Overcoming Challenges with Fly Ash Handling

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

The Logistics of Fly Ash Removal Systems

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

Finding New Uses for Coal Ash

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

Power Plants Shifting to Dry Bottom Ash Handling

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

Explaining Ash Handling Systems for Biomass to Energy Boilers

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
