We are Manufacturer, Supplier of Air Preheaters (APH), Boilers, Package Type Boilers, Combi Boilers and our set up is situated in Pune, Maharashtra, India.
▸Air Preheaters (APH)
≑Air Preheaters (APH) is the Shell and tube type Heat Exchangers used for preheating the air which 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 leaving the boiler.
≑Swami enterprises and are given as a standard side accessory along with the main equipment – Boiler, in a Packaged Type Boiler, Combi Boilers.
▸Why is hot air sent to the furnace?
≑For generating fire in a boiler furnace 3 main ingredients are needed: Fuel, Air & Ignition. Air is used in a Boiler for combustion of fuel. Based on the stoichiometry calculation, the right quantity of air along with excess air is fed into the boiler furnace for the combustion of fuel.
≑Generally, fuel fed to the boiler is at normal room temperature and for combustion of fuel to take place; the temperature of the fuel is increased from its room temperature to ignition temperature. So to increase the efficiency of the combustion process as well as a boiler, hot air is fed to the furnace for the combustion of fuel.
We manufacture different type of air preheaters:
▸Working of Air Preheaters(APH)
≑Air Preheaters have a shell and tube type construction where exhaust heat from the flue gases is transferred to the air when they come in indirect contact with each other.
≑Air Preheaters consist of a shell where tubes are arranged in a square or triangular pitch and are welded to a tube plate. Depending upon the type of operation and ease of cleaning, flue gases & air can be allowed to travel either shell side or tube side interchangeably.
