Air Preheaters (APH)
An air preheater (APH) is a device used to heat air, commonly used in industrial boilers, thermal power plants, and other thermal energy facilities. APH improves the thermal efficiency of the boiler by transferring heat from the flue gas to the air entering the boiler through heat exchange with it.
APH usually consists of a Heat Exchanger with a number of parallel pipes inside the exchanger through which smoke and air flow to allow heat exchange. In APH, the smoke flows on the outside of the heat exchanger and the air flows on the inside so that the heat between the smoke and the air can be transferred through the pipe walls.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
