18tons boiler in paper factory, ZOZEN low-nox condensing boiler provides a new direction of green development for the chemical industry

18tons boiler in paper factory, ZOZEN Boiler (Wuxi) is a designated manufacturer of boilers and pressure vessels approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China. ZOZEN holds the A-grade boiler and BRⅡ-grade pressure vessel manufacture licenses, ASME “S” and “U” certificates with steel seals and fully passes the ISO9001:2000 international quality system certification.

On December 16, the owner and agents made a field visit of the informationalized plant of ZOZEN Boiler, and formally signed a purchasing contract with ZOZEN Boiler on the WNS series gas-fired hot water boilers.

The former part of ZOZEN SZL coal fired boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace there are dense convection tube bundles between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.

Based on the requirements of GB standard, the straight plug type water level electrode on the top of the furnace is added to prevent a shortage of water in the boiler due to wrong operation or other reasons. Advantages: avoid water shortage when the boiler is running.

ZOZEN Boiler has set up seven process stop points that are material re-inspection, material inspection number transfer, plate welding test, heat treatment, pre-expansion before welding, flaw detection inspection, hydrostatic test, which are inspected by seven responsible engineers. If any link is unqualified, it will not be able to proceed to the next process, which ensures that each ZOZEN boiler has the high quality, 18tons boiler in paper factory.

ZOZEN’s YLW series thermal oil heater is developed based on chain grate. It can provide high-temperature heat source at various temperatures below 350℃, suitable for various production processes such as dyeing, drying, slashing and printing which require high-temperature and low-pressure heating supply. The YLW series boiler also can realize the precise temperature control via advanced oil temperature and pressure control system to greatly improve the heat energy utilization rate. Recently, Kay & Emms has decided to upgrade the production equipment and signed a cooperative agreement with ZOZEN on the YLW series coal-fired thermal oil heater project.

All boilers are subject to damage if proper water treatment procedures are not followed. This is an important consideration both during operation and when the boiler is idle. To avoid damage and costly repairs, monitor water chemistry routinely and ensure that you are supplying your boiler with soft water at all times.
