The Boiler Parts Enamel Coated Air Preheater is a heat recovery component designed for industrial boilers, featuring a ceramic enamel coating applied to carbon steel or low-alloy steel surfaces to resist corrosion and thermal degradation. The unit operates by preheating combustion air using waste flue gas, typically achieving temperature rises of 150°C to 250°C depending on boiler load and gas flow. Exact dimensions and tube spacing are customisable based on boiler model, with standard tube diameters ranging from 25mm to 50mm and wall thicknesses between 1.5mm and 3.0mm as per source data.
The enamel coating is applied in a single-layer or dual-layer process, with typical thicknesses of 120 to 200 micrometres, conforming to standard industrial enamel specifications for high-temperature resistance up to 450°C. The substrate material is usually ASTM A285 Grade C or equivalent, selected for its thermal expansion compatibility with the enamel layer. Unlike painted or galvanized alternatives, this coating resists flaking under cyclic thermal stress and maintains surface smoothness to reduce soot accumulation, a key factor in long-term efficiency.
This component is primarily purchased by power plant operators, cement kiln managers, and chemical process engineers seeking to reduce fuel consumption by 5% to 12% through improved combustion efficiency. Buyers typically require custom configurations to match existing boiler flue gas ducts and air intake systems. Trade terms include FOB Qingdao or CIF destination ports, with packaging in wooden crates for bulk shipment. Lead time is generally 4 to 8 weeks after order confirmation, subject to production scheduling.

Before ordering, verify the exact material grade of the steel substrate and the enamel formulation, especially if operating in high-sulfur or high-chlorine environments. Request test reports for coating adhesion, thickness uniformity, and thermal shock resistance. Do not accept generic claims without batch-specific documentation. Confirm that the supplier’s production process aligns with ASME or EN standards for pressure-containing components where applicable.
Logistics are typically handled via FOB Qingdao or CIF destination port. Lead time ranges from 4 to 8 weeks depending on order volume and production queue. Incoterms must be clearly defined in writing, as CIF may include unverified insurance coverage. Payment terms are commonly 30% advance, 70% against shipping documents. Request a packing list and container loading photos prior to final payment.
Quality inspection should include visual checks for enamel cracks, pinholes, or blisters, especially at weld joints. Use a high-voltage holiday detector to identify coating defects. Require a material certification for the steel and a coating thickness report per ISO 2808. Retain samples for third-party lab testing if operating under strict regulatory frameworks. Documentation must include traceability to the production batch number.
