The NO x emissions were found to increase with the higher excess air ratios; the NO x values in the flue gas (at 6% O 2) ranged from 257 to 325 ppm, whilst the excess air ratio varied from 1.06 to 1.32 at the economizer outlet. Owing to the highly-efficient operation of the flue gas desulfurization units, the SO 2 emissions from the unit were
Commercial Boiler Stack Economizer | HVAC Heating - Caution. It is not advisable to try this at home. When you cool the combustion gasses it causes the moisture in the gasses to condense. This condensation is highly caustic and will cause severe problems with your boiler or furnace venting system.
boiler to the boiler room will normally run 1.4% to 1.6%. These same losses on a Clayton Steam generator, with much lower surface area, will run less than 0.75%. A Clayton Steam generator is also highly efficient in it’s use of space. Space is at a premium in most installations: either for existing or new construction. Clayton
Savings Test) utilizes key operating metrics from your current boiler system to determine how efficient your boiler room is in its current state.

The condensate water from the condenser is used as feed water to the boiler. Some water also could be lost in the cycle that is appropriately created up from external source. The feed water on its way to the boiler is heated by water heaters and economizer. This helps in raising the overall efficiency of the plant.
Use Feedwater Economizers for Waste Heat Recovery A feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to incoming feedwater. Boiler flue gases are often rejected to the stack at temperatures more than 100°F to 150°F higher than the temperature of the generated steam. Generally, boiler
Economizers have been used to harvest Btus that would otherwise go up the chimney, quite literally, for a long time. Waste heat recovery in a boiler as pre-warmed water, or for storage economizers, can often reduce fuel requirements by 5% to 10%, with the economizer paying for itself in less than two years.
• must be highly efficient by transferring the maximum heat available in the fuel to the water and the steam • fuel must be completely and efficiently burned • proper baffling • heating surfaces must be large enough and arranged for the maximum heat is absorbed • well insulated
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.

An indirect contact or direct contact condensing economizer will recover the residual heat from the combustion products. A series of dampers, an efficient control system, as well as a ventilator, allow all or part of the combustion products to pass through the economizer, depending on the demand for make-up water and/or process water.
Function of economiser in thermal power plant is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler. It is simply a heat ex-changer with hot flue gas on shell side and water on tube side with extended heating surface like Fins or Gills.
