Gas Boiler Burners for Commercial - Industrial Use with Hi

Jan 09, 2013 · In a standard D-style industrial boiler firing natural gas, a standard burner without FGR can achieve 85 to 100 ppm, while a burner with FGR with staged air/fuel can achieve 30 to 50 ppm. FGR rates can be 5 to 15 percent of total boiler flue-gas output, depending on a host of variables; most operators will not sense a difference in burner performance or interaction with controls.

for natural gas fired industrial boilers at <30 PPM NOx. This was achieved with either forced or induced FGR. In the years that followed, some burner suppliers were able to achieve <30 PPM NOx without FGR, See Figure 3 for an example of a gas flame from an industrial low NOx burner on a large watertube boiler operating at <15 PPM with induced FGR.

Combustion Pulsation and Noise - Process Heating

Aug 01, 2007 · A natural gas burner started the combustion and two waste liquids were sprayed in between the burner and the waste gas injectors. With increased plant production, a noise began to appear. In this case, the frequency was only one or two cycles per second, and was detected by rhythmic swelling of the fabric expansion joints connecting the economizer to the stack.
