Title: Recovering method for waste heat from sintering machine
Inventor: TAKASAKI YASUTO
IPC: F23J15/00
Filed: 1981-03-27
Abstract: PURPOSE: To effectively recover sensible heat of hot waste gas from the ore discharging section of a Dwight-Lloyd type sintering machine by sucking the gas from descending pipes under wind boxes, removing dust, recovering waste heat, compressing the gas, and feeding it to a main duct.  
     CONSTITUTION: During the operation of said sintering machine, hot waste gas sucked from pellets passing through the ore discharging section 10 is fed to suction pipes 18, 18 through wind boxes 7, 7 and descending pipes 8, 8, and it is immediately passed through dust collectors 16, 16 to remove dust. The dust removed waste gas is passed through a heat recovering apparatus 15 to recover sensible heat of the gas, and the temp. of the gas is dropped. This waste gas is fed to an exhaust duct 19, compressed to a necessary pressure with a booth 20 in the duct 19, fed to a main duct and exhausted into the air through a main exhaust fan 11 and a dust 9, collector 12. This recovering method for waste heat is applicable relatively simply even to existing sintering equipment.

Title: Spiral flow type blower
Inventor: WATANABE TAKASHI
IPC: F04D29/58
Filed: 1979-04-13
Abstract: PURPOSE: To dercease a temperature of a driving motor greatly without changing its configuration and dimensions by instituting monolithic cooling fins in an internal side of an impeller blade.  
     CONSTITUTION: A cold flow 112 is generated by providing an internal side of an impeller 103 with a plurality of cooling flow fins 105 causing agitations of an ambient air by means of the cooling flow fins 105 when the impeller rotates. Hence, a surface temperature of a driving motor 107, and a coil temperature, or a temperature of a bearing 109 and a temperature of a casing 101 are greatly lowered. Therefore, even though a carrier fluid inside the spiral flow type blower is a high temperature fluid, a bearing 109 is cooled and a sufficient capacity is obtainable without increasing its configuration and dimensions.
