There are typically three types of ESP units: dry negative corona units, wet negative corona units and wet positive corona units. Dry negative corona units have inherently better voltage/current characteristics, are utilized more frequently and will be the main focus of this website; however, wet negative corona units will be discussed for their applicative differences. The following is a small list of typical industrial applications for ESPs.
- Refuse & sewerage sludge dryers and incinerators
- Coal- and oil-fired boilers, coal driers and coal mills
- Production plants for the cement, limestone, gypsum, pulp and paper industry (kilns, mills, driers and coolers)
- Electro-metallurgical, chemical, gas and detergent manufacturing plants
- SO2, SO3, acid mist and ammonia control (wet ESPs)
- ESPs are very efficient (up to 99% efficiency), even for small particles
They are generally more economical than other particulate control devices:
- Operating costs are reduced by low energy consumption, minimal maintenance requirements and reduced cost on spare parts
- Can be designed to handle wet and dry gas compositions for a wide range of gas temperatures
- Can handle large volumes of gas flow with low pressure drop
The salient features of the ESPs we offer include:
- Horizontal and vertical flow precipitators.
- Dry type designs for gas volumes, from as little as 5,000 m3/hr to 1, 00,000 m3/hr.
- Wet type designs for maximum particulate removal.
- Hot gas designs for operation at temperatures above 450oC.
- ESPs for diverse applications like corrosive gas, tar and other difficult material etc.
