What is a High Efficiency Gas Boiler? | U.S. Boiler Company

Feb 08, 2019 · For condensing boilers, you need a return water temperature of 80°F or lower in order to achieve 97% efficiency. (Look at the efficiency curves from any common condensing boiler manufacturer to see this.) Put another way, you start gaining efficiency only when your return water temperature is approximately 135°F or lower. See the graph below.

Optimizing Boiler System Design According to Best Practices

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)

Stoichiometric or Theoretical Combustion is the ideal combustion process where fuel is burned completely. A complete combustion is a process burning all the carbon (C) to (CO 2), all the hydrogen (H) to (H 2 O) and all the sulphur (S) to (SO 2).. With unburned components in the exhaust gas such as C, H 2, CO, the combustion process is uncompleted and not stoichiometric .
