low nitrogen condensing oil hot water boiler principle, ZOZEN boiler actively prepares for the spring recruitment season

As a leading manufacturer of industrial boilers, ZOZEN has a network of sales around the world. Recently, ZOZEN mid-temperature and mid-pressure steam boiler project in Bangladesh was in full swing.

low nitrogen condensing oil hot water boiler principle, Recently, relying on its solid strength, ZOZEN attracted the international fiber industry giant Lanjing Group to visit and inspect, and signed a long-term cooperation agreement with the company. Lanjing (Nanjing) Fiber Inspection Team stated that the visit was mainly due to the need to build distributed energy sources and plans to introduce multiple gas boilers. After understanding the company's actual needs, ZOZEN recommended SZS series gas-fired boilers for Lanjing (Nanjing) Fiber.

The WNS series oil-fired/gas-fired boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation, low nitrogen condensing oil hot water boiler principle.

PT.Sari Incofood Corporation is a leading manufacturer of instant coffee drink in Indonesia. The company was eager to upgrade renew backward equipment. Among them, the steam boiler provides heating support for the production process of coffee pulping, liquid coffee concentrating and coffee freeze drying. To meet the requirements of the actual production line, ZOZEN recommended the SZL series water tube boiler for the company. The boiler has been stably running up to now, so the company spoke highly of ZOZEN products and technology.

The grate bracket of ZOZEN’s chain grate boilers adopts double-layer structure. The lower layer uses channel steel and the upper layer uses light rail. The upper layer is heated and the lower layer is stressed. It changes the traditional grate bracket using angle steel and friction strips without  deformation. The active grate runs on the light rail with a 72-hour cold test run carried out before leaving the factory to ensure the smooth operation of grate without deviation or jamming.

After the raw materials are transported to the workshop, steel plates will be precisely cut by the plasma cutting machine according to design drawings. The cut steel plates after finishing three processes of rust removing, edge milling and chamfering will be rolled into workpieces for making drums by this advanced four-axis rolling machine. ZOZEN’s CNC rolling machine can complete the rolling of a drum shell within 90 seconds with a largest thickness of 100mm, an out-of-roundness and angular deviation within 1mm. Its advantages include the predeformation and cylindrical rolling of two plate ends via one-time load, arc work, shaping and leveling work on the sheet metal. It has the effects of direct pre-bending, saving time and materials to ensure the smooth progress of next welding process and further ensure the welding quality, low nitrogen condensing oil hot water boiler principle.

After the golden period of rapid development, China’s equipment manufacturing industry is undergoing a transformation and upgrading. ZOZEN also conforms to the trend of the times and welcomes the reform. ZOZEN thinks that innovation may not mean the new products, but more accurately a concept. The innovation of product, management and system is to keep the development vitality of enterprise and provide higher quality and standards for the industrial boiler industry.
