Low Temperature Corrosion in Boiler and Its Prevention .

In order to avoid or reduce the cold end corrosion the gas temperature leaving the heat transfer surface in boiler is kept around 150 degrees centigrade, ranging from 120 to 155. It is very important that the metal temperature of the tubes is always kept above the condensation temperature.

Exhaust Gas Boilers And Economisers for Marine Machinery .

- The gas temperature outlet in an exhaust gas heat exchanger is kept above 180°C to prevent low temperature corrosion occurring. There is about 10% water vapour in exhaust gas and also sulphur products and this can lead to suphuric acid forming which has a dew point of 140°C.

Boiler Efficien

dT = temperature difference between inlet and outlet of the boiler (o C) For a steam boiler the heat exported as evaporated water at saturation temperature can be expressed as: q = (m / t) h e (3) where. m = mass flow of evaporated water (kg) t = time (s) h e = evaporation energy in the steam at the saturation pressure the boiler is running (kJ/kg)

Myths and methods for protecting boilers against flue gas .

Nov 27, 2017· Notice that the water temperature entering the boiler is now 130°. Given the same 20 gpm flow rate through the boiler, the temperature rise across the boiler will only be 5.1° and its outlet temperature will be 135.4°. This higher-temperature water now enters the hot port of the mixing valve.

Boiler Performance and Mill Outlet Temperature - Bright .

The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal, while the lower limit generally remains as 65 degree centigrade, the upper limit is restricted to a lower level depending on percentage of volatile content in coal.
