锅炉4（Boiler 4） 18 determination of the optimum operation mode of boiler 19 what kind of economic performance data can be obtained through boiler combustion regulation test? 22 how to prevent and mitigate boiler corrosion? 24 boiler start-up speed is how to specify, why can not speed up too fast? 28 what is the influence of the burner oscillation on the air field inside the furnace? 61 what are the factors that affect the combustion economy in operation? 77 why is unchanged in the amount of fuel under pressure increased, indicating reduced steam flow meter, and the pressure is reduced, the steam flow meter indication increases? 18 determination of the optimum operation mode of boiler The best operation mode of furnace should be considered in two aspects; 1, the optimum operation mode under different loads. Through load adjustment, reasonable load distribution can be obtained, the excess air coefficient of boiler pulverized coal fineness, one or two times the rate of wind speed, and the burner. When they are applied to the stable load of boiler operation, the more economical operation mode can be obtained. 2 boiler economic load. In 75 ~ 100 load range, the combustion stability in variable combustion adjustment of best value and reasonable operation mode, the load change and the boiler efficiency experiment, obtained the boiler efficiency under different load. Among them, the boiler with the highest efficiency is the economic load. The unit shall operate as close as possible to the economic load. 19 what kind of economic performance data can be obtained through the boiler combustion regulation test? 1) on the most suitable equipment for coal combustion adjustable parameters, such as: the fineness of pulverized coal; 2) fuel and air supply mode is reasonable, under different loads, such as excess air coefficient, one or two wind rate effect on the combustion efficiency of 3) under different load of the heating surface before and after the parameters, including gas and t
