Particulate Matter Emission Control & Air Dedusting Hurricane & ReCyclone® Systems

Advanced Cyclone Systems (ACS) Towards total particle capture with optimized cyclone systems ACS is a company exclusively dedicated to the development and supply of the most efficient cyclone systems worldwide. ACS Focus We focus on particulate matter (PM) emission control (EC) in boilers, furnaces and dryers. We also work on enhancing powder recovery (PR) in pharmaceutical, food and chemical processes. ACS Mission Achieving particle capture exclusively with cyclones by continuously researching and innovating, freeing the client from the costs and problems of Electrostatic Precipitators...

Particulate Matter Emission Control & Air Dedusting A problem common to many industries Application Fields Biomass and Coal Combustion Biomass Dryers Pyrolisis, Incineration and Gasification Particulate matter (PM) emission control is a common problem in industries that operate boilers or incinerators for energy production, or furnaces, kilns and dryers for the manufacturing of products, such as ceramics, cement or pellets. High Temperature Separation Processes for Energy Recovery Clinker Cooler and Pre Heater Dedusting Calcination Processes Complying with stack emission limits, avoiding...

About Hurricane Cyclones ACS numerically optimized cyclones How can cyclones be improved? Since the early 1900’s, cyclones have been mostly designed and improved by empirical means, due to the difficulty of building a good prediction method that handles with the modeling complexity related with multiphase and highly turbulent flows. Computerized Flow Dynamics (CFD) can be used for partial cyclone optimization but it is still incomplete for full cyclone optimization, due to the very large computational burden associated with highly vorticial, assimetrical and multiphase flows with...

Alternative Cyclone Solutions A Real Case Analysis: Biomass Industrial Boiler Dedusting Designing a cyclone solution for PM reduction: Depending on the requirements of the client ACS may design solutions that go from a compact pre-separator for sparks and silica reduction (protection of downstream equipment) to a final stage dust collector. The more efficient the solution is, the larger the number of cyclones needed to increase residence time and promote particle agglomeration with impact of space and cost. ACS will always search for the most cost efficient solution. Please compare the...

ReCyclone Systems® Mechanical and Electrostatic Recirculation ReCyclone® (MH and EH) A ReCyclone is made up of a high efficiency Hurricane and a particle separator, placed downstream, called the “recirculator” (please see figure) and which can be purely mechanical or electrostatic. Since the recirculation system only serves the purpose of dust separation (and not collection), the particles are exclusively collected in the cyclones and the need of rapping mechanisms is avoided. ReCyclone systems are arranged in groups of cyclones and recirculators. The main purpose of the recirculators is to...

Technology Comparison Hurricane® Cyclones | ReCyclone® MH | ReCyclone® EH | Other Technologies Approach to any new project Whenever it is possible to achieve a requested emission limit or efficiency with a given optimized cyclone geometry, ACS will avoid recirculation, in order to reduce investment and operating costs (mainly power consumption of fans). In case emission limits become stricter, in the future, any hurricane family can be coupled with mechanical or electrostatic recirculation to increase efficiency. This staged investment is much easier to support than a one shot expenditure...

Case Studies for Biomass Industrial Boilers ACS has supplied hundreds of high efficiency cyclone systems worldwide to comply with strict particulate matter (PM) emission limits in industrial biomass boilers. High Efficiency Cyclones Typically, the cyclones are placed after the boiler’s pre-separator (Multicyclone) instead of a Bag Filter or an ESP. Depending on the case, they can also operate without any preseparator upstream. The system is supplied in pre-assembled modules of cyclones to be very easily Biomass boiler Hurricane RX system for a moving grate 60t 67bar ICAVI boiler burning...

Case Studies in the Wood Panel Board & Pellet making industries ACS technology has multiple benefits whenever there are biomass furnaces and dryers. That is especially the case in the wood panel and pellet making industries. ACS cyclones can be optimized to serve as compact 1st stage separators before ESPs or Bag Filers in large combustion plants or before dryers in order to reduce silica and sparks content or unburnt content in the dried wood chips or shavings, thereby improving product quality. Additionally, numerically optimized cyclones can serve as end stage dedusters both after...

Case Studies High Temperature Processes (Combustion, Incineration, Gasification, Pyrolysis) ACS has been involved in multiple waste-to-energy projects where cyclones can separate particles at very high temperatures (up to 1000°C). Fuel can include various types of biomass, from forestry biomass to animal waste and from Municipal Solid Waste (MSW) to Refuse Derived Fuel (RDF). The use of customized cyclones unfolds in several advantages which includes protecting downstream equipment, reducing operating costs and enabling energy recovery and carbon capture in the form of biochar after fast...

Case Studies in the Steel, Cement and Oil & Gas Industries Thermal energy can also be recovered in large gas streams in the Steel & Cement industries after properly cleaned from dust originated in the cement preheater, in the clinker cooler or in sintering processes. ACS can offer large heavy-duty cyclones with an internal ceramic-based lining to resist abrasive dusts. Cyclones can also be built to handle high pressures very effectively. In the Oil & Gas Industry, that includes the separation of iron oxide powders before critical components such as compressors. Hurricane HR cyclones to...
