The patent was achieved in 1930. Even in a modern utility boiler the preheater provides up to 20 percent of the total heat transfer in the boiler process, but only represents two percent of the investment.

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 Ljungstrom three sector air preheater. have modeled complete rotary air pre heater including support and guide bearing assembly.

The sector-shaped thing on the front of the smokebox is the drive to the friction rollers that rotated the preheater.
The Ljungström Air Preheater is a regenerative heat exchanger, and comprises a slowly rotating rotor filled with heat transfer plates. The hot and cold gas ducts are arranged so that half of the rotor is in the flue gas duct and the other half is in the primary air duct which supplies combustion air to the furnace. LJUNGSTRÖM combines the resources of the leading names in our industry, including SRM, Air Preheater Company, Kraftanlagen, Gadellius, Stein, PBS, and APEL. Our proven performance, reliability and commitment to ongoing innovation have enabled us to maintain our reputation as the industry experts in air preheater and gas-gas technology. The Ljungstrm Air Preheater 100.4 m 90.9 m General Basically, the Ljungstrm APH is a regenerative heat exchanger through which flue gas and combustion air pass in a counter-current flow. The waste heat of the flue gas is thus recovered and used for heating the combustion air. Fredrik Ljungström's technology of the air preheater is implemented in a vast number of modern power stations around the world until this day, with total attributed worldwide fuel savings estimated at 4,960,000,000 tons of oil, "few inventions have been as successful in saving fuel as the Ljungström Air Preheater".
