ПЫЛЕПРОВОД

Полезная модель относится к трубам для транспорта пылевидных материалов, применяемых в различных отраслях производства, в нашем случае - на тепловых электростанциях, сжигающих твердое топливо в пылевидном состоянии. Полезная модель использует в трубе плавного поворота в вертикальной плоскости центробежное ускорение, направленное вверх и равное ускорению свободного падения «g» (9,8 м/с2). Это позволяет достичь эффекта «невесомости» потока аэросмеси в нем, уменьшить его сопротивление, исключить сепарацию пыли и появления пульсаций, что особенно важно для пылепроводов транспорта концентрированной пыли в схемах ПВКд.
