Jun 25, 2016 · Whenever the waste heat in the exhaust gases is not sufficient for generating the required amount of process steam, auxiliary burners which burn fuel in the waste heat boiler or an after-burner in the exhaust gases flue are added. Waste heat boilers are built in capacities from 25 m3almost 30,000 m3 / min. of exhaust gas.
GET A QUOTEThe boiler feed water economizer is basically a gas-liquid heat exchanger located after the boiler evaporator section. The economizer also uses a portion of the energy contained in the thermal oxidizer combustion gases (after the waste heat boiler) to preheat the boiler feed water before it enters the boiler evaporator section.
GET A QUOTEThe 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.
GET A QUOTEHeat 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.

GET A QUOTEWaste Heat Boiler (WHB) Just prior to entering the evaporator, the condensed water flows through an orifice or expansion valve. This restriction limits flow, and the water again vaporizes to a cold mist at 4.5°C [40°F]. This is where refrigeration occurs. The low temperature vapor pulls heat out of the chilled water loop, lowering its
