part load

Turbines are rarely used because of the small part load efficiency, although land speed record cars do use them.

A drawback was that the power driving motors were not efficient enough at part load.

This applies to both full and part loads.

This gives the unit high operational flexibility, and excellent part load performance has been reported for such engines.

Those units will not work properly in part load, because they drag down the voltage below the operating range.

Batch type furnaces have relatively low initial equipment costs and heat each part load separately.

Often there is a minimum load that will be delivered, and an extra charge for part loads, so ring wound the suppliers before ordering.

Injectors work in pairs (idle, part load), or altogether (full-load).

It amounts to running a spark ignition engine at light or part load in a similar fashion to a diesel engine.

Only refuelling at part load or when shut down is now undertaken at AGRs.

However, they have two advantages that is a) coal can be burned in the steam generator as the supplementary fuel, b) has very good part load efficiency.

Hybrid power trains may also reduce the ICE-engine size thus increasing the average load factor and minimising the part load losses.

"We still have a long way to go because it's only operating at part load, but so far the part-load performance is better than we anticipated," Mr. Lacy added.

Dehumidification is greater with VAV systems than it is with constant-volume system, which modulate the discharge air temperature to attain part load cooling capacity.

The DSV Air and Sea Division handles air and sea freight between global destinations, including full loads, part loads, containers and flight palettes.

DSV Road handles European door-to-door transport, including full loads, part loads, mixed loads and special transports by 17,000 trucks within the company's network of subcontractors in 34 European countries.

Freight Consolidation Centres (FCCs) are distribution warehouses, situated close to town centre, shopping or construction site, at which part loads are consolidated and delivered to the target area resulting in fewer lorry journeys.

The ESEER is calculated by combining full and part load operating Energy Efficiency Ratios (EER), for different seasonal air or water temperatures, and including for appropriate weighting factors.

Whilst diesels are very expensive in fuel terms, they are only used a few hundred hours per year in this duty, and their availability can prevent the need for base load station running inefficiently at part load continuously.

A third way is to run the engine in HCCI mode only at part load conditions and run it as a diesel or spark ignition engine at full or near full load conditions.

In addition for the reliability of traditional base power generation, the engines have the capability to start and stop quickly and they maintain their efficiency in part load, which makes them well suited for peaking power production, smart grids, and emergency power systems.

The use of electronic control allows for special functions; such as temperature controlled injection timing, cylinder balancing (smooth idle), switching off individual cylinders under part load for further reduction in emissions and fuel consumption, and multi-pulse injection (more than one injection occurrence during one engine cycle).
