Environmentally: responsible coal boilers

摘要

After carefully considering the fluctuations of the natural-gas market in recent years, PT Pupuk Kalimantan Timur (Pupuk-Kaltim), Indonesia's largest fertiliser producer, in Bontang, East Kalimantan, launched a project to diversify its fuel with a coal boiler in 2009. In addition to adhering to government policies that encourage the use of coal as a substitute for natural gas, Pupuk-Kaltim executives noted substantial economic benefits. One possible problem was the environmental impact. Addressing that, Pupuk-Kaltim chose to use only clean-coal technologies, including a circulating fluidised bed boiler, a Geometrica coal-storage dome and a continuous barge unloader. These technologies had earned recognition for their successful use at the JEA Northside power plant in Jacksonville, Florida, and help keep the environment around the facility pristine.
