Description

Steam and water analysis system (SWAS) — A well designed Steam and Water Analysis system (SWAS) can help in monitoring the critical parameters in the steam. These parameters include pH, conductivity, silica, sodium, dissolved oxygen, phosphate and chlorides. A well designed SWAS must ensure that the sample is representative till the point of analysis. The SWAS system comprised of shelters, walk-way, rack mounted, panel mounted designed as per the customer requirements are the best suited for power plants. These are safe for use, provide good working area for user & system expert, yet protects the equipment from unauthorised usage / fiddling. Hence Steam Equipments designed new concept of FIT SWAS (Fully Integrated Steam & Water Analysis System).We have designed & developed Steam & water analysis system in accordance with the recommendations of ASME PTC 19.11 Part-II.

Modular System

Description

Modular sampling panels for primary sampling and secondary sampling; Primary sampling module includes inlet isolation valve, blow down valve, sample cooler with cooling water inlet and outlet valve with coolant flow indicator to diagnose required flow of cooling water. Pressure reduction and high sample temperature safety valve (thermal shut off valve).

Primary cooling sampling panel consists of rotameter, Back Pressure Regulator, Pressure Gauge, Temperature Gauge and Grab Valve with Tundish.

For conditioning scheme of both, primary and secondary panel- secondary panel includes Secondary Sample Cooler with chilled water inlet and outlet valve with chilled water Flow Indicator, Rotameter, Back Pressure Regulator, Pressure Gauge, Temperature Gauge and Grab Valve with Tundish. The chiller unit is skid mounted modular type, it’s a separate unit which will be connected to secondary cooler chilled water inlet and outlet connections.
