【正文】 ng on/off and speed level. Mediumspeed Coal mill explosionproof steam from a wind room, _, _ separator casing into the ground to prevent the mill explosion in the process of starting and stopping. Mill load is to accept current signal to the coal control proportional pressure relief valve size, change of hydraulic accumulators and hydraulic cylinders, to achieve load changes. Sealed Air for coal pulverizer drive, Rod bearings, roller. Cold wind of a user with a sealed air blower air, sealed air, ground coal to a cold wind. Turbine sealing oil primary oil source is airside seal oil pump, the first alternate oil sources (mainly alternative oil source) is the main oil pump of turbine. When the primary oil source failure, the first spare source automatic put into operation. Second alternate oil sources primary alternate supply AC electric sealing oil pump on the fuel tank, when the turbine speed is less than 2/3 rated speed or first alternate source failure occurs, the second spare source automatic switch. Third alternative oil source is provided by DC sealing oil pump. Main fuel tank exhaust throttle should be located 2 steel closing door operation handwheel locking is not allowed and obvious warning signs should be hung. Steam engine room caught fire, when it threatened to tank or fuel system, shall immediately destroy the vacuum emergency stop, and turn on the tank accident put the throttle, speed and control on oil should be appropriate, to ensure that the rotors lubricants are not interrupted before static. Shaft seal overflow overflow to 8 the low pressure under normal conditions, when 8 the low pressure overflow when the outage to the condenser. Sliding pressure operation of deaerator may avoid deaerator steam source for throttling losses. Normal operation of steam turbine steam distribution mode for steam distribution nozzle. After the turbines stopped, if the rotor cannot rotate for a short time, rotor _ __ under bending, highest in __ ___ highs at this point rotor should be reset, close the hydrophobic __ __ cylinder, keeping __ up and down temperature difference between cylinder _ monitor rotor __ __ deflection, when after you verify that the rotor is, and then manually turning 180 186。t move, do not forcibly barring ___ __, but can not turn __ forced _ or turning the crane broke. Stop turning _8__ hours later, to stop the lube oil system. Condensate pumps due to transportation of saturated water, the pump is most prone to cavitation __ ___, therefore is posed of __ inducer __, and at the time of installation ensure the pump inlet has some highly ____ __ intrusion, and design _ export recycled __ tubes, also in order to solve this problem. When the condenser when the water level is too low _ setting up __ pumps are turned on, into the air to prevent the pump design __ ___ seal water, prevent the pump output is not normal. ... Threaded tube within a water wall, deterioration of heat transfer does not occur. X turbine cold starts, heat transfer of steam to the cylinder wall is based on condensation heat transfer and convective heat transfer in two ways at the same time. (X) the furnace higher excess air coefficient, smaller chemical heat loss due to inplete bustion. (√) Boiler of soda expansion is inevitable. √ Startup incorporations, boilerDC operation, adjustment of main steam temperature control in a coalwater ratio between points. √ A single swirl burner burning adjacent burners are not required to support. Swirl burners with different rotation direction will affect the boiler steam temperature and load parameters. X boiler steam flow is divided with double builtin startup separator designed for munity process. √ During bustion of pulverized coal in boiler, oxygen content, the lower the NOx is produced more. √ When the gaswater ratio imbalances, oncethrough boiler steam temperature at each point in the trip will change, and closer to the pop tour entrance, inertia and hysteresis temperature change is smaller. √ In disguise near the heat transfer coefficient of steam increases to a maximum at first and then quickly lower. √ Control of startup separator outlet steam temperature, that controls the boiler heating and evaporation, thermal heat distribution. (X) as the direct current requirements for operation of the boiler feedwater quality was much higher than that of drum boiler, in oncethrough boiler startup process, therefore there is no need for furnace washing of Silicon. () UP the boiler is subcritical and supercritical parameters can be used in the furnace, working one or two times, connecting multiple hybrid, has a higher mass flow, suitable for large supercritical pressure oncethrough boiler. (X) thisis the biggest characteristic of evaporating heating surface of boiler tubes were repeatedly increased the vertical tube screen, using mixed header and not in the middle of heated drop tube in series to each other. Due to the temperature difference between different Panel next to the pipe, thermal stress, membrane water wall of seam damage. Check (√) the spiral water wall in addition to import and export is located outside the box, no mixing header in between, due to its arrangement of furnace size does not affect, even heat heat low errors will not result in the uneven distribution of steamwater mixture. (X) supercritical and subcritical case, when the water is heated to the appropriate phase transition temperature under pressure, all vaporize into steam. (X) direct current boiler, water into steam steamwater twophase region does not exist. The experienced heating and hot water into superheated steam in two stages. (√) Phase transition under supercritical pressure, when all water vaporized into steam temperature, also known as the critical temperature. Different pressure phase transition temperature. (X) in the area near the phase transition point, the specific volume of refrigerant to rise sharply, and the greatest specific heat at constant pressure. (√) Under su
