Objective
To recover the waste heat available from a coal power plant to warm a greenhouse by treating it in such a way that it becomes possible to collect the thermal energy contained in the hot ashes gathered in the boiler combustion chambers.
Forecasted annual energy saving is +- 1500 TOE.
Waste water of the two electric generating sets of 120 and 300 MW in the Ensdorf coal power plant is to be used for the project.
Low temperature waste water flow rate is 460 m3/h and the greenhouse, warmed by recovered heat, is located 3 Km from the plant. This is comprised of three systems, for, as follows:
- energy recovery
- delivery to and from the greenhouse
- thermal devices for heating and temperature control
The energy recovery system involves the mixing of water and ash into 4 mm dia. granules; a basin to catch discharged water; a circulating pump to forward water to a heat exchanger, and a flow rate and temperature control system.
Water is conveyed to and from the greenhouse via a 300 mm dia. pipe.
The 25000 m2 greenhouse surface area is served by a pipe system and by a heat integrating system formed by an independent closed circuit. This is fed by an additional boiler, circulation pump and circuit. Service water is fed at
60 deg. C and the temperature difference between greenhouse and exterior is fixed at 30 deg. C for design purposes.

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
