Thermal oil heaters are widely used in chemical industry, printing and dyeing, edible oil processing and other industries because of their low pressure, high temperature and precise temperature control. ZOZEN gas-fired thermal oil heater adopts multi-loop round coil structure, with large heat exchange area, high thermal efficiency and fully automatic and safe operation.
ZOZEN SZS series gas-fired and oil-fired boiler is a kind of horizontal internal combustion structure. The size of the steam drum and water drum is calculated professionally, and the steam drum is equipped with several steam-water separation devices, which can effectively improve the steam quality.
ZOZEN WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas-fired boiler. Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power the stress and expand boilers working life.
In response to increasingly serious environmental problems, Ji Xiang Ju Food decides to purchase low NOx and eco-friendly gas-fired steam boiler. To meet the new requirements, ZOZEN Boiler customizes the boiler system and recommends SZS series low NOx steam boiler to ensure the sufficient heat supply for Ji Xiang Ju Food's production line. This series of gas-fired boiler adopts D-model full membrane wall structure and combustion chamber adopts narrow-spacing tube membrane wall with good air impermeability to reduce heat loss and enhance the thermal efficiency to 98% and above with the economizer at the end of flue gas duct.
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 YLW series horizontal thermal oil heaters have wide fuel adaptability, applicable to a wide range of fuels including bituminous coal, anthracite and biomass particles; they adopt the design of square coil for sufficient heating surface, which is safe and efficient, and the thermal efficiency is leading in the boiler industry.
In the pharmaceutical industry, steam is one of the important energy sources for pharmaceutical companies to produce heat for heating, concentration, drying and other processing steps in pharmaceutical production. ZOZEN 10 tph WNS series condensing gas-fired steam boiler has been successfully put into production after installation and commissioning. This condensing gas-fired steam boiler not only produces high-temperature saturated steam, but also can adjust the multi-speed according to the dema...
