4 Ton Steam Boiler Price: Efficient Industrial Solutions from ZOZEN Boiler

The demand for efficient and cost-effective steam generation equipment continues to rise as industrial production scales up across various sectors. Among them, the 4 ton steam boiler has become one of the most popular choices for medium-sized enterprises. It provides sufficient steam capacity for production processes such as heating, drying, molding, and sterilization. When enterprises begin to inquire about the 4 ton steam boiler price, they often find that it varies significantly across manufacturers and configurations.

Generally, the 4 ton steam boiler price is influenced by multiple factors, including the type of fuel used, boiler structure, manufacturing quality, material selection, automation level, and after-sales service.With advanced design capabilities and a complete product portfolio, ZOZEN provides a range of 4-ton steam boiler models that combine efficiency, reliability, and environmental responsibility. Among its most sought-after products are the DZL series biomass steam boiler and the WNS series gas/oil steam boiler, both of which represent excellent choices for enterprises comparing the 4 ton steam boiler price in relation to performance and long-term value.

ZOZEN DZL Series Biomass Steam Boiler: Reliable and Efficient for Medium-Sized Enterprises

The DZL series single-drum biomass steam boiler is one of ZOZEN’s core products, widely recognized for its robust performance and adaptability to various biomass fuels. Designed for small to medium industrial users, this boiler type provides a dependable heat source while utilizing renewable energy.

As a water-fire tube combination boiler, the DZL model integrates advanced combustion technology with an efficient heat exchange design. The boiler uses compressed biomass pellets as the primary fuel, offering a renewable and environmentally friendly energy solution. Its 4 ton capacity makes it particularly suitable for industries such as food processing, plastics, packaging, feed production, and building materials manufacturing, where steam demand is moderate but continuous.

The structure of the DZL series is compact and space-efficient, featuring a horizontal layout with a single drum and a chain grate furnace. This design ensures even fuel distribution and stable combustion. The furnace arch and air distribution system are engineered based on the characteristics of biomass fuel, ensuring complete combustion while minimizing unburned carbon.

One of the key design highlights is the threaded smoke tube, a proprietary ZOZEN technology that enhances heat transfer by creating turbulence within the flue gas. This innovation significantly improves thermal efficiency, helping the boiler achieve steady output and reduced fuel consumption. Meanwhile, the three-pass water-fire tube configuration solves the common issue of tube plate cracking in traditional fire-tube boilers, improving both safety and longevity.This performance-to-price ratio makes the DZL series a practical and sustainable option within the 4 ton steam boiler price range.

WNS Series Gas/Oil Steam Boiler: High Efficiency with Clean Energy

For enterprises that prefer clean-burning fuels such as natural gas, diesel, or light oil, the WNS series gas/oil steam boiler from ZOZEN offers a refined balance between performance, energy efficiency, and low emissions. This boiler features a horizontal, internal combustion, three-pass wet-back design, ensuring full fuel combustion and effective heat utilization.

The WNS series is equipped with advanced low-NOx burners, which reduce nitrogen oxide emissions to below 30 mg/Nm³, complying with global environmental standards. The large-diameter corrugated furnace enhances radiation heat absorption and accommodates thermal expansion, while the threaded flue tubes strengthen convection heat transfer, maximizing efficiency.

In typical operation, the WNS 4 ton steam boiler can achieve a thermal efficiency of up to 98%, depending on the specific operating conditions and fuel type. The wet-back structure improves rear-end sealing, minimizes heat loss, and ensures long service life. ZOZEN’s intelligent control system further enhances safety and automation by allowing real-time monitoring, pressure regulation, and fault diagnostics.

When analyzing the 4 ton steam boiler price, many enterprises also consider the lifecycle cost rather than just the upfront investment. In this regard, the WNS series offers long-term economic benefits by reducing fuel consumption and maintenance costs.

4-Ton Biomass Steam Boiler for a Plastic Products Manufacturer

Steam plays a crucial role in the production of plastic products, especially during heating, molding, and shaping processes. Stable and sufficient steam supply directly affects the precision and quality of plastic components. A well-known plastic products factory, specializing in the manufacturing of foam boxes, insulation panels, and EPE packaging materials, needed to upgrade its energy system to support its expanding production capacity.

After assessing the company’s energy demands and production characteristics, ZOZEN Boiler recommended a 4 ton DZL series biomass steam boiler. The system was designed to provide reliable and efficient steam for the factory’s continuous production lines.

This boiler operates on biomass pellet fuel, which not only reduces operational costs but also minimizes carbon emissions. Its compact structure allows for easier installation within limited plant space. The threaded smoke tubes enhance heat transfer, while the optimized furnace arch ensures full combustion of biomass fuel. As a result, the system achieves stable steam generation and efficient thermal conversion, meeting the company’s production needs while improving energy utilization.

Furthermore, the boiler’s three-pass water-fire tube design enhances structural integrity, preventing thermal stress and extending service life. For industries like plastics manufacturing, where uninterrupted operation is essential, these design features translate into stable output and reduced downtime. The project demonstrated how ZOZEN’s engineering capabilities can align product design with real production requirements, ensuring that performance and cost efficiency go hand in hand.
