• Start of the BL furnace.
• The start of the furnace begins with checking the technical condition of the furnace, the presence of the initial solution, testing all the mechanisms in operation.
• The sequence of operations for starting the furnace:
• - the furnace is sealed;
• - the smoke exhauster is included in the operation and a vacuum is created in the furnace 5-8 mm water column;
• - the supercharger is put into operation according to the instructions;
• - a gas burner is ignited while supplying primary air. Ignition of a gas burner is carried out in accordance with the operating instructions for the furnace of the furnace to "BL".
• - the furnace is heated to a temperature of 600-6500 C;
• - secondary air is supplied to create blast elasticity under the hearth, while the air flow is brought up to 6000-9000 m3 / h;
• - the temperature under the hearth rises to 780-8000 C;
• - a layer is loaded, granular zinc sulfate with a granule size of 3-4 mm in an amount of 2-3 tons is used as a material;
• - air consumption increases until the blast elasticity is established under the hearth 800-900 mm and amounts to 10000-12500 m3 / h;
• -the temperature in the layer rises to 190-2600 C;
• - the pump for supplying the solution to the nozzles starts up.
