Consulting - Specifying Engineer | Strategies to improve

Jun 23, 2020 · During winter operation, the heat recovery chiller can operate to meet the process cooling loads of the hospital while also providing hot water to reduce the demand on the boiler plant. Essentially, the building owner gets heat energy at virtually no cost because it is a byproduct of the cooling process.


The hot gas duct between the turbine and the waste heat recovery boiler is equipped with natural gas burners for supplemental firing. The fuel flow to these burners can be controlled to maintain pressure on the plant steam header. The waste heat recovery boiler is also equipped with an economizer in order to maximize waste heat recovery.

Heat Recovery with Boiler Stack Economizers

The condensing economizer improves waste heat recovery by cooling the flue gas below its dew point, which is about 135°F for products of combustion of natural gas. The economizer reclaims both sensible heat from the flue gas and latent heat by condensing flue gas water vapor (see Table 1). All …

Use Feedwater Economizers for Waste Heat Recovery

Generally, boiler efficiency can be increased by 1% for every 40°F reduction in flue gas temperature. By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years. The table provides examples of the potential for heat recovery. Example An 80% efficient boiler generates 45,000 pounds per hour (lb/hr) of

Demonstration project shows potential of Ultramizer

equipped with a high temperature economizer was selected from the candidate sites based on space availability and savings potential. An Ultramizer heat recovery system, sized for a 300 HP boiler, was then designed, fabricated, installed and tested on a flue gas slip stream of the boiler to demonstrate its savings potential.

Boiler | DOE boiler software is a hot way to save energy

Sep 19, 2006 · An economizer efficiently recovers wasted stack heat and transfers it to boiler makeup water or any other fluid. An economizer might reduce fuel usage by 5% to 10% by recovering this waste heat. Condensing economizers require more plant modifications and cost more, but provide higher heat recovery potential than conventional economizers.

Waste Heat Recovery Methods And Technologies - Chemical

Jan 01, 2013 · So, for greater heat recovery from fluegas, changing the stack and its material of construction may also be required. Heat reuse in the same process. Economizers for boilers. An economizer recovers waste heat from fluegases by heating BFW, and hence reduces boiler …

Boiler Efficiency | How to balance steam loads efficiently

Aug 26, 2011 · The oxygen content in turbine exhaust gases is sufficient to support the combustion needed for a downstream waste heat boiler. The heat recovery steam generator uses about 8% to 10% less fuel input to produce the same amount of steam as a package boiler. The boiler with an economizer generates 100,000 lb/h of saturated steam at 400 psig

Technology Toolbox: Increase your boiler's useful life

Oct 04, 2012 · Cannon Boiler Works ( leverages U.S. Department of Energy-supported technology in its advanced high-efficiency heat recovery system. Cannon's Ultramizer recovers sensible and latent heat, as well as water from the exhaust stream. The first two stages of the system use Cannon's Feedwater Heater technology.

Global Economizer Market (2021 to 2026) - Growth, Trends

Jun 04, 2021 · Growing application of economizer in waste heat recovery system in boiler is forecasted to offer various opportunities for the growth of the market over the forecast period.

Low temperature heat and water recovery from supercritical

One way to improve the efficiency of a coal-fired power plant is to recover the low temperature waste heat from the flue gas and use it to preheat combustion air or boiler feedwater. A low temperature economizer or flue gas cooler can be used for this purpose to …

On Demand Boiler Economizer | CBW Waste Heat Recovery …

The On-Demand boiler economizer removes waste heat from the flue gas, similar to the rest of our heat recovery line, but has some unique differences Our on-demand economizer operates only when your system needs hot water and is capable of offering a return on investment in less than a year, depending upon your current system.

Consider Installing a Condensing Economizer

water to the boiler. The recovered heat can also be utilized to preheat boiler feed-water, combustion air, or some other applications. Economizers also increasing the efficiency of the boiler will save you a lot of operating costs and eventually extend the life of the boiler system.

Economizer - Wikipedia

Modern-day boilers, such as those in coal-fired power stations, are still fitted with economizers which are descendants of Green's original design.In this context they are often referred to as feedwater heaters and heat the condensate from turbines before it is pumped to the boilers.. Economizers are commonly used as part of a heat recovery steam generator (HRSG) in a combined cycle power plant.

Boiler Tune-ups: Improve efficiency, reduce pollution, and

better boiler system efficiency measures, waste heat recovery, and other proven energy management • Add stack economizer to pre-heat boiler feed water. • Collect and return steam condensate to boiler feed water. • Add waste heat recovery device to preheat intake air or for process heating. Steam .

GAS & ELECTRIC Energy Efficiency Opportunities

Boiler economizers An economizer is a heat exchanger that uses the hot stack gas from a boiler and transfers its waste heat into the cold boiler feedwater. The boiler does not have to add as much heat to create steam, saving energy and money. For every 40-50°F drop in stack temperature, boiler efficiency increases by 1%. Stack recuperators
