The spelling of "auxiliary boiler" can seem confusing due to the combination of French and English elements. The first part, "auxiliary," is pronounced /ɔːɡˈzɪljəri/ (awk-SIL-yuh-ree) with stress on the second syllable. The second part, "boiler," is pronounced /ˈbɔɪlər/ (BOY-luhr) with stress on the first syllable. When combined, the stress falls on the second syllable of "auxiliary" and the first syllable of "boiler," resulting in /ɔːɡˈzɪljəri ˈbɔɪlər/ (awk-SIL-yuh-ree BOY-luhr). This term is often used to refer to a secondary device used for heating, commonly in ships or power
An auxiliary boiler refers to a specialized type of boiler that is installed in various industries, ships, power plants, and other facilities to provide additional steam or hot water when the primary boiler system is unable to meet the demand. It acts as a backup or supplemental source of heat and is typically used during peak periods or when the primary boiler undergoes maintenance or repairs.
An auxiliary boiler is designed to be smaller in capacity and has a simpler construction compared to the primary boiler. It is often used to provide additional steam or hot water for heating purposes, power generation, or other industrial processes. This boiler operates independently of the main boiler system and functions as a secondary unit to meet the temporary increase in demand.
Typically, an auxiliary boiler is fueled by oil, gas, or coal and can be either firetube or watertube depending on the application. It consists of a combustion chamber, heat exchanger, burner, fuel supply system, and control mechanisms to regulate the generation and distribution of steam or hot water.
The auxiliary boiler is essential in ensuring uninterrupted operations during periods of high demand or when the main boiler is out of service. It provides a reliable source of heat, contributing to the overall efficiency and reliability of the primary heating or power generation system.
The word "auxiliary" originated from the Latin term "auxiliarius" which means "helper" or "assistant". It entered the English language during the 17th century. "Boiler" has its roots in the Old English word "boilere" which referred to a person who boiled or brewed. It derived from the verb "bȳl-" which means "to boil" or "to bubble". The combination of "auxiliary" and "boiler" creates the term "auxiliary boiler", which refers to a boiler that provides additional support or assistance to the main boiler system.
