Temperature difference between boiler inlet and outlet water
Thread Content
The temperature difference between the boiler’s inlet and outlet water is generally within 25°C. What factors are taken into account when setting this temperature difference?

Let’s start by telling me what type of boiler you have If it’s a steam boiler in a thermal power plant, with such a low temperature difference, how low would the thermal efficiency be? Even with a tea boiler, such a temperature difference means that either the water entering is too hot, or the water coming out is too cold.
The temperature difference between the boiler’s inlet and outlet water is a design requirement specified by end-users.
The document titled “The Impact and Effects of Increasing the Boiler Return Water Temperature on the Boiler Itself” was authored by Tianjin Hebei District Heating and Gas Company； It is worth mentioning that in our country, conventional pressurized hot water boilers are typically designed to operate at temperatures of 95/70 degrees, while atmospheric pressure hot water boilers are usually designed to operate at temperatures of 75/55 degrees. I want to design a flue gas-heated hot water system, so I am referring to the temperature difference between the inlet and outlet of hot water. I would appreciate some guidance from those who are more experienced
