chinese manufacturers of oil boiler in china, full range of boiler products of ZOZEN boiler meet the needs of all industries

Improper water treatment is the leading cause of tube damage and poor performance in a boiler system. In this month, ZOZEN will discuss the consequences of introducing your boiler to hard water and the importance of utilizing a water softener.

chinese manufacturers of oil boiler in china, During the processing of broilers, whether it is retort sterilization, baking and cooking, or heating and drying, the heat source provided by the steam boiler is required. ZOZEN successfully won the full recognition of the Chia Tai Group with its systematic solutions, and became the  General Contractor of Jilin Zhengda Boiler, providing it with three 1.2 million kcal gas-fired thermal oil heaters, including pipe laying from the boiler room to the production floor.

chinese manufacturers of oil boiler in china, 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.

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, chinese manufacturers of oil boiler in china.

ZOZEN’s SZL series chain grate boiler has an independent water circulation system to ensure the safety and reliability of boiler’s water circulation. ZOZEN also designs independent water circulation systems in structure. The water circulation structure is simple and the division of water supply work is clear, which ensures that the cross-sectional area ratio of downcomer to riser is larger than 0.4 in order to ensure the safety of boiler’s water circulation under the premise that the water quality meets the GB standards.

The waveform stove furnace is an important part of the WNS series of oil-fired/gas-fired boiler. This part is directly exposed to the radiation of high-temperature flame and erosion of high-temperature flue gas. The use of the axial expansion and contraction of waveform stove furnace can reduce the thermal stress generated by the shell, tube plate and furnace itself, and more importantly, reduce the stress concentration caused by the elongation of furnace at the connection between furnace and tube plate. At the same time, the waveform stove furnace strengthens the flue gas disturbance, effectively improves the heat transfer effect of unit area and volume, and further improves the thermal efficiency of boiler.

Moreover, ZOZEN professionals provide full guidance from the installation and the trial operation of the boiler to the training of the boiler operator, so that each user can enjoy one-stop worry-free service from pre-sales to after-sales, chinese manufacturers of oil boiler in china.
