Electrostatic precipitator
An electrostatic precipitator (ESP) removes particles from a gas stream by using electrical energy to charge particles either positively or negatively. The charged particles are then attracted to collector plates carrying the opposite charge. The collected particles may be removed from the collector plates as dry material (dry ESPs).
ESPs designed & Supplied by Dynepro Private lImited are capable of collection efficiencies greater than 99 percent.
An ESP is primarily made up of the following four components: gas distribution plates, discharge electrodes, collection surfaces (either plates or pipes) and rappers. The gas distribution plates consist of several perforated plates which help maintain proper flow distribution of the entering gas stream. The discharge electrodes are divided into fields. Most ESPs have three or four fields in series; however, very large units may have as many as fourteen fields in series. Discharge electrodes are energized by a single transformer-rectifier (T-R) set power supply. The energized electrodes create ions that collide with the particles and apply the electrical charge to the particles contained in the incoming gas stream. The collection plates or pipes provide the collection surfaces for the charged particulate matter. The rapping system is responsible for removing the collected particulate matter from the collection surfaces.
Dynepro’s ESPs are designed with Optimum Aspect ratio , Migration velocity & Treatment time taking in to account of various factors & Characteristics of the Flue gas, its particle size, particle resistivity etc.,
Thus, the design is able to achieve the deliverables of desired outlet dust concentration to meet the statutory norms with increased Collection Efficiency.
The Technical team of the ESP division has the expertise of having designed more than 300 ESP’s across the nation.
Concept to Commissioning to reduce Carbon foot print
Dynepro’s Technology team has offered a sustainable solution to a glass major to recover the heat from waste gases exhausting from their float to generate 1 MW of power.
The nitrogen rich gas of around 85000 Nm^3 per hour with a temperature of 400 to 420 Deg C exhausting from the process is let in to a Single drum bottom supported Vertical design water tube boiler equipped with an array of heat transfer areas like Evaporator, Economizer and Superheater.
The steam of 9.8 TPH at 25 Kg/Sqcm (g) pressure and 230+/-10 Deg C Superheat is generated which is then let in to a multistage straight condensing Steam turbine with integrally geared radial split with built up rotor construction which is the optimum selection for this application.
The generator is of 11 KV output.
The complete system is equipped with all Safety features and being operated through PLC based control system.
This solution has achieved higher efficiency in recovering the waste heat from waste gases by maximizing the energy output and becoming more sustainable by reducing its carbon footprint.
