五、煤气炉的构造炉子的构造和设计,对煤气制造影响来说,是一个静的因素。也就是说,煤气炉的设计和建造一旦完成后,就不可能随使更改变动。因而,对炉的设计和结构或采用那一类型的炉子,都须依据各厂实际情况审慎确定。譬如说:用于甲厂有优良成绩的炉子,若 Five, the structure of the furnace Furnace structure and design, the impact on gas production, is a static factor. In other words, once the design and construction of gas stoves have been completed, it will not be possible to make changes with the changes. Therefore, the design and construction of the furnace or the type of furnace used must be carefully determined on the basis of the actual conditions of the plants. For example: for a factory with excellent results of the stove, if
