One of our neighbors here in Syracuse, an asphalt producer, contacted Griffin
Environmental with a problem. The asphalt plant was a Barber Green built in
1971, in operation for 4 years in New Jersey then moved to Syracuse in 1975. It
was undersized and could not produce at the capacity needed in a reasonable
time. Trucks waited up to 2½ hours for each new batch of product. The problem
was particularly urgent since the business had grown substantially.
Griffin application engineers determined that the current system could be
retrofitted with a JA-462-CE. They were able to use the existing hopper, support
legs and ductwork. The number and length of bags were increased to bring the air
flow from 28,000 ACFM to 37,000 ACFM. A pulse jet cleaning method replaced the
plenum pulse. In upgrading the production line, the owner also installed new
screens.
The new system went on line in June 1990 and it was soon evident
that the upgrade was well worth the effort and expense. Since starting up with
the new baghouse, the customer realized a 33% increase in production which
allowed him to accomplish in 8 hours what had taken 10 hours! Other
advantages:
- Since there are no moving parts, there is less
maintenance.
- Less compressed air is used for the cleaning
cycle.
- The smaller blower (from 125hp to 100hp) uses less
electricity.
- Increased efficiency means less fuel to heat the
product.
After 10 years in operation, the system is still
running at peak performance. There are many small, independent asphalt plants
that could benefit from a similar retrofit and Griffin engineers welcome the
challenge. |
The
Griffin JA-462-CE Jet-Aire is a top load, pulse jet collector operating at
37,000 acfm @ 300º F with an air-to-cloth ratio of 5.2/1. With Griffin's help
in providing a properly designed system, this asphalt contractor realized a 33%
increase in production, smaller electric bills and less
maintenance.
