Product Name: Recuperators for Reduction of Heat Losses and Fuel Savings
Product Description
Air Preheating - General
In modern industrial furnaces and many chemical processes, the exhaust gases
leave the working area at very high temperatures. This leads to a high heat
loss. If the heat of the exhaust gases is utilized, considerable savings of
fuel are possible. This is very easily achieved by means of recuperators, i.e.
heat exchangers where the combustion air is preheated by means of the hot
exhaust gases and thus a part of the otherwise lost heat is fed back to the
furnace or process. If fuels with a low calorific value are used, the required
process temperatures can often only be reached, if the air or the heating gas
is preheated. In this case, the use of a recuperator is absolutely necessary,
irrespective of considerations in terms of savings.
Convection Recuperators
These units have been developed for the heat utilization of heavily dust-laden
flue or process gases with temperatures of up to 1100 :C. The combustion air
can be preheated up to 900 :C. Cleaning is possible by means of steel shot
cleaning units or steam jet systems. The supporting tube plate must often be
constructed as a cooled double bottom when the inlet temperatures of the heat
transferring gas are high and heating temperatures are at the same time also
elevated. This type of recuperator is mainly used for metal smelting furnaces,
such as for example in the aluminium industry, in smelting furnaces of the
ceramic industry, in chemical and petrochemical processes and in fluidized bed
furnaces for the
