2020-10-17 · Designing the optimal boiler system. Your challenge: Non-condensing boilers can only work if the water returned to the boiler doesn't drop below the dew point of the moisture in the flue gas. Condensation of the flu gas can cause significant boiler corrosion while too high a temperature difference results in thermal shock..

Boiler Efficiency & Combustion Efficiency

2  · Boiler efficiency and combustion efficiency - All boilers operate under the same fundamental thermodynamic principles and therefore, just like any other piece of thermal transfer equipment, knowing the log mean temperature difference (LMTD), in this case, between the furnace temperature and the flue gas outlet then the theoretical efficiency can be calculated.

Boiler Efficiency | Kane International Limited

Boiler Efficiency. The objective of a boiler is to burn the hydrogen contained in the fuel with oxygen from the atmosphere to produce heat. Combustion efficiency analysers exploit the fact that by knowing the fuel (and its chemical composition) and measuring the flue gas temperature and either the oxygen or carbon dioxide level the efficiency of the boiler can be calculated.

Explaining Boiler Flue Regulations | Boiler Guide

A boiler flue is a pipe or duct that's attached to gas boilers which allows waste gases produced during the heating process to safely leave the building. You might recognise them as those black or white ducts that stick out of buildings expelling gas.

Flue Gas Dilution - Airflow Developments

To ensure a maximum of 1% CO 2 content at the outlet, the volume flow rate of diluted flue gases necessary for a given boiler can be calculated as follows: Flow rate in l/sec = 2.69 x rated input of boiler in kW. Where 2 metres of discharge ducting is not possible then the calculation is: Flow rate in l/sec = 4.44 x rated input of boiler in kW.
