How to calculate the Heat supply of heating Hot Water Boiler
To know the parameters of steam generated by heating hot water boiler, such as heating hot water boiler temperature and heating hot water boiler pressure, and then by looking up enthalpy entropy chart, determine the enthalpy value of steam, that is, calorific value, unit is generally thousands of coke. Divided by the sixth power of 10 is the focal number, and then multiplied by the steam production of the heating hot water boiler per hour is the heat supply of the heating hot water boiler.
Evaporation is measured by weight M (Kg). Q (J) consists of two parts: temperature rise heat and gasification latent heat.
1. The temperature rise heat Q1 (J):that is proportional to the heat capacity of the evaporating medium and the temperature rise of the evaporating medium is a very simple formula for calculating the heat rise of temperature. When the saturation pressure of liquid rises to the pressure above the surface of liquid with the increase of temperature, it begins to evaporate.
2. The latent heat of evaporation Q2 (J) is: Q2 H: evaporation enthalpy (vaporization heat) J/Kg of liquid
3, total heat supply Q=Q1 Q2
