An air preheater (APH) is any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process.They may be used alone or to replace a recuperative heat system or to replace a steam coil.. In particular, this article describes the combustion air preheaters used in large boilers found in
Abstract. The paper presents analysis of data obtained from tests of oil shale (OS) and peat co-combustion in a full-scale 250 M[W.sub.th] (useful heat output) circulating fluidized bed (CFB) boiler. The tests were conducted at nominal boiler load, with peat thermal input up to 30%.

Influence of Coal Quality and Boiler Operating Conditions . 2019-2-18 · Influence of Coal Quality and Boiler Operating Conditions on Slagging of Utility Boilers by Rod Hatt Coal Combustion, Inc. Versailles, KY 859-873-0188 Introduction Ash deposits formed from the combustion of coal and other fuels have plagued the steam p roduction industry from the start.
Heng Chen To understand deposit formation in the flue gas cooler, which is used to recover the exhaust heat from a 300 MW coal-fired boiler in China, a mineralogical study was carried out.
‘Boiler feed water pump’ pumps the water at high pressure into the boiler from the ‘feed water tank’. The pump is akin to the heart in the human body. Pre-Heating ‘Feed water heaters’, using extracted steam from the turbine, adds a part of the sensible heat even before the water enters the boiler.
The gross power output of a 642.18-MW, turbine cycle heat rate (HRcycle) of 7,467 Btu/kWh (ηcycle,gross = 45.69%), APH leakage of 10%, flue gas temperature at the boiler outlet of 680F, and coal

Recuperative and regenerative air pre-heaters are vulnerable for plugging under certain specific conditions of operation of boiler. A few of these conditions are design related and the others are operation oriented. Air pre-heater being the last heat transfer surface in the boiler it is subjected to the lowest temperature in boiler operation.
The main purpose of boilers is to produce a good reservoir of heat energy through steam under pressure that can be readily converted into work inside heat Engines. Other uses include using the steam reservoir for heating and drying purposes at hom
