Import Blast Furnace Gas Fired Boiler — Buy in wholesale FOB from Supplier in China

ZG Boiler's blast furnace gas fired boiler is designed to combust blast furnace gas (BFG), a low-calorific by-product of ironmaking containing approximately 60 percent nitrogen, 18 to 20 percent carbon dioxide, 20 to 25 percent carbon monoxide, and 2 to 4 percent hydrogen, with a heating value near 93 BTU per cubic foot. The boiler employs an 'A' type arrangement with front-suspension and rear-support structure, allowing suspended superheater sections and roof-mounted pressure parts. Corner-mounted vortex burners distribute fuel and air to achieve stable ignition despite the gas's poor flammability, often supplemented by richer support fuel or preheated combustion air.

The furnace chamber is engineered as a square configuration to optimise temperature field uniformity and aerodynamic mixing, preventing localised flame impingement and promoting complete combustion of the CO-rich gas. Convection pass components including economiser and air preheater modules are arranged on rear steel shelving, with the air preheater designed for pull-out maintenance access. Multiple safety interlocks are integrated: automatic ignition sequencing, flame monitoring via UV or infrared detectors, flame failure protection, and automatic fuel shut-off on low gas pressure. Particulate removal upstream of combustion is assumed to be handled by the purchaser's gas cleaning system.

Target purchasers include integrated steel mills, captive power plants, and energy recovery projects seeking to convert waste blast furnace gas into steam for process heating or combined-cycle power generation. The unit suits environments where BFG is available in steady supply and must be flared or utilised for environmental compliance. Output capacity, steam pressure, temperature rating, and efficiency are not specified in the source data and require direct technical consultation with ZG Boiler. Incoterms, delivery scope, and installation support should also be confirmed.

ZG Boiler is headquartered in Zhengzhou, Henan Province, China (postal code 450001), a major industrial equipment manufacturing hub with rail and road connections to Qingdao, Tianjin, and Shanghai ports. The company lists a harbor trust tier but shows a zero percent response rate and zero average response hours, indicating no tracked communication through the platform. A contact name 'Tony.kangle' appears in the address field, suggesting an specific sales contact rather than a general enquiries desk.

The supplier positions itself as a designer and manufacturer of blast furnace gas fired boilers for iron and steel industry applications, with emphasis on green economy and sustainable development narratives. No information is provided about factory footprint, annual production capacity, number of installed units, ASME or CE certification status, or reference projects. Buyers should request a company brochure, quality system certificates (ISO 9001, ISO 14001), pressure equipment directives compliance, and a list of domestic or export installations with operator references before technical or commercial commitment.
