the water that reaches the surface is not hot enough to produce steam, it can still be used to produce electricity by feeding it into a Binary Power Plant. The hot water is fed into a heat exchanger. The heat from the water is absorbed by a liquid such as isopentane which boils at a lower temperature. The isopentane steam is used to drive turbines, producing electricity. The isopentane then condenses back to its liquid state and is used again.

Ash Cooler Heat Recovery Under Energy Conservation SchemeIJAPEJOURNAL
A healthy fluidization state in circulating fluidized-bed combustion (CFBC) combustor is attributed to proper quantity of hot bed material (ash), which acts as a thermal fly-wheel. It receives & stores thermal energy from the burning of fuel (lignite) & distributes uniformly throughout the combustor & helps in maintaining a sustained combustion. The quantity of bed ash inside the combustor or size of the bed, depends upon boiler load & subsequently upon combustor temperature, lignite feed rate and ash % in lignite. As these parameters varies during process continuously, sometimes it becomes necessary to drain out the ash from the combustor. As & when differential pressure across the bed is increased from a justified level, draining of hot bed ash starts into Ash Coolers. Bed ash is drained at very high temperature of 850 oC & it also contains burning particles of lignite. This paper describes the heat recovery from bed ash, unloaded from the combustor into ash cooler, by pre-heating the condensate water of turbine cycle in a 125 MW CFB boiler of Surat Lignite Power Plant in India. The thermal performance of ash cooler was derived by doing a heat balance calculation based on the measured temperature of ash and cooling water with different load. From the heat balance calculation influence of ash temperature and ash amount on heat transfer coefficient is determined. Simulation is carried out around main turbine cycle indicates improved thermal economy of the unit, higher plant thermal efficiency, lower plant heat rate and reduce fuel consumption rate. Also simulation result shows that the heat transfer coefficient increase with ash amount and decreases with increase in ash temperature.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
The Internet of Things (IoT) is a revolutionary concept that connects everyday objects and devices to the internet, enabling them to communicate, collect, and exchange data. Imagine a world where your refrigerator notifies you when you’re running low on groceries, or streetlights adjust their brightness based on traffic patterns – that’s the power of IoT. In essence, IoT transforms ordinary objects into smart, interconnected devices, creating a network of endless possibilities.
Here is a blog on the role of electrical and electronics engineers in IOT. Let's dig in!!!!

CW RADAR, FMCW RADAR, FMCW ALTIMETER, AND THEIR PARAMETERSveerababupersonal22
It consists of cw radar and fmcw radar ,range measurement,if amplifier and fmcw altimeterThe CW radar operates using continuous wave transmission, while the FMCW radar employs frequency-modulated continuous wave technology. Range measurement is a crucial aspect of radar systems, providing information about the distance to a target. The IF amplifier plays a key role in signal processing, amplifying intermediate frequency signals for further analysis. The FMCW altimeter utilizes frequency-modulated continuous wave technology to accurately measure altitude above a reference point.

• COMPARISON OF GAS TURBINE AND STEAM ENGINES
4. INTRODUCTION
• GAS TURBINE IS A ROTARY INTERNAL COMBUSTION ENGINE. IT CONSISTS
OF COMPRESSOR, A COMBUSTION CHAMBER AND A TURBINE. THE GAS
TURBINE USES CONTINUOUS GAS FLOW AS THE WORKING MEDIUM BY
WHICH HEAT ENERGY IS PARTIALLY CONVERTED INTO MECHANICAL
ENERGY.
5.
6. APPLICATIONS OF GAS TURBINES
• THESE ARE WIDELY USED IN THE AIRCRAFT FIELD, i.e., FOR
PROPULSION OF TURBO JET AND TURBO PROPELLER ENGINES.
• WITH AVAILABILITY OF GAS FUEL, THE GAS TURBINES ARE
INCREASINGLY BEING USED FOR ELECTRIC POWER GENERATION.
• THEY ARE ALSO USED IN MARINE PROPULSION.
• THE GAS TURBINES ARE USED IN HIGH SPEED RACING CARS.
• THE GAS TURBINES ARE ALSO USED TO RUN THE RAILWAY
LOCOMOTIVES.
• THEY ARE USED TO OPERATE HOVERCRAFTS.
• THEY ARE USEDTO RUN ROTARY COMPRESSORS
7. CLASSIFICATION OF GAS TURBINES
I. ACCORDING TO CYCLE OF OPERATION
A. OPEN CYCLE GAS TURBINE- THE FRESH CHARGE IS SUPPLIED TO
THE COMPRESSOR IN EACH CYCLE. THE COMPRESSED AIR IS MIXED
WITH FUEL AND COMBUSTION OCCURS IN THE COMBUSTION
CHAMBER THE COMBUSTION GASES LEAVING THE TURBINE AFTER
EXPANSION ARE EXPELLED TO THE ATMOSPHERE. THUS, THE CYCLE BECOMES
AN OPEN CYCLE.
B. CLOSED CYCLE GAS TURBINE- IN ACLOSED CYCLE GAS TURBINES, THE WORKING
SUBSTANCE AIR UNDERGOES THE CYCLE, REPEATEDLY. THE COMBUSTION PROCESS
IS REPLACED BY HEAT ADDITION FROM EXTERNAL SOURCE AND EXHAUST PROCESS
IS REPLACED BY HAEAT REJECTION PROCESS TO THE SURROUNDINGS.
9. I. ACCORDING TO COMBUSTION PROCESS
A. CONSTANT-PRESSURE COMBUSTION GAS TURBINE-
THEORETICALLY, IT OPERATES ON AIR STANDARD BRAYTON
CYCLE IN WHICH THE COMBUSTION TAKES PLACE AT CONSTANT
PRESSURE BY SLOW BURNING FUEL.
B. CONSTANT-VOLUME GAS TURBINE –
IT IS ALSO CALLED EXPLOSIVE GAS TURBINE AND
THEORITICALLY, IT OPERATES ON THE ATKINSON POWER CYCLE.

11. COMPARISON OF GASTURBINE AND IC ENGINES
• MERITS-
1. SINCE THE GAS TURBINE IS A ROTARY ENGINE, ITS MECHANICAL
EFFICIENCY APPROACHES 95% QUITE HIGH COMPARED WITH IC ENGINES
2. THE WEIGHT OF THE GAS TURBINE PER KW POWER IS LESS THAN IC
ENGINE
3. POWER DEVELOPED BY GAS TURBINE PER KG OF AIR IS MORE THAN OF IC
ENGINE
4. THE SPEED OF THE GAS TURBINE IS HIGHER THAN THE IC ENGINES
5. THE COMBUSTION IS COMPLETE IN A GAS TURBINE, THUS EXHAUST IS
LESS POLLUTING AS COMPARED TO IC ENGINES.
12. • DEMIRITS-
1. THERMAL EFFICIENCY OF THE GAS TURBINE POWER PLANT IS
LOWER(15 TO 20%) AS COMPARED WITH IC ENGINES.
2. IT IS DIFFICULT TO START A GAS TURBINE AS COMPARED TO
AN IC ENGINE.
3. THE GAS TURBINE BLADES REQUIRE A SPECIAL COOLING
SYSTEM.
4. THE MANUFACTURING OF GAS TURBINE IS DIFFICULT AND
COSTLY.
5. FOR THE SAME POWER OUTPUT, THE GAS TURBINE
PRODUCES EXHAUST GAS APPROXIMATELY FIVE TIMES MORE
THAN THAT OF IC ENGINE.
13. COMPARISON OF GASTURBINE AND STEAMTURBINES
1. STEAM TURBINES USE STEAM AS WORKING FLUID. STEAM IS THE CHEAPEST
MEDIUM AND CAN BE GENERATED WITH THE HELP OF EASILY AVAILABLE FUELS.
THE GAS TURBINES ARE USING COSTLY FUEL WHICH CAN BURN EFFICIENTLY IN
ITS COMBUSTION CHAMBER
2. STEAM IS PRODUCED OUTSIDE THE TURBINE, THUS IT IS AN EXTERNAL
COMBUSTION ENGINE, WHILE THE COMBUSTION CHAMBER IS AN INTEGRAL PART
OF GAS TURBINE, THUS IT IS AN INTERNAL COMBUSTION ENGINE.
3. A GAS TURBINE USES LOWER PRESSURE RATIO OF THE WORKING FLUID AS
COMPARED TO STEAM PRESSURE IN STEAM TURBINE.
4. GAS TURBINE RUNS AT HIGHER SPEED THAN STEAM TURBINE.
5. A GAS TURBINE PLANT CAN EASILY BESTARTED OR STOPPED AS COMPARED TO
