Combustion Theory

This presentation will explore the combustion process and how it affects condensing boiler performance. The following topics will be discussed: The combustion process and how it varies with a change in the fuel, the role of excess air and how it affects boiler efficiency, how combustion is analyzed and what the readings mean, and the relationship between excess air and flue gas dew point. We will also discuss Nitrogen Oxides (NOx), how they are formed and how to minimize them.

Learning objectives:

  • Describe the process of combustion, including the effects of using various fuels: natural gas, propane, oil.
  • Explain excess air as related to the combustion process, including its effect on sensible heat loss.
  • Describe the relationship between excess air, CO2 level, O2 level and Lambda.
  • Explain the relationship between excess air and the dew point.
  • Describe under what conditions NOx is formed and how it can be controlled.

High Efficiency Condensing Theory

This presentation will explore the theory behind gas-fired condensing boilers. The following topics will be discussed: Heat make-up of natural gas combustion and how it relates to condensing boilers, natural gas / air mixture for the most efficient combustion, latent heat recovery as a product of combustion gas condensation, burner requirements including excess air control to increase boiler efficiency, and the relationship between return water temperature and condensing boiler efficiency. In addition, we will elaborate on the heat exchanger materials in condensing boilers and design requirements.

Learning objectives:

  • Explain the theory behind high efficiency operation and application of condensing boilers.
  • Describe the effects of excess air for combustion and efficiency aspects.
  • Explain the water temperature effect on condensation together with operation control strategy.
  • Describe heat exchanger construction in condensing boilers and the importance of material selection.
