Pulp

Pulp dryers have different requirements compared to those for paper machines. Their high basis weights of pulp need special drainage in the wire and press section.

The weight of over 1000 g/m² in combination with the thickness of the pulp has to be dewatered. A special technology for extra dewatering has been developed for the wire section. The use of the SteamTech steamshower adds a high amount of energy by condensing steam into the pulp. The energy is 2690 kJ/kg steam compared to water showers with only a max. of 410 kJ/kg for water. This means there is more than 6-times energy available without adding so much extra water to the process by using steam.

With the special steamshower it is possible to add steam amount of up to 15 t/h. With these mega Watts of energy we are able to increase pulp temperature to temperatures so high that the viscosity of the water is reduced. The technology of the VIB SteamTech steamshower combined with suction boxes creates extra dryness in the wire section.
