The experimental result indicates that using heat recovery and fuel drying reduces 3%wt of fuel moisture content and boiler efficiency increases 0.41%. Preheating air means a 35 °C increase of temperature or a 0.72% increase of boiler efficiency. The average accuracy of air control is 89.15%, indicating a 4.34% increase of boiler efficiency.View More
Exhaust Heat Recovery. A device like the one shown below can be attached to the flue to recover a portion of the exhausted heat. This heat can be used to preheat boiler make-up water. Take care not to extract so much heat that the flue gases condense (causing corrosion). Preheat Combustion Air. Efficiency Improvement - Up to 1 percentage point.View More
Insulate the jacket of the boiler to reduce heat losses. The improvement of the boiler efficiency depends on the surface temperature. • Install soot-blowers to remove boiler tube deposits that reduce heat transfer between the hot combustion gas and the water. The improvement in the boiler efficiency depends on the flue gas temperature. •View More

Boiler Efficiency Improvement Steps: After Analyzing heat losses in industrial boilers, boiler engineers or technicians can help you to increase your boiler efficiency by 6% – 10%.. Here are the few boiler efficiencies boosting steps listed below:. Complete combustion of fuel so that no unburnt is left behind is a good practice and will add to the boiler efficiency.View More
Dec 02, 2016 · Understanding what they are will help you recognize shortcomings in your boiler, which will empower you to resolve these issues and put your system on the fast path toward optimization. Continue reading to learn more the five secret factors that may be killing your industrial boiler efficiency. 1. Excess Air Effect on Industrial Boiler EfficiencyView More
a waste heat recovery system compris-ing both steam and power turbines, and combined with utilising scavenge air energy for exhaust boiler feed-water heating. This paper describes the technology behind waste heat recovery and the potential for ship-owners to lower fuel costs, cut emissions, and the effect on the EEDI of the ship. IntroductionView More
Oct 01, 2018 · Much like the return of condensate to the boiler, recovering the heat from the boiler blowdown can increase boiler efficiency. The blowdown valve is used to remove boiler water which contains soluble and insoluble solids. It helps reduce the level of dissolved solids in the boiler water to prevent the boiler scale.View More
travel across the boiler (heat exchanger). A boiler with two passes provides two opportunities for the hot gasses to transfer heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of theView More
Waste Heat Reduction and Recovery for Improving Furnace Efficiency, Productivity, and Emissions Performance or lean (excess air). Either way, it wastes fuel. Because there is not enough air for complete combustion, oper-ating the burners at rich combustion conditions wastes fuel by allowing it to be discarded with some of its energy unused.View More

Improve Your Boiler’s Combustion Efficiency Combustion Efficiency Operating your boiler with an optimum amount of excess air will minimize heat loss up the stack and improve combustion efficiency. Combustion efficiency is a measure of how effectively the heat content of a fuel is transferred into usable heat.View More
1. Fire tube boilers 2. Water tube boilers 1. Fire tube boilers : Fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermalView More
Waste heat boiler design. Waste Heat Recovery boilers are designed to recover heat from waste flue gases from DG exhaust, Furnace exhaust, Kiln exhaust, incinerator exhaust etc. to produce steam or hot water based on the application requirements of the plant. There are 4 basic requirements or inputs for calculating your waste heat from theView More
6 Soot Deposits and Fires in Exhaust gas Boilers quality and the above highly efficient and perhaps “overstretched” design, it also seemed that the tendency to fouling, i.e. soot deposits on the ex haust gas boiler tubes, had increased and, in some cases, had resulted in soot fires. In extreme cases, the sootView More
