best water boilers, the advanced manufacturing process of ZOZEN automatic gas-fired boilers has triggered the concerns of the building industry

As a domestic well-known industrial boiler manufacturer, ZOZEN has been implementing the Belt and Road initiative all the time. The booming development in overseas market of ZOZEN profits from insisting on technological innovation and cultivating professional technical service team for overseas market.

In the process of smelting molten steel, pouring steel ingots, and producing finished castings, a large amount of steam is consumed. The superheated steam generated by the boiler provides the required thermal energy for its process. Through open bidding, ZOZEN stood out among many boiler manufacturing enterprises with its own technical advantages and quality assurance, and provided China Second Heavy Machinery Group Corporation with a large superheated steam boiler.

The SZS series gas-fired hot water boiler adopts the forced circulation in the high-temperature zone in the boiler proper to ensure that the heating surface of each part can be reliably cooled without vaporization and also ensure the safe and stable boiler operation. The use of clean energy natural gas, combined with a large furnace space and an advanced low-NOx burner, can ensure the sufficient fuel combustion and make the NOx emission in the boiler exhaust gas less than 30mg/m3 to reduce the environmental pollution, best water boilers.

best water boilers, 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.

The key processing technologies of the steel plate of ZOZEN gas fired boiler, such as the slanting of the steel plate, the circle, and the drilling of the drum, all adopt advanced CNC processing technology to reduce assembly stress and extend the service life of the boiler. Process to ensure welding quality, all longitudinal and circumferential welds are 100% radiographically inspected.

In the rubber industry, steam boilers are widely used in the processes of rubber calendering, vulcanizing and drying. PT.Industri Karet Deli is a large rubber enterprise in Indonesia, it planned to upgrade production equipment to improve their core competence. The company contacted ZOZEN and signed the purchase contract of SZL 20 tph SZL series coal-fired boiler. This series of water tube boilers adopts unique grate bars and appropriate air registers to ensure the stable running of boilers and improve the thermal efficiency.

In order to attack the COVID-19, ZOZEN Boiler gave priority to medical materials manufacturing enterprises and other units on product supply. ZOZEN had completed the delivery of boiler proper and auxiliary machinery of WNS oil-fired steam boiler in two batches on March 18 and April 2. ZOZEN would work together with Ansell to make contributions to fighting against the COVID-19.
