Flue Gas Exhaust Thermometer - Controlled Combustion

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 fan power consumption

Exhaust Gas Steam Boiler

The reasonable optimal steam production of Exhaust Gas Boilers where no economizers are incorporated are consequently reached at a steam pressure of 3-4 bar (saturated temperature 143-151°C). In practice it is found that the pinch temperature shall be kept at minimum 25°C as a lower temperature difference will substantially increase the heating surface and the price of the Exhaust Gas Boilers .
