Water tube boilers are a type of industrial boiler that has pipes (tubes) that are filled with water and are surrounded by hot gases to heat the water into steam. Water tube boilers are widely used in various industries, such as power generation, chemical, textile, food, paper, and more. Water tube boilers have many advantages, such as high efficiency, low emission, safety, reliability, durability, and maintainability.

Part 1:The consequences of choosing bad water tube boiler manufacturers

When you need to choose water tube boiler manufacturers, it is crucial to exercise caution and be meticulous in your selection process. Making the wrong choice can have severe consequences that can impact your industrial operations. Some of the potential consequences include:

1.1 Shorter boiler life span:

Bad water tube boiler manufacturers may have defects in design, material, or manufacturing, which may cause frequent breakdowns, corrosion, leakage, or explosion, and reduce the boiler life span significantly.

1.2 Lower boiler performance:

Bad water tube boiler manufacturers’s boilers may have low thermal efficiency, high fuel consumption, high emission, or unstable operation, which may affect the production efficiency, product quality, or environmental compliance of your industry.

1.3 After-sales maintenance issues and subsequent costs:

A substandard water tube boiler may require more maintenance, repair, or replacement, which may increase the boiler cost in the long run.But bad water tube boiler manufacturers will have some problems in these aspects.

Part 3:ZOZENs case

ZOZEN Boiler has many successful cases of water tube boilers at home and abroad, such as:

3.1 Customized 21 tons SZS Series Gas Steam Boiler for the YLB Lithium Carbonate Plant in Bolivia :

In terms of boiler equipment procurement, the YLB project leader maintained a cautious attitude and conducted market research before visiting the ZOZEN Boiler Yixing production base for on-site inspection, leading to a collaboration between the two parties. ZOZEN’s automated production and information management became the prerequisite guarantee for high-quality and high-performance boilers. ZOZEN’s technical personnel understood the actual production requirements of the YLB lithium carbonate plant and tailored a system solution for the SZS series gas steam boiler, taking into account the high altitude characteristics of the project location. This was achieved by scientifically selecting the burner, appropriately increasing the furnace volume and the heat transfer area of each convection heating surface, to ensure the steam boiler’s output and thermal efficiency.

3.2 8 ton SZL coal-fired boiler project in Pakistan’s feed industry:

The feed factory has decided to add rice husks to coal as boiler fuel for co-combustion, not only turning rice husks into valuable resources and promoting the recycling of biological resources, but also improving the company’s economic benefits. In response to the customer’s needs, ZOZEN Boiler has designed the feeding hopper, furnace grate width, length, and other aspects based on the characteristics of the “lignite + rice husk” fuel combination. They have customized the SZL series steam boiler system that suits their production line’s actual requirements. The thermal efficiency of this system is more than 5% higher compared to conventional boiler systems in the industry, achieving efficient conversion of thermal energy. Currently, the steam boiler has successfully arrived in Lahore, Pakistan, and installation has begun. Throughout the installation process, technical personnel from ZOZEN Boiler are on-site to provide guidance. The responsible person of the feed factory highly praises ZOZEN Boiler for their assistance.
