Energy Tips – Steam

Benchmark the Fuel Cost of Steam Generation. Benchmarking the fuel cost of steam generation, in dollars per 1,000 pounds ($/1,000 lb) of steam, is an effective way to assess the efficiency of your steam system. This cost is dependent upon fuel type, unit fuel cost, boiler efficiency, feedwater temperature, and steam pressure.

Use Feedwater Economizers for Waste Heat Recovery

Energ Tips STEA Steam Tip Sheet 3 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

Boiler Economizer: Boost Your Boiler's Performance I RasMech

Mar 03, 2021 · High pressure steam boiler stack temperatures often range from 400 degrees F to 650 degrees F. That high temperature exhaust is wasting energy. That is where boiler economizers come in to reduce that heat loss. Remember, we need a fluid that can use the heat AND is at a lower temperature than the flue gas. Dry Economizer

What is a Boiler Economizer? (with pictures)

A heating and cooling specialist may provide advice on the installation and cost savings of a boiler economizer. Boilers operate by heating water to make steam, and using that steam for heat or energy generation. For the most part, a boiler is fairly efficient, but there is some heat loss when the byproducts of combustion are vented.

How to Calculate Boiler Economizer Efficiency

Studies have shown that over a 20 year period, 96% of the cost of operating a boiler system comes from fuel costs. Also, in a typical boiler system, 10% to 20% of energy input is lost in the form of heat escaping to the atmosphere. The installation of a boiler economizer helps to solve this problem.
