The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
Boiler Economiser ( Sometimes Called Economizer ) is the Energy improving device that helps to reduce the cost of operation by saving the fuel The economizer in Boiler tends to make the system more energy efficient In boilers economizers are generally Heat
Saving Boiler Fuel - 2015-11-3 · An economizer allows some of this otherwise lost energy to be recovered by using a heat exchanger located on the stack to heat boiler feedwater For every 40 q to 50 qF drop in stack temperature a 1% gain in boiler efficiency is realized
Boiler Economiser ( Sometimes Called Economizer ) is the Energy improving device that helps to reduce the cost of operation by saving the fuel The economizer in Boiler tends to make the system more energy efficient In boilers economizers are generally Heat Exchangers which are designed to exchange heat with the fluid generally water
· can be designed to burn a specific any number of different technologies but the main component to consider here is the heat source or otherwise known as the The is one of the most important aspects of a and is what burns inside the to generate the heat
Manufacturers In Chennai Top 10 Manufacturing companies in India 2019 suppliers and Exporters in Tamilnadu IndiaThe Concrete chimneys are available for a wide range of applications stove furnace or fireplace
First the burner needs to heat the incoming combustion air the flame Secondly if the air coming to the burner is quite warm you will need to little to make a similar amount of steam from the A mere 40 °F increase in the temperature of the fresh air can you about 1% in your
help to improve by extracting heat from flue gases discharged from the fireside of a can be classified as nonsteaming or steaming In a steaming 5-20% of the incoming feedwater becomes steam
By installing a fuel saving economizer on a combustion source the BTU recovered pays for all the equipment installed usually in 12 to 18 months (or an equivalent return on investment of 75 to annually) This means recapturing approximately 50% of the wasted $$ for every fuel dollar spent
the following six switching methods were identified as possible candidates for in existing : 1) to oil modification 2) /oil to coal replacement 3) /oil to coal modification 4) /oil to coal-oil mixture firing 5) /oil to coal-based firing 6) /oil to coal-based liquid firing A technical analysis of these switching methods indicated that each one has some potential application to existing

: In order to reduce the consumption in an an is to be installed The cost of the is $4000 but it will $1450/yr in costs The involves an additional $150/yr for maintenance Taking the interest rate to be 2 percent determine the discounted and simple payback periods
3 of with Where the exit temperature is above ca225°C and the ratio of flue gases to weight of water evaporated is low (eg < 3:1) the of an may be justified economically Under these circumstances the exit temperature may fall to < 140°C
Economizers typically increase the overall boiler efficiency by three to four percent Designers and operators of economizers must consider potential corrosion problems particularly in fuels containing sulphur Moisture containing corrosive sulphuric acid is likely to condense on any heat exchanger surfaces that fall below the acid dewpoint
According to the US Department of Energy installation of a feed water can raise the thermal of a and reduce consumption by 5 - 10% Waste Heat (WHB) a principle similar to waste heat recover heat generated in furnaces or exothermic chemical reactions at plants
The efficiency of the boiler increases with the increase in the temperature of the combustion air used in the furnace This is achieved by the increased temperature of the flue gas in the air
· By doing this an economizer is able to increase thermal efficiency This will typically result in a reduction of 1% in fuel cost per 10 degree rise in feedwater temperature
· The boiler with an economizer generates 100000 lb/h of saturated steam at 400 psig using natural gas At load the exit gas temperature is 320 °F Excess air is 15% The various losses (per ASME PTC 41) are shown along with the efficiency
: In order to reduce the fuel consumption in an industrial boiler an economizer is to be installed The cost of the economizer is $4000 but it will save $1450/yr in fuel costs The economizer involves an additional $150/yr for maintenance Taking the interest rate to be 2 percent determine the discounted and simple payback periods
Monthly Based On 5 Ton by at least 13% or more as compared with conventional heavy oil combustion Heavy oil (Bunker C oil) Price: around 1100 KRW (USD 110) In case of 5 ton (Around 400 / hour) Period of time : 1day 20 hours 25 days Operation - of monthly around USD 3100000
· An economizer uses the wasted hot flue gas to heat feed water on its way to the boiler If your steam boiler doesnt have an economizer or your economizer isnt working this should be the first priority Economizers save fuel and prevent damaging effects of feeding the boiler with cold water
