我厂 KD——1型锅炉是美国一九○六年出厂的机车车头改装的,按资料记载,其额定蒸发量应在5——6吨。但自一九七五年夏季投入运用以来,始终达不到这一标准。在夏季高温季节,最好的司炉工操作,只能达到3.3吨。所以几年来我厂生产中最大的矛盾就是蒸汽量不足、汽压低,其直接后果是糠醛生产得率太低。以七七年为例,平均要33吨玉米芯才 Our factory KD - 1 boilers are modified locomotives manufactured in the United States in 1906. According to the information, the rated evaporation should be 5 - 6 tons. However, it has not reached the standard since its introduction in the summer of 1975. In summer hot season, the best stoveman operation, can only reach 3.3 tons. Therefore, the biggest contradiction in the production of our plant over the past few years is the lack of steam, low vapor pressure, the direct result of furfural production is too low. Take seven or seven years as an example, an average of 33 tons of corn cob was
