When it comes to modern industrial production, the boiler system is one of the most important components in ensuring energy efficiency, product quality, and environmental compliance. Among the many types of industrial boilers, the gas-fired boiler has become the preferred choice for various industries such as food processing, chemical production, textile manufacturing, and pharmaceuticals due to its clean combustion, stable output, and ease of operation. However, one of the most frequently asked questions by potential buyers is about the industrial gas boiler price.

In reality, the industrial gas boiler price is not a fixed figure; it fluctuates depending on multiple factors such as capacity, design pressure, material quality, automation level, brand reputation, and after-sales support. For example, the price difference between a small 1-ton gas boiler and a large 25-ton gas-fired steam boiler can be quite significant because of the difference in steel consumption, manufacturing process, and operating system.

Beyond the basic configuration, the industrial gas boiler price is also influenced by the combustion technology and the emission standards that the product meets. With global trends emphasizing green and low-carbon development, more and more customers prioritize boilers with low-NOx combustion systems, higher efficiency, and long-term stability — all of which may slightly increase the initial investment but significantly reduce operating costs over time.

Features, Parameters, and Advantages of the ZOZEN SZS Gas-Fired Boiler

When evaluating the industrial gas boiler price, it is crucial to look beyond the surface cost and understand what determines the long-term value of the equipment. ZOZEN’s SZS series fuel and gas-fired boilers are engineered with precision, combining advanced design concepts, high-quality materials, and intelligent operation systems.

ZOZEN 25 ton SZS gas-fired boiler

The SZS gas-fired boiler is designed with a double-drum, D-type structure. One side is the furnace chamber, while the other side consists of the convection heating surface. The entire body is supported by a membrane wall design, which enhances the air tightness and minimizes heat loss. This structure not only improves thermal efficiency but also ensures excellent load adaptability — a key factor for industries with fluctuating steam demands.

Typical models of the SZS series cover a wide range of evaporation capacities, from 2 to 110 tons per hour, with rated working pressures between 1.25 and 5.3 MPa. The large furnace chamber and full-membrane water wall enable complete combustion and even heat absorption. Meanwhile, the high-efficiency economizer and condenser further recover residual heat from flue gases, allowing the overall thermal efficiency to reach approximately 98% under standard conditions.

In terms of combustion system configuration, the SZS boiler adopts internationally recognized low-NOx burners, which achieve stable combustion under different loads and fuel pressures. The NOx emissions can be controlled below 30 mg/Nm³, fully complying with strict environmental protection requirements.

The control system is another important contributor to both operational safety and total cost. ZOZEN’s SZS boilers are equipped with an advanced automatic control platform that integrates water level control, steam pressure regulation, fault alarm, and safety interlock protection. Operators can easily monitor performance in real-time and adjust parameters via a touchscreen interface. This level of automation reduces human error, enhances operation reliability, and ensures consistent output quality.

When assessing the industrial gas boiler price, potential buyers should also consider material selection. ZOZEN’s boilers use high-grade steel plates, premium-quality welding consumables, and non-destructive testing methods that meet international standards such as ASME and CE. These measures guarantee structural durability and extend the service life of the boiler, effectively lowering maintenance costs over the years.

In addition, ZOZEN designs the SZS series with an emphasis on maintenance convenience. The furnace and convection sections are equipped with ample inspection holes and maintenance ports, making periodic cleaning and internal checks more efficient. This is particularly beneficial for factories that operate continuously, where downtime directly affects productivity and revenue.

ZOZEN SZS Gas Boiler Supporting the Tobacco Industry’s Energy Transition

The practical value of an industrial gas boiler extends far beyond its initial purchase price. An excellent example of this is a project completed by ZOZEN Boiler for a tobacco manufacturing plant that needed to upgrade its energy system in response to environmental regulations.

To comply with the government’s “coal-to-gas” policy and to improve its production efficiency, the tobacco plant planned to purchase a new gas-fired steam boiler that would meet both emission and efficiency standards. After a comprehensive market comparison, the company chose ZOZEN as its equipment supplier due to its reliable technical strength and reputation for quality.

ZOZEN provided a 25-ton SZS series gas-fired steam boiler for this project. The boiler’s D-type layout, consisting of a large-volume furnace and dense tube water walls, ensured full combustion and uniform heat transfer. Its narrow-pitch membrane water wall enhanced the boiler’s airtightness, reducing heat loss and improving fuel utilization.

In daily operation, the SZS boiler demonstrated stable steam generation, fast start-up, and flexible load adjustment — all crucial to the tobacco industry, where production processes such as drying and flavoring require continuous and precise steam supply. Additionally, the boiler’s NOx emissions remained below 30 mg/Nm³, effectively meeting local environmental standards.

The advanced automation and interlocking protection system also minimized operational risks. The control interface allowed operators to monitor steam parameters, feedwater conditions, and burner performance in real time. This combination of safety, efficiency, and environmental performance proved highly satisfactory for the tobacco plant, which successfully achieved energy-saving and emission-reduction goals while ensuring uninterrupted production.
