Isokinetic Probes

Steam chemistry, which mainly includes silica, conductivity, pH, chloride and fluoride, plays a major role in corrosion of high pressure boilers and turbines. These impurities attack on the HP, IP and LP turbines leading to blade erosion and corrosion. Stress corrosion cracking (SCC) of turbine blades is also a major issue. Thus impure steam can severely erode your profitability. A well-designed steam and water analysis system (SWAS) monitors the health of a power plant 24 hrs a day, 7 days a week. Proper analysis starts from proper extraction of samples. Forbes Marshall now brings a profitable solution in the form of Isokinetic Probes (Models ? Superheated Steam/Saturated Steam), designed to meet the SWAS requirements as per ASTM D1066. These probes are designed to extract saturated and superheated steam samples isokinetically at high temperatures and pressure, ensuring extraction of representative sample from the process steam lines. This helps to take immediate actions on water chemistry. Smart features: designed as per astm-d1066 and ASME PTC 19.11 standard practice for steam and water sampling systems; designed for supercritical power plants; rugged design, highly resistant to thermal and hydraulic shocks; easy to install; and eco-friendly material. Smart benefits: extracts steam isokinetically, i.e., sample extraction velocity of isokinetic probe is equal to steam velocity through process lines which ensures extraction of all impurities from process steam line; avoids sample contamination during extraction; and ensures true representative sample for accurate analysis in parts per billion (ppb) levels in case of silica, sodium analysis.
