Fuel can be saved by 11-12%. 4,Hot air can be used as fuel disiccant. Types of Air-preheater and their Advantages and Feb 09, 2018 · today we discussed about a very important topic related to boiler combustion process helping which is air preheaters in this article we discussed about Types of Air-preheater and their Advantages and Disadvantages .Air preheater is a device which is used for the preheating the combustion air supplied to boiler for combustion by F.D ( forced draft ) fan and also sustain the temperature of burning fuel it is essential to supply combination air preheated

US3835650A - Steam air preheater for a steam boiler system

A steam boiler system includes a steam air preheater disposed in inlet ducting for preheating intake air. A boiler feed pump provides high-pressure water to a boiler which in turn produces steam to What Is Boiler Mounting? What Are Boiler Accessories 5. Air Preheater. The air preheater is used to recover heat from the exhaust flue gases. It is established between the chimney and the economist. Through the preheater, air passes for combustion purposes. This increases the temperature of the combustion air with the help of exhaust flue gases. What Is The Advantages Of Air Preheater? - News 1. 5 degree in air preheater, exhaust temperature can reduce 1 degree. After installation of air preheater in boiler flue, if we can put the air heat 150-160 degree, can reduce exhaust temperature 110-120 degree, the boiler thermal efficiency can be increased by 7% - 7.5%.Can save fuel between 11% and 12%. 4. Hot air can be used as a fuel desiccant


Abstract:Air pre-heater is a heat transfer surface in which air temperature is raised by transferring heat from other media such as flue gas .Hot air is necessary for rapid combustion in the furnace and also for drying coal in milling plants. So an essential boiler accessory which serves this purpose is air pre-heater.
