Gas-hot water boiler flue oil dew point temperature

Home / Gas-hot water boiler flue oil dew point temperature

Guide to Managing the Condensate for Condensing

The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.

Condensing Boilers and Dew Point: 'Tis the Season for

This condensation contributes 1,000 BTU per pound of condensate transferred into the water (at no additional natural gas use or cost!). So, there are two key things we have to look at: The return heating hot water temperature and the dew point of the flue gas. The Roles of Oxygen and Carbon Dioxide in Condensing Boilers. Boilers need oxygen to

Design requirements for chimney flue of Industrial Oil

2019-3-5 · 2. The gas flue and chimneys of oil and industrial oil gas fired boiler should be constructed by steel or reinforced concrete, and the lowest point of the flue and chimney should be set up with water sealed condensate water drainage pipes. 3. The thickness of metal fluesteel plate is generally 4~6mm.

Low Temperature Corrosion in Boiler and Its Prevention

Depending upon the ppm of SO 3 and water-vapor concentration, the dew point temperature can vary from around 90 degree centigrade to 140 degree centigrade. Condensation of these acids results in metal wastage and boiler tube failure, air preheater corrosion, and flue gas duct corrosion.
