the negative pressure in the furnace and regulating the pressure to set level.
Sludge tank with steam heater
The TeamTec Sludge tank is meant to function as a daily service tank for sludge to the incinerator. A transfer pump can be used to fill the tank, and be connected to the “high level” switch, which stops the pump when the tank is full.
A heater, controlled by a thermostat, will keep the sludge temperature around the set point (60 to 90 °C). (With temperatures above 60°C, regulations require tank to be insulated or guarded with metal screen).
Two drain valves (sample points) are mounted on the tank to check the sludge level in the tank. The lowest one is meant to use for draining off the water.
A circulating pump is mounted on the tank. The pump transports the sludge to the incinerator and as a return line to the tank is provided, a good mixing of the sludge and water is guaranteed.
A low level switch on the tank will stop the circulating pump and heating when the level has reached a minimum.
An indicating light for heating is placed on the junction box on the tank.
