The longitudinal seam automatic welding technology

The price of fuel is constantly fluctuating and with it comes creative ways to be more economical. Finding methods to be more energy efficient is never a waste of time. In the boiler room, efficiency improvements can be found by many sources, however, a common option for energy savings includes the use of an economizer. NOW, ZOZEN will help introduce the economizer. The economizer is a fabricated assembly of finned tubing that captures waste heat extracted from the boiler’s stack flue gases the exhaust that leaves the boiler stack.

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, commercial 4 ton condensing steam boiler dealer.

ZOZEN DZL series coal-fired steam boiler has sufficient output and high thermal efficiency. The boiler is packaged with a compact structure, so it has relatively low construction costs. The boiler is a horizontal three-pass water and fire tube chain grate boiler. In the single drum with a longitudinal layout, threaded smoke tubes from the convection heating surface, while the boiler drum and water-cooled walls on both sides form the radiation heating surface in the furnace. The boiler thermal efficiency can reach 82% and above.

The main advantage of circulating fluidized bed boilers lies in the direct control of pollutant discharge during the combustion process. This type of boiler adopts low-temperature combustion technology. The furnace temperature of a conventional boiler is as high as 1400-1500°C during combustion, while the furnace temperature of a circulating fluidized bed boiler is in the lower range of 800-900°C, which can reduce the generation of NOx; meanwhile, SOx can be removed during fuel combustion by adding low-cost limestone in the circulating fluidized bed boiler.

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, commercial 4 ton condensing steam boiler dealer.

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.

commercial 4 ton condensing steam boiler dealer, The two sides cooperated well for the steam boiler project in Bangladesh. ZOZEN will continue to provide high quality products for the global industrial boiler market in the future.
