【正文】 eam 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 supercritical pressures, the specific heat of water increases with temperature, the specific heat of steam decreases with increasing temperature. (√) Under in subcritical oncethrough boiler evaporating heating surface of multiple values that appear unsteady flow, the main reason is a low enthalpy of evaporating heating surface inlet water. So in thelowload operation must restrict entry low enthalpy of water. (X) the flowofrefrigeraevaporating heating surface of ambiguity existonlyinspiralwallverticatubecoilsdnotexist. √ Evaporation ...education and training. (3) technology can guide operators work on the business, ready to solve engineering problems. (4) the text clearly technical problems with the cards on the table and retain the original information to the persons concerned, good technical approval and visa in a timely manner. 4, data administrator responsibilities (1) is responsible for all the project files, data collection, production, binding, collating, storage (hand) and so on. (2) assist construction project fuck and other technical and engineering quality, safety, and education. (3) to help the staff disclosure of production technology, security technology, and collecting keep written information in a timely manner. (4) with the personnel concerned to carry out the measurement of quality and safety checks, and technical information. (5) according to the data, to the conservation section chiefs will report on the situation. Four job agencies, conservation management to achieve good conservation, achieve a standard, we must establish a sound management system, to ensure smooth progress. Under the unified leadership and management at different levels, to ensure that the concentration of decisionmaking power and unity of mand, and a chain of authority, management at different levels。 Division of labor and cooperation, so that the working groups towards the direction of professional development to ensure corporate goals and conservationComponent objectives of coordination, collaboration on the various functions of the body in action, coordination between the functional departments and managers, the entire management organizations to ensure that capable, efficient, multifunctional. 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)。 fulltime mechanical maintenance group (responsible for watering, cooling, spray during the day), lawn maintenance groups and plant groups. Section with garden plant professional engineer 1, each equipped with the professional technician 1, 2 technicians, carry out their duties. By the Resident Engineer of the conservation section chiefs and marketing grasp work and coordination. After five, lawn maintenance and management of plant construction, often with a 12 lawn maintenance can grow into the fullness of the week. After the lawn grow, but also to carry out regular maintenance and management, to ensure the lawn landscape continues for a long time. Lawn maintenance management including: irrigation, fertilization, pruning, weeding and other links. 1, ir
