What are the specifications of ZOZEN's 12 MW dual-fuel (gas + diesel) boiler?

ZOZEN offers dual-fuel boiler solutions that support natural gas as the primary fuel and diesel (light oil) as a backup or switchable alternative. This configuration is widely used in industrial facilities where fuel supply reliability is a priority, or where diesel is used during gas supply interruptions.

For a 12 MW output, the SZS series water-tube boiler covers this capacity range with the following parameters:

Capacity: up to 14,000 kW (14 MW)
Working pressure: 1.25–2.5 MPa
Thermal efficiency: ≥92%
Fuel: natural gas / LPG / diesel / light oil (dual-fuel burner)
Burner switching: automatic switchover between gas and diesel modes
Control system: fully automatic PLC operation with multi-point safety protection
Emissions: NOx output as low as 30 mg/Nm³ with low-NOx burner option
Alternatively, for hot water output at 12 MW, the YQW series horizontal thermal oil boiler or a hot water variant of the SZS can be configured depending on the application — whether for process heating, district heating, or industrial steam supply.

The complete package includes the boiler body, dual-fuel burner, economizer, control cabinet, water treatment system, and auxiliary piping. ZOZEN can also provide an EPC (Engineering, Procurement, and Construction) solution if a turnkey installation is required.
