Natural gas burners, LPG (liquefied petroleum gas) burners, and propane burners are designed for specific fuel sources and have some key differences:
Fuel Source:
- Natural Gas Burner: Designed to operate on the natural gas supply delivered through utility pipelines. The primary component of natural gas is methane.
- LPG/Propane Burner: Designed to operate on LPG or propane, which are both stored as a liquid under pressure in cylinders or tanks. LPG is a mixture of propane and butane, while propane burners use only propane.
Energy Content:
- Natural Gas: Natural gas has a lower energy content compared to LPG or propane. As a result, natural gas burners may require larger orifices or different air-to-fuel ratios to achieve the same heat output as LPG or propane burners.
- LPG/Propane: LPG and propane have higher energy content, making them more efficient in terms of heat output compared to natural gas burners.
Gas Pressure:
- Natural Gas: Delivered through utility pipelines at a relatively low pressure, typically around 7 to 25 inches water column (WC).
- LPG/Propane: Stored under higher pressure in tanks or cylinders, usually ranging from 100 to 200 psi.
Burner Design:
- Natural Gas Burner: Typically designed with smaller orifices due to the lower gas pressure and lower energy content. They often have different air-to-fuel ratio requirements.
- LPG/Propane Burner: Designed with larger orifices to accommodate the higher pressure and energy content of LPG or propane.
As for the terms "old town" or "manufactured system," they don't inherently refer to specific types of burners. It's possible that they might be colloquial terms for certain types of gas burner systems or technologies used in specific regions or contexts. Without further context or details, it's challenging to provide a precise explanation for these terms.
It's essential to use burners specifically designed for the appropriate fuel source to ensure safe and efficient operation. Using the wrong type of burner can lead to inefficient combustion, potential safety hazards, and may also void warranties or insurance coverage. Always follow the manufacturer's guidelines and local regulations when installing or using gas burners.
