Study on performance and methods to optimize thermal oil

economizer preheats the feed water, using the waste heat in the exhaust fuel gas [10-11]. This paper focuses on the thermal oil boiler performance in the Mazandaran cement plant. It also presents and describes useful methods (excess air control and use of economizer) for increasing boiler efficiency and energy savings. Abbreviations

Wilfrid Francis, Martin C. Peters, in Fuels and Fuel Technology (Second Edition), 1980. 2 Dust-laden Gases (0.002 to 0.03 g m −3) (a) High Concentration—Dry Dust, e.g. Cement Kilns With such gases, water-tube boiler techniques are applied, using two or three drums, superheater and economizer. The gases are often arranged to flow horizontally across banks of vertical water tubes.

Finding the Root Cause of Boiler Tube Failures

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water

Air preheater - Wikipedia

Types. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation.

BOILER ECONOMISER - Thermal Power Tech

In a boiler system, an economizer captures the heat of the flue gas and transfers it to the feed water. The process is simple. As the flue gas exits the boiler, it enters an economizer with finned tubes. The finned tubes absorb the heat and raises the temperature of the boiler …
