In a wide range of industrial settings, from building materials and textiles to chemicals and food processing, the demand for reliable steam equipment continues to grow as manufacturers upgrade production capacity and improve energy efficiency.As industries evolve toward cleaner fuel use and higher energy utilization rates, companies increasingly look for project boiler solutions that combine precise engineering with proven reliability.

ZOZEN Boiler, an experienced industrial boiler manufacturer, has developed comprehensive systems tailored to different industrial conditions worldwide. Through advanced combustion technology, robust pressure-bearing structures, and flexible fuel adaptability, ZOZEN has become a trusted provider of project boiler solutions for demanding production lines. Its products serve not only domestic manufacturers but also users across Southeast Asia, South Asia, the Middle East, Africa, Europe, and South America.

Technical Strength of ZOZEN’s Project Boiler Solutions

To meet the diverse needs of project boiler applications, ZOZEN offers several key product series. Each series focuses on different fuel choices, operating environments, and steam requirements, ensuring that customers can implement an efficient and dependable system that supports long-term industrial development.

The DZW series is a representative biomass-fired project boiler that uses a reciprocating grate, making it particularly suitable for biomass fuels with varying humidity, size, and combustion characteristics. Its structural design typically incorporates a multi-drum arrangement that increases heating surface area and enhances steam generation stability. The reciprocating grate ensures continuous movement of fuel layers, enabling biomass to burn evenly and reducing the risk of clinker formation or fuel accumulation. This mechanical movement also helps mitigate the ash buildup that often occurs with fixed-grate systems.

The DZW project boiler integrates front and rear water-cooled walls, high-temperature-resistant refractory materials, and an optimized furnace chamber volume that encourages complete fuel combustion. With thermal efficiency generally reaching above 86% under standard biomass conditions, the boiler provides a cost-effective and environmentally friendly option for industries that rely heavily on steam.

Another prominent project boiler for biomass applications is the DZL three-drum series. This boiler adopts a chain grate firing system and a horizontal three-drum layout designed to improve heat transfer and long-term stability. Because the heating surface is distributed across multiple drums and convection banks, the boiler exhibits good load adaptability and consistent steam output. The three-drum structure strengthens water circulation, reducing risks associated with uneven heating and improving the boiler’s operational lifespan.

A key advantage of the DZL three-drum biomass project boiler is its ability to handle various types of biomass fuel such as wood chips, agricultural residues, and biomass pellets. Its grate zones are equipped with individually adjustable air chambers, allowing combustion air to be distributed based on fuel characteristics. This improves combustion efficiency, reduces unburned carbon content in ash, and supports fuel flexibility—a priority for many industrial users seeking long-term operational stability.

For projects requiring cleaner combustion and precise steam control, ZOZEN’s SZS series gas-fired steam boiler is a highly refined project boiler solution that adopts a D-type layout. With its large furnace chamber, efficient membrane walls, and well-organized convection tube bundles, this boiler supports strong heat transfer while maintaining reliable sealing performance. The furnace is arranged symmetrically to ensure uniform heating and stable flame development, and the large radiation surface promotes efficient combustion of natural gas or diesel.

The SZS project boiler incorporates an advanced burner that can adjust air–fuel ratios automatically to maintain optimal combustion conditions. When paired with economizers and condensers, the boiler’s thermal efficiency can reach above 98%, reducing long-term fuel consumption. The automated control system provides precise monitoring of steam pressure, water level, and flue gas temperature, helping users achieve stable steam output even in demanding production environments.

DZW Biomass Project Boiler Supporting a Building Materials Manufacturer

ZOZEN Boiler recently supplied a 19-ton DZW series three-drum biomass steam boiler to a building materials enterprise specializing in modern prefabricated construction materials. The company produces ALC autoclaved aerated concrete panels and AAC aerated concrete blocks, both of which require high-temperature steam for curing, shaping, and strengthening during the production cycle. In such facilities, a reliable project boiler is indispensable because steam uniformity directly affects material density, structural stability, and final product consistency.

The customer’s manufacturing processes depend on continuous supplies of high-temperature steam to complete autoclave curing stages. A biomass-fired project boiler aligns well with these requirements. By using biomass bulk fuel, the boiler supports reduced fuel expenses and helps the company improve its environmental footprint by lowering emissions associated with traditional fossil fuels. As the demand for sustainable construction materials grows, the ability to use renewable biomass fuel has become an important competitive strength in the building materials sector.

The DZW series project boiler selected for this application features a reciprocating grate and a three-drum arrangement, both of which improve fuel utilization and reduce operational difficulties associated with ash accumulation. Traditional biomass boilers can suffer from uneven burning and severe ash buildup, but the reciprocating grate design moves fuel gradually through the combustion zone. This prevents localized overheating, enhances mixing of fuel particles, and promotes more complete combustion. As a result, the building materials factory benefits from stable steam output, improved energy utilization, and longer maintenance intervals.

The installation of this project boiler strengthened the client’s production stability by ensuring dependable steam during each stage of curing and drying. The reliable thermal supply also supported improved product quality, as ALC and AAC materials require carefully controlled steam conditions to achieve uniform pore structure and appropriate compressive strength. By integrating a project boiler solution tailored to the factory’s production needs, ZOZEN helped the customer enhance competitiveness in a sector where environmental performance and production efficiency are becoming industry priorities.
