| Abstract: | In order to increase the blast temperature up to 1250℃,a series of measures have been carried out,such as adopting the hot blast stove with whirling top combustion,using pre- heating furnace and heat exchangers to preheat combustion air and gas,and using the technology of porous furnace grate with beam,pipe insulation and optimized combustion. By controlling the appropriate bosh gas index,theoretical combustion temperature,gas flow distribution and standardizing operation,the annual average blast temperature achieve 1248℃ in 2013,which is of advanced level for the same type of blast furnace. |
