Abstract
The invention relates to a system and process for hydrogen combustion for industrial or steam generation applications, and more particularly to a hydrogen combustion burner or retrofit kit combustion system and process using a primary pure hydrogen fuel source. The burner or retrofit kit combustion system and process may also use one or more secondary fuels, such as natural gas, methane, propane, or the like, to reduce emissions of CO2. Additionally, the inventive burner, system and process can use a flame temperature reducing fluid for lowering the bulk flame temperature of the burner to increase equipment life and decrease equipment failure. The flame temperature reducing fluid can include flue gas recirculation (FGR), water injection, steam injection, and a combination thereof.
Claims37
A burner or retrofit kit combustion system for industrial or steam generation applications, the burner or retrofit kit combustion system further comprising:
- a stream of oxidant;
- a stream of primary pure hydrogen (H2) fuel configured to combust with the oxidant;
- and
- at least one burner nozzle downstream from the oxidant stream and the hydrogen fuel stream, the burner configured to combust the hydrogen fuel with the oxidant.
on system of claim 1.
A process for industrial applications or steam generation using the burner or retrofit kit
A burner or retrofit kit combustion system for industrial or steam generation applications, the burner or retrofit kit combustion system further comprising:
- a stream of oxidant;
- a stream of primary pure hydrogen (H2) fuel configured to combust with the oxidant;
- a stream of secondary fuel configured to combust with the hydrogen fuel and the oxidant for reducing emissions of CO2;
- a stream of a flame temperature reducing fluid configured to be introduced to lower the bulk flame temperature of the burner;
- and
- a plurality of burner nozzles downstream from the oxidant stream, the hydrogen fuel stream, the secondary fuel stream, and the flame temperature reducing fluid stream, the burners configured to combust the hydrogen fuel with the oxidant and the secondary fuel stream.
