Economizer is a heat exchanger device that captures the "lost or waste heat" from the boiler's hot stack gas. The latest technology boiler spiral finned tubes economizer typically transfers this waste heat to the boiler's feed-water or return water circuit, but it can also be used to heat domestic water or other process fluids
Our enconomizer is squeezing by high frequency welding method and the technology of steel strip according to certain structure automatically, continuous spiral welding outside the light tube wall, and then the other reserved part light tube bending, combination according to the requirement. As a result, the diameter and length under the same conditions, it has larger heat transfer area.

ASME Standard Surround Gasket,
An air preheater (APH) is a general term used to describe any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil. Normal air preheater exist the problem of collection of ash,worn down,low temperature corrosion to effect the safe and economical operation for the boiler unit. So HTEG established the exclusive enamel research and development center to supply the complete solution and organize the scientific reserach personnel to tacle key problems and develop the new heat transfer parts-enameld tubes air preheater We have achieved ISO standard certificates as below: 1) Certificate of conformity of quality management system certification . 2) Environmental management system certificate 3) Occupational health and safety management system certificate 4)Installation, Alteration, Repair & Maintenance License of Special Equipment People's Republic of China Clients Visiting We have been reliable and steady supplier many domestic and overseas clients. We have exported products of economizer, membrane water wall, gas fired boiler etc to vietnam, mongolia, parkistan, indonesia these years and won great appraisal from clients for good price and finest quality.
