The VT CORP Electrostatic Precipitator was introduced, considering the increasing demand for environmental protection. VT CORP has credentials of satisfactory performance of more than 500 ESPs in India and globally.
The VT CORP’s Electrostatic Precipitator is upgrading itself over the past 2 Decades considering the stringent demand for environmental protection. The precipitator technology is constantly optimized as per the environmental norms for several years. The precipitator is technically superior and the most preferred dedusting system for numerous applications.
Dust concentrations at the precipitator inlet of several hundred grams per Nm3 can be reduced to a few mg/Nm3 at the precipitator outlet, e.g. to 20 mg/Nm3 or even lower as per application.
The electrostatic precipitator is suitable for the precipitation of solid particles. The particles are charged by a flow of ions from the discharge electrode and drift under the influence of the electrical field towards the collecting electrode. The cleaning of the collecting electrodes is achieved by periodic rapping for dry precipitators and by flushing for wet precipitators. The theoretical basis for the design of electrostatic precipitators was worked out for the first time in a study concerning the motion and charging of electrical carriers in cylindrical capacitors.
Various factors for precipitator sizing cannot be calculated; they are based on the experience. The specific electrical resistivity of the dust is the most important criteria for the determination of the precipitator size.
Specially Designed ‘X’ – Type Gas Distribution Plates for Even distribution of the incoming gas flow throughout the cross-section of the precipitator and to reduce the overall pressure loss to the optimum level. The ESP casing and supporting structure is designed to withstand various temperatures and pressure conditions. The supporting structure made from sectional steel consists of a system of fixed and movable supports, which permits compensation of the thermal expansion of the casing. Optimization of the Discharge and Collecting System by means of VT-240 Collecting Electrode and Discharge Electrode Type ‘Emitron-15’ & ‘Star’ Electrode. Effective Mechanical Rapping Mechanism for Collecting Electrode, Discharge Electrode, and Gas Distribution Plates. The microprocessor-based HVR Control system offers a quicker and differentiated response to changes in the prevailing electrical conditions in the precipitator.
Cement plants. Coal and oil-fired boilers, coal mills, and coal driers. Incinerators. Boilers in power generation plants. Co–gen plants in sugar and pulp and paper industry. Biomass fired boilers in the renewable energy industry. Various exhaust applications in steel processing plants.Single field ESP is ESP with only one field (Normally ESP has more has 2 or 3 field). Internal arrangement is same as regular ESP i.e.Rows of collection electrode and discharge electrode with their respective rapping systems.
Inlet dust burden is very low i.e. 500 to 700 mg/Nm3. Coarser particles are already collected in cyclone/dust collector prior to entering the ESP; hence ESP has to handle only finer particles. Currently Outlet emission required is only 150mg/Nm3 and in palm oil mills (Inlet dust burden is 700mg/Nm3) which is approx. 80% efficiency of the ESP in worst condition and 70% efficiency in normal condition.This requirement is far lower than standard requirement of 90% efficiency per field.As there are no coarser particles and dust burden is very low, the concentrated current from the discharge electrodes is not be required. Hence V T CORP developed Star type electrodes for such applications which discharges uniform current distribution to capture the fine dust from the Flue gas.
Compact in size and therefore easily accommodate in the available space. Create a space for future expansion to adhere future stricter to emission norms(<50 mg/Nm3) Economical and easy to install at the existing Boilers, where ESP is now mandatory to install to adhere to current Emission Norms.
