What is Air Preheaters

A very basic word to word meaning is a device used to heat the air before further use is called as Air Preheater. They are also recognized as air heaters or air-heating pipe. It is designed to exchange heat energy with desuperheaters. Desuperheater is a Device which is been used to reduce the temperature of the steam in a high heat generation plants where large amount of heat energy or steam is released in the atmosphere.<br><br>

  1. What is Air Preheaters

  2. Index • Why is hot air sent to the furnace? • Type of Air Preheaters (APH) • Working of Air Preheaters(APH) • Air Preheater Pros:

  3. Air Preheaters (APH) is that the Shell and tube sort Heat Exchangers used for preheating the air that is fed to the boiler or furnaces/kilns for combustion of fuels. • Its primary objective is to extract the waste heat from the flue gases deed the boiler. • ThermodyneEngineering Systems manufacture Air Preheaters and ar given as a customary aspect accenttogether with the most instrumentation – Boiler, in a very prepackaged sort Boiler, Combi Boilers.

  4. Why is hot air sent to the furnace?For generating hearth in a very boiler chamber three main ingredients ar needed: Fuel, Air & Ignition. Air is employed in a very Boiler for combustion of fuel. supported the ratio calculation, the correct amount of air together with excess air is fed into the boiler chamber for the combustion of fuel.

  5. Generally, fuel fed to the boiler is at traditional temperature and for combustion of fuel to require place; the temperature of the fuel is exaggeratedfrom its temperature to ignition temperature. therefore to extend the potency of the combustion methodadditionally as a boiler, hot air is fed to the chamber for the combustion of fuel.

  6. Type of Air Preheaters (APH)We manufacture completely different sort of air preheaters:-• Shell and tube sort single pass air pre-heaters• Shell and tube sort dual-pass air pre-heaters• Finned tube air pre-heaters

  7. Working of Air Preheaters(APH) • Air Preheaters have a shell and tube sort construction wherever exhaust heat from the flue gases is transferred to the air after they are available in indirect contact with one another.Air Preheaters encompass a shell wherever tubes ar organized in a very sq. or triangular pitch and ar welded to a tube plate. relying upon the sort of operation and simple improvement, flue gases & air is allowed to travel either shell aspect or tube aspect interchangeably.

  8. http://www.maniks.com/manufacturer/air-preheater/ • Also Read: what's Combi Boiler?Thermodyne Boilers finned tube air preheaters ar designed to maximise the potency by increasing the heating area while not increasing the area demand.Thermodyne Engineering Systems manufacture air preheaters that ar custom to suit the customer’s demand. Our Air Preheaters ar designed in each one and a couple of pass for each flue gases and air to extract most heat from the flue gases.

  9. Thermodyne Boilers manufacture air pre-heaters for wide capability vary and may satisfy the varied fuel needs of a client such as:• Wood• Coal• Husk• Bagasse• Petcoke• Light Oil and significant Oil

  10. Air Preheater Pros:• 2 pass style to extract most waste heat from flue gases deed the boiler.• It is employed to extract waste heat from the flue gases deed the boiler exhaust thereby increasing the potencyof a boiler by 2-3 nada.• It is employed to heat the fuel that more will increase the boiler potency.• Payback time is a smaller amount.
