RENEWABLE ENERGY SOURCES
We are conducting Research & Development on different sources of energy like Solar and Energy fron Oceans.
We offer consultancy and development / design of equipment to harness energy from these sources.
CSP THERMAL TECHNOLOGY
Solar thermal power plants produce electricity in much the same way as conventional power stations. The difference is that they obtain their energy input by concentrating solar radiation and converting it to high temperature steam or gas to drive a turbine or engine. Four main elements are required: a concentrator, a receiver, some form of heat transport media or storage, and power conversion. Many different types of systems are possible, including combinations with other renewable and non-renewable technologies, but the four most promising solar thermal technologies are:
  1. Parabolic Trough Concentration System.
  2. Central Receiver or Solar Tower System
  3. Parabolic Dish Concentration System.
  4. Linear Fresnel Reflectors System.
    Out of the above four methods, Parabolic Trough Concentration System is most frequently used for large solar power plants. Parabolic trough-shaped mirror reflectors are used to concentrate sunlight on to thermally efficient receiver tubes placed in the trough focal line. In these tubes a thermal transfer fluid is circulated, such as synthetic thermal oil, heated to 400°C+ by the concentrated sun’s rays. This oil is then pumped through a series of heat exchangers to produce superheated steam. The steam is converted to electrical energy in a conventional steam turbine generator, which can either be part of a conventional steam cycle or integrated into a combined steam and gas turbine cycle. For complete utilization of solar energy, a combined solar power plant along with the water desalination plant would be most appropriate as waste energy in the steam condensation is utilized for water distillation.

CSH (CONCENTRATED SOLAR HEAT)
Concentrated Solar Heat Energy Source for Industry
  • Many industries require energy in heat form for various processesas in Chemicals / Process industries, Food Processing, textile processing, cement, steel etc. to name a few.
  • Heated fluid at temperatures up to 500º C could be provided as heat source for any type of industries using CSP Thermal technology with tremendous savings in costs.
  • Solar heat source for cooking, hot water utility, water desalination.
  • Waste heat in any of the above could be utilised for productive use resulting in Energy Conservation.
PARABOLIC TROUGH
It is planned to use parabolic trough type glass mirrors for thermal concentration for the CSP thermal plants for best conversion efficiency. Accordingly, we have designed the parabolic trough type glass mirrors using thin ultra clear glass sheets of low iron content and with highest transparency. This will also reduce the effective weight of the mirrors requiring light support frame structures and subsequent lighter tracking systems. Such quality glass sheets are not manufactured in India and we plan to import them.

Unique design, with special bending and tempering process for manufacturing for parabolic mirrors using ultra clear low iron content thin glass sheets has been planned. Parabolic trough mirrors are made using specially designed furnace with conveyor system for uniform heating of thin glass sheets in order to avoid breakage. By making use of accurately designed moulds it is to produce accurate parabolic shaped glass sheets. These bent glass sheets are then coated with metallic layer as reflecting surface by vacuum metallizing coating using pvd (physical vapor deposition) process to make highy reflective parabolic trough mirrors.
PARABOLIC DISH
Accurately bent and tempered parabolic dish type of mirror sections will also be produced using same technique as with trough typw mirrors.

RECEIVER TUBES
How much of the heat incident on the earth’s surface could be converted to the usable heat for generation of steam mainly depends on the efficiency of two most important components of the thermal concentration field namely the parabolic trough mirrors / reflectors and the receiver collector tubes.

The receiver tubes for parabolic trough system consist of a high heat resistant steel tube encased in a borosilicate glass tube with annular space evacuated. The inner steel tube is meant for heat transfer from concentrated solar rays to the HTF flowing through the tube. These steel tubes are externally coated with a dark colour, mostly black metallic oxide coating for better absorption of the HTF heat and low emission losses. The vacuum is created in the annular space to minimize the emission losses from the HTF within the steel tube. With these type of receiver tubes currently available, it is claimed that they have maximum absorption (Up to 94%) and minimum emission losses (Up to 14%). The aim for the process used for designing and manufacturing these receiver tubes is to increase the absorption rate to over 96% while minimizing the emission losses to below 8%. This is achieved by innovation in the design, use of distinctive materials and using a unique process.
UNIQUE FRAME STRUCTURES TO SUPPORT PARABOLIC TROUGH MIRRORS,
       RECEIVER TUBES AND THEIR SOLAR TRACKING SYSTEM
Our unique modular design for the frame structures and their solar tracking system uses combination of aluminum and stainless steel sections making it lighter in weight but sturdy in design to not only support parabolic trough type glass mirrors but also minimize corrosion and withstand high wind speed forces during the operations with long operating life. We have used a unique method of fitting the mirrors with gaps between the rows of mirror sections on the frames in order to minimize the effect of the high speed winds.

The aperture size of the parabolic trough type mirrors shall be designed to be approx. six metres and modular length shall be 12 metres. These module could be dismantled cross brackets of uniform design and the connecting pipes to form a module of 6M x 12M. The total length of one mirror unit shall consist of 10 modules totaling 120 metres having total thermal collection area of 720 square metres. The solar traction actuators shall be fitted at centre at 60 metres from each end. The actuators shall be of hydraulic motor type with wheel and pinion arrangement.
THERMAL STORAGE
UNIQUE LOW COST THERMAL STORAGE SYSTEM

The thermal storage tanks, pipelines, fittings and valves etc. shall be of high heat resistant and corrosion resistant steel. It is proposed to use specially designed thermal storage tanks located underground with ground support all arouns except at bottom and high temperature refractory insulation all around as well as at the bottom. The suction valve, the pipeline and the HTF circulation pump shall be located underground near the bottom of the thermal storage tank. For the thermal storage, we propose to use metallic filling in the tank made of wire mesh rolls occupying approximately 60% of the tank volume. The density of the metallic filling being more than that of the HTF, we shall have much more thermal storage than we would have had with full volume of the tank contained HTF. We can save on the initial investment in the quantity and the cost of the HTF. We shall also save on the storage tank material by way of using thinner gauge steel due to the tank being located underground and being supported by the ground mass itself. However, there could be some extra cost by the way of metallic filling inside the storage tank. But over all there should be substantial savings in the total cost of the thermal storage system with advantage of higher thermal storage capacity, possibility of generating electricity round the clock and it will be possible to adjust the power generation exactly to the demand from the grid. We propose to use synthetic oil for one part of the solar thermal collection field for generating steam to turbines. We can use molten salts with higher operating temperatures for another part of the solar thermal collection field for superheating the steam to turbines. This way, we can optimize the collected thermal energy to achieve better conversion efficiency.
WATER DESALINATION
There is great need to innovate the technology for water management to make it available in required quality and quantities and also at affordable price. Drinking water is required for population but is not available at some places mainly in rural areas. Industrial process water is required in suitable qualities for different industries. The quality of raw water from different sources is deteriorating due to pollution. Raw water from sources like lakes, rivers, underground water and seawater need to be treated and processed in order to make is suitable for drinking, industrial use etc. Desalination of raw water is generally carried out using two different technologies namely membrane technology and distillation technology. While the former requires less energy, the later needs more energy. We have developed equipment using innovative designs for minimum use of energy. Where waste energy is available, we have utilized the same for cost reduction. We also make use of renewable energy sources for water generation in order to reduce costs as well as carbon emissions contributing to the efforts to minimize global warming. Some times effluent water is used as source of raw water for recycling the water resulting in reduction in water pollution. We have capabilities to design, manufacture and commission following plants for Water and Waste Water Management using different technologies for optimizing the energy use resulting in cost reduction as well;
  • Desalination of Seawater, raw water from rivers, lakes, underground etc. using membrane technology for low energy consumption for drinking water, industrial process water etc.
  • Desalination of raw water from above sources using distillation technology with optimized use of energy for drinking water, industrial process water etc.
  • Effluent Treatment Plants for effluent water for recycling water, recovery of valuable contents in the effluent, using any of the above technologies either individually or in combination with the optimized use of energy.
  • Sewage Treatment Plants for recycling and compost.
