Electrically-heated hood cuts carbon emissions in tissue mills

Anew type of drying hood with electric heating for use in tissue mills has been launched by Andritz .

The hood, which produces no carbon dioxide emissions in the mill, offers better energy efficiency and productivity, and enables tissue machine operators to avoid the use of fossil fuels and to progress towards their sustainability goals.

Andritz says it already has an order for the electric hood with startup expected before the end of 2023.

George Nowakowski, vice president of tissue drying at Andritz Canada, commented: “We developed the new hood in close cooperation with customers. It perfectly matches today’s need for sustainable and especially carbon dioxide reduced high-quality tissue production. Having received the first order right after the market launch is the best proof that we are meeting our customers’ needs.”

The PrimeDry Hood E uses electric elements to heat the air flow. As a result, overall carbon dioxide emissions are cut by about 70 per cent compared with conventional gas-heated systems. Without the need for combustion air, energy efficiency for the drying system is said to improve by up to 4 per cent compared to gas-heating. With its ability to achieve air temperatures of up to 450 deg C, the hood contributes to higher productivity compared to steam-heated systems.

The Hood E is also available as a hybrid model, with an air system that combines electric heating with natural gas burners working in tandem.
