Eclipse, a worldwide leader in combustion solutions for the glass industry, has released flat-flame and conical-flame throughport burner products to the market.
The two conical flame throughport burners are designed to be inserted through the port neck of a regenerative glass furnace. The WTPUG version 2 is a water-cooled, throughport natural gas burner and has a wide range of water jacket sizes and nozzle diameters, allowing for higher capacities. The WTPU version 1 is a water-cooled throughport oil-fired burner. It can be used as the primary burner or as a backup to a gas-fired burner, and it is capable of firing light or heavy fuel oil.
Both the WTPU and WTPUG burners are available to fit in the Eclipse Retraction Mechanism, and may be configured with NPT or BSP fuel and water inlet/outlet connections. Both types of burners are available in water jacket lengths from 1400 mm (55 inches) to 2000 mm (78.7 inches) in increments of 100 mm (3.9 inches).
Eclipse has also released the WGD version 2 throughport burner. The WGD is a water-cooled, natural gas burner, designed to be inserted through the port neck of a regenerative glass furnace. The burner produces a flat, fan-shaped luminous flame with excellent flame coverage over the glass. The new nozzle design incorporates flow straightening vanes to improve gas flow characteristics. This significantly improves the nozzle life and allows an increase in the maximum capacity to 1200 Nm3/hr (45,650 SCFH).
To provide precise flame control, the top burner nozzles are available with hole angles of 0º, 5º, 10º, and 15º, and the bottom burner nozzles are available with hole angles of 5º, 10º, 15º, and 20º. Additional nozzle sizes and geometries are available as engineered specials. The new nozzles can be retrofitted into existing burners. WGD burners are available in water jacket lengths from 1400 mm (55 inches) to 2000 mm (78.7 inches) in increments of 100 mm (3.9 inches).
