求翻译：由于高炉煤气发热值Qlow约为3000～3200 kJ／m3，烧纯高炉煤气时很难得到1250℃的风温。如高炉煤气中混入5％～10％的焦炉煤气或转炉煤气以富化高炉煤气是最为简单和有效的方法.是什么意思？

Blast furnace gas calorific value is about 3000 ~ 3200 kj m3 qlow burn pure blast furnace gas is difficult to 1250 ° C air temperature. Mixed with 5% ~ 10% of the coke oven gas or converter gas-rich blast furnace gas is the most simple and effective methods such as blast furnace gas.

The blast furnace gas heating value Qlow is approximately 3000 ~ 3200 kJ M3 and to burn pure blast furnace gas, it is difficult to get 1250 °C the wind temperature. If blast furnace gas mix in 5 per cent to 10 per cent of the coke oven gas or gas in the rich, aisc blast furnace gas is the most simpl

Due to the blast furnace gas heating value about 3000~3200 kJ m3 Qlow burning plain are hard to come by when the blast furnace gas temperature 1250 ° c wind. Blast furnace gas is mixed in with 5%~10% or converter gas in coke oven gas of blast furnace gas-rich is the most simple and effective way.
