The Heat Balance Equation Q = Q1 + (Q2 +Q3 + Q4 +Q5 + Q6) where : Q= available heat of burnt fuel 7 Q1= heat absorbed by working fluid Q2 to Q6 = heat losses Dividing both sides by Q and expressing as a %age we get : 100 = q1 +(q2 +q3+q4+q5+q6)
Protecting Boilers Against Flue Gas Condensation | 2017-08
Nov 05, 2019 · Thermodynamics doesn't care if the boiler is condensing; it only cares about balancing heat extraction with heat production. The mixing assembly protects the boiler by reducing heat extraction from the boiler to the distribution system, whenever the boiler temperature decreases below a specified minimum operating temperature.
You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C. Do not set it lower than this as you could increase the risk of contracting Legionnaires' disease. Legionnaires' is a form of pneumonia that's caused by bacteria in water.
Nov 27, 2017 · A thermodynamic balance between the boiler and distribution system is achieved, and boiler inlet temperature is high enough to avoid flue gas condensation. The key to the successful strategy shown in Figure 4 is a mixing assembly that senses and reacts to boiler inlet temperature.
