Technical and market study of a high temperature heat pump applied to paper machine dryer heat recovery.

Author(s) : LINTON J. W.

Summary

Presentation of a heat pump feasibility study conducted in the pulp and paper industry. The hot vapour laden air in the hood of paper machines is an attractive heat source for heat pumps. In the Canadian case analysed, based on a 500 tonnes per day paper machine, a COP of 5 can be achieved. The pay-back time for a demonstration installation would be two years, including tax and utility incentives. The closed cycle compression heat pump would use HFC-134a, as the operating temperatures would be below 80 deg C.
