circulation boiler, which attempt to recover drastically the exhaust heat rather than for the waste heat, for the demand of co-generating system including gas turbine and diesel engine have been increasing recently. Moreover, Yoshimine is trying to make the total heat balance efficient now, employing the additional burning method.
Flue Gas Heat Recovery Systems (FGHRS) take advantage of heat within waste flue gases resulting from the combustion of gas in your boiler. This recovered heat is used to preheat the cold water entering the boiler, thereby lowering the amount of energy needed to warm the water up to the required level.
Heat recovery units. Waste heat found in the exhaust gas of various processes or even from the exhaust stream of a conditioning unit can be used to preheat the incoming gas. This is one of the basic methods for recovery of waste heat. Many steel making plants use this process as an economic method to increase the production of the plant with lower fuel demand.
The recovery of waste heat is a unique opportunity that benefits operating economy as much as it does the environment. With as much as 35% of an engine's fuel energy going into the exhaust flow as waste heat, there are substantial savings to be made when that energy is recovered.
Waste heat boiler design. Waste Heat Recovery boilers are designed to recover heat from waste flue gases from DG exhaust, Furnace exhaust, Kiln exhaust, incinerator exhaust etc. to produce steam or hot water based on the application requirements of the plant. There are 4 basic requirements or inputs for calculating your waste heat from the

Any exhaust gas stream with temperatures above 250°F has the potential for significant waste heat recovery. Consumers of waste heat energy can be found in almost any facility and are easy to locate. Typical examples include plant process heating, combustion air pre-heating, boiler feedwater pre-heating, and building heat.
An exhaust heat recovery boiler in which an exhaust gas discharged from a gas turbine/diesel engine into a boiler duct to recover a heat of the exhaust gas and ammonia is injected to and mixed with the exhaust gas to reduce nitrogen oxide contained in the exhaust gas, the exhaust heat recovery boiler comprising: a boiler duct of a horizontal installation type having an inner hollow portion
I had the idea of installing a drain heat recovery system on my high efficiency boiler exhaust. It captures wasted heat in the exhaust, by running half of the domestic water fed to the house
The Clayton Heat recovery boiler has all the benefits of the Clayton Steam generator. The small size and weight is of particular advantage on heat recovery applications because the boiler can be installed very near to the heat source to become part of the exhaust ducting - and many installation options are possible with the Clayton design.
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. Exhaust gas loss or waste heat depends on flue gas temperature and its mass flow,
In transportation, an exhaust heat recovery system turns thermal losses in the exhaust pipe into energy. This technology seems to be more and more of interest by car and heavy-duty vehicle manufacturers as an efficient way to save fuel and reduce vehicles' CO 2 emissions.  This technology can be used either on a hybrid vehicle or a conventional one: it produces either
With durable and corrosion-resistant exhaust gas heat exchangers for oil and gas heating systems, BOMAT heating technology from Ueberlingen at Lake Constance has been setting benchmarks in the
The exhaust gas heat exchanger uses the waste heat generated during energy generation in the form of flue gases. To make effective use of the available heating power, the residual heat of this exhaust gas is used to add it to a second medium - for example the heating water.
The DXL Two Stage Condensing Exhaust Economizer is specifically designed to recover sensible heat from within the exhaust and, more importantly, to also recover additional valuable latent heat as the exhaust is condensed. What makes the DXL Boiler Economizer unique is that it recovers heat in two stages.
In a conventional system, approximately two thirds of the fuel burned to generate power is lost as heat. Our engineered Exhaust heat recovery systems allow you to capture thermal energy from your exhaust gases, engine jacket water, and oil cooling systems. This recovered heat can be utilized to produce hot process water or steam for a wide variety of useful applications such as heating and

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
The steam flow from a heat recovery boiler can usually be increased by the addition of an economizer to preheat the feedwater before it enters the evaporator. The impact of adding an economizer to the evaporator previously analyzed in Fig. 3.1 is shown in Fig. 3.2.The gas temperature leaving the system is reduced substantially and the steam flow is increased approximately 75%.
Heat recovery boiler/steam turbine systems operate thermodynamically as a Rankine Cycle, as shown in Figure 2. In the steam Rankine cycle, the working fluid— water—is first pumped to elevated pressure before entering a heat recovery boiler. The pressurized water is vaporized by the hot exhaust and then expanded to
FGHRS recover heat from waste flue gases to preheat the cold water entering the boiler, lowering the amount of energy needed to warm the water up to the required level. Almost all modern boilers already have some sort of heat recovery built in, making condensing boilers much more efficient than older ones.
