The article proposes an application mode of using a toothed rope material conveying device for ash conveying,addressing the issues of high energy consumption,environmental risks,and high maintenance costs in current positive pressure dense phase pneumatic ash conveying systems.By comprehensively analyzing the characteristics of poor flowability and high hardness of dry ash,considering the problems of long conveying distance,multiple directional changes,high elevation angle,and vertical conveying,nano ceramic materials were applied in the conveying device,and a combination of toothed chain bucket,scraper,and bucket lifting conveying methods were designed to achieve effective conveying of ash materials;Effective control of negative pressure in dust collectors and air and smoke systems is achieved through self-designed DCS control logic.After system trial operation,significant economic and environmental benefits have been achieved,and it has good prospects for promotion and application in coal-fired power plants and related industries.
