ASME Standard Energy Saving Horizontal Boiler Air Preheater for Industry
Product Introduction
Air pre-heater is a kind of equipment used to improve the heat exchange performance of the boiler and reduce energy consumption. Air preheater is generally divided into three types: plate type, rotary type and tube type. Taking the rotary type as an example, the working principle of air preheater is introduced. A large number of unburned combustibles will deposit on the heat transfer elements, which may cause the air preheater to ignite. The reasons for the ignition and the countermeasures are described in detail. The analysis of the switch-off and the treatment of air leakage are also introduced in detail.

Features
- An air preheater (APH) is a general term 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.
- In particular, this article describes the combustion air preheaters used in large boilers found in thermal power stations producing electric power from e.g. fossil fuels, biomasses or waste.
Advantages
The recovery of waste heat from the flue gas and heating the air required for Boiler In an air heater gives the following advantages.
- The Boiler efficiency is increased.
- More stable combustion in furnace.
- The combustion is intensified with the use of hot air.
- The combustion is made complete with negligible amount of carbon in ash.
- Lower grades of coals can be burnt efficiently with hot-air.
- The use of hot air, improves the heat transfer rate and so less heat transfer area will be required
- Faster load variations are possible.
- The coal can be dried effectively for easy pulverization and combustion.
