Free Chat2020-8-25 · What is boiler thermal efficiency? The amount of heat that fuel is fed into the boiler, most of which is absorbed by the heating surface of the boiler, produces water vapor. This is the effective heat used. Another part of the heat is lost, and the percentage of the effective heat is the thermal efficiency.

Free ChatSubstitute the solution's mass (m), temperature change (delta T) and specific heat (c) into the equation Q = c x m x delta T, where Q is the heat absorbed by the solution. For example, if a solution of salt water has a mass of 100 g, a temperature change of 45 degrees and a specific heat of approximately 4.186 joules per gram Celsius, you would
