一、问题的提出发生炉煤气是热值很低的一种煤气。这种燃料目前在国外很少采用,但在我国工业炉作为能源还占相当大的比重。发生炉煤气热值一般为1200～1400千卡/标米~3,这对于锻造和轧钢加热,要求炉温达到1300℃左右,是很困难的。过去在工厂设计中规定,对模锻连续加热时用这种燃料必须采用富氧煤气或添加高热值燃料(附加燃油等)。但在无此条件的许多工厂中,为了提高炉温和加热速度,只好进行各种方式的不正常的强化操作或延长加热时间,虽然这也能维持生产,
First, the question raised Furnace gas is a low calorific value of a gas. At present, this kind of fuels is rarely used in foreign countries, but in our country, industrial furnaces also account for a large proportion of energy. Producer gas calorific value is generally 1200 ~ 1400 kcal / standard meter ~ 3, which for forging and rolling heating, requiring the furnace temperature reached about 1300 ℃, is very difficult. In the past in the factory design provides for continuous heating die forging this fuel must use oxygen-rich gas or add high calorific value fuel (additional fuel, etc.). However, in many factories that do not have such conditions, in order to increase the temperature of the furnace and the rate of heating, various ways of abnormally intensifying operations or prolonging the heating time are required. Although this can also be maintained,
