Baghouse
|
HR-C Baghouse systems are part of a tradition of excellence. Our systems combine more that 40 years of experience in fabric filtration including both HR-C and it's GEESI/Marsulex filter technologies. Our engineers have designed and constructed baghouses for a variety of applications, including coal fired utilities, stoker fired boilers, fluidized bed combustion boilers, municipal waste combustors, cogeneration facilities, and industrial processes such as steel, rock products, aluminum, and cement.

The decision to use baghouses over other particulate control devices such as electrostatic precipitators (ESP's) depends upon several factors. These include:
- Application
- Acidity of flue gas stream and materials being collected (ie. High sulfur coals)
- Particulate/Ash Resistively (Ease in collection in an ESP)
- Efficiency of collection required
- Operating Temperatures
- Requirement to collect metals and toxins such as Lead, Cadmium, Zinc, Dioxins, HCl and Mercury
- Fine Particulates (PM10, PM2.5)
A fabric filter system is very effective at the collection of fine particulates and metals. With additional
dry sorbents, air toxics such as mercury can be collected with substantially reduced injection rates of
sorbents over ESP's. Additionally when following Dry FGD systems, additional SO2 capture takes place across
the filter cake of the fabric which both enhances the total reduction across the system and at lower
consumption rates over a DFGD and ESP system.
HR-C baghouses are so effective because a wide variety of bag cleaning technologies and associated fabric
filter media are used to suit virtually all operations and dust characteristics. Filter types offered by
HR-C include pulse jet, reverse air, and COHPACTM (Compact Hybrid Particulate Collector) technologies.
