Extensive experience at Granite Power

The Granite Power team have worked in the energy industry for several decades and throughout this time have engaged in landmark projects with iconic global and Australian companies such as Babcock, ALSTOM and AE&E. The experience they gained from these and other projects has today been invested into development of our low cost zero emission waste heat to energy technology, providing energy solutions across the world, and research into future innovation. Some of these projects included 3 metallurgical furnaces providing 12.5 MWe of electricity to the BHP Temco Bell Bay site in Tasmania, a gas/oil fired boiler for a 60 MWe steam turbine plant at Alcoa’s Wagerup site in Western Australia and waste gas thermal oxidisers, heat recovery boiler plants, a standby thermal oxidiser and independently died super heater for the TiWest Kwinana site also in WA. ALSTOM projects featured a 76 MWe power plant utilising steam turbines and gas fired boilers for Murrin Murrin Nickel, a HRSG producing steam for an 80 MWe turbine at the Cockburn 1 plant and for Bluescope Steel Port Kembla a blast furnace gas (BFG) and economiser. AE&E projects for Western Australian sites Ravensthorpe Nickel, Sino Iron (CITIC Pacific) and Worsley Alumina included gas-oil fired boilers for 18 MWe turbines, 150 MWe CCGT blocks and 57 MWe circulating fluid bed...

Widespread interest in Granex® energy solution

Industries as varied as a sugar mill, cement kiln and iron ore mine have requested that Granite Power conduct feasibility studies demonstrating the benefits of our exclusive GRANEX® waste heat to power (WHP) technology. To date these projects have included attaching GRANEX®to a sugar mill boiler flue (~600 KWe net plant), process boilers (~200 KWe net plant), mine site generator sets  (~1000 KWe net plant), bauxite mine gen sets (~1040 KWe net plant), sewage gas gen set (~300 KWe net plant), copper mine gen sets (~850 KWe net plant), oil shale refinery (8 x GRANEX®units from 1 – 3 MWe), a silicon smelter (~3.0 MWe + 1.5 MWe net plants), chemical plant (~600 KWe net plant), zirconia furnace (~580 KWe net plant), cement kiln (~5.4 MWe net plant), iron ore mine gen sets (1.5 MWe net plant), steel mill smelters (1.5 MWe net plant), steel mill furnaces (~350 KWe net plant), a landfill gas gen set  (~250 KWe net plant) and landfill gas flare exhaust (~850 KWe net...

Granex supplying east coast grid

AUSGRID approved the connection of our GRANEX®solar thermal demonstration unit to the East Coast grid in late 2013. It features hybrid waste and solar heat generation – the solar thermal heat coming from an adjacent solar array. The ~35 kWe unit – installed at Wallsend in Newcastle – includes waste heat simulation (powered by a gas burner) to show waste heat being recycled as electricity.  Thermal storage ensures a constant energy flow during day time intermittencies (cloud) and evening periods. At its core is a G30 turbo-generator which operates at pressure of about 60 bar with waste heat moving at more than Mach 1.7 through the front nozzle and spinning the turbine blades at 70,000RPM. GRANEX®-generated electricity costs significantly less than that of genset power and it has zero emissions thus adding to the supply of ‘green’power in the grid. The unit also provides thermal heating for a neighbouring Olympic size swimming pool.
