The technology of pulverized coal preheating is aimed at achieving rapid ignition and enhancing stable combustion in low boiler load conditions [13, 14].By using the technology, a large amount of high temperature semi-coke and reductive gas is released from the pulverized coal, which can effectively alleviate the ignition challenges within the boiler furnace.

The DRB-4ZTM Burner
Maximum NOx Reduction for Coal-Fired Applications. Babcock & Wilcox (B&W) has a long history of successfully reducing NOx emissions on coal-fired boilers. We have sold nearly 100,000 MW of low NOx combustion equipment since the early 1970s. The DRB-4ZTM burner is the most advanced coal burner yet developed by B&W.

The novelty of this work is associated with a detailed analysis of the effectiveness of a developed co-firing coal-natural gas burner and the arrangements of the burners in the boiler for efficient combustion. Comparisons were made between the front-wall, the opposite-wall, and the tangential firing types.
FAQ
- QHow much NO x is removed from pulverized coal-fired industrial boilers?AFor pulverized coal-fired industrial boilers, NO X reductions between 15% and 30% are generally expected with the application of overfire air. Reburning is a combustion modification technology that removes NO X from combustion products by using fuel as the reducing agent .
- QHow much CO2 does a pulverized power boiler emit?AIn general, CO emissions from pulverized coal-fired power boilers are low (<50–200 ppmv) as the combustion system tends to be operated with sufficient excess air to maximize combustion efficiency . Local standards, rather than national standards, are generally established to limit CO emissions and can vary widely.
- QDo you test all your goods before delivery?AYes, we have 380% test before delivery.
- QCan industrial boilers reduce emissions from coal-fired facilities?AImprovements to the performance of existing power stations, industrial boilers and other facilities could lead to a significant reduction in emissions from coal-fired facilities. In 1991, China had approximately 500,000 industrial boilers used for light industry and district heating systems, consuming over 400 Mt of coal a year.
- QHow to reduce NO x emissions during pulverized coal combustion?ALow-NO x combustion technology can optimize combustion characteristics and reduce NO x emissions [ 13 ]. Air-staged combustion technology may be the most effective way to reduce NO x emissions during pulverized coal (PC) combustion [ 14 ]. According to the air-staged location, it can be divided into air staging in the burner and the furnace.
- QWhat is a burnout zone in a pulverized coal-fired boiler?ABurnout Zone: In this final zone, combustion air is added to complete the oxidation of the reburning fuel and to bring the boiler back to a normal operating excess air level. Pulverized Coal-Fired Boilers and Pollution Control. Figure 9
- QWhat are the control levels for a low-NO x burner?ANO X control levels for the application of low-NO X burners to wall-fired utility boilers typically range from 40% to 50%. Overfire air is a combustion modification technology that, like low-NO X burners, stages the combustion process to reduce NO emissions .
