The SZS series oil/gas-fired steam boiler adopts a double-drum, water tube, longitudinally arranged D-type configuration. The furnace is positioned on the right side while the convection tube bank is located on the left. The bottom drum is secured to the main chassis through intermediate and end movable supports, which allow longitudinal thermal expansion towards both ends of the boiler.
The furnace is entirely enclosed by membrane water-cooled walls, with the left-side membrane wall forming a complete seal between the combustion chamber and convection section. The convection tube bank features staggered tube arrangement with sparse spacing in the rear portion and in-line tube alignment in the front section. Combustion flue gas exits the furnace through rear gas ports, sequentially passing through the post-combustion chamber, convection tube bank, then making a turn at the front-left section to flow through the spiral finned tube economizer and condenser, before finally being discharged into the atmosphere via the chimney.
1.Compact D-Type Design: The series adopts a double-drum "D-type" configuration, offering a space-saving footprint while ensuring optimal flame distribution and combustion efficiency.
2.Sealed Furnace Structure: The furnace is enclosed by membrane water-cooled walls and a fully welded, airtight inner casing, guaranteeing superior sealing performance of the furnace walls.
3.Stable Performance: A large heating surface area and ample steam-water separation space are designed to maintain stable boiler operation and consistent parameter output.
4.High Thermal Efficiency: Equipped with a flue gas condensing recovery system at the rear, it effectively lowers exhaust gas temperature, significantly enhancing thermal efficiency.
5.Premium Insulation & Aesthetics: High thermal-resistant insulation materials ensure excellent heat retention, while the pressed outer casing provides a sleek, visually appealing finish.
6.Easy Installation & Transport: Built with a modular quick-assembly design on a rigid heavy-duty steel base, the boiler simplifies installation and transportation.
7.User-Friendly Maintenance: Inspection openings on the furnace facilitate easy access for servicing, and explosion relief doors on the top enhance operational safety.
8.Automated & Safe Operation: Features a fully automatic burner and continuous electric water supply regulation for high combustion efficiency. Multiple safety protections ensure reliable and secure operation.
