某德制波西克(Borsig)CTM型分联箱链条式锅炉,汽压为32公斤/公分~2,汽温为405℃,正常出力为23吨/时,最大连续出力26.6吨/时。按原设计方式,在炉排两侧及后墙下端各装有水平放置的防焦箱(200× 200× 25 × 5500公厘)。但是,由于后墙下端的防焦箱曾发生过数次爆破故障,因此,在安装后的第三年(1939年)改为外部冷却方式。炉排两侧的防焦箱,其降水管系由汽包下端引出,水流经过防焦箱 A German-made Borsig CTM splitter chain-type boiler, steam pressure of 32 kg / cm ~ 2, the steam temperature of 405 ℃, the normal output of 23 tons / hour, the maximum continuous output of 26.6 tons / hour. According to the original design, both sides of the grate and the rear wall are equipped with horizontal anti-coke box (200 × 200 × 25 × 5500 mm). However, since the defocusing box at the lower end of the back wall had failed several times before demolition, the external cooling method was changed in the third year after installation (1939). Anti-coke boxes on both sides of the grate, the precipitation pipe from the lower end of the drum leads to flow through the anti-coke box
