Oil-fired steam boiler farming, greenhouse planting, seed factory, livestock slaughterhouse; chemical industry fertilizer factory, oil refinery, feed factory, painting factory, plastic factory, glass factory, glass factory, paper mill, textile industry Factory, Dairy Factory, Wine Factory, Food Factory, Shoe Factory, Ceramic Factory, Furniture Factory, Tire Factory, Cigarette Factory, Mat Factory, Chopstick Factory, Printing Factory, Tape Factory, Hardware Factory, Floor Factory, Cabinet Factory, Wooden Door Factory; bath, hotel, school, etc. Its functions: heating, heat preservation, drying, heating, smelting, supply production, disinfection and sterilization, vulcanization, hot water supply, etc. WNS4-1.25YQ oil fired boiler has a reasonable and compact structure, and meets the conditions for quick installation and delivery.
The body of the 4-ton oil-fired steam boiler adopts the lower furnace in the overall structure. The smoke pipes are arranged symmetrically on the left and right, and the drum is welded by the cylinder body of φ200×12 and the front and rear tube plates of φ2000×14. The first return of this series of steam boilers is a corrugated furnace, which is composed of a corrugated furnace of φ900×20; the use of a corrugated furnace structure not only increases the heat transfer area, but also satisfies the free expansion of the furnace after heating; the boiler re-combustion chamber It is composed of φ1400×14 inner front and inner rear tube sheets and φ1398×16 cylinder body welded together; the wet back form is adopted, which avoids the direct erosion of the rear smoke box by high temperature flue gas, and improves the reliability of boiler operation. The second and third return routes are respectively composed of 148 φ51×3 smoke pipes; the threaded smoke pipes can greatly enhance heat transfer, thereby reducing the heating area, making the boiler structure compact and saving steel.
The top of the WNS4-1.25YQ oil fired boiler is equipped with an economizer, which is composed of 168 φ32×3 spiral finned tubes. This greatly increases the heating surface and reduces the exhaust gas temperature of the boiler. The front and rear smoke boxes of this series of oil-fired boilers adopt an integral side-by-side door structure. This form has good integrity, beautiful appearance, and is generous. It is easy to open during maintenance and has good sealing performance. The aluminum silicate fiber board is used as the thermal insulation material, which has good thermal insulation performance, light weight, and convenient transportation and installation. There is an inspection device in the lower part of the smoke box, which is convenient for maintenance and maintenance.
The 4-ton oil-fired boiler is composed of pressurized body, base, packaging and insulation, flue, instrument valve and accessories, front smoke box, rear smoke box, platform ladder, energy saver and electric control system. This series of boilers has high safety, large steam space and easy maintenance. WNS series boilers are manufactured according to specifications, long life and durable, and comply with environmental protection. At the same time, it adopts reliable accessories, advanced control system and high-quality service.
WNS4-1.25YQ oil fired boiler is fully automatic operation, integrated design and reasonable design. This series of steam boilers adopts the technology of inserting turbulators in the flue tube, which enhances the disturbance of flue gas in the tube, destroys the laminar boundary layer, greatly improves the convective heat transfer coefficient, and strengthens heat transfer. Reduce boiler exhaust gas temperature, improve boiler efficiency and save fuel.
