2016/8/23 · Boiler fresh makeup water (typically 10 percent to 50 percent of the boiler feedwater flow rate) was used in the TMC unit to recover flue gas water vapor and heat.
In June of 2015, CWU added a condensing economizer (CONDEX system) that captures the waste heat produced from the boilers' flue gases. The recovered heat allows son and Discovery Hall (261,036 combined square feet) to be heated without burning additional natural gas, resulting in …
2021/3/3 · Summary. Economizers lower the consumption of fuel for a given steam demand. They also reduce thermal stress in the boiler and add heat transfer surface area to the boiler system. "By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years.".
For natural gas-fired boilers, the lowest temperature to which flue gas can be cooled is about 250 F to prevent condensation and possible stack or stack liner corrosion. The condensing economizer improves waste heat recovery by cooling the flue gas below its
What is Condensing Economizer? Condensing Economizers improve the thermal efficiency of boilers by cooling the exhaust gas below its dew point (about 135°F for combustion products of natural gas) and recovering the latent heat of water vapor through special designed heat exchanger units.
sensible and latent heat energy, contained in the 290 degrees Fahrenheit stack flue gas exiting the economizers. The boiler flue gas exiting the economizer still contains significant energy that can be recovered and used to heat other process requirementssteam.
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

Steam boilers, hot water boilers, and hot oil heaters with inputs up to 250,000,000 BTU/hr. (natural gas fired) BOILER EXHAUST APPLICATION Capacity: to 250,000 lb/hr steam Entering gas temps: 300 F – 800 F Heat sink types: Boiler feedwater, makeup
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. The economizer reduces the overall fuel
The Economizer and Heat Recovery Experts. E-Tech manufactures economizers and other waste heat recovery products that can save your company significant money on energy. Our heat recovery economizers, boilers and heaters have been engineered and distributed to customers since 1976. The Authorized Kentube Engineered Products Manufacturer.
Any exhaust gas stream with temperatures above 250 F has the potential for significant waste heat recovery. Consumers of waste heat energy can be found in almost any facility and are easy to locate. Typical examples include plant process heating, combustion air pre-heating, boiler feedwater pre-heating, and building heat.

3.6 Heat recovery boiler. The heat recovery boiler serves to cool the SO2 -bearing product gas and produce steam for electricity generation. Cooling occurs by feeding low-temperature boiler feed water around the fire tubes ( Fig. 3.4 ). The boiler feed water is condensed steam after electricity generation that has been conditioned in a deaerator.
CONDENSING ECONOMIZER INSTALLATION AT CHP-5 IMPACT: Heat recovery from flue gases increases boiler's efficiency by 10%. OPERATING PRINCIPLE A CE is a tubular heat exchanger installed behind a gas-fired boiler to recover heat energy from
Exhaust Heat Exchange Systems. Cain Industries has developed a complete line of heat exchangers for the three basic markets: Diesel and Gas Cogeneration, Boiler Exhaust Economizers and Fume Incineration. These systems have been designed solely for the recovery of waste exhaust heat from combustion sources.
