The procedure for stopping the furnace:
The procedure for stopping the furnace:
- the flow of solution to the nozzles and gas to the burner stops;
- nozzles are taken out of the furnace;
- air supply to the furnace continues until the layer is completely unloaded through the threshold;
- the supercharger and the exhaust fan turn off.
Technological computation.
Colculation of zinc smelting equipment to obtain zinc sulphate.
Melting of zinc in the equipment is carried out in the following equation.
Melting of zinc in the equipment is carried out in the following equation ∑.
Zn+0.5O2+H2SO4→ ZnSO4·5H2O

Ecology and labor protection.
The rapid development of electronic technology in the human world has led to great changes in human life.There was food, clothing, home heating, a variety of vehicles, a change in the environment.The release of carbon monoxide, sulfur oxides, nitrogen oxides, fluorine industrial dust and moisture into the atmosphere from the development of especially heavy industry - mining, metallurgy, chemical light industry - causes environmental problems.For example, 70% of atmospheric transport, 250 million tons of dust, 200 million tons of carbon monoxide, 150 million tons of sulfur oxides per year. Annually, 25% of industrial waste is iron, 80-90% of mercury and lead.
metal compounds are absorbed by plants and pose a threat to living organisms. Including the effects of the noise around us on the human body causes 85-90 getsbl high neurological diseases. Gaseous, liquid and solid phase wastes from the chemical industry should be neutralized.
