Flue gas heat recovery through the acid dew point

By summing total inorganic components (Na+, S--, K+, Cl-) and adding the mass of carbon and hydrogen from the ultimate analysis, it is assumed that the remaining mass is oxygen. This composition is used by the model and is assumed to correspond to the specified higher heating value.

The losses can be calculated as: φ L 6 = m& bd ⋅ h′ + m& sb ⋅ hsb + m& atomizing ⋅ hatomizing (13) m& bd is the mass flow of blowdown water [kg/s], h ′ is the specific enthalpy of saturated water (blowdown water from steam drum) [kJ/kg], m& sb is the mass flow of sootblowing steam, hsb is the specific enthalpy of steam used for sootblowing (when leaving the boiler), m& atomizing is the mass flow of …

Boiler Stack Gas Heat Recovery

flue gas leaving the stack. Thus, the most effective method to save fuel is to recover as much sensible and latent heat of water vapor condensa-tion in the flue gas as practicable. Additional benefits of this energy recovery are: 1. An increase in stack gas density, which will permit a smaller stack diameter. 2.

Heat Recovery Flue Gas | Waste heat recovery system | exodraft

Flue gas heat recovery systems get more and more efficient. Newest systems can extract 10 % of energy with gas heaters and 5% for oil heaters. A flue gas unit not only works with exhaust but also with air, liquid, and steam. The system overall follows the same procedure as the waste heat recovery unit.

WASTE HEAT TO POWER SYSTEMS - US EPA

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.

the performance of the flue gas purification equipment. 3. FURNACE BOTTOM AND CHAR BED The lower furnace and the char bed are crucial for the entire recovery boiler process. The conditions in the lower furnace determine almost exclusively the performance of the process, that is, how the flows of sulphur and sodium as shown in Figure 1 are
