Test burns have been scheduled at three coal-fired power plants.
GDT Tek, Inc., Largo, Fla., a company focused on renewable and sustainable energy technologies, has announced that Green USA Recycling (GUSAR), Westfield, Ind., has scheduled test burns of its refuse-derived fuel (RDF) pellets at three coal-fired power plants across the Midwest.
According to GDT Tek, RDF pellets have proven to be a viable alternative or supplement to coal, with significantly lower sulfur and nitrox emissions, according to GDT. GDT Tek's heat capture technology is also recommended to GUSAR’s power plant customers as a way to increase the kilowatt hour output of every pound of fuel.
Bo Linton, president of GDT Tek, says, “This is a fantastic opportunity for GDT Tek and Green USA to establish our companies as the best environmental and economical landfill systems. GDT Tek’s patented Phoenix waste-heat-to-electricity technology can incorporate efficiently into its process a method to use its excess heat to help produce these RDF Pellets, so it’s a perfect fit for us.”
Don Willis, president of GUSAR, says, "As the energy industry begins to move toward renewable fuels such as RDF pellets, gaining efficiencies in the fuel-to-energy conversion process becomes more important than ever. The ultimate goal is 100 percent conversion of fuel to energy. Coal fired boilers from the 1950s may be as low as 30 percent efficient in their ability to convert that heat to energy. With modern boilers surpassing 50 percent, we still have a long way to go. The remainder is waste heat.”
Willis adds, “Until the day arrives that we can convert 100 percent [of fuel] to usable energy it is imperative that we capture as much of that waste heat as possible and convert it to usable energy. Our relationship with GDT Tek allows us the opportunity to add that capability to our portfolio as we speak with our power plant customers."
