The SZS series boiler body is a double drum, vertical, chamber fired D-type layout structure, with the furnace on the right and the convection tube bundle on the left. Fix the boiler on the main chassis through the movable supports in the middle and at both ends of the lower drum, and ensure that the boiler expands as a whole towards both ends. The furnace is surrounded by narrow spaced tube membrane water-cooled walls, and the membrane water-cooled wall on the left side of the furnace completely seals and separates the furnace from the convection tube bundle. The rear of the convection tube bundle area is a sparse staggered structure, and the front is a sequential structure. The combustion of the furnace produces flue gas that enters the combustion chamber and convection tube bundle area from the exhaust port at the rear of the furnace, then turns from the front left side of the boiler to enter the spiral finned tube economizer and condenser, and finally enters the chimney and is discharged into the atmosphere.

The SZS type oil and gas boiler furnace water-cooled wall and convection flue all adopt membrane wall structure, which has good sealing performance, high heat absorption rate, and effectively reduces the use and maintenance workload of refractory bricks. This boiler uses high thermal resistance materials as insulation layers. Good insulation performance. The tail is equipped with an energy-saving condenser It can effectively reduce the exhaust temperature and improve the thermal efficiency of the boiler. The ultra-low nitrogen fully automatic combustion machine reduces harmful pollutants in the flue gas and operates without noise. And it has ignition program control and overpressure/shutdown protection functions, ensuring safe operation.
