A 1 ton boiler is a compact industrial steam boiler designed to produce 1,000 kg of steam per hour (1 TPH), equivalent to approximately 0.7 MW of thermal capacity. Depending on fuel type and boiler design, the reference 2026 EXW price ranges from approximately USD 8,000 to 23,000 for WNS gas/oil-fired, DZL coal/biomass-fired, and DZH coal/biomass-fired models.
A 1 ton steam boiler is typically suitable for small factories and production lines with relatively low or fluctuating steam demand. Its compact size and lower water volume allow faster steam generation and quicker response to load changes, with packaged gas/oil-fired models typically producing steam within 10–20 minutes from a cold start. Multiple units can also operate in parallel for flexible capacity and future production expansion.

Note: 1、All projections are theoretical estimates assuming constant fuel prices. Fuel calorific values and efficiencies are expressed on an LHV basis (Natural Gas: 8,500 kcal/m³ | Biomass: 4,000 kcal/kg | Bituminous Coal: 5,000 kcal/kg). 2、Thermal efficiencies are standardized baseline values for comparison only; actual performance varies with fuel quality, moisture content, and operating conditions. 3、For condensing natural gas boilers, efficiencies above 100% reflect LHV-based latent heat recovery. 4、Extra operating costs such as electricity, water, labor, and maintenance are excluded. 5、Intermediate calculations use full precision; displayed figures are rounded. |

the reference 2026 EXW price of a 1 ton steam boiler:
1 ton gas/oil fired steam boiler (WNS): USD 8,000 – 14,000
1 ton coal/biomass fired steam boiler (DZL): USD 13,000 – 23,000
1 ton coal/biomass fired steam boiler (DZH): USD 8,500 – 16,000
The final price depends on working pressure, fuel system, burner selection, auxiliary equipment, and project requirements.
Standard non-condensing gas models (88%–92% efficiency) consume approximately 75–80 Nm³/h of natural gas at full load.
With a flue gas condensing recovery system, thermal efficiency can reach up to 100.9% based on LHV calculation, lowering gas consumption to around 70–72 Nm³/h.
A rated capacity of 1 t/h steam output is equivalent to approximately 0.7 MW, 700 kW, 600,000 kcal/h, or about 64–71 Boiler Horsepower (BHP), depending on the conversion standard.
Regular bottom blowdown removes sludge and dissolved solids from the boiler water.It helps control TDS levels, reduce scale formation, and prevent steam carryover. The blowdown frequency should be adjusted according to water quality conditions.
Due to its compact water volume and high heat transfer intensity, a 1 ton boiler requires careful water quality control.Scale deposits reduce heat transfer efficiency and increase the risk of overheating, while ash accumulation can reduce draft and heat transfer if not removed regularly.
Gas-fired boilers typically require inspection every 6 months, or more frequently under heavy cycling conditions.
Biomass boilers require regular ash removal and tube cleaning, while oil-fired boilers need periodic soot cleaning. The maintenance interval depends on fuel quality and operating conditions.
A 1 ton boiler is suitable for small food processing plants, laundries, pilot production lines, laboratories, and chemical facilities with stable steam demand and limited installation space.For large load fluctuations, a steam accumulator can help improve system stability.
A standard package includes the boiler body, burner, control panel, water treatment equipment, feedwater pumps, economizer or condenser, valves, instrumentation, and safety protection devices.
Additional equipment, such as steam headers and auxiliary systems, can be configured according to project requirements.
A packaged 1 ton boiler mainly requires connections for feedwater, electrical power, fuel supply, steam outlet, and flue gas systems before commissioning.
The three-pass design extends the flue gas path to improve heat transfer.The wet-back chamber uses water cooling instead of rear refractory bricks, reducing refractory maintenance and improving long-term operating reliability.
