【摘要】 对分层均燃煤层特性进行了冷态试验研究，得出分层供煤直观看能得到非常好的分层堆积效果，但煤层空隙率和通风阻力数据并未证实分层供煤煤层具有明显的优势。更多还原

【Abstract】 The cold test on characteristics of uniform coal layer in chain grate boilers were carried out. It was found that very good bulking result can be achieved through tiered coal feed. But this was disadvantageous at porosity of coal layer and ventilating resistance.更多还原
