Gas turbines (GTs) are continuous-flow engines that run with fixed flames immediately after starting and at constant power, temperature, and flow. The burners work without any moving parts and their air volume allows for complete combustion. These features provide the necessary space to create a more efficient and versatile combustion engine. In particular, since the heavy-duty gas generators have medium compressions and adequate enclosures, they can burn not only high- and medium-BTU fuels, but also low-BTU fuels. Because of this, the machine can change a lot of oil. Dry Low Emissions combustors, which used to only burn natural gas, have gradually been adapted to accommodate the increased use of alternative fuels. The first paper presents the basic technical concepts that guide the essential oil sector. It also examines the range of other GT fuels that currently come from lean gases (coal bed, coke oven, furnace gas…) to refinery gas streams (LPG, olefins) and from volatile liquids (naphtha) to heavy hydrocarbons. This “oil feed” also includes natural products (biogas, biodiesel, and ethanol) and mainly blended with pure hydrogen, the future fuel. This paper also shows how, historically, land-based GTs have gradually achieved new oil fields through continuous engineering work, lab testing, technical development, and field validation.

The current decade will see disruptive changes in electricity as a significant reduction in GHG emissions, particularly CO emissions.

, has become a global, unavoidable necessity [1]. However, as stated by the IEA [2], the thermal power sector will survive, in the beginning, to provide additional energy that will be needed by the electricity demand of the economy, in particular, the transport sector. Next, the heating sector will continue to play an important role as power grids will need dispatchable units and “circular storage” to support grids and reduce the spread of renewables. At the moment, among the thermal power plants, gas turbines fixed on land are the ones that want to support the electricity revolution while meeting all the requirements, including performance, reliability, controlled emissions, and the ability to shave more, with quick start and control [3] ]. The irreplaceable role that electric power turbines are responsible for and how they can contribute to a decarbonized economy in conjunction with the advent of hydrogen as an energy carrier has been discussed elsewhere [4, 5].

In addition, gas turbines have the added advantage of fuel flexibility, a key factor in dealing with the volatile and uncertain future fuel market. Indeed, they have managed to produce a wide range of fuels, starting from natural gas and light distillate – which are their traditional fuels – and now include a wide range of different types of fuel and beverages.

This paper aims to review the major oil fields that have been successfully explored and have natural gas turbines installed over the years, based on the author’s personal experience. In order to better understand the reasons for this success, we will first explain some of the most important things about the technology of this machine. It will also show some interesting developments in the process of growing oil.

In most cases, oil flexibility is possible not only in terms of high oil consumption but also in achieving reliable oil change. In today’s power plants, this must be done automatically or at the push of a button. The simplest and most common form of renewable energy is dual fuel energy, which usually combines natural gas (NG) and light distillate (LD) oil for gas-fired power plants [6]. However, two cases must be distinguished because the expectations from the general manager depend on the type of work they provide:

The peak shaving service is characterized by few hours of use but the limitation of “dispatchability” that is permanent, which can respond to changes in the power supply over time, and requires a faultless start and quick access to the desired load; here, the plant operator’s attention is focused on maintenance costs;

“Base-load” or “semi-base-load” operation refers to long periods of operation, where the operator focuses on fuel costs that represent up to 60% of his O&M costs.

Figure 1 shows a “pyramid of merits” for gas turbines designed for high shear and load-carrying applications, respectively. In both cases, the goal is to maximize the profit per kWh produced by the unit’s load capacity.

For the core shearing task, the necessary conditions are: (i) initial preparation, and, in particular, the ability to start black; (ii) access to oil, meaning oil reserves; (iii) the fastest time; and (iv) cost savings since high-shear operations greatly increase the “maintenance factor” due to multiple start-ups/shutdowns, rapid changes, and high-speed cycles. Here, the double fuel capacity represents an additional security because it will avoid the economic damage that may result from the failure to start at the request from the transmission point. For GT it usually burns NG, which stands for most of the time, the secondary fuel can be lighter, which is rarely used. However, in some areas without gas and light distillate (for example, in some remote islands), the possibility of starting with other fuels, such as petroleum gas, is very important. However, efficiency is still very important.

In a base-load or semi-base-load operation, fuel availability is important, but the focus is on getting more fuel without disrupting and reducing fuel costs. Indeed, GTs working in large industries such as refineries, petrochemicals, or steel, often work long hours, sometimes non-stop for an entire year. That’s where alternative access and economic fuel get their full value.

Therefore, the purpose of this paper is to evaluate the flexibility of fuel in all its forms by showing the benefits it can bring in many sectors of the industry, especially when this quality is combined with energy conversion methods, including integration and integration, as well as the intelligent use of residuals. or lower secondary energies [7].

Today’s gas turbines operate according to the Brayton cycle, in which the heating element is produced by burning fuel in a continuous flow of air [8]. For a number of reasons, this cycle is very good for fuel rotation. Initially, the three cycle steps (compression; combustion; expansion) are carried out in sequence and in separate parts of the machine. When the measured load arrives, both air and fuel enter the burner at a constant temperature, temperature, and pressure, creating a steady state and temperature that helps keep the fire stable. These stable conditions and the absence of any moving parts in the burner provide more space for the development of portable combustion devices that can match many goals, the most important being complete combustion, low NOx emissions, and high fuel efficiency, the focus of this article. In addition, a large part of the combustion test work can be done in a single electronic assembly, unlike the rest of the machine, which helps to improve ideas or new designs [9, 10].

Boilers also have continuous flow and permanent flames [11] and can replace oil. However, the main difference is that GTs work under pressure (up to 30 bars) and use combustion air, which makes the kinetics of burning faster and more intense, even against difficult fuel. So the flames are shorter, so the combustion chambers are smaller. In addition, the combustion heat is directly converted into mechanical energy while the combustion gas itself acts as a driving fluid that rotates the mechanical shaft. Instead, the conversion of energy in boilers continues
