Flue Gas Temperature Boiler

Temperature control in condensing and non condensing ...

Conventional boiler. A high return water temperature gives you safe operation. But make it too high and efficiency suffers. A shunt in a conventional boiler keeps the return water temperature above the flue gas dew point avoiding corrosion and thermal shock.

Flue Gas Exhaust Thermometer - Controlled Combustion

Flue Gas Exhaust Thermometer. A flue gas exhaust thermometer should be installed near the base of the breeching near the boiler to monitor the outgoing temperature of flue gasses. High flue gas temperature is typically an indication of soot build-up in the fireside of the boiler that causes reduced boiler efficiency corrosion failure of steel reduced heat transfer rates to the waterside of the unit draft loss excessive

Flue Temperature - an overview | ScienceDirect Topics

A flue gas analysis of a gas-fired boiler indicates that the CO 2 content is 8% with a gas flue temperature of 204°C (400°F). Determine the overall thermal efficiency of the boiler. Solution. By reading the monograph of Fig. 8.12 the combustion occurs with an excess air of 48% and excess O 2 of 7%. The overall boiler thermal efficiency is about 81%.

5 Factors Killing Your Industrial Boiler Efficiency & What ...

Dec 02 2016 · "Stack temperature" or flue gas temperature measures the temperature of the combustion gases when they leave the boiler. If the flue gas temperature is high it suggests the heat created by the boiler isn't being effectively used to generate steam. In other words a high flue gas temperature suggests heat is being lost. When looking to address heat loss through high flue gas temperatures it commonly

Flue Gas Waste Heat Boiler Thermal Efficiency Calculation

1. q2-flue gas heat loss The exhaust heat loss is the heat loss caused by a part of the heat that is taken away by the smoke of the boiler. Its size is related to the amount of smoke the smoke exhaust and the reference temperature and the sensible heat of the water vapor in the flue gas. q2 can be used as a simplified calculation formula: q2 = (3.55py +0.44) (tpy-t0) / 100
