Can ZOZEN design two 5 ton blast furnace gas steam boilers for low calorific value gas?

Yes. For a project requiring two 5 ton blast furnace gas steam boilers using fuel with a calorific value of about 1000 kcal, ZOZEN Boiler can evaluate the fuel composition and provide a customized steam boiler solution.

Blast furnace gas is a typical low calorific value gas. Compared with natural gas, blast furnace gas has lower heating value and usually requires a larger gas flow rate, a suitable burner system, stable combustion control and matched furnace structure. Therefore, a 5 ton blast furnace gas steam boiler cannot simply follow the standard natural gas boiler configuration. The boiler furnace volume, burner selection, gas pressure, gas supply stability and safety interlock system should be reviewed together.

For this demand, ZOZEN can consider a customized gas-fired steam boiler solution according to the actual fuel parameters. The customer needs to provide gas composition, calorific value, gas pressure, moisture content, dust content, steam pressure, steam temperature and operating load. These data are important for the design of a low calorific value gas steam boiler.

A 1000 kcal blast furnace gas boiler should pay attention to combustion stability. ZOZEN can configure a suitable combustion system and automatic control system to help maintain stable steam output. Safety devices such as flame detection, pressure protection, gas leakage protection, purge control and automatic shutdown logic should also be included in the system design.

ZOZEN Boiler manufactures industrial steam boilers for different gaseous fuels, including natural gas, biogas, coke oven gas and other process gases after technical confirmation. For two sets of 5 ton blast furnace gas steam boilers, ZOZEN can provide boiler body design, auxiliary equipment matching, control system selection and technical drawings for project review.

Before quotation, the key point is to confirm whether the blast furnace gas boiler fuel condition is stable enough for continuous steam generation. After receiving complete fuel data, ZOZEN can recommend the boiler model and system configuration.
