Boiler – Fundamentals and Best Practices

When heat is added to water, its temperature rises at a rate of 056°C (1°F) for each heat input of 2095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100°C (180°F) This rise in temperature can be detected and is called Sensible Heat
