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.

Conversion of Existing Coal-Fired Boilers to Natural Gas
natural gas. Boiler efficiency decreases are to be expected in the 3% to 4% range, depending on the current fuel and boiler design. Auxiliary power demand is reduced with natural gas firing because pulverizers, primary air (PA) fans, precipitators, coal handling system, sootblowers, and other equipment are no longer required.
