Can ZOZEN Supply Two 80 Ton Gas Steam Boilers with Dual-Fuel Systems?

An 80 ton gas steam boiler is designed for industrial projects with a large and continuous steam demand. For a tender requiring two 80 t/h units, a double-drum boiler structure and the complete auxiliary system must be evaluated together. The steam balance, operating pressure, temperature and redundancy requirements should be confirmed before a budget proposal is prepared.

ZOZEN can evaluate the SZS series for this project. The SZS series is a double-drum oil and gas boiler with a published capacity range of 2 to 110 t/h and working pressure range of 1.25 to 5.3 MPa. An 80 ton gas steam boiler therefore falls within the available capacity range of this series.

The enquiry mentions two fuels: gas and fuel gas. Before selecting the burner for each 80 ton gas steam boiler, ZOZEN engineers need the composition, calorific value, supply pressure and fluctuation range of both fuels. Industrial fuel gas can vary considerably between projects. Burner capacity, furnace dimensions, valve trains and safety interlocks must be configured according to the actual fuel data.

The proposed system can include two boiler bodies, burners, economizers, fans, feedwater pumps, deaeration equipment, water treatment equipment, control cabinets, chimneys and other related auxiliaries. The exact supply boundary should follow the tender documents. If the project requires one operating unit and one standby unit, or parallel operation of both units, the control logic and common auxiliary capacity should also be defined.

For an MED plant rated at 125 m³/h, the 80 ton gas steam boiler cannot be selected only from the water production capacity. The MED supplier should provide required steam flow, steam pressure, steam temperature, condensate return conditions and operating profile. ZOZEN can then check whether two units match the process steam requirement.

ZOZEN Boiler has over 30 years of industrial boiler manufacturing experience and more than 20 years of overseas market experience. Its production base covers 150,000 square metres, with an annual production capacity of 2,000 industrial boilers. The company can provide boiler equipment, auxiliary system design and technical coordination for international projects.

After receiving the tender document, ZOZEN can review the technical specification and prepare a budget proposal for the two-unit 80 ton gas steam boiler system.
