Fire tube boilers also be called shell boiler, in the course of boiler operation, the high-temperature flue gas generated by the burner flows through the threaded pipe surrounded by water and heats the mixture of water, steam or soda outside the pipe wall to produce steam or hot water. SZS series gas-fired boilers are commonly used in chemical industry, medicine, paper, textile, food, electronics, automobile manufacturing and other industries.
Fire tube boiler drilling precision is high, high temperature zone, smoke box and other key parts of the expansion technology. ZOZEN boiler introduced CNC high-speed plane drilling and a complete set of Milling cutters from Germany for tube plate processing, which greatly improved the processing precision of tube hole and the surface finish of hole, and created good conditions for subsequent processing technology such as expanding tube. The raw material of ZOZEN boiler tube plate is made of customized steel plate, no matter it is 6 tons or 20 tons; it is made of whole steel plate. There is no jointing process, and the manufacturing cost is lower. At the same time, the design of opening hole does not need to consider avoiding welding seam, so the boiler produced is of higher quality.
At present, the textile industry accounts for 4.3% of the total industrial energy consumption. Whether dyeing, drying, sizing, printing and dyeing are inseparable from the boiler’s support and cooperation. Steam boiler is a member of the textile production line equipment, used to drive the drying equipment, and in the pressure sheet, singeing, desizing bleaching, shaping, dyeing and other links heating. ZOZEN boiler serves a number of small and medium-sized textile printing and dyeing enterprises, with many years of project experience in the industry. Because of the high fuel consumption of the textile industry, small and medium-sized textile mills tend to use small gas-steam boilers when considering the cost factor. Through the statistical analysis of customer cases, many textile printing and dyeing enterprises choose WNS and SZS steam boilers with quick installation structure, which have high combustion efficiency and high energy efficiency. Although the cost of gas-fired boiler is higher, especially the cost of boiler fuel, the thermal efficiency of condensing gas-fired boiler can reach 98%, and the environmental protection effect and energy saving and emission reduction effect are better.
ZOZEN SZS fire tube boiler is a two-drum, vertical, D-type arrangement. Around the chamber of a stove or furnace is membrane type water wall, furnace on the left side of the membrane type water wall sealing off the furnace and the convection bank completely, convection bank area at the back of the staggered structure for diarrhea, a front along the column structure, furnace flue gas from the chamber of a stove or furnace tail out of the smoke from the burning of mouth into the combustion chamber, convection bank state district, and then from point to spiral fin tube economizer of boiler on the left side of the front and condenser, finally enter into the chimney flue discharge into the atmosphere.
Each boiler has different characteristics. In the process of purchasing boilers, enterprises should choose the appropriate boiler type according to the actual production demand, such as steam demand, boiler room area, boiler operation cost and maintenance convenience, in addition to considering boiler price and boiler operation cost. Relying on advanced production technology and technical advantages, ZOZEN boiler has produced a number of series of high-quality fire-tube boiler products, which have been widely promoted and applied in all walks of life. Moreover, it can customize fire-tube boiler system for enterprises to meet different needs of users and provide one-stop service from design, manufacturing, installation, commissioning to training.
