Import 2t Steam Boiler For Integrated Rice Mill China — Buy in wholesale FOB from Supplier in China

The WNS series 2 tonne per hour steam boiler from Henan Yuanda Boiler Corporation Ltd. is a horizontal three-pass fire tube wet back design, factory-configured for integration into rice milling operations where steam is required for parboiling, drying and humidification. The unit accepts natural gas, LPG, LNG, CNG, city gas, biogas, diesel oil or heavy oil through a common burner platform. Design pressure options span 1.0 MPa, 1.25 MPa, 1.6 MPa and 2.5 MPa, with corresponding saturated steam temperatures up to 224 degrees Celsius. The fully automatic control package handles combustion sequencing, feed water regulation and safety interlocks without permanent operator attendance.

The three-pass configuration routes combustion gases through a corrugated furnace tube, a reversal chamber and then two sets of smoke tubes before exiting to the stack, maximising heat transfer surface exposure and thermal efficiency. Wet back construction places the reversal chamber within the water space, eliminating the refractory maintenance associated with dry back designs and improving thermal cycling resistance. The boiler shell is carbon steel with standard thickness per Chinese GB or ASME code depending on the export destination. Fire tube boilers in this capacity range typically achieve 92-95 percent thermal efficiency on gas firing with economiser fitted. The full automatic control system includes PLC-based burner management, feed water pump control and low-water cut-off protection.

Integrated rice mills consume steam at 0.5-1.0 MPa for parboiling paddy and at lower pressures for drying and process heating. A 2 t/h boiler suits small to medium mills processing 2-4 tonnes of paddy per hour, depending on the parboiling method and steam demand profile. Buyers should confirm whether the quoted boiler includes a feed water tank, water treatment plant, chimney stack and fuel train, or if these are priced separately. Standard export practice for Chinese boilers is FOB Shanghai or Tianjin with crated or naked shipment on flat rack. Payment terms are typically T/T or L/C. Installation supervision and commissioning by Yuanda engineers can be negotiated as an additional service.

Henan Yuanda Boiler Corporation Ltd. is located at Qihang Building on Shanghai Eastern Road in Zhengzhou, Henan Province, a central China industrial hub with established boiler and pressure vessel manufacturing history. The supplier holds a harbour trust tier on the platform. The response rate is recorded at 0.00 percent with zero average response hours, so direct communication through the enquiry channel or alternative contact methods is essential to establish current product availability and technical support capability. No verified factory audit, ASME certificate or specific quality accreditation numbers appear in the listing data.

The supplier profile does not state year of incorporation, annual production capacity, number of employees, domestic market share or reference installations in specific rice milling countries. Buyers should request a current special equipment manufacturing licence, pressure vessel design approval and any ISO 9001 or ASME U/S stamp certificates applicable to the WNS series. Confirm whether Henan Yuanda operates its own foundry and tube fabrication facilities or sources pressure parts from subcontractors, as this affects quality traceability.
