Natural gas boilers employ one of two types of burners, atmospheric burners, also called natural draft burners and forced draft burners, also called power burners. Due to more stringent air quality regulations, low NOx burners and pre-mix burners are becoming more commonly used and even required in …

Over the years, liquid penetrant examination has been called many names: penetrant testing (PT), liquid penetrant testing (LP), and dye penetrant testing (DP). The American Society for Nondestructive Testing (ASNT) uses the name liquid penetrant testing (PT). The American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME B & PVC) and the National Board Inspection Code (NBIC

Convection is the transfer of heat within a liquid or gas when the liquid or gas is heated. As the liquid or gas is heated, it mixes with the cooler liquid or gas and heats the cooler liquid or gas. In a steam boiler, the convection process occurs when the fluid in the boiler is heated and becomes lighter and less dense.

Hand boilers demonstrate Charles's Law and vapor-liquid equilibrium. The colored liquid in the boiler is comprised of a volatile mixture of liquids (Methylene Chloride) that have a boiling point just above room temperature. The body heat from your hand causes the liquid to boil, which in turn makes the liquid evaporate, turning it to gas.

Gas boilers are fueled by natural gas and use a natural gas flame to heat water to a specified temperature or to its boiling point, thereby producing steam. They are the most common type of boiler used for heating applications in the United States.
