POPULAR MISCELLANY. 



Explosion of Kitchen Boilers. The most 

 common cause of the explosion of kitchen- 

 range boilers is frost. If the pipes are frozen 

 so that the steam raised by the fire can not es- 

 cape, the danger of an explosion is very great. 

 This should be prevented, where there is a lia- 

 bility of the pipes being frozen, by protecting 

 the pipes and apparatus generally from the 

 effects of frost. Protection may be given 

 by covering the pipes with hair felt. Some 

 boilers are in danger of explosion from the 

 failure of water supply ; but in the modern 

 system of cylinder the hot-water tank is not 

 entirely emptied, and a sufficient supply of 

 water is usually left to carry the fire several 

 hours. Boilers in districts where the water 

 is " hard " may fail in consequence of the 

 accumulation of an incrusted deposit within 

 them and the pipes, whereby the pipes may 

 be in time stopped up. The pipes, however, 

 usually give warning of this danger long de- 

 fore it becomes imminent, in the shape of vio- 

 lent noises and vibrations proceeding from 

 the apparatus, which become unendurable 

 and have to be removed before the explosion 

 takes place. Finally, a safety-valve is a sov- 

 ereign preventive of explosions from what- 

 ever cause.
