Objective
To modify an existing furnace for experiments on replacement of the fuel-oil with blast furnace gas and oxygen enriched combustion air.
This project was stopped because the important expected sale of coke-oven gas to the chemical industry was not realized. The state of advancement of this program at the contract cancellation date was as following :
- the studies on the furnaces modifications were realized.
- the burners were modified to work either with low enriched blast furnace gas and oxygen enriched combustion air to a rate of 40 %, or with rich gas and atmospheric air.
The heavy plate mill is equipped with 2 pusher furnaces :
- A 110 T/H furnace with 3 reheating zones
- A 180 T/H furnace with 5 reheating zones
For this experiment the 110 T/H furnace only will be modified. To allow this furnace to work with low up-graded gas and oxygen enriched combustion air, it is necessary to increase the dimension of the gas feeding pipes, to modify the burners and to build a new oxygen network to feed each burner with oxygen. To protect the waste gas circuit and the recuperator, a new protection system is also foreseen.
