Combined burner for firing oil and gas - has blades imposing rotating flow to ensure mixing and efficient burning

摘要

The burner pref. used for combined firing of gas and oil has separate feed lines for these different fuels. Their supply channels have guide blades for secondary air. Complete, residue free, combustion of oil and gas is ensured due to the mixing. The guide blades are arranged in two concentric rings, and a gas channel between these two rings is connected to gas supply pipe and to a gas nozzle. Another guide blade ring is built into the gas nozzle. These blades in the rings can be deformed or bent so that the air and gas flows are set in rotating movement. The oil is fed into central burner, which can be operated only with gas, only with oil or simultaneously with gas or oil.
