Introduction of SZS series gas-fired(oil-fired) steam boiler

SZS series boiler is designed with longitudinal double drums and " D " type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane water cooling tube wall. Furnace and tube bank are totally separated by the membrane water tube cooling wall at the left side of the furnace.

The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber,convection tube bank area and then from left front part enters spiral fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.

Features of SZS series gas-fired(oil-fired) steam boiler

1. By installing thermal insulation in the outlet of flue gas, we can reduce the boiler’s working noise. The furnace pressure is designed to be greater than 6000Pa.

2. The structural design focuses on details. The sealing of both sides of membrane wall and drums adopt comb plate. The boiler features a drainage system of condensation water in convection zone to prevent the corrosion of furnace body by acid condensate.

3. We adopts advanced automatic unionmelt welding process to ensure the welding quality. All the vertical and circular welding seams will be inspected by 100% X-ray detection.

4. The water circulation is enforced in the high temperature zone, which ensures efficient cooling in heating zone and prevent vaporization.

Boiler control and protection system

1, Program function modularization and efficient interlocking alarm function;

2, Automatic start and load PID automatic regulation function;

3, Fuel gas pressure abnormity fault interlock protection;

4, Automatic control function to water level (only for steam boiler);

5, Ultrahigh furnace temperature fault interlock protection (only for SZS boiler);
