1. Marine Incinerator General Description

    When we are planning the program of the marine incinerator, we have followed those rules: meet the requirement of IMO, working stable and without alarm, burning more sludge and save fuel oil. During start up, some conditions will cause flame fail, such as:
    The unit is start with a hot chamber, the temperature of the combustion chamber will reach 970 degree even with a very low sludge dosing, if the fuel oil is shut off, it is possible to cause a flame alarm.
 The unit can be switch over between "sludge mode"/"solid mode"/sludge and solid mode" without restart. There maybe is a hot chamber and very low sludge dosing level, if shut off the fuel directly, maybe cause a flame alarm.
 The suitable start dosing level of the sludge is difficult to setting to meet all condition. Because the water content of the sludge is unknown, if it is setting too higher, will cause black smoke; if it is setting too lower, will cause flame fail. We hope the unit can be running with any water content, and without flame fail. 

2. Marine Incinerator Working Process

    In the program, there is a register, this register is used to decide increase/decrease/shut off the fuel oil. When this register is lower, the fuel is decreased; if this register is higher, the fuel is increased. When the unit is start, this register is set in a middle level. If the chamber temperature if rising quickly, this register will be decrease slowly; if the chamber temperature rising slowly, this register will be increase slowly; if the chamber temperature is drop down, this register will increase fast; if the temperature is over 970gedree and without temperature drop down, this register will be decrease. That mean, the fuel will increase until the chamber temperature arise.
    When the chamber temperature reached 970degree, this register will decrease step by step, and then the fuel will be decrease step by step. How long time will be taken is decided by the current value of this register, and level of the temperature arising. So the temperature of shut off fuel is not a constant. 970 degree is the point to decrease this register step by step. So there is a time delay, When the temperature arising fast, then the delay is shorter; when the temperature arise slowly, the delay will be a little longer, then the system get the time to increase the dosing level of sludge.
