Around 4,000 people attended the 24th Annual Fuel Ethanol Workshop and Expo (FEW) in Nashville, Tennessee, making it the world’s largest Ethanol Conference. The three day event was an exciting opportunity to gather information, meet new and existing business contacts, and get the scoop on trends and opportunities in this fast-growing market segment.

Weis Environmental was there to showcase its Electrostatic Precipitator (ESP), a cutting edge technology product especially designed to reduce emissions in processes of biomass combustion and gasification. And the show turned out to be a great success for the company!

Customers and interested parties representing key U.S. markets flocked to the impressive Weis Environmental exhibition booth, approaching our representatives with specific inquiries concerning the ESP and expressing strong interest in the product. Weis Environmental was the only attending provider for flue gas filtration behind biomass boilers, and it was obvious from customers’ reactions and brand awareness that the company has made a name for itself in this market segment.

The next U.S. event with a Weis Environmental presence will be the EBW Expo in Pittsburgh, October 14-16, 2008.

Electrostatic precipitators (ESPs) have proven their immense value to the timber industry as dedusting systems for both wood-fuelled boiler plants and drying plants. Equally excellent is their performance with other types of biomass combustion (dry ESPs) or biomass gasification (wet ESPs).

BETH® electrostatic precipitators effortlessly lower dust contents well below the legal emission limits of 20 mg/m³ in standard conditions. Compared to conventional filter systems, they offer considerable advantages because of their low energy demands, high operational reliability, low maintenance requirements, and – last but not least – low investment costs.

The electrostatic precipitator can operate either with or without an upstream cyclone (centrifugal) separator. It can reduce raw dust contents of up to 10g/ m³ to clean gas contents of 20mg/ m³ in standard conditions. This corresponds to a separation rate of more than 99%.

Special features of the standard ESP

Our standardized model sizes can purify gas volumes ranging from about 500 Bm³/h (Mini ESP) to 500,000 Bm³/h (Industrial ESP). Each field can be adjusted both electronically and/or separately by mechanic means, resulting in an optimal purifying effect at the lowest possible energy consumption. Robust construction, glitch-free functionality and convenient maintenance options ensure the long operational life of BETH electrostatic precipitators.

More than 120 Years of Success!

Years of continuous operation in the timber industry and other sectors have proven the excellent quality of BETH technology time and again. Moreover, the measuring results speak for themselves: in normal conditions they will always stay below 20 mg/m³, but it’s not unusual to even achieve continuous levels of far below 10 mg/m³.

The usual components of industrial ESPs like emission and precipitation electrodes are also used in the standardized ESPs in the timber industry and in biomass combustion.

Turnkey service for plant systems

For the completion or assembly of turnkey plants we can supply all connecting conduits, ventilators, sound insulation equipment, dust discharge and dust collection components, thermal insulation and electrical equipment. By your request, BETH will also install and start up your plant for you.

The 19th PowerGen International (the world's largest power generation trade fair) took place from December 11-13 at the Ernest L. Morial Convention Center in New Orleans, LA. It was a huge success from day one, with near-capacity attendance throughout the event.

More than forty interested visitors flocked to the booth of WEIS ENVIRONMENTAL LLC on the first exhibition day, drawn mainly by the BETH Electrostatic Precipitator (ESP) on display and the booth's glamorous design that set the company apart from the other exhibitors.

A fantastic outcome for the first day of an exhibition that WEIS ENVIRONMENTAL LLC attended for the first time. Business cards went like hot cakes, and towards the end of the event 90% of the copiously printed info material had been distributed or taken away - and three members of the booth staff were quite hoarse from all the explaining, presenting and chatting with visitors.

After three wildly successful days the WEIS ENVIRONMENTAL LLC booth was dismantled Thursday evening and Friday and was then shipped back to Memphis, which concluded our PowerGen 2007 adventure.

AEROB-BETH responded by offering a horizontal dry electrostatic precipitator and was promptly met with success: the contract was awarded to WEIS ENVIRONMENTAL, the company distributing BETH products in the USA, South America and Canada, in August of 2006.

The successful start-up of the horizontal dry electrostatic precipitator took place this June.

Already, the first test readings show that the filter is meeting the high expectations effortlessly.

BETHPULS horizontal filters are available with regular dust collection hoppers and also in a bin-mounted version.

BETHPULS filter type series BP 45 to 180 H.10 operates with horizontally installed filter elements. BETHPULS horizontal filters are available with regular dust collection hoppers and also in a bin- mounted version.

The horizontal installation and operation of the filter elements makes this BETHPULS series the perfect choice for locations with limited headroom.

4 designs with filter surfaces ranging from 32 m² to 128 m² (344 to 1,380 sf) are available.

The dust is collected at the outer surface of the filter elements, which are cleaned continuously and automatically by jet pipe injectors. This way, the filtration process can go on without interruptions.

Compressed air pulses of 0.1-0.2 seconds are injected sequentially and periodically by jet pipe injectors via jet manifolds, sweeping along secondary air from the clean gas room into the filter elements.

This inversion of the filtration direction causes the filter medium to change its shape, thus flushing and cleaning the filter elements. The collected dust is dislodged from the filter surface and falls directly into the hopper for easy removal.
