摘要：In spite of recent moves to wean the world of fossil fuels,coal remains the main source of power in many countries.Coal yards are prone to spontaneous ignition,a problem faced in every country that stores or transports coal.Depending on the environment-temperature,ventilation,and the rank of the coal-heating and self-ignition can be a longer or shorter process,but the possibility can never be entirely dismissed.A plethora of studies have modelled this oxidation behavior and pro-posed countermeasures.Most often,human intervention is necessary,which is both slow and dangerous for the firefighters involved.In this study,we propose to build a complete firefighting solution which is mounted on a number of towers sufficient to cover the area of an open coal yard,complete with redundancy.Each tower includes an inexpensive infrared detector,a water dispenser and a controller programmed to identify areas of elevated temperature,and actuate the dispenser.The heat direction algorithm calculates the parameters to position the water dispenser so that it covers the area.A prototype has been built from inexpensive components to demonstrate the effectiveness at detecting and extinguishing arising fires,and a solu-tion has been costed for the coal yard in the case study.This work has been conducted in collaboration with the managers of the coal yard of a power plant.
