Turbine Gas Power Plants vs. Gas Engine

Are gas turbines losing their market share to gas engines? This question does not seem to leave the lips of power plant industry players. Gas turbines have conventionally been the sole technology of choice for larger sized heat and power projects. If you ask any industry expert, the situation could slowly but notably be changing, owing to the greater flexibility exhibited by engines. As the tradition in power plants is tested, we compare the two types of power plants (gas turbine and gas engine), giving the pros and cons of each.

Dubai’s Cooling Market: Benchmarking and Real Efficiency Analysis

Oil rich countries are grappling with dwindling revenue coupled with energy subsidies and higher energy per capital consumption. This situation has prompted the affected nations to develop networks and expand capacity using constrained budgets. Is there a way out of this quagmire? The US and Europe have successfully implemented benchmarking and retrofits for better energy performance. Can Middle East do the same?

Cooling Tower: Types, Work Process and Industrial Application

Industrial processes and machines generate such large amounts of heat that continuous dissipation is necessary for efficient operation. The heat must be to the environment. This is through a heat exchange process. That is the basis of the cooling tower technology. It is interesting that despite cooling towers being devices of the 20th century, knowledge about them is actually limited. Some people even believe cooling towers are sources of pollution, yet the only thing they release to the atmosphere is water vapor.

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?
