Introduction to Thermal Power Plants
A Thermal Power Station is a power plant in which the turbine is run by steam to generate electricity.
Steam is generated in the boiler of the thermal power plant using the heat of the fuel burned in the combustion chamber.
The steam generated is passed through steam turbine which is connected to the generator which generates the electricity.
The steam coming out of the steam turbine is condensed in the condenser and the condensate is supplied back to the boiler with the help of feed pump and the cycle is repeated.
Solar Thermal Power Plant
Solar parabolic concentrator converts the water in the receiver to steam.
Parabolic concentrator composed of many flat mirrors focused at the same point generates steam of more than 450 0 C temperature.
After economizer the heated water goes to the evaporator which evaporate the water and converts it in to the steam.
Steam after getting superheated runs turbine as per the necessity which is connected to the generator through shaft coupling. Generator is connected to the national grid through transformer.
Advantages of Solar Thermal Power Plant:

Solar Steam Cooking System
Several static concentrators reflecting / concentrating solar rays on one receiver each.
The steam generated in receivers due to solar energy goes to header.
The system is connected with feed water and steam pipelines that in turn are inter-connected with the boiler and cooking vessel system.
Advantages of Solar Steam Cooking No use of traditional and polluting source of energy. No recurring transportation problems for energy needs. No running cost. Very Low Maintenance Cost Very Clean Kitchen and Delivery of Hygienic Food.
Milestones in Steam Cooking Worlds First Steam Cooking System installed in 1997 Worlds Largest no. of Cooking Systems Worlds Biggest Cooking Systems, Cooks 50,000 meals a day Worlds highest place installed cooking systems
Solar Drinking Water System
Drinking water system is one of the best innovations
It is blessing for various food based industries, for whom dinking water is a very important component.
Impure water is the cause for many diseases in the country like Kidney failure, stones etc
How Does it work?
The working of the system is very simple.
The ground / surface water is passed through a radially outward membrane filter (needs to be replaced twice a year) where all the suspended solids are trapped. It also removes the impurities like Magnesium, calcium salts etc from the water to make it soft.
Then the water is heated to temperatures up to by 70 to 90 0 C by Gadhia Solar parabolic technology for 20 to 30 minutes.
This makes it germs free and pure drinkable water.
The whole systems works on Solar Energy, which is Clean and Green
No Electricity or fuel required. Can be implemented on large scale basis.
One time installation cost. No other fuel, operation cost
More than 25 years of life span
Attractive payback of 4-5 years
No Pollution- No Green House Gases
One time Solution for huge Drinking Water requirements.
Hot Water Application
By using Thermo siphon Technology.
In Thermo Siphoning Technology, the water is fed through feed water line to the receiver which comes from the storage tank and the outlet of the receiver sends the water back to the storage tank.
Unlike flat plate collectors, due to high temperature at the receiver, the thermo siphoning is much faster and there is no blockages in the tubes or freezing of water .
Hot Water Application
The other technology, where Thermic Fluid is used as media, is more suitable where the temperatures are much lower and temperature difference between available water and desired water is higher.
Thermic Fluid is passed through receivers to heat it up to 200 0 C or more.
By proper insulation, the water can stay hot for longer time as thermic fluid can store energy.
During long non sunny days, the thermic fluid can be heated up using back up system.
Solar Space Heating: Solar Space Heating is a very useful application for an area with low climate temperature and very good sun radiation (Ideal for higher altitudes) The concentrators heat up the Thermic fluid in the system. Heat exchangers are used to transfer the heat of thermic fluid to the air and heated air is used for the space heating. It keeps the room temp constant in winter in cold areas. It saves fuel for heating.
With Advance Solar Concentrated Technology, now it is possible to achieve temperatures up to 1200 0 C.
The parabolas concentrate the solar radiations in the combustion chamber.
Air is blown in the chamber, which keeps the temperature uniform through out the chamber
Any kind of waste ranging from Bio to Chemical to municipal can be incinerated in the chamber.
How it works?
With Advance technology, the system can achieve temperature up to 1500 0 C
Which is sufficient for burning human body
The system concentrates on a chamber where the body is kept, hot air is blown throw the blower in chamber, which help to acquire uniform temperature across the chamber
Saves tones of wood on daily basis
Pollution free solution
No electricity required
One time installation cost with life span of more than 25 years
Solar Air Conditioning and Cold Storage Systems Heating and Cooling constitutes almost 50% of our energy needs. Centralized solar air conditioning and heating systems powered by solar system can substantially reduce the cost of energy bill.
How Does It Work?
In this system water itself works as a refrigerant and lithium bromide salt solution as an absorbent.
Steam of 160 0 C temperature is generated using the parabolic systems.
This steam is supplied to traditional VAM system
VAM system generates chilled air which can be distributed to various parts of the building according to ducting done as per the requirement of the buyer.
There will be array of parabolas and receivers. One parabola would have around 380 glasses and each parabola will concentrate solar radiation on their individual receivers.
The temperature on each receiver will be as high as 1000 0 C. The water to be treated will be sprayed on the receiver where huge amount of water will be evaporated and converted to steam.
The steam is sent to a compressor, where it is compressed to up to 2 bar pressure, which will be circulated in sump I and because of temperature difference it will get condensed and send to sump II which is pure re-usable water.
The non-evaporated hot water returned from receiver is sent back to sump I, this will increase the temperature in sump I.
Sump I is covered with thick magnifying glass, . The evaporated water of sump I will be condensed on the glass pyramid in the form of water droplets which will be sent to sump II.
This way we are able to use most of the solar energy twice.
So in total more than 50% of the reusable water will be available on each sunny day.
There may be more than two sumps for which the treated water will be allowed to settle and filtered.
If the waste left out after treatment is non usable and hazardous, it can be dumped in organized land-fill which ensures water, soil and air pollution.
If the waste is Non-hazardous then it can be collected, dried and then can be converted to pallets to fire it for thermal energy. If it is un-usable then it can also be send to landfill site.
We can also provide Solar Incineration to burn such waste.
Solar Process Heat For Various Industrial Applications Technologies are there for providing complete solutions for numerous applications. We understand various applications, which requires energy in different forms by different industries and hence tailor made solutions can be integrated with the current system. Energy required in forms of Hot air, Thermic Fluid, Steam or pressurized hot water for any application. Applications can be in Dairy Industry, pharmaceuticals to food processing industries etc… to all kind of industries of IBR quality.
Solar Drying Systems Drying of agriculture and industrial products requires consistent hot air to remove moisture. With concentrated solar energy systems, drying can be much faster than sun and more cost effective than conventional fossil fuels. Large scale projects for both agricultural and industrial application are possible.
