POLLUTION CONTROL:
The production of steel, whether a blast furnace or electric furnace is used, results in the pollution of huge volumes of air which must be collected and purified. The in-depth knowledge of the cast iron and steel working processes enables Boldrocchi Ecologia to make accurate forecasts about the volumes and temperatures of the smoke with a view to identify the most suitable design for the cleaning system. The extraction of gases at extremely high temperatures requires water-cooled tubular walled ducts, while the elimination of the heat from the smoke requires tube nest or evaporating exchangers. Boldrocchi Ecologia has a great deal of experience in the construction of these devices which it designs within the company to ensure maximum reliability. Smoke purification is carried out by bag filters capable of reducing emissions to a concentration of a few milligrams; sometimes large electrostatic precipitators are preferable due to their remarkable resistance to wear over time. Boldrocchi fans ensure that the extraction plants operate continuously and reliably with a maximum energy saving.

The dust is collected, transported and accumulated by means of mechanical or pneumatic systems, always hermetically sealed to prevent the risk of pollution of the environment. The full automation of the plants is based on the use of advanced PLC’s and is designed and implemented by our specialists according to the Customers’ requirements.
