ZOZEN SZS series gas-fired steam boiler project is located in the Uyuni Salt Lake, a salt marsh with the largest lithium reserves in the world. The boiler project will provide reliable heat source for the new plant of YLB and assist the development and commercialization of salt-lake resources.

As is known to all, Bolivia is a landlocked country located in the central and western part of South America. It has the highest average elevation in the world. The characteristics of high altitude, low air pressure and low oxygen content will affect the boiler combustion, heat transfer and flue gas characteristics. In addition, boilers that are designed under standard atmosphere pressure will inevitably have problems such as incomplete combustion, low thermal efficiency and insufficient output. So, it is necessary to take measures to improve the design of boilers.

ZOZEN fully considered the effects of altitude and atmospheric pressure on gas-fired steam boilers when designing the boiler system solution. On the one hand, owing to the decrease of atmospheric pressure, the combustion speed of fuel slowed down. The designers of ZOZEN properly increased the furnace volume and the convective heating surface area to ensure the heat transfer effect. On the other hand, the air volume and pressure should be modified when selecting a burner, which can ensure the boiler output and the thermal efficiency of the entire boiler system.

To ensure the superior quality of boilers, all processes are carried out in accordance with the technology design and require strict quality tests. Before delivery, a boiler needs to pass at least 7 acceptance tests such as flaw detection and hydraulic pressure test, which can find any small flaws and defects.

With strict quality control, ZOZEN paid great attention to details and kept a rigorous attitude for the choosing of boiler cover plates. Owing to the strong corrosiveness of the saline-alkali land in Bolivia, customers set strict requirements for the adhesion, weather resistance, film thickness, and color of the paint of boiler cover plates. ZOZEN gave top priority to the requirements of customers and carried out shot blasting on the cover plates. ZOZEN selected seawater-resistant primer which has excellent corrosion resistance and painted according to the color number and thickness provided by the customer. The boiler system was customized in strict accordance with customer requirements, which not only met the requirements of YLB but also got approval from the contractor and end customers.
