At Rieco, we are continuously striving to enhance the performance of our Pneumatic Conveying Systems<\/a>. Recently, we embarked on in-depth research to optimize blow tank designs for the reliable dense-phase conveying<\/a> of ash<\/strong>, particularly for economizer hoppers and the 2nd<\/sup> & 3rd<\/sup> fields of the ESP (Electrostatic Precipitator).<\/p>\r\n\r\n\r\n\r\n

Our goal was to ensure efficient and consistent ash feed into the pressure conveying pipeline, which requires blow tanks specifically designed for varying ash characteristics across different collection points.<\/p>\r\n\r\n\r\n\r\n

The Challenge<\/h2>\r\n\r\n\r\n\r\n

Traditional blow tanks were designed for handling ash from ESP (Electrostatic Precipitator)<\/a> first fields, which have high ash collection rates. However, for the finer ash collected in ESP second and third fields, as well as from air preheaters and economizers, standard blow tanks proved unnecessarily large and inefficient. The challenge was to optimize tank size and weight to handle lower ash discharge rates effectively, while ensuring reliable dense-phase conveying with minimal air consumption.<\/p>\r\n\r\n\r\n\r\n

Methodology and Development<\/h2>\r\n\r\n\r\n\r\n

Our multi-phase approach involved several critical steps:<\/p>\r\n\r\n\r\n\r\n
