Noise Transformer is so arranged that the transformer main body is disposed inside of a noise-shielding chamber, and a cooler for cooling the insulation oil circulated throughout the transformer is cooled with a liquefied gas ejected onto a cooling pipe for removing out of the cooler heat corresponding principally to the heat of vaporization of the gas, which is discharged into the atmospheric without being recovered.
Non-Reinforced Cut-Off Wheels are designed for use on fixed base type of machines where the work is securely clamped, guarded and where the wheel operates on a controlled cutting plane.
Non-catalytic Reactors employ processes, which uses oxygen supplied from the permeate side of a mixed oxygen ion and electron conducting membrane by means of a sweep gas at an elevated temperature. The sweep gas is formed by burning fuel in a sweep gas preheater. The nitrogen and hydrogen containing syngas is worked up into ammonia to produce nitrogen oxide containing gas, and the nitrogen oxides containing gas is used in the production of nitric acid. Non-catalytic reaction generally occurs in a flameless mode near the center of the reactor. A user-friendly simulation package is developed for multi-phase non-catalytic reactor analysis as a component for the advanced on-line process analysis system for pollution prevention.
