Steinmüller Engineering - Waste Heat Boiler
Alfa Laval Olmi synloop boilers effectively cool effluent gas from the ammonia converter, recovering and reusing waste heat to produce medium to high pressure steam for use by the steam turbines. For high temperature and high pressure applications such as ammonia synthesis in mind, let Alfa Laval Olmi process gas boilers do the job.

Failures in Ammonia Plant Vertical Waste Heat Boilers Potential Causes & Remedies The authors were involved in investigations of corrosion problems in Ammonia plant Waste Heat Boilers that had in common, that deposits on the water/steam side were noticed
Our waste heat recovery systems, waste heat boilers, synloop boilers, steam superheaters and feed water preheaters are used for process stages in ammonia, methanol, hydrogen and gasification plants. BORSIG stands for leading technologies made in Germany, highest quality, reliability and state-of-the-art production methods and innovations.
Synloop Boilers. The KNM Group's Borsig HOT/COLD tubesheet design for synloop waste heat boilers are highly demanded for their waste heat recovery systems in ammonia plants. U-tubes with hot and cold ends are alternately arranged. The hot shank is surrounded by cold shanks. Advantage of this design is that the tubesheet and the hot end tube
The gas cooling and heat recovery are best taken care of in a loop boiler and the design of this boiler must address the special challenges effectively. The loop boiler is both used to initiate the final cooling of the ammonia-rich gas or as interstage cooling between two converters, for instance, an S-200/300 followed by an S-50 converter.

Synloop and refrigeration section reported highest downtime days of 157.6 days and contributed 25.6% to the total downtime for 3 years period. Problems in waste heat boiler (WHB) were encountered by eight plants and contributed 48.2% of the downtime in
SyNLOOP WASTE HEAT BOILERS IN AMMONIA PLANTS 1: Ferritic tubes are used, which are not sensitive to stress corrosion cracking, contrary to Incoloy tubes 2: unique patented HOT/COLD tube arrangement which results in tubesheet temperatures
the total downtime. Nine plants faced problems related to waste heat boiler which accounted for almost 70% (85.4 days of 122.5 days) of downtime in secondary reformer section. One of the plants Table 2 – Reasons for loss of production in ammonia plants
2021/2/1 · Abstract. The primary Waste Heat Boiler (WHB) in an ammonia plant experienced cap leaking and the outer tube rupture after ten months since the last repair and replacement (total retubing). The leaking cap and the outer tube materials are low carbon steel SA-204 Gr. B and SA-209 Gr. T1a. The inappropriate vertical part of the leaked cap, which
Secondary Waste Heat Boiler (102-C) for further generation of HP steam. See Figure 1 for process flow diagram. Figure 1: Process Gas flow diagram Water flows from steam drum (101-F) through one down-comer into water chamber where it enters the inner
Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, C. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
The primary Waste Heat Boiler (WHB) in an ammonia plant experienced cap leaking and the outer tube rupture after ten months since the last repair and replacement (total retubing). The leaking cap and the outer tube materials are low carbon steel SA-204 Gr. B
Reformed gas waste heat boiler For technical and economic reasons the maximum ca-pacity of a single reformed gas waste heat boiler is about 3800 mtpd, thus a dual flow design has to be chosen for larger plants. For a 4000 mtpd plant one of these boilers will
as waste heat recovery systems, waste heat boilers for ammonia, methanol and hydrogen plants, synloop waste heat boilers etc. Casale Established in 1921, Casale greatly contributed to the history of ammonia production and nowadays is a world
A waste heat recovery boiler refers to a heat recovery equipment that is utilized for minimizing the wastage of heat generated by industrial plants. It is primarily used by the factories producing steel, cement, non-ferrous metals and chemicals, such as ethylene, ammonia, sulfuric acid and nitric acid.
