SAFETY BOILER WITH ~G~I EFFICIENCY
Con~entional boilers either fire tube type or water tube type are generally found with the following de~ects:
1, In order to sustain the high pressure of ge~erated steam, all the ~onstruction parts should be desi~necl with suitable thickness durable for such high steam pressure~
which can not be reduced to be thinn0r 50 that the produotion cost of boiler will not be reduced,
SAFETY BOILER WITH ~G~I EFFICIENCY
Con~entional boilers either fire tube type or water tube type are generally found with the following de~ects:
1, In order to sustain the high pressure of ge~erated steam, all the ~onstruction parts should be desi~necl with suitable thickness durable for such high steam pressure~
which can not be reduced to be thinn0r 50 that the produotion cost of boiler will not be reduced,
2, The heat conductivity of such thicker ~teel plates or tubes will be reduced so as to decrease the thermal ef~iciency of boiler,
3, Tha outmost boilsr shell should be insulated to prevent heat loS9 therefrom to increase ln~ulation cost and maintenance problem for the insulated material a~ the bo~ler shell s-till carry an appreciated heat which should be w~ll i.nsulated,
4~ The boiler shell directly rec~ives the hlgh pressur0 of steam inside the boiler so that~ once aocic1cntal e~plosion oocuring~ the outer broken scraps will direotly and rapidly spread outwards to cause serious damage to the surrolln~ings~
