Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Challenges when Converting Coal-Fired Boilers to Natural Gas

since natural gas contains no Particulate Matter (PM), the PM emissions are virtually zero other than "background" PM present in the combustion airflow or that which is swept from the boiler. Regarding NOx, natural gas contains low fuel-bound nitrogen content and requires lower excess air for combustion than coal. These mechanisms can
