摘要

本文提出了一种计算天然固体燃料致密层空气阻力的方法,以便在考虑各高度层与锅炉机组废气从液体到蒸汽的水分相变化和干燥过程持续时间的情况下预测干燥装置尺寸。提出了一种考虑气流阻力的算法,计算了在气流速度变化的情况下,通风移动致密煤层中物料和气体的温度变化规律。

MATHEMATICAL MODELING OF DRYING DENSE COAL LAYER VENTILATED BY BOILER UNITS’ EXHAUST GASES
The article proposes a method for calculating air resistance of a dense layer of natural solid fuel in order to forecast the drying installation size while taking into account the moisture phase change from liquid to steam and duration of drying process of various height layers with boiler unit’s exhaust gases. An algorithm is presented and temperature patterns of material and gas in ventilated moving dense coal layer is calculated considering air resistance of a dense layer when velocity of gas passing through the layers changes.
