Abstract

一种自预热煤气点火保温炉,点火炉3的炉顶5为平顶,其上装有两排烧嘴1。在点火炉3后端设有换热器2,所述换热器为本领域常规技术装备。换热器2的集风管,通过风管6,分别连通各烧嘴1的空气入口。本实用新型结构紧凑,设置换热器,利用烧结矿辐射热加热空气,不需要外加热源,提高了热效率和烧结矿产量,节约燃料。

Description

自预热煤气点火保温炉
                      技术领域
本实用新型涉及一种用于将粉状物料烧结成块状物料的点火保温炉。
                      背景技术
现有煤气点火保温炉,它的保温段只起保温作用,没有设置利用烧结矿辐射热加热空气的换热器,致使保温段的热量没有充分利用。为提高点火炉内温度,有的需另设外加热炉,将送入烧嘴的空气和煤气混合气进行预加热,这样明显多耗能源,增置设备,加大了成本。
                      发明内容
本实用新型的任务,是要提供一种能有效利用热能的自预热煤气点火保温炉。
本实用新型的技术方案是:在点火炉后保温段设置有换热器,换热器集风管的热风出口,用风管连通烧嘴的空气入口,使助燃空气通过换热器加热后进入烧嘴。
本实用新型结构紧凑,设置换热器,利用烧结矿辐射热加热空气,不需要外加热源,提高了热效率和烧结矿产量,节约燃料。
                      附图说明
图1为实用新型装配示意图。
图中1、烧嘴,2、换热器,3、点火炉,4、台车,5、炉顶,6、风管。
                      具体实施方式
下面结合附图介绍本实用新型。
参照附图,装有矿料的台车4,通过点火炉3,将粉状物料烧结成块状物料。点火炉3的炉顶5为平顶,其上装有两排烧嘴1。点火炉3后端设有换热器2,所述换热器为本领域常规技术装备。换热器2的集风管,通过风管6,分别连通各烧嘴1的空气入口。
