Numerical study of heat loss from boiler using different ratios

Boiler – Fundamentals and Best Practices

Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 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
