Gas Conversion Burner Combustion Chambers


The combustion chamber for a gas conversion burner is commonly located in the ashpit of a coal-fired boiler or furnace. Figure 2-10 illustrates the positioning of an upshot gas conversion burner. Note that the burner head port is located 1 inch (plus or minus 1?4 in) above the grate level. This is a standard measurement when installing an upshot burner in the ashpit of a furnace.

The manufacturer’ s installation instructions provided with a conversion gas burner generally include specific instructions on the preparation of the combustion chamber. The main points you should remember are as follows:

• All openings in the boiler must be sealed.
• The combustion chamber must be thoroughly cleaned.
• Heat exchanger surfaces must be protected against concentrated heat.
• All nonheat transfer surfaces must be protected.
• The combustion chamber must be designed to contain combustion, to radiate heat, and to insulate the ashpit.

Gas Conversion Burners


A gas conversion burner is used to convert heating equipment designed for coal or oil to gas fuel use (see Figure 2-8). The boiler or furnace must be properly gastight and must have adequate heating surfaces.

A characteristic of gas conversion burners is that pressure will sometimes build up in a furnace due to puffs or backfire resulting from delayed ignition and other causes. Local heating codes and regulations usually stipulate that furnace doors be held tightly closed by spring tension only (in other words, not permanently closed) in order to provide a means for relieving pressure. Figure 2-9 shows an example of a door spring that can be used for this purpose.
