Fly ash handling is an essential process in any coal-fired or biomass power plant due to stringent environmental regulations – not to mention the need to maintain general plant efficiency. Designing an appropriate fly ash handling system can be difficult without experience and qualified engineers. There are several challenges that… Read More
Dealing with ash is one of the main challenges facing a plant or mill manager. Ash has to be removed, but it needs to be removed in a cost-efficient manner – and in a way that doesn’t run afoul of regulations. To save money and streamline operations, managers have to… Read More
Generally speaking, fly ash is the ash that has gone through the boiler furnace and steam generating bank sections. It is collected beneath the equipment in downstream hoppers, such as the air heater, economizer, precipitator, dust collector, baghouse, and so forth. Let’s take a closer look at how fly ash… Read More
No equipment in the fuel handling chain endures as much hardship as the ash handling systems that are set up in facilities around the world. Due to the intense temperatures and abrasive conditions of their environment, many ash handling systems fail to operate properly, which presents a problem for plant… Read More
Over the past eight years – beginning with a coal ash spill in Kingston, TN, in 2008 – there have been numerous incidents involving coal ash that made its way into the environment. Part of the reason is that many facilities have no use for coal ash, so they must… Read More
Two weeks ago, the U.S. House of Representatives approved a bill titled “Improving Coal Combustion Residuals Regulation Act of 2015”, a bill that seeks to change key regulations on coal ash handling put into place by the Environmental Protection Agency. Previously, the EPA set forth several regulations under their proposed… Read More
For years, wet bottom ash handling has been the standard for power plants throughout the world. Systems that use impounded hoppers or submerged scrapper conveyors have traditionally handled ash using water as a primary medium. Now, however, a growing emphasis on environmentally-friendly production has caused many power plants to reconsider… Read More
There are countless biomass boilers in the United States that generate energy from various biomass sources, from softwood and hardwood to forest trimmings, grasses, paper waste, and agricultural byproducts. During the process of creating the growing amounts of energy these plants produce, these facilities also generate a tremendous amount of… Read More
