    The proper resolution for this situation is an air heater rather than such tactics as nailing a 4 ft x 8 ft sheet of plywood over the louver assembly, as seen on several occasions. Fouling (sooting) of the flue-gas side of the boiler is the least one can expect from this type of action. Maintenance and HousekeepingLearn More

  • Role of Primary Air Fan and Secondary Air Fan in Thermal

    Steam boilers having an external furnace are generally provided with both Primary ( pa fans ) and Secondary air inlets and both play an important role in the combustion of fuel. Primary air is generally the basic amount of air required for complete combustion of fuel and it depends upon the composition and quantity of fuel required by the boiler.Learn More

  • Inside Power Station: Gas Air Heater

    The heating chamber consists of a fluidized bed of coke wherein air is supplied from bottom. The heat generated by combustion of coke and air is used to heat water to form steam. The steam generated is used in various processes across the unit. The boiler operates for an average of 12 hours daily.Learn More

  • A dictionary of heating boiler parts with links to

    STEAM HEATING BOILERS produce steam to distribute heat through one pipe or two pipe steam heat systems and steam heat radiators. Some heating systems use a hydronic boiler to heat water that is circulated thorough a heating coil inserted in the plenum of a WARM AIR FURNACE heating system, using a water-to-air heating method.Learn More

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

    May 03, 2009 · Boilers are provided with economizer and air pre-heaters to recover heat from the flue gases. Boilers operate with around 86 to 90% efficiency depending upon the type of fuel and design adopted. A degrease of about 20 % of boiler efficiency is seen by not providing both economizer and air pre-heaters. If economizer alone is provided then the efficiency will be lower by 12 % when compared …Learn More
