Boiler Economizers | CBW Industrial Boiler Waste Heat

Can be used on small and large systems burning natural gas, and condensing or non-condensing flue gas environments. Inlet temperatures 40F to 250F; What is the difference between a regular boiler economizer and a condensing economizer? The difference is the temperature range in which the economizer is operated.

gas. The indirect contact condenser prevents boiler make-up water from contacting the condensate from the flue gas and also allows the flue gas to be cooled below the dew point thereby extracting more heat. A condensing economizer is environmentally favorable because it reduces CO2 emissions. The Heat Recovery System allows less fossil fuel to

Flue Gas Condensers | CleanBoiler.org

Using feedwater-cooled finned tubing, our condensing economizer cools exhaust gases below their dew point, releasing latent heat bound up in the vapor. The amount of recaptured heat is considerable — about 1,000 Btu per pound of condensate. The CO2 reduction is also significant: one cubic foot for each cubic foot of natural gas saved.

Condensing Economizers – Below the Dew Point – | EM Magazine

Feb 21, 2017 · By preheating the boiler feed-water with energy harnessed from exhaust stack gases, economizers help reduce energy demand and save on fuel costs. In fact, the installation of a condensing economizer can result in well over 10% increase in fuel efficiency and usually is still a viable option if a standard boiler economiser is already fitted.

Measurable non-energy benefits of the condensing economizer are: Enabled recovery of 2 million gallons of water from the boiler stack in the economizer. Water generated is used in cooling towers. This water will also be added to the steam system as boiler make up water due to a low pH and hardness.

Case Study: Condensing economizer in boiler

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 hydrocarbon fu-els release significant quantities of water vapor as a combustion byproduct. The

The non-condensing section of the economizer recovers energy by preheating the boiler feedwater.

Boiler Economizer Types And Efficiency Calculation--ZBG

Condensing economizers. Condensing economizers are designed to accommodate the corrosive fluids generated when condensing the moisture out of the flue gas. There are 2 types of condensing economizers: heat exchanger and direct contact (spray). They capture much more heat and therefore can raise the overall boiler efficiency by 10% to 15%.

The application difference between an economizer and condenser is that economizers are primarily used to heat a smaller volume of water to a high temperature for boiler feed water, and condenser units heat a larger volume of water to a lower temperature. Up to 90% of the heat normally lost through boiler flue gas stack emissions is recycled

Considerations When Selecting a Condensing Economizer

Stack Economizer. Typical gas-fired heaters and boilers send 20% or more of their consumed energy out the exhaust stack. This loss can mean that for every dollar spent on fuel, the boiler system returns only 65 to 70 cents worth of useful heat after transmission losses. If your plant operations require intensive hot water usage and your boiler load exceeds 100HP, the super efficient FLUE GAS HEAT RECLAIMER (Stack Economizer) …
