The role of industrial heat pumps in District Energy

District energy may not be the most common source of heating and cooling globally, but it is a growing technology that is widely implemented in places like Northern Europe and North America. One of the most significant developments in district energy over the last few decades has been the improvement of heat pumps. Heat pumps […]

Basics of fogging system for inlet air-cooling

Hot and humid summer weather affects turbine performance substantially, yet this is the most critical time for power plant service to users. A knee-jerk reaction would be to enhance installed turbine capacity to offset the deficit created by subdued performance and increased power demand. Instead of this costly route, experts discovered that since gas turbines rely on a constant-volume cycle, cooling inlet air could increase turbine performance markedly.

When are open cycle gas turbines the right option?

With the popularity of natural gas for power generation, it is not surprising that people keep inquiring about Open Cycle Gas Turbine (OCGT) and Combined Cycle Gas Turbine (CCGT) systems. But as with all products, each of these systems has its pros and cons. The OCGT has a rather straightforward operation that starts with fresh ambient air entering the compressor and ends with power generation as shown in Figure 1 below. This simplicity gives to OCGT several advantages over CCGT. However, do not get it all wrong; this cycle has also some drawbacks that may hinder its application in certain circumstances. Considering all these facts, when are open cycle gas turbines the right option?

Indicators and improvements for power plant efficiency

The average temperature for most tropical regions is about 35° C. This and the accompanying high humidity spells doom for power plants in such regions unless something is done to counter the effects. Large scale power-generation relies on gas turbines, which have limitations at higher temperatures. For maximum power plant power output and efficiency, inlet air temperature should be 15° C or even lower. Unfortunately, this is not normally attainable in humid and hot conditions unless refrigeration systems are used.

Renewable energy back up with Turbine Inlet Air Cooling

Power plays a high important role on the industrial and human progress improving our way of life and the economic development of our society. Continuous access to power must be supplied by power producers while maintaining customers demand and strict quality standards with competitive prices. These are only some of the main challenges faced currently […]
