  • Cold End Corrosion in a Boiler and Its Prevention

    Condensation of these acids results in metal wastage and boiler tube failure, air preheater corrosion, and flue gas duct corrosion. In order to avoid or reduce the cold end corrosion the gas temperature leaving the heat transfer surface in boiler is kept around 150 degrees centigrade, ranging from 120 to 155. It is very important that the metalLearn More

  • Why Economizer and Air Pre-Heaters are Provided in Boilers

    The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat loss in the flue gas. As a consequence, the flue gases are also conveyed to the flue gas stack (or chimney) at a lower temperature, allowing simplified design of the conveyance system and the flue gas stack.Learn More

  • A Study on Experimental And CFD Simulation of Performance

    Abstract- The poor performance of an air preheater in the modern power plants is one of the main reasons for higher unit heat rate & is responsible for deterioration in boiler efficiency. The main problem of air preheater is the leakage of air to the flue gas side & thereby resulting in poor thermal performance.Learn More

  • Combustion air preheating for refinery heaters using plate

    In boiler operation, heat loss to flue gases amounts to as much as 20 to 25% of the heat input. To recover heat from flue gases, economizers are generally used to preheat boiler make-up water or forced draft combustion air. The dew point usually limits the practical lower temperature of the flue gas …Learn More
