A tuyere head with a solid nozzle block contains concentrically disposed central, intermediate and outer connecting pipes, tracts for gas supply, feeding and withdrawal of cooling water, solid multinozzle block with a central water channel and input and output channels for coolant passing between the nozzles. The area of the passage section of the gap is defined by the ratio. An empirical coefficient is equal to 0.08- case, when feeding channels for the coolant passage between the nozzles are disposed lower than the withdrawal channels and 0.05- case, when the feeding channels for the coolant passage between the nozzles are disposed above the withdrawal channels. |
