A 3 ton gas steam boiler uses natural gas or liquefied petroleum gas (LPG) as fuel, converting the chemical energy of gas into heat energy to produce steam. This equipment generates 3 tons of saturated steam per hour and is widely used in industries such as food processing, pharmaceuticals, textiles, paper manufacturing, and chemical production. Compared with coal or biomass boilers, gas-fired boilers have the advantages of high efficiency, clean combustion, and simple operation.
The price range of a 3 ton gas steam boiler varies depending on the design, control system, and auxiliary equipment. Generally, a small vertical gas boiler costs around $7,000–$12,000, while a large horizontal automatic gas boiler can reach $18,000–$35,000. High-efficiency condensing gas boilers, which feature energy recovery systems, may cost even more due to advanced technology and emission control components.
Structure: Horizontal gas boilers are more expensive than vertical models because they have a larger heat exchange area, higher efficiency, and more complex design.
Steam pressure: The higher the working pressure, the more demanding the material and manufacturing requirements. For example, a 1.6MPa boiler costs significantly more than a 1.0MPa boiler.
Manual Control: Cheaper, suitable for users with low automation needs.
Automatic Control: Slightly more expensive but much safer and easier to operate. PLC-based automatic control systems improve combustion efficiency and reduce gas waste.
Equipping the boiler with low-NOx burners and flue gas recirculation (FGR) systems helps reduce nitrogen oxide emissions and meet environmental standards, but increases the cost by about 10–15%.
Including auxiliary devices such as burners, water treatment systems, and economizers increases the total investment but improves operational stability and efficiency.
A 3 ton gas steam boiler consumes about 210–250 m³ of natural gas per hour depending on the efficiency (90–95%). The current natural gas price ranges between $0.4–$0.6/m³.
| Item | Consumption / Hour | Unit Price | Cost / Hour |
|---|---|---|---|
| Natural Gas | 210–250 m³ | $0.4–$0.6 / m³ | $84–$150 |
| Electricity | 25–35 kWh | $0.09 / kWh | $2.2–$3.1 |
| Labor & Maintenance | — | — | $1.5–$3.0 |
| Total Operating Cost | $90–$155 / hour | ||
Let’s take a $20,000 gas steam boiler as an example. If the cost of each ton of steam is $40 and the selling price is $60, the profit per ton is $20. A 3 ton boiler produces 3 tons of steam per hour, generating a profit of $60/hour. Assuming it operates for 20 hours per day and 300 days per year, the annual profit reaches $360,000, meaning the payback period is less than one year.
It produces 3 tons of saturated steam per hour, suitable for medium and large industrial applications.
A well-maintained 3 ton gas steam boiler can operate for 15–20 years. Regular water treatment and maintenance can significantly extend its lifespan.
Gas boilers have higher efficiency, lower emissions, and require less maintenance. They are also easier to operate and meet strict environmental standards in most industrial regions.
The cost of a 3 ton gas steam boiler depends on factors such as structure, control system, and environmental configuration. Although the initial investment is higher than that of coal or biomass boilers, its high efficiency, clean combustion, and low operating cost make it a preferred choice for modern industrial steam supply. Choosing the right model based on production needs can achieve both economic and environmental benefits.
