Energy Efficiency of Combined Ovens

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Multi-level Energy Management Strategy for Fuel Cell Vehicle Based on Battery Combined Efficiency and Identification of Vehicle Operation State

The design of energy management strategy is one of the main challenges in the development of fuel cell electric vehicles. The proposed strategy should be well responsive to provide demanded power of fuel cell vehicle for motion, acceleration, and different driving conditions, resulting in reduced fuel consumption, increased lifetime of power sources and increased overall fuel efficiency. The pu...

Sterilization by gas ovens.

A forced convection gas-fired oven has been designed which will sterilize a very heavy load of syringes and instruments and containers. It is superior to a gas-fired, infrared, radiant-heated oven which was designed for sterilizing syringes.

Energy Efficiency –

Electromagnetic radiation from microwave ovens.

Electromagnetic radiation from microwave ovens in Saudi Arabia was investigated by means of a field measurement survey. The survey was carried out for 106 ovens used in households and restaurants in Riyadh city. Ovens were between 1 month and 14 years old with operating power ranging from 0.5 to 4.4 kW. One oven was found to leak more than the 5 mW cm(-2) limit specified in the standard. Fiftee...
