Steam can be generated by harvesting sun light using concentrated mirrors. This technology is being perfected during the last 10 years and more than 200 numbers of solar steam generators are being used in different parts of India. These units are working perfectly and the customer satisfaction is very high as they are getting huge savings from these units. |

| Hykon has two types of Solar Steam Generator : |
|
|
|
|
|
|
|

Block type Solar Steam Generators have a single parabolic concentrator mirror. The sun light is focused to an insulated block of solid steel. Block type Solar Steam Generators are used to produce steam at 2500 C at a low pressure. These systems are ideal for Autoclaves in hospitals. The steam produced in this system can feed to the autoclaves for sterilizing instruments. For a 150 bed hospital a system with 4 parabolic reflectors will be needed. The main parts of the system are concentrating reflector, Insulated Heat Exchanger and a Tracking device. |

• In hospitals or sterilization
• In hotels & hospitals for laundry purpose. |
|

Advantages :
• Annual saving of 40-50% on energy bills can be obtained. Usually autoclaves work with electricity or diesel. So there will be a reduction of 40-50% either on electricity bill or in
diesel bill.
• Since the steam enters very fast in the autoclave the sterilization time will be very short. So
Staffs can save a lot of time to wait through the sterilization of hospital equipments.
• Steam can also be used for washing clothes.
• 100% depreciation can be availed in the first year itself.
Disadvantages :
• During winter or cloudy days solar steam generators does not produce enough steam for
Sterilization. |

|
|
|
|
|
| |
This model is used for cooking meals for less than 100 people at a time. An opening is made in the kitchen wall at the focal point. A second reflector is used to direct the heat to a vessel with 35-40 cm diameter. The main parts of a direct heating model concentrator cooker are; parabolic reflector mirror, Secondary reflector and a Tracking device. |
|
|
| Solar Community Concentrator Cooker - Indirect heating |
|
|
|
|
|
| |
This type of Solar Concentrator cooker is used to prepare more than 10,000 meals a day. Instead of heat steam is directly used to cook the meals. The system consists of parabolic concentrating reflector, receiver, header pipe, steam storage tank and tracking system. Steam generated in the header pipe is passed through the cooking vessels to cook the meals. These solar steam generators can be easily incorporate in places where steam is used as a medium for cooking. |
