一、前言 对于中小型工厂锻件加热的经济性、灵活性、节能减尘、减轻劳动强度等综合条件权衡,首推简易煤气锻炼造炉。但是传统的同类炉型结构,采用中等热值混合烟煤或以低块率的粉状煤屑为燃料时,煤气发生室的燃烧煤层容易板结、结渣、环隙,严重影响其透气性和早期烧穿,造成大量的煤气内 I. Introduction For small and medium-sized factories forgings heating economy, flexibility, energy saving and dust reduction, labor intensity and other comprehensive conditions of trade-offs, devaluation simple gas exercise furnace. However, the traditional structure of the same type of furnace, the use of medium-value heat mixed bituminous coal or coal powder with low briquette rate as a fuel, the gas chamber combustion coal seam easily formed, slagging, annulus, seriously affecting its permeability and early Burn through, causing a lot of gas inside
