Boiler
Definition:
(n.) One who boils.
(n.) A vessel in which any thing is boiled.
(n.) A strong metallic vessel, usually of wrought iron plates riveted together, or a composite structure variously formed, in which steam is generated for driving engines, or for heating, cooking, or other purposes.

Hydrostat
Definition:
(n.) A contrivance or apparatus to prevent the explosion of steam boilers.
Example Sentences:
