Pure Steam Generator
The machine consists of Main Heat Exchanger, Pre-Heaters, Feed Boiler Steam Inlet, Pure Steam Outlet Line, Multi Stage Feed Water Pump, Sampling Arrangements and Control Panel. The machine is based on Heat Exchange Method where boiler steam is utilized for the Feed Water to Pure & Pyrogen free Steam with online Conductivity <1.3µS/cm & output 500 Kg/Hr at pressure of 3.0 Kg/cm2. Pure Steam is distributed to various user points. Sanitary Steam Trap is installed at the end of the header to remove condensate from header.
STAGES OF PREPARATION The system designed to remove microbial contamination by Three Stage Separation. Stage 1: Feed Purified water is preheated by waste recovery method and enters the first effect from tube side. Specially designed distribution plate ensures the water falls down the tube as a “Thin film”. Stage 2: The falling film is heated with plant steam and causing it to a instant flash evaporation. Stage 3: This flash evaporation helps the steam to leave behind the heavier particles or droplets. (First Stage of Separation). This Transformation from water to steam significantly increases the velocity as it approaches the bottom of the column with high pressure.
