Fire-Tube boiler series SM/SG

Home > Products > Steam generators > Fire tubes > Fire-Tube boiler series SM/SG

SG and SM series fire-tube steam generators represent the ideal solution for reducing electrical consumption, increase the degree of safety of the plant – also in case of unsupervised operation – and comply with new emission regulation, using simple, yet reliable electronics.

Highly customizable solution for steam production from 1 to 30 tons/h, these series of steam generators is characterized by a complete shielding of the inversion chamber with a water tube enclosure, which, compared to other types of boilers, ensures a fast access to the flue gas inversion chamber and a complete visibility of the tubes, tubesheet and combustion chamber.

The advantages of this series stem from its design, with large heated surfaces and combustion chamber, as well as high turbulence of the flue gas flow, which ensures high thermal efficiency and low emissions.

Features

Tubes expanded and welded to the tube-sheet protecting the tubes from any aggressive delayed combustion
Tubesheets with ledges to guarantee maximum quality of welding between sheet and tubes.
Complete absence of refractory material and connecting rods on the shielding to avoid stress on the tubesheet
Wide combustion chamber guaranteeing low thermal load and reduced emissions
Available design for saturated and superheated steam, as well as hot water production

Competitive advantages

Ease of access to the internal parts of the boiler, furnace, tubesheet and flue gas inversion chamber.
Heat exchange optimization
High thermal efficiency up to 96%
Low NO_x emission level, under 80 mg/Nm³, achieved through an optimized combustion and the employment of low
NO_x burners specifically design for the steam generators.
Integrated electronic control system for dynamic management and control of the boiler, guaranteeing maximum safety and improved performances even in case of unattended operation for 24/72h.
Opportunity to interconnect with smart factory
Possibility to exempt from supervision for 24/72h
