  • The Fundamentals of Heat Transfer - Chem-Aqua, Inc.

    May 04, 2021 · Convection happens when there is a difference in temperature between two parts of a liquid or gas. For example, as water is heated in a pot, the less dense hotter water rises to the top of the pot while the more dense cool water sinks to the bottom, setting up a natural circulation. A steam boiler functions in much the same way. RadiationLearn More

  • Radiation‚ Convection‚ and Other Losses

    The Boiler Efficiency Calculator takes into account only major energy losses‚ which typically represent 10 to 20% of fuel input. The major energy losses fall into two categories: stack losses‚ and radiation and convection losses. This section deals with the second type of losses‚ that is the heat lost to the surroundings from the warm surfaces of a boiler or high-temperature water generator.Learn More

    steam boiler. The passage of heat from one body to another, or from one part of the same body to another part at a lower temperature, is called conduction. Heat from the furnace reaches the water within a boiler by conduction through the plates, and is diffused throughout the entire volume by the same process, assisted by convection. HeatLearn More
