ZOZEN SZS series gas/oil boiler body adopts large-area membrane wall structure, which effectively ensures air tightness and improves heat transfer efficiency. This gallery is the membrane wall assembly scene of boiler body. The area composed of a large area membrane wall is the hearth, and the other side is the upper and lower drums and convection tube bundles, which are completely sealed off from the hearth by membrane wall.
Membrane wall refers to the water wall composed of airtight tube screen welded by flat steel and pipes. Membrane wall can ensure that the furnace has good air tightness, which can significantly reduce the air leakage coefficient of the furnace and improve the combustion conditions in the furnace for negative pressure boilers.
SZS series gas-fired boiler is one of the popular boiler types of ZOZEN Boiler, which has the features of high heat efficiency, clean emission and full-automatic operation. This series of gas-fired boiler adopts large volume of combustion chamber and membrane structure, with sufficient combustion space and large heat transfer area, it effectively improves the fuel utilization rate.
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.
ZOZEN YY(Q)W series horizontal thermal oil heaters adopt special processing technology, and have wide fuel adaptability, suitable for natural gas, coal gas, blast furnace gas, heavy oil, light oil, etc. They have the advantages of safety, high efficiency, energy saving and environmental protection, and the thermal efficiency is over 95%.
