SZS Series Water Tube Gas Fired Steam Boiler

The SZS series water-tube gas-fired steam boiler features a vertical D-type configuration with dual drums, incorporating energy-efficient heat recovery components in the exhaust section to maximize heat transfer surface area. The combustion system is front-wall mounted, while the convection tube banks are aligned parallel to the furnace chamber. Following combustion, flue gases travel through the rear furnace section, sequentially passing through the optional economizer, convection tube arrays, and rear heat exchange surfaces before final emission via the exhaust stack.
