Research on Energy-saving and Efficiency-improving Transformation of Pilot-type Positive-pressure Dense-phase Pneumatic Ash Transportation
In view of the frequent ash blocking phenomenon in the electric dust removal and ash transportation system of No.1 furnace of a power plant,and the problems such as high velocity of ash transportation system,large pipeline wear,frequent ash leakage and leakage,large gas consumption and energy consumption,pipeline wear and ash running,etc.,pilot-type embolization technology is used to carry out the overall technical transformation of the No.1 power plant,adding pilot-type embolization valve and main structural design of gas tracing pipeline.Through the collection and analysis of technical parameters in the production process,it is found that:in terms of gas-saving,the gas consumption per minute of the No.1 power plant in the full load state is saved by 80 m3,and the gas consumption per minute in the conventional load state is saved by 45 m3;in terms of energy-saving,the average annual electricity consumption under the full load conditions is reduced by 2.44 million kWh,equivalent to 798400 yuan in cash,meanwhile,under the conventional load conditions,the average annual electricity consumption decreased by 1.952 million kWh,equivalent to 638400 yuan in cash.Using pilot-type embolization technology to transform the pneumatic ash transportation of the power plant can greatly reduce the production cost and has positive practical significance for the production of power plant.
