Improve Sustainability on a Shoestring | Chemical Processing
Jan 25, 2016 · To maintain these limits, the boiler may need tuning more often than the specified 24-mo cycle. Good communication between plant operations and the boiler operator is key to obtaining further efficiencies. Alerting the boiler operator to process changes or upsets will help that person better deal with load changes.

Boiler Combustion Control and Monitoring System
The boiler combustion control and monitoring system was installed on a 25 MMBtu/hr steam boiler located at the Watervliet Arsenal in New York. A one-year test conducted between February 2011 and March 2012 demonstrated a 4% fuel savings for typical utilization with natural gas. The efficiency gain is due to a reduction in oxygen in the flue gas

How do burner combustion control systems work?
Jan 13, 2015 · Each boiler has a boiler master, which is an A/M/bias station that handles the firing rate for that boiler. In AUTO, the boiler master receives the plant master output, biases it, and sends that percentage to the fuel and airflow controllers. In MANUAL, the boiler master output is adjusted by the operator.

Signs of incomplete combustion are a smoky exhaust, a yellow flame, flame failures, and sooty boiler tubes. It is a good idea to tune up a boiler annually to ensure the combustion process is optimized. Typically, excess air of around 10% for a natural gas boiler is optimal to ensure complete combustion and peak efficiency.
