Project Background
Green hydrogen production by water electrolysis depends on reliable high-temperature and high-current electrical equipment. Shaanxi Chengda Industrial Furnace Manufacturing Co., Ltd. has extended its metallurgical electric furnace engineering capability into the new energy sector, supplying electric heating and power equipment for water electrolysis hydrogen projects in Sichuan, Guangdong and Hebei provinces.
Project Portfolio
| Location | Application | Scope |
|---|---|---|
| Sichuan Province | Water electrolysis hydrogen production | Electric heating and power supply equipment |
| Guangdong Province | Water electrolysis hydrogen production | Electric heating and power supply equipment |
| Hebei Province | Water electrolysis hydrogen production | Electric heating and power supply equipment |
What Chengda Contributes
- High-current electrical design - decades of short network, busbar and transformer experience transferred from submerged arc furnace engineering to electrolysis power systems.
- Thermal management - cooling circuit design and water quality control proven in furnace water-cooled components.
- Automation and safety interlocking - PLC based control with temperature, pressure and conductivity interlocks for safe unattended operation.
- Turnkey delivery - design, fabrication, installation supervision and commissioning by a single supplier.
Why a Furnace Maker Builds Hydrogen Equipment
Electric furnaces and electrolysers share the same engineering fundamentals: large direct current, water cooling, thermal stress, and strict safety requirements. Chengda's design team applies the same FEA-based thermal and structural analysis, the same water pressure testing regime and the same quality documentation to hydrogen equipment as to a 33,000kVA ferronickel furnace.
Outcome
All three provincial projects were delivered with complete electrical drawings, commissioning records and operator training. The projects position Chengda as a thermal and electrical equipment partner for the energy transition, not only for traditional metallurgy.
Scope of Delivery
Each project included equipment design, fabrication, factory testing, delivery to site, installation supervision, commissioning and operator training, with complete electrical drawings and safety interlock documentation handed over at the end of the project.
Engineering Interface with the Electrolyser
The equipment had to interface with the customer's electrolyser stacks, DC bus and plant control system. Chengda issued interface drawings early, agreed signal lists with the EPC contractor, and verified power quality limits before shipment. On site, commissioning covered current ramp tests, cooling loop verification, interlock simulation and full load trials in coordination with the hydrogen production schedule.
Chengda's electrode and busbar experience also helps customers specify rectifier, cable and cooling capacities correctly at the design stage, avoiding costly oversizing or under-rated hardware once the plant moves from pilot to commercial hydrogen output.
All three provincial projects were delivered on schedule and are now part of Chengda's growing reference list in the hydrogen equipment market.
