Anti - Wear Customized Preheater In Boiler For Power Station And Industry

Customized Stainless Steel Boiler Air Preheater for Power Station and Industry

Detailed Porduct Description

Product Introduction

• 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.

1. The Boiler efficiency is increased.
2.  More stable combustion in furnace.
3. The combustion is intensified with the use of hot air.
4. Lower grades of coals can be burnt efficiently with hot-air.
5. The use of hot air, improves the heat transfer rate and so less heat transfer area will be required.
6. The combustion is made complete with negligible amount of carbon in ash.
7. Faster load variations are possible.
8. The coal can be dried effectively for easy pulverization and combustion.
