The major functions of an economizer are to reduce the temperature of the exhaust gas, raise the overall thermal efficiency of the boiler, and reduce coal consumption. The economizers used in coal-fired power plants can be classified into two types based on their material properties: the cast iron type and the steel pipe type.
They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water). Xinxiang Xinda boiler company supplies different economizer for industrial steam boiler or hot water boiler. For long-term consideration, a economzier is very cost efficient.

We also engineer and fabricate wet and dry steam accumulators.
Boiler economizer is part of the heating area of boiler, to heat the feed water into saturated water inside the flue ducting, due to its absorption of low temperature flue gas heat, the economizer reduces the exhaust temperature of flue gas, save the energy, improve the efficiency, so called as economizer.
Economizers are commonly used as part of a heat recovery steam generator in a combined cycle power plant. In an HRSG, water passes through an economizer, then a boiler and then a superheater. The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler.
Oct 18, 2017 · As the name may imply, the Economizer is a device built into a boiler to help improve the economy of the boiler. The water heading into the boiler has typically been preheated by some steam flow that was extracted, or bled, from the steam turbine.
The major functions of an economizer are to reduce the temperature of the exhaust gas, raise the overall thermal efficiency of the boiler, and reduce coal consumption. The economizers used in coal-fired power plants can be classified into two types based on their material properties: the cast iron type and the steel pipe type. Steel pipe economizers are generally used in ultra-supercritical boilers due to the high steam temperatures and pressures involved.
Jan 23, 2019 · Application of boiler economizer prices boiler economizer prices in Sugar Mill. Steam is very important for the sugar mill. Steam boiler is used for heating, gelatinization, and saccharify, etc. Heating equipment is equipped under mash kettle, and then steam produced by boiler economizer prices enter into the heating equipment, and then heat the raw materials for starch hydrolysis.
Clean Coal Technology Coal fired steam boiler is a combination of water tube and fire tube design, natural circulation, balanced draft unit, suitable for indoor installation and is provided with atmospheric fluidized bed furnace to burn the coal.
A boiler economizer is installed into the exhaust stream of the boiler. Exhaust waste heat is recovered by industrial finned tube that lines the inside of the economizer. The heat is transferred to the desired heat sink as it flows through the tubing: boiler feedwater, makeup water, process water and etc.
Economizer Replacement Restores Boiler Efficiency ~ By Ronald W. Elsner, Northern States Power, George H. Harth, Ernst H. Mayer and Daniel P. Schaper, Babcock & Wilcox Co.
Jul 30, 2019 · 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. Boiler Economiser and Waste Heat Recovery Concept. Boilers are generally designed to produce steam from water.
Boiler stack economizer in general is a form of heat exchangers that separates between hot fuel gas and water. The structure of economizer in fire-tube steam boiler that allows the recycle usage of excess heat from exhaust. The effect of using economizer on the reduction of heat losses and increasing the efficiency of fire tube steam boiler.
The boiler economizer is a tube heat exchanger located in the final part of the convective duct. In the economizer, water flowing into the boiler is preheated by flue gases.
The heat of combustion of coal in the boiler is used to convert water into steam at extreme temperature and pressure. The flue gases from the boiler make their journey through super-heated, economizer, air pre-heater and are finally exhausted to atmosphere through the chimney.
After design furnace, the next step to design thermal in steam boiler is calculate heat transfer surface in wall tubes, superheater, reheater, economizer, and air heater. The optimum heat transfer is the objective of this step to determine the requirement a number of tubes needed for the listed pressure parts above.
The Coal Steam Boiler can be used for the following business:Chemical plant,Textile plant,Food & Beverage,Garment manufacturing,Paper Plant,Printing and dyeing mill,Cement Plant,Fertilizer plant,Feed mills,Rubber factory.Schools,Hotel,Bath Center,Swimming Pool,Hospital,Hotel,etc.
Nov 03, 2019 · A boiler economizer acts as a waste heat recovery device, ensuring that this heat does not go unused. Instead, the heat is used to essentially preheat the water, so that less heat is required to bring the water to a temperature high enough to make steam.
A Boiler`s Economizer is, by Definition, Intended to Reduce Operating Costs by Recovering Energy from flue gas. This heat energy is transferred to water entering the boiler.
The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater.
May 01, 2011 · The steam drum is 6.5 ft in diameter and collects and distributes the water/steam as it continuously circulates throughout the boiler. Once the water/steam enters the drum from the economizer outlet header via the economizer connecting pipe, it is forced by gravity down pipes called downcomers.
The boiler economizer is an indispensable mechanical device for coal fired boilers, and is located at the boiler flue, where heat is captured from the flue gas in order to pre-heat cold water inlet or heat the boiler feed water.
A boiler or Steam Generator (prime mover) is an integral device in a fossil fuel power plant used to produce steam by applying heat energy to water. A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam.
DZL series coal fired steam generator is single drum water tube and fire tube generator, combustion equipment is chain grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area.
The boiler designers always keep the economizer water outlet temperature to about 25 to 35 degrees below the drum saturation temperature. This is done to mainly avoid steaming in the economizer. A steaming economizer generally is less reliable.
Boiler Economizers are waste heat recovery systems that recover heat from industrial boilers and include gas condensing, dual stage and feed water economizer systems. Studies have shown that over a 20 year period, 96% of the cost of operating a boiler. View More; Economiser For Coal Boilers
SZL Water Tube Coal steam Boiler SZL type is a double-drum water tube assembly travelling grate boiler (D type layout). The boiler body has an upper drum and a lower drum longitudinally arranged along the boiler.
