为了节約工业的粮食——煤炭,彻底改善鍛造車間的环境卫生,杭州制氧机厂用自力更生的办法,土法开道,制成簡易煤气发生爐,顺利地实現了鍛件加热煤气化。煤气火焰加热炉的結构如附图所示。加热室面积是900×900。用离心式鼓风机,轉速1800～2200轉/分,由7千瓦电动机带动。风压300毫米水柱,风量50米~3/时。爐腔部分用耐火砖砌成,爐子外部砌普通机制紅砖,砖缝用火泥和石英砂粘结紧密,防止漏气。煤气出口管道三只,安装斜度按加热爐大小来决定。
In order to save industrial grain - coal and completely improve the sanitation of the forging workshop, Hangzhou Oxygen Plant uses self-reliance to open the way to make simple coal gasifier and smoothly achieve forging coal gasification. Gas flame furnace structure as shown in the figure. Heating room area is 900 × 900. Centrifugal blower, speed 1800 ~ 2200 rev / min, driven by a 7 kW motor. Wind pressure 300 mm water column, air volume 50 meters ~ 3 / hour. The furnace cavity is made of refractory bricks, and the outside of the furnace is made of ordinary red brick. The bricks are tightly bonded with fire clay and quartz sand to prevent air leakage. Gas outlet pipe three, the installation slope according to the size of the furnace to decide.
