With good management, to facilitate subsequent starting from cold, the fuel system of large boilers will have been flushed through with diesel oil when the boiler was on light duty immediately prior to being secured. When burning such diesel fuel it is essential for safety that only the correct (small) burner tip should be used. It should be kept in mind that if fire does not light, immediately shut off fuel and vent furnace.Complete ignition of fuel in the furnace is essential. The burner flame, the smoke indicator and the funnel should be frequently observed. With satisfactory combustion, the flame should appear in candescent （白热的）with an orange shade at the flame tip, and a faint brownish haze should show at the funnel. If on first ignition the flame is uncertain, badly shaped and separates from the primary swirler, momentary opening or closing of air register may correct. 75. Small package boilers will use _______ while being lit up.A. the usual source of oilB. fuel oilC. diesel oilD. mixture of fuel oil and diesel oil76.

In such cases, access to the Restricted parts of the Plan relating to the non-compliance is exceptionally allowed, but only with the consent of the Flag State, or the master. If the master, in his professional judgment, believes that such "clear grounds" exist, and allowing access to relevant sections of the Restricted part of the Plan might resolve the situation, such access can be exceptionally granted. However, this should be immediately reported by the ship to the Company Security Officer (CSO). If access to the Restricted part of the Plan is denied by the master, this should be immediately reported by the Company Security Officer for guidance and reference to the Flag State.The Confidential part of a SSP cannot be subject to non-flag State inspection unless otherwise agreed by the contracting governments concerned. Any such request or demand by port state officials to view sections of the Confidential part of the Plan will be immediately reported by the ship to the Company Security Officer for guidance and reference to the flag State before any details are revealed to non-flag State officials. The Confidential provisions, which from an integral part of this Plan, are held by the Ship Security Officer (SSO).69.After a security incident, the revision of the SSP will made by .A. file CSOB. the SSOC. persons duly authorized by the Ship's Flag State AdministrationD. information not given70.

Port StateB. Flag stateC. The CSOD. The Administration第二组The only attention that heat exchanger should require is to ensure that the heat transfer surfaces remain substantially clean and the flow passages generally clear of obstruction. Indicationthat undue fouling is occurring is given by a progressive increase in the temperature difference between the two fluids, over a period of time, usually accompanied by a noticeable rise m pressure loss at a given flow.Fouling on the sea-water side is the most usual cause of deterioration m performance. The method of cleaning the sea-water side surfaces depends on the type of heat exchanger. With shell-and-tube heat exchangers, the removal of the header covers or, in the case of the smaller heat exchangers, the headers themselves, will provide access to the tubes. Obstructions, dirt, scale etc., can then be removed, using the tools provided by the heat exchanger manufacturer. Flushing through with fresh water is recommended before a heat exchanger is returned to service. In some applications, such as piston oil cooling, progressive fouling may take place on the outside of the tubes. Most manufacturers recommend a chemical flushing process to remove this in situ, without dismantling the heat exchanger.Plate heat exchangers may be cleaned by unclamping the stack of plates and mechanically cleaning the surface of each plate as recommended by the manufacturers. The plate seals may require replacement from time to time and here the manufacturers' instructions should be closely followed.73. By which of the following indication, can we conclude that the lube oil-sea water heatexchanger is unduly fouled?A. the heat exchanger lube oil inlet temperature loweringB. the heat exchanger sea-water outlet pressure riseC. the heat exchanger temperature difference between lube oil and sea water increasingD. the heat exchanger pressure difference between sea water inlet and outlet decreasing74. What is the most usual reason for the fresh water-sea water heat exchanger fouling in the seawater side?A. lube oil sludge accumulating in itB. dirt and scale etc., formed on the surfacesC. deformation of the tubes and the shell or the platesD. lube oil leakage into sea-water side75. According to the passage, it is recommended that the heat exchanger oil side be cleaned by .A. flushing with chemical solvent without being dismantledB. brushing mechanically after being disassembledC. flushing with fresh water onlyD. flushing with clean oil only76. According to the passage, which of the following statement is not true?A. the heat exchanging surfaces should be kept substantially cleanB. the heat exchanger flow passages should be clear of obstruction generallyC. seals for the plate heat exchanger needs to be renewed oftenD. the cleaning process of the plate heat exchanger should be done following our experiencesonly三、中译英（共2题，请将答案写在答题纸上）77. 在船舶以主机“正常全速”运行时，尽管速度设定及压力正常，转速逐渐下降，驾驶台控制立即转换至机旁控制。
