help mitigate risks of fire and explosion in electric generating plants by complying with the latest recommended safety practices. there are special concerns for fire and life safety in plants and facilities that produce or convert the current of electricity. the nfpa 850, 2020 edition, provides access to cutting-edge criteria for fire prevention and protection of plants generating electricity. developed to provide a document specifying fire protection measures for all types of non-nuclear electric generating plants, the revised nfpa 850 reflects the most current industry knowledge and best practices.
nfpa® 850 recommended practice for fire protection for electric generating plants and high voltage direct current converter stations, 2020 edition nfpa 850, recommended practice for fire protection for electric generating plants and high voltage direct current converter stations outlines fire safety recommendations for gas, oil, coal, and alternative fuel electric generating plants including high voltage direct current converter stations and combustion turbine units used for electric generation. (print, 82 pp., 2015) effective with the annual 2020 code cycle, nfpa® will no longer offer access to the pdf format as a choice for new editions of codes and standards, handbooks, or other reference titles. for more information about the different format options available to access essential code and standard content you need, click here. please see applicable nfpa codes and standards product pages to confirm which editions are available for purchase.
we have written about nfpa 850 several times in its connection to gas-fired power plants, coal-fired power plants, and bio-diesel plants. gas-fired power plants are growing in popularity. however, with a surge in gas-fired power plants being built, a closer look needs to be taken on the fire hazards within these plants. in 2010, the kleen energy systems power station, a combined cycle gas and oil power plant, had an explosion in the turbine building when natural gas was being purged from the gas line. in 2014, the didcot b power station, a gas-fired plant, had a major cooling tower fire. however, it does serve as an example of what can happen in gas-fired power plants and the need for proper fire protection. fire hazards are abundant in gas-fired power plants. gas-fired power is on its way to becoming one of the biggest producers of power in north america.
but what are the fire hazards in these plants? the lower nox and so2 in prb coal reduced power plant emissions, decreasing pollution, and appeasing the 1990 clean air act. at the same time, the low cost and availability made prb coal not only a viable option, but a fuel of choice. with the current government crack-down on coal-fired power plants, the existing plants will likely be the last. after all, there is a reason the industry saying is, “it isn’t if a fire occurs, but when.” with the prospect of aging coal-fired power plants and their propensity for combustion, it is essential to understand their fire hazards and insure the fire protection preparedness of coal-fired power plants with extensive fire protection solutions. there are several options for fueling plants: solar, biofuel, combined-cycle – but the fuel of the moment is natural gas. however, the process of converting fuels can be hazardous. there are numerous fire protection considerations that need to be made before, during, and after the conversion.
this recommended practice outlines fire safety recommendations for gas, oil, coal, and alternative fuel electric generating plants, including high voltage nfpa 850 requires the development of a fire protection design basis document that identifies relevant hazards — such as the presence of fuels, lubricating oils nfpa 850 recommendation the annex a of nfpa recommendation 850, defines the 4 criteria for fast depressurization systems. these criteria are highlighted below, nfpa 850 2020 pdf, nfpa 850 2020 pdf, nfpa 850 ppt, nfpa 850 2019, nfpa 805.
because of the loopholes in regulations and the growing number of transformer explosions and fires in 2010, the national fire protection association has nfpa 850 is the fire protection recommendations for electric generating plants and high voltage direct current converter stations. nfpa 850 provides recommendations for fire protection for power plants that are- fossil fueled (coal, gas or oil) or alternative fueled (e.g biomass etc), nfpa 850 scribd, nfpa 13, nfpa 70, nfpa 855.
