High pressure packaged superheated boiler TRYSUHR'

High pressure packaged superheated boiler, genuine three-pass fire tube, horizontal, 91% efficiency (1).

TRYSUHR’ is a family of packaged smoke tube superheated boilers, genuine three-pass, and wet back. Standard safety pressure up to 10 bar (higher pressure available on request) and output from 870 to 10000 kW. It can be operated with liquid or gaseous fuels. Every model is complete with regulations and safety accessories for automatic operation and easy commissioning. 

In compliance to the current laws, each superheated boiler undergoes a conformity assessment, carried out by a Notified Body. The conformance to the essential safety requirements demanded by the European Pressure Equipment Directive 2014/68/UE (PED) is guaranteed by the CE mark.

Design features

By means of the three-pass design the smoke gases in the combustion chamber are diverted to the front through the first set of fire tubes by the reversing chamber; then reversed again by the frontal smoke box to the second smoke tube sections and discharged through the chimney connection. The appliance is designed to ensure low heating loads in the combustion chamber, low superficial loads and low NOx emissions (with Low NOx burners).

• Boiler body: is made of a cylindrical shell and a wet back furnace, dished and butt welded tube plates, made of high quality steel. All the materials have certificates attesting their chemical and mechanical characteristics, the controls are carried out during each production stage, and, theirs suitability for use as well. The welding seams are carried out by qualified personnel in compliance to certified procedures and are subjected to Non Destructive Tests, in accordance to an internal “Manufacturing and Control” program. Once the boilers have been manufactured they are subjected to hydraulic testing in accordance to the requirement 7.4 – Annex I, laid down in the Directive 2014/68/UE (PED).
• Smoke tubes: made of high quality steel, are welded to tube plates, and are without helical turbulators.
• Reversing chamber: is built in welded steel plate, completely water-cooled, and connected to the rear smoke-box with supports and manhole.
• Front door: is built in welded steel plate, completely cladded internally with a layer of insulation material and with a layer of high density refractory material. One or two doors are present according the boiler’s capacity, for cleaning and inspection. Close to the burner hole is present a self-cleaning sight glass for combustion control during boiler operation.
• Rear smoke-box: is built in welded steel plate, completely cladded internally with a layer of insulation material and with a layer of high density refractory material. Two doors for cleaning and inspection are fitted with hinges to be quickly opened. Complete with an horizontal chimney connection with a diameter sized to the boiler’s output, and a self-cleaning sight glass for combustion control. The rear smoke-box can be accessorized with and external economizer.
• The base: is built with a steel frame, welded to the tube plates and closed with steel plates. 
• Walkway: positioned on the top part of the boiler, is made of steel, covered with chequered plate and completed; on request with handrail and access ladder.
• Insulation: the shell is thermally insulated with a 100 mm rock wool cladding binded with high density, thick thermosetting resins, suitably supported and covered externally in 10/10 thick enamelled aluminum.
