An 8 ton boiler is an industrial steam boiler designed to produce 8,000 kg of steam per hour (8 TPH), equivalent to approximately 5.6 MW of thermal capacity. Depending on fuel type, boiler structure, and working pressure, the reference 2026 EXW price ranges from approximately USD 48,000 to 145,000 for WNS gas/oil-fired and SZL coal/biomass-fired boilers.
An 8 ton steam boiler is commonly used as the main steam source for factories with sustained base-load demand. Compared with smaller 4–6 TPH units, its larger steam output provides more reserve for simultaneous production lines and helps reduce frequent load cycling during normal operation. In multi-boiler plants, an 8 TPH unit can carry the base load while smaller boilers handle peak demand or standby duty, improving operating flexibility and steam supply reliability.

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 EXW price of an 8 ton steam boiler is about USD 48,000 – 72,000 for a WNS gas/oil fired boiler and USD 88,000 – 145,000 for an SZL coal/biomass fired boiler.
The final price depends on working pressure, fuel system, burner selection, auxiliary equipment, and project requirements.
With natural gas LHV of about 8,500 kcal/Nm³, a WNS 8 ton steam boiler usually consumes around 580–620 Nm³/h at full load.
With an integrated condensing economizer, consumption can be reduced to about 520–540 Nm³/h depending on operating conditions.
An 8 ton (8 TPH) steam boiler has a rated steam capacity of 8 tons per hour.
Yongxing supplies WNS gas/oil fired and SZL coal/biomass fired steam boilers for industries such as food processing, textile, chemical, pharmaceutical, and paper production.
WNS boilers are suitable for customers using gas or oil who need high automation and easy installation.
SZL boilers are suitable where coal or biomass fuel is available and lower fuel costs are a priority. Selection depends on fuel type, working pressure, and steam demand.
An 8 ton (8 TPH) steam boiler is widely used in food processing, textile, chemical, pharmaceutical, paper, rubber, wood processing, and building material industries.
It provides stable steam supply for medium-to-large industrial production.
WNS boilers are available with working pressures of 0.7, 1.0, 1.25, 1.6, and 2.5 MPa. SZL boilers are commonly available with 1.25 MPa and 2.5 MPa pressure options.
The pressure should be selected according to the production process, steam transmission distance, and temperature requirements.
The thermal efficiency of a WNS condensing gas/oil fired steam boiler can reach up to 100.9% based on LHV calculation.
The thermal efficiency of an SZL coal/biomass fired steam boiler is generally around 80%–88%, depending on fuel quality, load, and system configuration.
The boiler room should have sufficient foundation capacity, ventilation, and space for installation, maintenance, and lifting operations.The specific requirements depend on the boiler model, auxiliary equipment, and local regulations.
WNS boilers are delivered as complete packaged units for easier installation, while SZL boilers are transported in modules and assembled on site.
Dimensions and transport weight vary by model and configuration. GA drawings, foundation drawings, and transport documents are available after project confirmation.
WNS boilers usually include a burner, feed water pump, water treatment system, PLC control system, and optional condensing economizer.
SZL boilers require fuel feeding, fans, economizer, ash removal, dust removal, and water supply systems according to fuel type and local requirements.
Standard 8 ton steam boilers usually require 35–50 days for production.Customized projects or systems with more auxiliary equipment may require 60–90 days, depending on the configuration.
With proper water treatment, correct operation, and regular maintenance, an 8 ton steam boiler can typically operate for more than 20 years.
