chemicals, and environmental and maintenance costs. Example A boiler, fired with natural gas costing $0.30/therm, produces 450 psig saturated steam and is supplied with 230°F feedwater. Using values from the tables, calculate the cost of producing steam. Steam Cost = 0.3 ($/therm) x 1000 x 1006 (Btu/lb) x 100 = $3.69/1000 lbs 100,000 (Btu/therm) 81.7

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.

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 coil in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater.

How Boiler Economizers Reduce Energy Consumption | Miura

Steam boilers use economizers to greatly improve efficiency as the system heats water for steam. The first economizer, patented in 1845, was used to improve the efficiency of boilers used in steam engines for mills and factories. By the 20th century, almost all steam engine boilers included economizers as a standard feature. Here, we will
