Power Plant Technology

Conditioning of Ash and Dust

No matter where ash and dust accumulate, AVA continuous or batch mixers can condition them to a transportable final product for disposal or recycling. The applications range from power plant ash derived from lignite, hard coal, biomass, or waste incineration power plants to filter dusts from steelworks and coking plants through to special applications such as hot or reactive ashes from various processes, such as shale oil production.

The dust humidification methods are highly refined, and AVA machine technology has proven itself countless times over many years of practical application.

However, in addition to these, new tasks faced by plant operators and disposers continue to present themselves. For example, changing coal or fuel qualities affect the ash composition, and changed legal limits/baselines make it necessary to find new ways to dispose of/recycle these materials. Therefore, once again AVA focuses on individual and customized mixer and mixing systems design and construction to best serve the changing needs of our customers in this industry.

Deciding Facts – Power Plant Technology

  • Comprehensive product range from individual machines to complete turnkey plants including materials handling, ash and water dosage, vapor handling, controlling, and more
  • No mixer clogging or caking, even after long operating times
  • Very high product homogeneity, short mixing times and thus very high throughputs (up to 1000 t/h) possible due to intensive mixing
  • Very robust mixer design; low-wear parts reduce maintenance costs
  • Low energy consumption

AVA mixers and plants for ash and dust conditioning and humidification are worlds apart from the conventional offering thanks to high reliability and availability, thus ensuring maximum efficiency and low operating costs.
