The typical operating range of an air compressor is between 40°F (4.4°C) and a little over 100°F (38°C). If the ambient temperature in the room was instead 100°F (38°C), the outlet temperature would then be 115°F

Inlet air temperature: T = 273K + 45 = 318K (45 ° C is Rotor vent air volume 0.95 m3/s Motor inlet and outlet wind pressure 2220Pa Table 3.Generator temperature field simulation results
The results shown in Fig. 7 and 8 are the inlet and outlet air temperatures of 250 MW SG with rated and 20% overloading conditions. This implies the good uniformity of hot air
The air velocity, air temperature, nonuniformity coefficient, and energy efficiency coefficient were adopted to evaluate both the air distribution and the ventilation performance
If the generator passage is too large it will allow entrainment of some of the surrounding warm air and raise the cold outlet temperature. Therefore for any given vortex tube of a fixed total flow, there is an ideal opening size for every

ECOSTAR direct and indirect type hot air generators are provided an outlet temperature up to 1000 ºC, and designed to operate with natural gas, fuel oil and light oil with a capacity range

The generator is built with internal air compressors as standard, and is extremely quiet in operation. inlet / outlet pressure, N2/Air Flow and status of the system with remote access for diagnostic control. Temperature range. From 5 –
More than 130 generators of these new designs have been shipped through the end of 1992, with approximately on -half in service. Theair-cooled generator product line iscontin-uing to evolve. The generator that is being applied with the LM6000 aeroderivative gas tur-bine (Figure 13) was tested and shipped in 1992.
A 12 MW gas turbine generator is required to operate at sea level with an ambient temperature T1 of 20◦C and a combustion temperature T3 of 950◦C. The following data apply. Assume constant specific heat Cp Cpc, and γ = = γc. Ignore the losses in the ducting, gear box and generator.
Extensive prototype testing ofeach of the new designs, both in the factory and under load at a customer’s site, has proven that the designs dBA, which is very satisfactory, and compares favorably with the design target of85 dBA. matchthe GE Frame 5,6 and ‘7 gas turbines. More than 130 generators of these new designs have

Inserting air filtration, silencing, evaporative coolers or chillers into the inlet or heat recov-ery devices in the exhaust causes pressure losses in the system.
