STILMAS – Steam Generator – PSG-DTS

MAIN FEATURES OF STILMAS PSG-DTS Instant start: pure Steam is immediately available thanks to the design of the”Accumulator boiler”technology. The unit can switch from standby to full capacity in seconds High flexibility: the production capacity can be automatically varied from 0 to 100% according to the request PRINCIPLE OF OPERATION The design of STILMAS PSG-DTS pure steam generators is based on the technology of the radiator. The system consists of two parallel bodies: the heat exchanger and the evaporator/decontamination column. The feed water is fed to the decontamination column (main body) while the industrial steam is fed to the supporting side of the heat exchanger. Industrial steam heats the feed water to the evaporation temperature, creating a strong circulation within the two bodies. REDUCTION OF NON-CONDENSABLE GASES (NCG) Stilmas has developed two alternative solutions to meet the NCG requirements of EN 285. The first solution consists of an intermediate tank in which the preheated feed water is sprayed by separating the liquid from the gas which is then extracted outside. CONSTRUCTION FEATURES The system is entirely made of AISI 316L stainless steel. the standard finish of the active surface is smooth and flush with passivation; mechanical or electrochemical polishing can be performed on request. The heat exchanger is of casing and tube type with double sheet metal execution; the tubes expand on the plates, avoiding any welding for a totally hygienic execution, and a better resistance to expansion efforts. The design and construction of the decontamination chamber, which is a completely empty column, ensure the best inspection ability. The absence of welds in this area drastically reduces the risk of corrosion, for a very long service life of the equipment. The overall design of the building, together with the decontamination process described, ensure a very compact design and require extremely limited space for maintenance. 400V, 50 Hz, ph: 3+N+T
