Under the Chongqing Municipal landscaping management standards and the technical specifications of urban landscaping projects adopt the following approach working mechanism. Will this unit dedicated to the conservation section is divided into four groups: the trees and shrubs to the conservation group (responsible for measures such as the shading)。there? After ignition, bustion should focus its attention on what? Reducing boiler hot loss measures? DCwhat are the main characteristics of the boiler? Boiler steam after Bao Biwen how? when shutdown to control steam drum wall temperature difference? From a run standpoint, what are the main measures to reduce coal consumption for power supply? Talk about how to control the water level? Generator after splitting, 6KV why to promptly exit the standby power switch? Why the current transformer secondary side in the operation are not allowed to open? Why synchronous generator excitation circuit of the degaussing switch can be changed into a lively breaker? Generator stepup process, why the rotor and stator currents to monitor? Why are rotor one point ground prone to 2nd after ground? Try 380V discussed following the grounding of auxiliary power system, wiring for threephase fivelimb terminal of PT secondary voltage change? Generator inplete phase operation principle is what? Yn,d11 (Y0/11) connection of generatortransformer systems, generator openphase running any help? Why to install 100% stator grounding protection for large generator? Why does not allow running secondary short circuit? Generator excitation, excited, what is the of the overexcitation limit? Generator loss of excitation in the running, what is the impact on the system and the generator itself? Anticuozhong on the prevention of excitation system of generator caused by fault what damage? try discussing what are the measures of improving power system dynamic stability? What is a switching operation of the electrical equipment? main content switching operation of power plants and power systems are there? Try discussing malignant electric misoperation, which misuse personal, most of the equipment? Switch service power fast cutting device in several ways? in the alternate to the State, the standby power switch refused to deal with? Try discussing switching operations should focus on preventing misoperation accident? New operation or after majorrepair of transformers why test? Try discussing steps measured with a Megger insulationresistance of electrical equipment? Lu method is used to find DC grounding considerationarewhat? when there are two point grounding with the polarity should be ... supercritical supplementary questions, blank mini disk can be divided into manual and two oil turbine。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. C
