Biomass-to-Energy CHP Stations

CHP Bio-Energy Power Stations

A CHP Bio-Energy Power Station is described as a Waste-to-Energy (W2E), Combined Heat and Power energy generating facility. It produces both the heat and electricity in varying combinations, which can be tailored to produce desired amounts of either. The main structure houses a variable number of modules operating in a parallel array, each delivering 12MW’s of electrical power and approximately 5MW’s equivalent (15Mbtu) of process and sacrificial heat.

Each station consists of a traditional two-stage thermal reactor which utilizes proven proprietary pulse-jet technology and “off the shelf” boilers and turbines. The stations are built in 12MW modules (or “Pods”) for simplicity in expansion and redundancy. This compact and scalable design provides flexibility for various sized projects.

ecoTECH’s waste-to-energy power stations combine technologies to effectively process and convert biomass and other feedstocks, under environmentally friendly conditions, into electricity. ecoTECH’s proprietary design uses multiple fuel stocks and produces higher mass-to-energy with almost zero harmful emissions to the environment.

For a typical 36MW Power Station: approximately 460 tons of biomass feedstock would be processed each day (during one eight hour shift) for 260 days per year, yielding 130,000 tons of fuel annually – enough electricity to provide 36 megawatts per hour, 24 hours per day, for 365 days per year (approximately 315 gigawatts per year). This is enough electricity to power 40,000 homes at average North American consumption rates.

Delivery of Heat from CHP Stations

A 36MW Power Station produces raw heat energy in the magnitude of 165 GigaJoules (156 Mbtu) per hour, running 24 hours per day for 365 days per year. This equates to 17 MWe (17 megaWatts electricity equivalent) per ecoPHASER x 3, radiated into the boilers, superheaters, reheaters and economizers – thus converting energy into steam which turns the multiple stages of turbo-fans that comprise the steam turbines, which produces mechanical energy to revolve generators to electro-magnetically generate electricity, resulting in heat and mechanical losses that are circa 15 Mbtu (roughly 16 GigaJoules) of energy, most of which is available as high heat energy for use or transportation to a consumer.

The heat is transported via a piped Thermax® oil medium, that does not boil until over 700oF (371oC), hence no pressure of expansion as in steam systems; so no leakage, corrosion or burst potential. The insulated transmission pipes are small bore <55mm (2.2”), pumped at high speed around the circuit, usually 5 feet (1.5m) below ground and very safe. Heat is pumped to take-off points (heat exchangers/radiators) that may be housed in boilers for steam or hot water heaters.
