章節(jié)摘錄

　　Unit Eight　　Drax Coal-Fired Power Station　　Steam Drum　　The steam drum is an all welded cylindrical construction supported by two Uslings from the steelwork. The drum was manufactured in one piece at the factory and was transported to the site by sea. It has a length of 30.40 m and an internal diameter of　　2.29 m. Its weight with the internal fittings is 335 t.　　Four rows of 65 conical cyclone separators axe fitted in the drum and above each separator is an inclined primary scrubber. Secondary scrubbers are fitted at a higher levelclose to the saturated steam takeoffs. The drum is made from high tensile steel and nowelding is permitted on the drum after it has been stress relieved.　　Apertures in a girth baffle allow the combined steam and water mixture to enter　　cyclone separators which are arranged in pairs, in two rows along the front and the rear of the steam drum. The steam and water mixture enters each cyclone body tangentially and whirls around the inside of the cylinder producing a powerfull vortex, within which a positive separation of steam and water occurs. The steam collects in the centre and passes out at the top, whilst the water moves downward in a helical path and passes back into the drum water space for recireulation through the furnace walls. The saturated steam flows upwards through the primary inclined scrubbers which remove water residue that may be carried over by the steam after leaving the separator. The steam then passes through secondary scrubbers, fitted at the top of the drum, which provide a final separation of　　water from the steam before it leaves the drum and flows into the superheating circuits. Draught System.　　The draught system comprises two forced draught(FD) fans, two induced draught　　(ID) fans, two rotary airheaters and three elect.w-static precipitators. Air for combustion is supplied to the bumer registers by the two FD fans by way of air preheaters where the boiler flue gases heat the incoming air. The effluent gases are drawn through three electrostatic dust precipitators by the ID fans which then discharge the gases to the chimney. The furnace is balanced by the FD and ID fans to maintain a pressure just below atmosphere.　　The FD and ID fans are mechanically similar, the ID fans having a higher maximumduty specification. The fans are electrically driven at constant speed and the air or gasvolumes are controlled by radial inlet guide vanes.　　Gas air heaters are used to provide a means of heating the air supplied to the furnacein order to assist combustion and provide for a more economical use of fuel. They aresupported by the main boiler strnetural steelwork at the firing floor level, and located atthe rear of the furnace enclosure,: one fitted on each side of the boiler beneath the gasoutlet flues.　　The air heaters are of contra-flow design, the combustion air from the FD fanspassing upwards through the units to the burners, via the hot air duets, whilst the fumacegases from the boiler outlet flues pass downwards through the units to the precipitators.The two streams, which flow through diametrically opposite segments of the rotor, areseparated from each other by a small blanking section fitted with sealing plates which forms a division between them.　　Each of the air heaters is fitted with its own combined sootblowing and water washing gear, fire detection and fire fighting equipment and a pressure fed oil system for lubricating the rotor bearings.　　The rotor, which is 14.4 m in diameter, is the central part of the air heater and contains the heat transfer matrix. Each rotor has a nominal heating surface of 51 826 m2. Radial plates extending from the hub divide the rotor into 24 sectors which in rum are sub-divided at the hot and intermediate ends by sector division plates which strengthen the rotor and carry the hot and intermediate end element containers. At the cold end of the rotor, grids welded between the radial division plates perform the same duty as the sector division plates, but enable the cold end element containers to be radially withdrawn from the air heater. The weight of the rotor is carried on the underside by a spherical roller thrust bearing whilst at the top a spherical roller guide bearing is provided to resist radial loads.　　The rotor is driven by a small electric induction motor coupled to the rotor hub　through a double worm reducer and spur gearing.　　Precipitators　　Three electrostatic precipitators per boiler are fitted in each gas discharge line to　collect dust from the boiler flue gases. The precipita~rs achieve a collecting efficiency of 99.5% with a gas inlet ternpemture of 120 ~C and volume per boiler of 803.2 m3/s. Dust-laden flue gases are directed through the zones of each precipitator in which discharge and collecting electrodes are situated. A variable high voltage de curium is supplied to the electrodes.　　The precipitators, which are mounted on steel support structures above round level, comprise six rows in series of dust-colleeting plates forming muhipandlel gas paths and with discharge dectrede wires suspended vertically within these paths. Boiler flue gases are directed by baffles in the inlet flare to flow evenly through the precipitator via gas passages formed by the spaces between the eolleeting plates. The cleaned gases are extracted by the ID fans and vented to atmosphere through the station chimney. The dust which aceuraulates mainly on the colleetlng plates but also on the discharge wires is　removed at　intervals by mechanically-rapping the plates and wires. The dislodged dust falls into hoppers suspended below the precipitators and supported by the steel structure. Aecumulated dust in the hoppers is removed by the dust disposal plant to which the hopper outlets are connected.　　The generation and control of the high voltage (HV) systems, rapping control　　systems and heating systems are located at ground level on the gas inlet side of the precipitators.　　……
