Coal Technology in the Philippines

The 164-megawatt coal-fired power plant at Barangay Ingore, La Paz here that was inaugurated recently by President Benigno C. Aquino III uses clean coal technology that its owner, Panay Energy Development Corporation (PEDC) said was conceived to be environment-friendly.

PEDC chair Francisco Sebastian said the company opted to use clean coal technology as this was well-suited and compliant with environmental requirements and standards.

Clean coal describes technologies being developed that aim to reduce the environmental impact of coal energy generation. It usually addresses atmospheric problems resulting from burning coal.

Sebastian said the plant utilizes the latest circulating fluidized bed (CFB) boiler technology which ensures practically negligible levels of emissions – a 95 percent and higher efficiency in removing sulfur dioxide and practically zero nitrogen oxide – and capture of total solid particles at 99.9 percent.

CFB is a comparatively new technology that has given boiler and power plant operators greater flexibility in burning a wide range of fuels. It is distinct from pulverized coal boiler technology which was in use for nearly a century before advances in firing coal technology gave birth to a much cleaner CFB technology.

Low emissions are a key benefit of the CFB technology, allowing PEDC to meet the strictest environmental standards and operate at low combustion temperatures while giving the fuel long burning times, resulting in naturally low nitrogen oxide (NOx) formation and high combustion efficiency.
