Waste Heat Recovery From Flue Gases - c03.apogee.net

Boilers burning natural gas and No. 2 fuel oil can be retrofitted with economizers to recover sensible heat from flue gases. An economizer is a heat exchanger that captures waste heat from the flue gas and transfers it to the boiler feedwater. The heat exchanger is usually installed directly in the boiler stack.

fired heaters/furnaces. In both cases, waste heat recovery can lead to substantial fuel savings. Process heat from steam boilers Recovering waste heat often reduces the need for steam in a plant. Consequently the boiler's fuel consumption is reduced, as are greenhouse gas emissions and the load on the cooling system.

Boiler Economizers and Waste Heat Recovery

Boiler Economizers and Waste Heat Recovery. I Overview Two solutions exist for recovering the waste heat from boiler flue gases. Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%.

HEAT RECOVERY BOILERS - Thermopedia

The convective elements of boilers fired by municipal industrial or other waste materials are often referred to as heat recovery boilers although, apart from their geometry, they are more akin to the rear end of a furnace-fired boiler. Perhaps the most common heat recovery boiler is now the gas turbine heat recovery boiler.

Energy Tips Process Heating

greatest single heat loss. The energy efficiency can often be increased by using waste heat gas recovery systems to capture and use some of the energy in the flue gas. For natural gas-based systems, the amount of heat contained in the flue gases as a percentage of the heat input in a heating system can be estimated by using Figure 1.

Waste Heat Recovery - Zeeco, Inc.

Waste Heat Recovery. Waste heat recovery equipment reclaims heat from flue gas for use in other process units. The heat is transferred directly from the hot flue gas to a steam boiler or circulating thermal oil system. The quantity of flue gas and the associated exit gas temperature limit the amount of heat recovered.
