D type boiler Brief Introduction
ZG is a supplier and manufacturer of SZS d type boilers for 7 decades. SZS series D type boiler which is of double drum, longitudinal type, natural circulation, fast-assembling, oil or gas fired water pipe, quick fitting structure and delivered in complete set. This kind of boiler is with high thermal efficiency, reliable and safe operation, small volume, light in weight, short period of installation. Also it is with small thermal inertia, fast heating up, lifting pressure, and timely start / stop and stable combustion performance.
D type boiler design:
SZS series of boiler are design by double drum, longitudinal type, full water pipe structure. It is consist of the upper and lower drum, convection bank and the left and right set of boxes. The total size are close-knit, and the external appearance is elegant and beautiful. It apply to com-bust under slightly negative pressure because the water screen of the boiler furnace is use of close-packed structure with perfect tightness.
For more SZS D type boiler system: http://www.zghorizontalboiler.com/The-double-drum-d-type-structure-of-SZS-series-boiler.html SZS series boiler is in D type arrangement, there is a burner in front of the furnace, so the effective area of the furnace are increased. Before high temperature gas is emitted through the chimney into the air from the economizer, they will loop through the furnace , over-heater, convection bank. The circulating in the convection bank between the upper and lower drum are belong to natural circulation, It is typical and high reliability natural water circulating structure, have high self-compensation, automatic allocation feature for ratio of rise and fall, so the water circulating is reliable and safety. And the convection bank also immensely increase the heating area, the economizer is protected by it because water in the convection bank Absorbed more thermal, the temperature of the gas through the
