This oil may be from excess compressor cylinder lubrication, from faulty oil scraper rings, or may even be suspended oil vapor contaminating the engine room atmosphere and drawn in at the compressor suction. Oil discharge is kept to a minimum by draining the after cooler, air receiver and starting system. If small quantities of lubrication oil do get passed into the starting air system, they will deposit as thin moist film over internal pipe surfaces but are not readily combustible. If a cylinder non-return valve leak while the engine is in operation, some hot gas, possibly with unburned fuel and cylinder lubrication oil, may be blown through the valve to the adjacent air manifold. With further heating from the leaky valve, this, together with the already deposited oil film, will carbonize and form incandescent carbon. If starting air is applied to the system while still hot, the high pressure air coming into contact with the burning carbon may cause an explosion. Such an explosion will cause a flame to pass back through the air start pipe system, evaporating the deposited oil film and igniting it in the presence of air. Very high velocities and shockwaves are generated which may rupture pipes and fittings. Alternatively, if excessive oil has entered the air start system, a mixture of air and oil droplets may be discharged through the open cylinder non-return valve during starting. This spray may ignite due to high temperatures in the cylinder, causing a flame through the still open valve to the air manifold.To prevent an explosion, air start valves must be correctly maintained and lubricated to ensure correct timing and free movement with positive closing. Oil in the system must be kept to a minimum, pipe lines must be drained and cleaned internally when necessary and oil discharge from air compressors must be kept to a minimum by good maintenance.87. The passage is mainly about .A. crankcase explosionB. scavenge box fireC. starting air pipeD. the danger of explosion in the starting air system88. According to this passage, if the cylinder non-return valve were not leaky, .A. an explosion would not be causedB. there still would be a danger of explosionC. oil would not deposit in the air pipeD. pipe lines would not have to be drained89. Which of the following is NOT mentioned in this passage?A. There may be oil vapor in the engine roomB. Pipes and fittings may be damaged if explosion takes placeC. The cooler should be drainedD. Bursting caps must be fitted90. The word "spray" (underlined in the third paragraph) means .A. oil mistB. hot gasC. injectionD. fuel oil第三组：The sewage treatment system must be capable of discharging an effluent that comes within thelimits of the tests. Sewage can be treated biologically so that it may be discharged with minimal damage to ecosystem. Biological treatment involves the use of living organisms to treat the sewage within the sewage treatment plant so the liquids and sludge discharged are within the standards specified.Biological treatment plants are usually built up as a module and consist of various sections.Waste matter collected from the ships sanitary appliances is led through a sanitary piping system to the treatment module. The solid matter is broken up by passing it through a screen or a series of revolving cutters. The broken up solid material, together with the waste liquid, passes into a tank containing bacteria which require oxygen and a nutrient to propagate. The nutrient is contained in the solid waste material, and oxygen is supplied by bubbling compressed air through the broken up waste. The propagated bacteria change the waste material into a sludge by aerobic digestion. The sludge is finally treated to kill the coliform bacteria before it is passed overboard.When a biological sewage plant is started up, such as when activating a new ship or after cleaning out the tank, a pellet containing bacteria is introduced into the tank. It takes approximately one week for the bacteria to propagate and make the system fully effective. The choice of sanitary appliance cleaners requires extreme care, as many cleaners are toxic to the active bacteria. Once a biological sewage plant is made active it should not be shut down. If it is it will have to be reactivated again because the bacteria will die without a supply of nutrients and oxygen.Bacteria that require oxygen for their survival are referred to as aerobic. Aerobic bacteria are normally used in ships' sewage treatment equipment. Other forms of bacteria that do not require oxygen are referred to as anaerobic. Anaerobic bacteria are used in shore based sewage treatment works where methane is obtained as a by-product for use as fuel.91. This passage is mainly about .A. sewage treatment methodsB. the various sections of a sewage treatment plantsC. biological sewage treatment systemD. how the sewage treatment plants are started up92. Biological treatment may use __ to treat sewage.(1)living organisms (2)chemicals (3)additivesA. (1)B. (2)C. (3)D. (1)(2)(3)93. Sanitary waste matter will .(1)pass through a screen or cutters (2)come into contactwith the bacteria in a tank (3)be discharged, normally without bacteriaA. (1)。
