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…
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…
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…
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…
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…
Although proper water treatment and conditioning for combined-cycle units and standalone steam generators are vitally important for reliability in the chemical process industries (CPI), a well maintained and operated steam generator can also save the facility much money with regard…
ESCO Technologies Boiler-tube expanders with precise torque control A full line of air-powered tube expanders and rolling motors for creating steel-to-steel mechanical seals in boilers, heat exchangers and condensers is available for sale or rent from this company. The Millhog…
The research group of Kazuo Tajima at Kanagawa University (Yokohama, Japan; apchem2.kanagawa-u.ac.jp) have developed a new emulsification process that enables biodiesel fuels (BDFs) to be used without any purification process, thereby reducing production costs by one fourth. Tajima estimates that…
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…
Acoustic coupling in industrial furnaces is an issue that appears to have become more prevalent as designs increase the volumetric heat density of furnaces, and burner technology is required to meet more-stringent emission requirements. The problems associated with acoustic coupling…
