Angle-seat globe valves with flanged connections

GEMÜ Used mainly for the control and regulation of steam, water and slightly corrosive fluids, the Type 507 (manual operation) and Type 514 (pneumatically actuated) globe valves (photo) are now available with flanged connections in nominal sizes DN 15–50. The…

Save Fuel and Water with this Boiler Condensate Module

The planning, production and installation of high-pressure condensate systems used to be very complicated, but this firm has developed a compact module. The CSM-CC high-pressure condensate service module (photo) should be considered for a high-pressure condensate level of 50% and…

These new resins are an alternative to metal boiler components

In wall-hung condensing boilers for residential use, high-performance Noryl, Ultem and Cycoloy resins can replace traditional metals such as copper and brass used in boiler components, including condenser housings and manifolds. In high-efficiency condensing boilers, Noryl PPX resin offers an…

Reduce NOx emissions from boilers, regardless of fuel type

Hamworthy Peabody Combustion Suitable for use in package, industrial and utility boilers ranging from single to multi-burner wall-fired, Turbo and other boiler types, the ECOjet ultra-low NOx burners (photo) offer ultra-low (below 30 ppm NOx) emissions with little or no…

Heat Transfer Fluid Leaks: Break the Fire Triangle

Management of process plants requires the understanding and application of the fundamental tenets of safe design, construction, and operation of each facility. In that context, many years of practical experience with systems that use very high-temperature organic heat-transfer media has…

Heat Transfer Fluids: System Filtration

OVERVIEW Indirect heating of processes by organic thermal-liquid fluids offers highly reliable operation, and the heat transfer systems are generally treated as low-maintenance utilities. Occasionally, the heat transfer fluid can become contaminated, resulting in the formation of sludge particles, or…
