ElectraTherm installed two Power+ Generators at FOSFA, a manufacturer of phosphoric acid and phosphates in the Czech Republic. The manufacturing plant has been in operation since 1884 and maintains a culture of environmental standards geared towards ensuring all waste is processed in the most efficient, environmentally-friendly way.
The manufacturing plant operates four 250kW internal combustion engines for onsite power. ElectraTherm’s Power+ Generators run in parallel with two of the engines, supplied by hot water from the jacket water and exhaust systems of the engines at 88-95°C.
The machines are cooled by a cooling tower the facility already uses for their chemical process. The cold water runs through the Power+ Generators at approximately 16-24°C.
Each of the two utilized IC engines are currently producing between 175-220kWe. The two Power+ Generators each generate close to 26kWe, increasing site efficiency and reducing the plant’s carbon footprint.
Power+ power is fed back onto the grid and meets national feed-in tariff requirements for renewable energy.
“ORC technology complements the Czech Republic’s pursuit towards its national renewable portfolio goals because it utilizes a pre-existing heat source without the investment, environmental-footprint and risk often associated with other renewable technologies,” said Lokchandar Selvaraj, President of GB Consulting, ElectraTherm’s eastern European distributor. “The Power+ is also robust with low maintenance requirements, maximizing the machine’s return on investment.”
